Project Description

The barrel principle of the battery pack discharge test is that the capacity of the battery pack depends on the worst performance of the battery.

When the battery is discharged, the battery with a small capacity must first emit all the available energy, and then the system immediately stops discharging. Therefore, the battery with a small capacity is always fully filled, and the battery with a large capacity is always only using part of the capacity, that is, the capacity of the entire battery pack is always part of the idle state. In addition, the life of the battery pack is also determined by the battery with the shortest life.
