Problems solved by technology
[0003] In the prior art, there are usually two schemes: 1) electrothermal film heating scheme, that is, directly using resistance wire to heat the cell module, the heat transfer efficiency of this heating method is low, and the resistance wire is 2) Coolant heating scheme, this heating method requires an additional heater for heating the coolant, the structure is relatively complex, and the heat transfer is performed by the specific heat capacity of the coolant, and the heat transfer efficiency is relatively high. Low, so that the limited power resources in the battery pack can not be used efficiently, resulting in waste of power resources

Embodiment Construction
[0021] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] The "several" mentioned in this article refers to a number with an indeterminate number, usually more than two; and when "several" is used to indicate the number of certain components, it does not mean that the number of these components is the same.
[0023] With the dwindling of traditional petroleum resources, new energy vehicles such as electric vehicles and gasoline-electric hybrid vehicles are gradually entering the market. For this form of new energy vehicles, the power battery is the core component. The performance, battery life, and fast charging of the power battery etc. have also become the focus of people's research.
[0024] The performance of the power battery is greatly affected by temperature. When ...
