• Charger, usually refers to a device that converts alternating current into low-voltage direct current. The charger is a special dc power supply for rechargeable batteries. It includes control circuits for current limiting and voltage limiting to meet charging characteristics. Charger is widely used in various fields, especially in the field of life is widely used in electric cars, flashlights and other common electrical appliances. It generally charges the battery directly without any intermediary device or device. The process of the charger is: constant current - constant pressure - trickle flow, and third-order intelligent charging. The three-stage charging theory in the charging process can greatly improve the charging efficiency of the battery, shorten the charging time and effectively extend the battery life. Three-stage charging adopts constant current charging, constant voltage charging, and floating charging for maintenance and charging.

• In general, it can be divided into three stages: quick charge, charging up, and trickling charge: quick charge stage: charging the battery with a large current to quickly restore the battery power. The charging rate can reach 1C. At this point, the charging voltage is low, but the charging current will be limited within a certain value range. Supplementary charging stage: compared with the rapid charging stage, supplementary charging stage can also be called the slow charging stage. When the rapid charging stage is terminated, the battery is not fully sufficient, and the charging process should be added. The charging rate should generally not exceed 0.3c. Since the battery voltage increases after the rapid charging stage, the charging voltage in the supplementary charging stage should also be increased and kept within a certain range. Trickle-current charging stage: in the late charging stage, when the detection degree rises beyond the limit or the charging current decreases to a certain value, a smaller current is used for charging until a certain condition is met and the charging ends.
