The charger is a device that replenishes power to the battery. Generally, it is divided into two-stage charging mode and three-stage charging mode. Two-stage charging mode: first constant voltage charging, the charging current gradually decreases with the increase of battery voltage. After the battery power is replenished to a certain level, the battery voltage will rise to the set value of the charger. At this time, it will switch to trickle charging. Three-stage charging mode: at the beginning of charging, first charge with constant current and quickly replenish energy to the battery. After the battery voltage rises, switch to constant voltage charging. At this time, the battery energy is slowly replenished, and the battery voltage continues to rise. It reaches the charging termination voltage of the charger. When the value is reached, switch to trickle charge to maintain the battery and supply the battery’s self-discharge current.

Batteries are on-board energy sources that provide energy for electric vehicles, and electric vehicles mainly use a combination of lead-acid batteries. In addition, nickel-metal hydride batteries and lithium-ion batteries have also been used in some portable folding electric vehicles.

Tips for use: The main control board of the controller is the main circuit of the electric vehicle, which has a large working current and will emit a large amount of heat. Therefore, do not park the electric vehicle in the sun or expose it to rain for a long time to avoid malfunction of the controller.
