Description
Technical field
The utility model belongs to battery production and manufactures field, is specifically related to a kind of lithium ion battery with constant temperature heating device.
Background technology
Along with scientific and technological progress, increasing equipment brings into use lithium ion battery to substitute original weight is large, energy density is low lead acid accumulator, but, lithium battery requires higher to ambient temperature, especially low temperature environment is very large to lithium battery performance impact, which limits the use of lithium battery in cold district.At present, although developed the lithium battery used for low temperature environment, but still the requirement of lower temperature can not have been met, the vehicle such as using lithium battery to drive easily exist in the winter time be short of power, degradation problem under course continuation mileage.
Utility model content
The purpose of this utility model is to provide a kind of lithium ion battery with constant temperature heating device, which solves existing lithium battery causes hydraulic performance decline problem because of low temperature.
The technical scheme that the utility model adopts is, a kind of lithium ion battery with constant temperature heating device, comprise battery pack body, the outer cover of battery pack body has Aluminum Drum, power supply and the heater with function of temperature control is provided with between battery pack body and Aluminum Drum, separated by epoxy resin board between power supply and heater, between power supply and heater, be provided with temperature probe.
Feature of the present utility model is also,
Battery pack body is connected by PVC film pyrocondensation with power supply.
The two ends of Aluminum Drum are fixed with upper cover and lower cover respectively.
The beneficial effects of the utility model are, a kind of lithium ion battery with constant temperature heating device, by arranging power supply and the heater with function of temperature control, battery pack can be made to work under temperature constant state, the rapid problem of change when internal resistance of single cell declines because of ambient temperature and raises in battery pack can be reduced, improve the stability of cell, thus guarantee the consistency of cell, improve the useful life of battery pack.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of lithium ion battery with constant temperature heating device of the utility model.
In figure, 1. battery pack body, 2. power supply, 3. temperature probe, 4. heater, 5. Aluminum Drum, 6. epoxy resin board, 7. upper cover, 8. lower cover, 9. handle.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, a kind of lithium ion battery with constant temperature heating device, comprises battery pack body 1, and the outer cover of battery pack body 1 has Aluminum Drum 5, and the two ends of Aluminum Drum 5 are fixed with upper cover 7 and lower cover 8 respectively by bolt, and upper cover 7 is provided with handle 9; Power supply 2 and the heater 4 with function of temperature control is provided with between battery pack body 1 and Aluminum Drum 5, separated by epoxy resin board 6 between power supply 2 and heater 4, be provided with temperature probe 3 between power supply 2 and heater 4, linked together by PVC film pyrocondensation between battery pack body 1 and power supply 2.
The operation principle of a kind of lithium ion battery with constant temperature heating device of the utility model is, the temperature range presetting heater 4 is between 25 DEG C ~ 30 DEG C, by the temperature probe 3 monitoring of environmental temperature of the inside of battery pack, when ambient temperature is lower than 25 DEG C, battery pack automatically starts heating system and heats, the temperature probe 3 of internal battery pack feeds back to temperature control system actual temperature, thus realizes automatic constant-temperature function, ensures that battery pack is in temperature constant state always.Linked together by PVC film pyrocondensation between this device battery group body 1 and power supply 2, both can be made to become as a whole, also can not collide so in the case of a hard exercise, improve stability and the fail safe of this device, by arranging upper cover 7 and lower cover 8, can protect Aluminum Drum 5, and there is sealing function, prevent dust from falling into, improve this device lifetime; Separated by epoxy resin board 6 between power supply 2 and heater 4, can play fixation, two is that epoxy resin board 6 plays conductive force, even heat can be passed to battery pack body 1.
