AI Technical Summary
Lithium batteries experience temperature increases during prolonged operation, triggering charging protection mechanisms, reducing battery life, and making them less user-friendly.
A motor-battery pack assembly with cooling function was designed, including a fan cover, battery compartment, battery cells, PCB box, PCB board, PCB cover, motor and heat dissipation components. The heat dissipation fan blades and guide plates form an air duct to remove the heat from the battery cells, and the sealing structure ensures airtightness.
It effectively reduces cell temperature, prevents overheating protection, extends cell lifespan, and reduces usage costs.
