Commonly used balanced charging technology, including constant shunt resistance equalization charge, on-off shunt equalization charge, the average battery voltage balanced charge, switching capacitor balanced charge, buck converter balanced charge, inductive balanced charge. Group of lithium batteries in series charge, should ensure that each battery balanced charge, otherwise the use of the process will affect the performance of the entire battery and life. And the existing single-cell lithium battery protection chip does not contain balanced charge control function, multi-section lithium battery protection chip balanced charge control function requires an external CPU; and through the protection of the chip serial communication (such as I2C bus) to achieve The protection of the complexity of the circuit and design difficulty, reducing the efficiency and reliability of the system, increasing power consumption.
