The invention provides a uniform distribution type heat management system and a battery. The battery comprises multiple battery modules; the uniform distribution type heat management system comprises multiple heat management devices, wherein the heat management devices comprise heat transfer components which are arranged between two adjacent battery modules and are used for transferring heat, heat generation components which are attached to the heat transfer components and control components which are connected with the heat transfer components and the heat generation components; the control components control the heat generation components to heat the heat transfer components. The heat transfer components are separately heated through each heat generation component attached to the corresponding heat transfer component; afterwards, the heat transfer components transfer the heat to the battery modules. In this way, the more accurate temperature control can be carried out on the battery modules at different temperatures in a more targeted manner; moreover, the heat transfer components are uniformly heated; temperatures received by the battery modules are enabled to be also more uniform.
Description
technical field [0001] The invention relates to the technical field of battery thermal management, in particular to a uniformly distributed thermal management system and a battery. Background technique [0002] As the main energy storage component of electric vehicles, battery modules are key components of electric vehicles and directly affect the performance of electric vehicles. When the vehicle is running under different driving conditions such as high speed, low speed, acceleration, deceleration, etc., the battery modules will be discharged at different rates, and a large amount of heat will be generated at different heat generation rates, resulting in uneven heat distribution. At this time, it is necessary to control the temperature of the battery module through the thermal management system, so that the temperature of each battery module is basically the same, and prevent the different discharge states of each battery module due to uneven temperature, resulting in shor...
