Abstract

The invention discloses a heat management coupling system of a power lithium battery. An air blowing fan and an air sucking fan are respectively installed on the front side and the rear side of a boxbody; a BMS battery management system and a heat management controller are fixedly installed on one side in the box body; one end of a temperature sensor is connected at the positive electrode end ofa battery module group, and the other end of a temperature sensor is connected with the BMS battery management system; the heat management controller is signally connected with an electrical heating film, the air blowing fan and the air sucking fan; through real-time collection, analysis and processing of a temperature signal, the BMS battery management system makes the heat management controlleradopt measurements of heating, cooling or heat preservation to control the temperature of the lithium battery. The heat management coupling system ensures that the influence factor of environmental temperature on the battery pack is minimized, and therefore achieves the purposes of heat dissipation during high-temperature, heating during low-temperature and phase-change temperature control, wherein the maintenance and replace methods of the phase-change material pack are more concise and convenient, and the device makes the temperature field distribution of the battery module group more even and accordant.

Description

technical field [0001] The invention relates to the technical field of thermal management of new energy power lithium batteries, in particular to a thermal management coupling system that utilizes cooling components, heating components, heat preservation components and a BMS battery management system to manage and control the temperature of lithium battery packs. Background technique [0002] In the context of increasingly prominent environmental pollution problems, energy conservation and environmental protection have become the consensus of today's society. Due to its significant advantages in energy saving and emission reduction, electric vehicles have attracted attention both at home and abroad. The key to the development of electric vehicles is the power battery, and the electrochemical performance and cycle life of most batteries are significantly affected by temperature. Too high or too low temperature is not conducive to the performance of the battery. When the temp...
