The balancing circuit is the actual execution part of the balancing strategy and directly affects the efficiency of the balancing system. The basic principle of the balancing circuit is energy transfer. Specifically, the control system sends signals to control the energy transfer or release between individual cells. Balancing circuits are categorized into passive and active balancing circuits based on whether the energy of an individual cell is released due to loss or transferred to other low-energy cells. 1. Passive balancing

The electric vehicles and energy storage devices we use daily all rely on lithium-ion battery cells for power. The capacity, lifespan, safety, and waterproof/explosion-proof capabilities of these cells depend 70% on the packaging process. If electrode coating and winding are like “building the skeleton and filling the flesh” of the battery, then cell packaging is like putting on a protective suit, sealing and shaping it, and securing the safety baseline. The precision and stability of the packaging process directly determine
