Description

technical field [0001] The present disclosure relates to the technical field of power battery thermal management, in particular to a heat dissipation and heat preservation system for a power battery that uses temperature difference to generate electricity with low energy consumption, which can be applied to various vehicle bodies, especially new energy vehicles. Background technique [0002] Power batteries are an important part of new energy vehicles. The operating temperature of the battery is the main parameter affecting its operating performance and life. According to experimental research, when the ambient temperature of the battery pack is too low or too high, the service life of the battery is affected. In addition, when the battery works under low temperature conditions, the chargeable capacity and dischargeable capacity of the battery decrease, which directly affects the cruising range of the power battery, and the discharge voltage of the battery decreases under l...
