Switching power supply technology

The charger adopting the switching power supply technology can accurately control the charging voltage and current through the single chip microcomputer. According to the different chemical composition and charging requirements of the battery, the charging process is divided into several different stages, charging with positive and negative pulses of different frequency, different interval, different pulse width and different amplitude, so as to reduce the temperature rise of the battery, reduce the gas evolution, improve the current acceptance capacity of the battery, and extend the battery life, In corresponding applications, fast charging can also be realized according to actual needs.

Negative pulse technique

The negative pulse technology is developed under the inspiration of the American scientist Max's charging theory. Under the control of the single-chip microcomputer, it turns on and off at high speed, turns DC into high-frequency AC, improves the conversion efficiency and reduces the volume. The charging voltage and current can be accurately controlled. According to the different chemical composition and charging requirements of the battery, the charging process is divided into several different stages, and the charging is performed with positive and negative pulses of different frequency, different interval, different pulse width and different amplitude, so as to reduce the temperature rise of the battery, reduce the gas evolution, improve the current acceptance capacity of the battery, extend the battery life, and realize rapid charging. Most of the oxygen generated in the charging process will be reduced to electrolyte under the negative pulse.
