The battery thermal insulation device includes a case 10 and a base 20, and the base 20 has a mounting region 21 for mounting a battery module 30. The case 10 covers the mounting region 21, and the case 10 and the mounting region 21 of the base 20 enclose a battery cavity 11 for accommodating the battery module 30. The base 20 is provided with a heat preservation cavity 23 at least inside the mounting area 21, and air in the heat preservation cavity 23 can reduce the speed of heat exchange between the battery module 30 and the outside through the base 20. Through reducing the speed of battery module 30 and outside heat transfer for the temperature of battery module 30 can be controlled in the best operating temperature scope, thereby can full play battery module 30's performance, guarantee simultaneously that the operating temperature of battery module 30 also can ensure the security of battery package, promote the life-span of battery package by a wide margin.
In the battery heat preservation device, the battery module 30 is arranged on the base 20 and is accommodated in the battery cavity 11, so that the battery module 30 and the shell 10 are separated from each other, and heat transmission is reduced. Meanwhile, the base 20 is provided with the heat preservation cavity 23, and air in the heat preservation cavity 23 can reduce heat exchange of the battery module 30 with the external environment through the base 20, so that the heat preservation and insulation purposes are achieved. Compare with traditional battery heat preservation device, above-mentioned battery heat preservation device need not complicated insulation construction, can be in order to reduce battery module 30's heat to external environment transmission through design heat preservation chamber 23 in base 20, and the structure is simpler, and the cost is lower, and the suitability is wider.
Optionally, the battery pack further includes a connection adhesive 32, and the battery module 30 is adhered to the mounting region 21 by the connection adhesive 32. To the new forms of energy vehicle that adopts the forced air cooling, because the calorific capacity of battery package is not big, consequently can adopt to connect gluey to install battery module 30, when easy to assemble, also can completely cut off battery module 30 and base 20 through connecting gluey 32, reduce base 20 and battery module 30's heat conduction efficiency. Further, connect gluey 32 can select the glue that has the heat preservation effect, the glue that coefficient of thermal conductivity is low promptly, can further keep warm to battery module 30 like this, reduce battery module 30 and pass through the heat dissipation of base 20.
In the embodiment of the present invention, the battery thermal insulation device further includes a thermal insulation member 12, and the thermal insulation member 12 covers the surface of the casing 10 away from the battery cavity 11. In this way, the outer surface of the casing 10 is covered with a layer of heat insulating material 12, and the casing 10 is heat-insulated by the heat insulating material 12. Although the case 10 is not in direct contact with the battery module 30, the heat of the battery module 30 is transferred to the inner surface of the case 10 through the air of the battery cavity 11 or the base 20, and the case 10 is separated from the external coil by the heat insulating member 12, so as to reduce the heat exchange efficiency between the case 10 and the external environment, and further achieve the effect of insulating the battery module 30.
Alternatively, the housing 10 may be made of PCM phase change insulation material. The PCM heat-insulating material has a small heat exchange coefficient, so that heat exchange between the shell 10 and the environment can be reduced, and heat loss of the battery module 30 is further reduced.
In some embodiments, the insulating member 12 is removably coupled to the base 20. When the heat productivity of the battery pack is too much and the temperature of the battery module 30 is too high, the heat preservation member 12 can be taken down from the base 20, so that the battery pack can exchange heat with the outside through the shell 10, and the purpose of cooling the battery pack is achieved. Or the ambient temperature is increased, when the battery is not required to be heated and insulated, such as in spring and summer, the heat-insulating piece 12 can be taken down from the shell 10, so as to better cool the battery.
