Abstract

The invention provides an electric automobile battery module, which comprises a circulation air supply device, an air inlet pipe main pipeline, an air inlet pipe branch pipeline, an air outlet pipe branch pipeline, an air outlet pipe main pipeline, an air quantity homogenizing plate and battery cells. The electric automobile battery module is characterized in that a plurality of air quantity homogenizing holes are formed in the air quantity homogenizing plate; the air quantity homogenizing plate is arranged between the battery cells of the battery module; circulation air in the air inlet pipe main pipeline enters the plurality of air quantity homogenizing holes formed in the air quantity homogenizing plate through the air inlet pipe branch pipeline, so that the air quantity passing through the surface of each battery cell is identical; then, the air is guided out through connecting the air outlet pipe branch pipeline arranged at the other end of the air quantity homogenizing plate with the air outlet pipe main pipeline. According to the structure, the heating or refrigeration efficiency of the battery module is improved, so that the safety of the process is improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a battery module of an electric automobile. Background technique [0002] As the energy storage element of electric vehicles, battery modules are also one of the key components of electric vehicles, which directly affects the performance of electric vehicles. Power batteries are particularly sensitive to temperature changes. Especially the large-capacity, high-power lithium-ion batteries used in vehicles. The loading space on the vehicle is limited, the number of batteries connected to the vehicle is large, and the internal arrangement of the power supply system is relatively dense. When the vehicle is running in different states of high speed, low speed, acceleration, deceleration, etc., the battery will be discharged at different rates, and a large amount of heat will be generated at different heat rates. Coupled with time accumulation and space effects, the heat will accumulate in...
