Hybrid balancing, simplifies the complexity. There is no need to detect the voltage difference between batteries. It directly transfers energy through adjacent capacitors and then connects them in parallel at high frequency. The single-chip microcomputer main control is matched with low-resistance MOS tubes, which has excellent low power consumption performance and high-efficiency and high-precision balancing effect. The balancing accuracy can reach 0.005V-0.01V for long-term use, and the circuit power consumption is lower. The operating power consumption is about 1.5-2.5MA. The battery cell voltage is automatically turned off when it is lower than 2.5V, or it can be turned off manually by the switch. The maximum balancing current is about 6A. The greater the voltage difference, the greater the current. When the voltage difference is 1V, it is about 6A; 0.5V is about 3A; 0.2V is about 1.2A (the above parameters are 4S power lithium batteries, with 10CM 0.75MM square, measured, and the voltage acquisition measurement point is the onboard plug). It can be expanded and combined. According to the battery series connection method, select the appropriate module combination, and the module can be reduced or extended. It can be reduced or multi-board cascaded for expansion.
