Description
technical field [0001] The present disclosure relates to the technical field of power batteries, in particular to a novel battery thermal management system and an electric vehicle. Background technique [0002] Power batteries are the core components of new energy electric vehicles. The thermal management system of the battery is used to ensure that the battery can work normally at an appropriate temperature. With the development of new energy vehicles, higher requirements are put forward for the thermal management system of its power battery. At present, the mainstream solution for electric vehicles on the market is to use coolant to cool and heat the battery. This scheme is the most mature, but there are also certain problems. In the process of cooling and heating the battery, it is necessary to cool and heat the coolant first, which leads to a long response time of the thermal management system, consumes a lot of energy, and reduces the cruising range. Contents of th...
