The balancing current represents the average operating current of each battery cell in the battery pack. The equilibrium starting point means that the voltage difference of each battery cell in the battery pack cannot exceed a certain set value.
Selecting the appropriate battery balancer depends on several factors: Battery chemistry: Ensure compatibility with the specific battery type (e.g., lithium-ion, LiFePO4, lead-acid). Number of cells: Choose a balancer that supports the required number of cells in series. Balancing current: Consider the required balancing speed and efficiency.
The theory is that balanced cells all discharge at the same rate, and therefore cut-off at the same voltage every time. This isn’t always true, so having a balancing circuit (or PCM/BMS) ensures that upon charging, the battery cells can be fully balanced to maintain the battery’s design capacity and to become fully charged.
With quality components, this charging system can match commercial lithium-ion chargers, though it will produce more heat. The experiments demonstrated that the balancing circuit functions optimally. The charging process reaches completion upon attaining the designated voltage of 4.2 Volts. Overall, I would recommend utilizing this circuit.
Prevent the battery from being damaged by excessive current. Important technical parameters of lithium battery protection boards include overcharge protection, over-discharge protection, over-current protection, short-circuit protection, temperature protection, internal resistance, power consumption, etc.
Battery balancing works by redistributing charge among the cells in a battery pack to achieve a uniform state of charge. The process typically involves the following steps: Cell monitoring: The battery management system (BMS) continuously monitors the voltage and sometimes temperature of each cell in the pack.
