The shape design of lithium batteries (cylindrical, square, button shaped, etc.) is a comprehensive reflection of their performance, manufacturing process, and application scenarios. The reason why cylindrical and square lithium batteries have become mainstream is that they each have advantages in terms of technological maturity, manufacturing processes, performance, and application scenarios. （1） High technological maturity Cylindrical battery: Cylindrical batteries (such as 18650) are th …

Hardware implementation Balancing circuit: Design balancing circuits (such as resistors, capacitors, inductors, DC-DC converters, etc.) to achieve energy transfer or dissipation. BMS (Battery Management System): BMS is responsible for monitoring the battery status and controlling the balancing process. software implementation Balancing strategy: Based on parameters such as voltage, capacity, and temperature of the battery, formulate balancing strategies (such as voltage based balancing and c …

1.Passive equilibrium (dissipative equilibrium) Principle: By discharging through resistance, the energy of the battery with higher voltage is dissipated in the form of heat, making its voltage consistent with other batteries. Advantages: Simple circuit and low cost. Disadvantages: Energy waste, low efficiency, suitable for small capacity battery packs. 2.Active equilibrium (non dissipative equilibrium) Principle: Through energy transfer, the energy of batteries with higher voltage is transferre …
