1. Constant current charging: Constant current charging is a method of charging using segmented constant current. This is usually achieved by adjusting the charging device itself. Capable of freely selecting and adjusting the charging current, with strong adaptability, especially suitable for low current long-term charging, and also beneficial for charging batteries with slower capacity recovery.

2. Constant voltage charging: Constant voltage charging refers to each single cell battery being charged at a stable voltage of one ampere (usually taken as a single cell battery multiplied by 2.5V). The characteristic is that the initial charging current is quite large, and the electromotive force of the battery and the relative density of the electrolyte increase rapidly. As the charging continues, the charging current gradually decreases, and only a small amount of current is required to pass through at the end of the charging period. The charging time is short, and the energy consumption is low.

3. Fast charging: Fast charging refers to a charging method using high current. Fast charging does not produce a large number of bubbles and does not generate heat, which can shorten the charging time. Currently, there are two commonly used fast charging methods: pulse charging and high current fast charging.

4. Balanced charging: Balanced charging is a charging process that takes 1 to 3 hours at a low current (1/20C20A). Mainly used to eliminate the difference caused by the imbalance of the entire set of batteries under the same working conditions, in order to achieve the balance of the entire set of batteries, in order to eliminate a floating charging operation (a method of connecting DC power and batteries in parallel).
