Abstract
As long as an excessive current situation exist, danger caused by heating a battery through excessive battery current is effectively avoided by keeping a thermosensitive cut-off device in a turn-off state, and an inner case arranged in the sealed space between the battery and the shell accommodates the cut-off device and a heating resistor in parallel connection with the cut-off device. Double-layer thermal insulation enables the heating resistor to conduct joule heat to the adjacent cut-off device in a highly efficient way, and the efficient utilization of space thermal conductivity can also reduce the battery current after the power is cut off, and cause no size enlargement of a battery pack.
Description
The present invention relates to comprise the battery component (a batterypack) of temperature-sensitive shearing device, this shearing device can cut off electric current when having the out-of-date or battery temperature of overcurrent to raise unusually.
As shown in Figure 1, former battery component is equipped with a thermal switch as temperature-sensitive shearing device (11).Shown in the circuit diagram of Fig. 2, the moving switch series of temperature-sensitive shearing device (21) instant heating wherein is associated between the battery (2B) and the charging utmost point (22).Thermal switch is one can forward switch the safety device of off status to stop to charge to when battery over charge and temperature rising.Though when battery temperature raise, thermal switch turn-offed and cuts off electric current in charging process, when electric current was cut off, because temperature reduces, thermal switch was connected once more.The shortcoming of this device is when battery temperature descends, and charge current flows is arranged again, then battery will charge once more again excessive.
For fear of this problem, developed a kind of battery component as shown in Figure 3, include the safety device (3A) that moves the heating resistor (33) of switch (31) parallel connection with temperature-sensitive shearing device instant heating.Shown in the circuit diagram of Fig. 3, because the heating resistor (33) of battery component and battery (3B) coupled in series, when thermal switch turn-offed, current bypass was through heating resistor (33).As shown in Figure 4, heating resistor (43) tightly is associated on the moving switch of temperature-sensitive shearing device (41) instant heating.By-pass current by heating resistor (43) causes having produced to the thermal switch heating and prevents that it from returning the Jiao Erre of on-state.What Fig. 5 showed is a battery component with circuit shown in Figure 3.Fig. 5 has shown the safety device (5A) that is installed in battery (5B) surface.Fig. 6 is plane graph, front view and the upward view that is installed in the safety device on the battery component among Fig. 5.As shown in Figure 6, heating resistor (63) is fixed on the position of being close to temperature-sensitive shearing device (61) surface.
So the structure of the battery component of interior device safety device can prevent, rise at battery temperature, thermal switch closes has no progeny, and to reclose the battery charge that causes excessive owing to thermal switch.But, such battery component, even when thermal switch turn-offs, charging current can not be reduced to zero, this is because the electric current of the heating resistor of flowing through flows through battery pack too.
Square multiply by resistance value and increase with being directly proportional of the Jiao Erre of resistance and electric current, and excessive for preventing to charge, just must reduce battery current, also must increase the heating resistor resistance to increase Jiao Erre.Yet in fact, when heating resistor was done quite greatly, Jiao Erre reduced on the contrary.This is because it is limited that battery charger offers the voltage of battery component, reduces so electric current increases with resistance.According to the voltage that battery charger provides, the increase that square is directly proportional of the Jiao Erre of heating resistor and supply voltage, being inversely proportional to resistance reduces.For this reason, keeping thermal switch to be in the resistance of the heating resistor of off state can not be very big.In other words, after thermal switch turn-offs, be difficult to make the charging current of battery to become very little.Thereby prevent that in order to reduce charging current the charging of battery is excessive, the Jiao Erre that reduces heating resistor is very important, but makes the heat that is produced can heat thermal switch effectively again.
As Fig. 4, shown in Figure 5, if heating resistor (43,53) is installed in the outside of the moving switch of temperature-sensitive shearing device (41,51) instant heating, then the Jiao Erre of heating resistor generation is difficult to be sent to efficiently thermal switch.This is because as indicated in the arrow among Fig. 4, heat has fallen from the ambient radiation of heating resistor (43).Because heating resistor (43) can not efficiently heat thermal switch, in battery component, increase the heating resistor (43) that produces heat so be necessary to design one, and necessaryly design the heating resistor value smaller, so that after thermal switch turn-offs, produce big electric current.This has electric current to flow through when just having brought and being in off state because of thermal switch to make the excessive problem of battery charge, and excessive for fear of charging, make the electric current in the heating resistor is extremely important as far as possible for a short time.In order to reach this purpose, heating resistor heats the temperature-sensitive shearing device efficiently and is necessary.And be necessary to reduce the heat that gives off from heating resistor as far as possible.
In addition, in as Fig. 4, battery component shown in Figure 5, heating resistor fixedly is attached to the temperature-sensitive shearing device promptly on as shown in Figure 6 the thermal switch, so, it is big that the overall dimension of safety device becomes, when between the battery that safety device is placed on battery component, safety device will protrude or exceed the thickness of battery component as shown in Figure 5.The shortcoming that has the battery component of projection is exactly must additionally increase the space of depositing in order to hold battery.
Another shortcoming that has the battery component that is fixed on the outer heating resistor of thermal switch is the quantity of parts, and production craft step and cost all have increase.
The objective of the invention is to address these problems.Basic purpose of the present invention provides the battery component of an energy at improper situation incision outage pond electric current, keeps the temperature-sensitive shearing device to be in off state with very little electric current, and dwindles the internal security device size to reduce volume as far as possible.Above-mentioned and other purpose of the present invention by following specific descriptions and consult accompanying drawing will be more very clear.
Battery component of the present invention comprises a plurality of batteries; A shell that holds battery; A temperature-sensitive shearing device of connecting with battery, when battery temperature surpassed a certain set point, this device was in off state; The inner box of a device temperature-sensitive shearing device; A heating resistor also is contained in this inner box.This inner box is installed in the space that is surrounded by battery and shell, and can conduct the heat of battery to the temperature-sensitive shearing device in the inner box heating resistor and the parallel connection of temperature-sensitive shearing device.In addition, heating resistor also is contained in the inner box that the temperature-sensitive shearing device is housed, and this means that heating resistor just can reduce the thermal loss that causes owing to external radiation by inner box and the two-layer thermal insulation of shell.When the temperature-sensitive shearing device is in off state, thereby because of there being by-pass current to produce Jiao Erre by making heating resistor.Heating resistor connects with the temperature-sensitive shearing device by heat conduction, and with being contained in the inner box, keeps it to be in off state thereby the Jiao Erre of heating resistor directly heats the temperature-sensitive shearing device.
In addition, battery component of the present invention preferably also comprises a forced cut-out resistance, forced cut-out resistance and temperature-sensitive shearing device coupled in series, and owing to the electric current by battery produces Jiao Erre.This Jiao Er hotwork is used for forcing the temperature-sensitive shearing device that turn-offs.Forced cut-out resistance and temperature-sensitive shearing device are with being contained in the inner box.Provide Jiao Erre with adorning a heating resistor and the forced cut-out resistance in the inner box for the temperature-sensitive shearing device with the temperature-sensitive shearing device.Forced cut-out resistance can heat it when the temperature-sensitive shearing device is in on-state, and can turn-off the temperature-sensitive shearing device when having overcurrent to flow through in the battery.

Battery component of the present invention has an inner box that is among the space that is surrounded by battery and shell.A temperature-sensitive shearing device and a heating resistor are housed in the inner box, and heating resistor is covered so that heat insulation by bilayer.Heating resistor is by battery case and the two-layer covering of inner box.This has just reduced heating resistor and has outwards dispelled the heat, and the heat that can produce heating resistor efficiently send the temperature-sensitive shearing device to.Moreover because heating resistor and temperature-sensitive shearing device are contained in the inner box together, the Jiao Er heat energy that is produced by heating resistor directly heats the temperature-sensitive shearing device.This is because inner box is to wrap heating resistor and temperature-sensitive shearing device rather than be clipped in cause between them.In having the battery component of structure like this, improved from the heat effect of heating resistor in the inner box to the temperature-sensitive shearing device, by the double thermal insulation of shell and inner box, the thermal losses that causes because of radiation reduces.
In the battery component that the Jiao Erre of heating resistor efficiently heats the temperature-sensitive shearing device, when the temperature-sensitive shearing device was in off state, the charging current by battery just can be reduced.When the transmission of the heat from heating resistor to the temperature-sensitive shearing device does not have leakage loss, then need not produce excessive Jiao Erre by heating resistor.Therefore, can determine a high heating resistor value,, and prevent that the charging when the temperature-sensitive shearing device is in off state is excessive so that reduce charging current.
See the battery component shown in Fig. 7 back, cylindrical battery (7B) marshalling and four of every rows are linked together, and battery surface is with the tubular outer shell of one deck pyrocondensation.Because tubing is book very, the overall dimension with battery component of pyrocondensation tubular outer shell can be done very for a short time.But though not expression among the figure, battery component of the present invention also can be used the plastic production shell, and plastic casing can be made the square box shape to hold a plurality of batteries.
Battery component shown in Fig. 7 has a safety device that places in the closed channel shape space (711) that is pressed from both sides by shell (76) and battery (7B).This safety device (7A) comprises heating resistor and the temperature-sensitive shearing device that places inner box (74) together.Heating resistor in interior can be prevented the radiation consumption of heat effectively by shell (76) and inner box (74) double thermal insulation.Shown in Figure 8 is and the corresponding circuit diagram of the battery component of Fig. 7.In the battery component of making by this circuit diagram, the temperature-sensitive shearing device (81) that is equipped with in the inner box is connected with battery (8B) between the battery (8B) and the charging utmost point (82).When the temperature anomaly of battery (8B) raises and turn-off temperature-sensitive shearing device (81), the safety device (8A) that is connected with the charging utmost point (82) will stop charging.In order to prevent to produce overcurrent in the battery discharge procedure, between battery and discharge electrode, a safety device is connected on the battery.
As shown in Figure 8, in parallel with temperature-sensitive shearing device (81) with temperature-sensitive shearing device (81) with the heating resistor (83) that is installed in the inner box.When temperature-sensitive shearing device (81) when being in off state, heating resistor (83) can prevent that it from returning conducting state, and heating resistor (83) keeps temperature-sensitive shearing device (81) to be in off state by Jiao Erre.
What Fig. 9 showed is the cross-section structure of safety device (9A).Safety device among this figure (9A) has adopted bimetal leaf (91A) in temperature-sensitive shearing device (91).All the time a heating resistor (93) that pastes tightly mutually with bimetal leaf is housed in the inner box (94).The inner box of the safety device shown in this figure (9A) is plastic products.Plastics inner box (94) among Fig. 9 is tubular, left end sealing, right-end openings.Shown in the horizontal section of Figure 10, inner box places in the closed channel shape space (1011) between the cylindrical battery (10B).Moreover the both sides of inner box are inclined-plane (104A), so that increase the contact-making surface of it and battery (10B).The plane of structure profile of the amplification that is mounted in the enclosure space (1011) of depositing inner box (104) between battery (10B) and the shell (106) that Figure 10 shows.Shown in arrow among Figure 10, the heat that produces by battery (10B) conduct to efficiently near or be close on the inner box of battery surface.At last, inner box shown in Figure 10 has one not to be projected into the flat of battery component outer surface.
Inner box among Fig. 9 (94) has a fixed contact (97) on the bottom surface.Its right-hand member stretches out inner box (94).The right-hand member of the movable contact (98) of bimetal leaf (91A) is fixed in the inner box (94), and it is movable that the position of its left end then is convenient in inner box.The electric contact that is positioned at movable contact (98) left end and fixed contact (97) left end is fixed on inner box (94) lining.Right-hand member one side of movable contact (98) is heated resistance (93) and insulating material (910) and is clipped in the middle and is fixed on inner box (94) lining.The movable contact (98) of bimetal leaf (91A) links to each other with the leads (99) that stretches out from inner box (94) right-hand member.The opening of inner box right-hand member is also used insulating material (910) sealing, and leads (99) and fixed contact (97) are from stretching out here.
The movable contact (98) of bimetal leaf (91A) is in conducting state by joining with fixed contact (97).But when temperature rose to a set point because of heating, movable contact (98) moved and breaks away from fixed contact, so device is in off state.The heating resistor (93) that keeps bimetallic temperature-sensitive shearing device (91) to be in off state is positioned between the contact of bimetal leaf (91A).How many resistances of heating resistor regulates by the quantity of the carbon of adding resistance jointing material.Yet the fine wire of high value such as nichrome wire also can be used for heating resistor.The resistance of heating resistor should design enough for a short time so that make Jiao Erre keep bimetal leaf to be in off-state, and is enough big again so that generation does not cause the excessive electric current of battery charge.As shown in Figure 9 heating resistor (93) is placed between bimetal leaf (91A) contact, just can make heating resistor (93) that the heating of bimetal leaf 9A is reached peak efficiency.
The right-hand member of the inner box of the safety device among Fig. 9 is sealed by fixed contact (97), insulating material (910) and leads (99).Characteristics with battery component of the sealing inner box of adorning temperature-sensitive shearing device and heating resistor are: the thermal radiation of inner box is prevented that effectively heating resistor is very high to the efficiency of heating surface of temperature-sensitive shearing device.This is because the air in the inner box can not circulate with the external world.But, always be not to be necessary, leak even if allow the air expanded by heating in the inner box to the air closed structure of inner box, still can stop the ventilation of system, also can stop the thermal radiation consumption of heating resistor effectively.Clearly, inner box also can adopt the not closed structure of leakage air.An inner box that seals fully must design to such an extent that have enough intensity to prevent because of the pressure-air that temperature in the box raises and air expansion is caused inner box being broken.
If the inner box that is installed in the battery component confined space is made of plastics, it just has insulating property (properties).This ambroin inner box just can be placed on directly and the contacted place of battery case, and contact just can contact with the sealing inner box with leads in the box.But in battery component of the present invention, the regulation inner box must not be plastics, and it also can be made of metal.Just the metal inner box must just can contact with battery by insulating material, and contact and leads must separate with insulating material in the box.The advantage of metal inner box is heat conduction usefulness height.
In battery component shown in Figure 11, forced cut-out resistance (115) and temperature-sensitive shearing device (111) coupled in series.The safety device (11A) that forced cut-out resistance (115) are housed with and the same mode of the shown battery component of prior figures 7, Figure 10 be installed in the space between battery and the shell.As shown in figure 12, forced cut-out resistance (125) and temperature-sensitive shearing device (121) just bimetal leaf (121A) are connected, and with temperature-sensitive shearing device (121) and heating resistor (123) with being contained in an inner box (124) lining.Forced cut-out resistance (125) by Jiao Errejia thrermostatic bimetal-plate (121A) to force its shutoff.When overcurrent flows through battery, also flow through the forced cut-out resistance (125) that produces Jiao Erre, the temperature-sensitive shearing device is that bimetal leaf (121A) is heated by Jiao Erre, disconnects then.In this safety device (12A), bimetal leaf (121A) is by the current flow heats of battery (12B).Therefore, the characteristics that the battery component of this safety device (12A) is housed are when overcurrent flows through battery, and bimetal leaf (121A) disconnects with the protection battery.
Bimetal leaf (121A) is connected on just can guarantees between movable contact (128) and the leads (129) that forced cut-out resistance (125) adds thrermostatic bimetal-plate (121A) efficiently.This also reaches movable contact (128) with regard to the Joule heat that makes bimetal leaf (121A).It is that electric current by the forced cut-out resistance (125) of flowing through causes that voltage reduces, so the forced cut-out resistance value will design as far as possible for a short time.If but the resistance of forced cut-out resistance (125) is too little, the Jiao Erre that its produces also incites somebody to action very little so that can not effectively heat bimetal leaf.The resistance of forced cut-out resistance should be according to battery capacity, voltage drop, and the amount of required Jiao Erre select optimal values.
In safety device shown in Figure 12 (12A), forced cut-out resistance (125) is placed between bimetal leaf (121A) movable contact (128) of leads (129) and temperature-sensitive shearing device (121).Carbon dope adhesive (binder) or metallic resistance silk have also been used as heating resistor (123) forced cut-out resistance (125).In the safety device among Figure 12 (12A), forced cut-out resistance (125) directly contacts with bimetal leaf (121A).This structure has guaranteed that Jiao Erre is from the efficient conduction of forced cut-out resistance (125) to bimetal leaf (121A).
Being equipped with as shown in figure 12, the battery component of the safety device of structure reaches the temperature-sensitive shearing device to heat so that the latter is turn-offed fast efficiently from forced cut-out resistance.Therefore, the characteristics of such battery component are: when excessive battery current flow through, as when the battery short circuit, the temperature-sensitive shearing device was activated the cut-out battery current, and then has protected battery.
Because the double thermal insulation that forced cut-out resistance and heating resistor have shell and inner box to form, forced cut-out resistance can efficiently heat the temperature-sensitive shearing device, so the resistance of forced cut-out resistance can be very little, and the operate time of temperature-sensitive shearing device can be very short.The action message of decapacitation acquisition temperature-sensitive shearing device is outer like this can also reduce the effective consumption that voltage descends and caused because electric current flows through forced cut-out resistance.
At last, see battery component among Figure 13.Heating resistor (133) is the device (133A) of a positive temperature coefficient (PTC).From the profile of Fig. 9 as can be known, heating resistor 93 also is a ptc device.Ptc device (133A) is that a kind of resistance raises and the quick device that increases with temperature.Therefore, when the temperature of bimetallic temperature-sensitive shearing device (131) reached its operating temperature, the resistance of ptc device (133A) also increased thereupon.When bimetal leaf moved to off-state, a large amount of Jiao Erre was given birth in the miscarriage of the resistance of the ptc device of flowing through, and these heats act on bimetal leaf and keep it to be in off-state.When bimetal leaf was failure to actuate and be in conducting state, the resistance of ptc device was extremely low.So, when the contact of bimetal leaf is in attracting state, battery current the in parallel of bimetal leaf and ptc device of flowing through.Because the resistance of the bimetal leaf contact of adhesive is far smaller than the resistance of ptc device, most of electric current flows through the contact of bimetal leaf.Yet if the resistance of bimetal leaf is owing to problems such as similar contact resistance increase, battery current is with bypass process ptc device.Even the characteristics of this system are to run into the bimetal leaf contact problems, battery component still can use.
In the battery component with inner box of adorning bimetal leaf and above-mentioned ptc device, when the temperature of bimetal leaf reached operating temperature, concerning the electric current of certain limit, the resistance of ptc device became very big and produces flood tide Jiao Erre.This effect is added ptc device is placed the most effective heating that will cause again between the bimetal leaf contact bimetal leaf.So the characteristics of this system are by flowing through the little electric current of ptc device, can preventing effectively that the contact of bimetal leaf from recovering on-state.
In above embodiment, heating resistor directly contacts with being loaded in the inner box and with the temperature-sensitive shearing device with forced cut-out resistance.This safety device causes Jiao Erre to transmit the most efficiently to temperature-sensitive cut-out resistance from heating resistor and forced cut-out resistance.But battery component of the present invention does not also require that heating resistor and forced cut-out resistance remain regularly and directly contacts with the temperature-sensitive shearing device.For example, although accompanying drawing does not show that heating resistor or forced cut-out resistance and temperature-sensitive shearing device can pass through additional metal or plastics conduction Joule heat so that the temperature-sensitive shearing device is heated at a distance of nearer between the two.
The present invention can give specific implementation with some other form on the basis that does not deviate from its aim and key property.Because scope of the present invention is to be determined by following additional claims, rather than it is determined by above-mentioned description, so above-mentioned instantiation only has explanatory but does not possess restriction, and every variation that meets following claim and scope or these require and the equivalents of scope also all is considered as being included in claims.
