Description

technical field [0001] The present invention relates to the technical field of battery temperature control, and more specifically, to a battery thermal management system. Background technique [0002] As an essential core component of new energy vehicles, power batteries provide power energy for electric vehicles, and lithium-ion batteries are recognized by the market as energy storage systems for electric vehicles due to their high energy / power density, low self-discharge rate, and long life. And the mainstream choice of energy storage power station. However, the performance degradation of lithium-ion batteries caused by thermal safety issues hinders its further promotion and application. [0003] Among the existing heat dissipation technologies for power batteries, the ones that have been used in large-scale commercial applications are mainly air-cooled and liquid-cooled heat dissipation. The traditional air-cooling mode mostly focuses on the arrangement of battery packs...
