Abstract
The utility model discloses a novel heat preservation battery box the bottom of box the box internal surface all around with all be provided with the heat preservation on the back of lid being provided with the exhaust hole on the box, both can having played and preserve the free temperature of battery, the hydrogen that produces when being convenient for battery electrochemical reaction is again in time got rid of, avoids arousing burning or explosion, it also is provided with the heat preservation on the free support of battery to place in the box for battery monomer and cold air are kept apart, can not freeze owing to microthermal influence results in holding battery solution, result in the monomer prostheticly to damage, still are provided with the external coating that layer nanocomposite made outside the heat preservation, better play the protection to the battery.
Description
Technical field
The utility model relates to accumulator box technical field, is specially a kind of novel temperature keeping battery case.
Background technology
Along with the development of battery industry, increasing industry starts to adopt lead acid accumulator, is wherein no lack of the enterprise of some extremely frigid zones, and when the temperature is too low, the performance of lead acid accumulator will be affected.
At lead acid accumulator charge and discharge process, there is electrochemical polarization and concentration polarization, high current charge-discharge is mainly by the impact of concentration polarization.Lead acid accumulator working temperature is down to less than 0 DEG C charging, at charging original negative pole plate, serious concentration polarization can occur, battery charge acceptance is limited, and then cause charging, discharging electric batteries obviously to reduce along with the reduction of temperature.
Battery discharges under low-temperature condition, and negative electrode active material utilance is extremely low.The lead of negative plate very easily becomes undersized crystal grain, and aperture easily frozen and blocking again, thus decrease active material utilization, fine and close sulfuric acid lead layer may be become time serious, make battery stop electric discharge.When ambient temperature is down to less than 0 DEG C, temperature often reduces by 10 DEG C, and internal resistance about increases about 15%, because sulfuric acid solution viscosity becomes large, so increase sulfuric acid solution resistance, and has increased the weight of electrode polarization impact.Battery capacity can obviously reduce, and the decline along with density of electrolyte can cause battery to freeze, and causes battery pole plates spalling, pulverizing, the damage of the unrepairables such as battery case bulge.
Utility model content
The technical problems to be solved in the utility model overcomes low temperature environment storage battery charging-discharging performances is affected, and produces the problems such as battery spalling, shell bulge, provide a kind of novel temperature keeping battery case being provided with heat-insulation layer and steam vent.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A novel temperature keeping battery case, comprises casing and lid, in the bottom of described casing, the inner surface of described casing and the back side of described lid, is provided with heat-insulation layer, described casing is provided with steam vent.
Further, the insulation material arranged in described heat-insulation layer is for there being heat-barrier material blowing agent.
Further, be provided with the support for placing battery monomer in described casing, described support is provided with heat-insulation layer.
Further, described heat-insulation layer is also provided with the external protection that layer nano composite material is made outward.
Temperature keeping battery case of the present utility model, the inner surface and described lid of the bottom of described casing, described casing surrounding are provided with heat-insulation layer, described casing is provided with steam vent, both the temperature of preserving single battery can have been played, the hydrogen produced when being convenient to again cell electrochemical reaction is got rid of in time, avoids causing burning or blast; In casing placing battery monomer support on be also provided with heat-insulation layer; single battery and cold gas are isolated; battery liquid will be caused to freeze due to the impact of low temperature; cause the damage of monomer unrepairable; also be provided with at heat-insulation layer the external protection that layer nano composite material makes outward, better play the protection to battery.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model inside.
