Description

technical field [0001] The invention belongs to the field of batteries, in particular to a pulse charging method and device. Background technique [0002] The benefits of using pulse charging to charge and discharge batteries have been proved by a large number of theories and experiments in the industry. Usually, the problem of fast charging and discharging of the battery can be solved by adopting appropriate current and voltage values, charging and discharging time and frequency, plus the control and management part, and at the same time prolonging the cycle life of the battery. [0003] At present, the relatively advanced generation and control methods of charge and discharge pulses and special-purpose integrated circuits or single-chip microcomputer chips have made important progress on the technical level, and various hardware performances have been greatly improved. There is still a lot of room for improvement in the overall charging effect of the pulse charging techno...
