Storage batteries are suitable for pure electric vehicles, including lead-acid batteries, nickel-metal hydride batteries, sodium-sulfur batteries, secondary lithium batteries, air batteries, and ternary lithium batteries, which vary slightly depending on the type of electric vehicle. In a pure electric vehicle equipped only with a storage battery, the storage battery serves as the sole power source for the vehicle's drive system. When the automotive battery management controller is working, it will generate heat. If this heat is not dissipated in time, it will affect its working efficiency. To ensure the safe use of the battery, a heat dissipation structure for automotive battery management is proposed.
