The invention discloses a charging circuit and a corresponding control method thereof, a vehicle and a charger. A protection circuit is arranged in a charging circuit and comprises a current limiting branch circuit and a short circuit branch circuit, and a control circuit is used for controlling on or off of a short circuit relay, so that the current limiting branch circuit is connected to the charging circuit before a vehicle relay is conducted, and the short circuit branch circuit is connected to the charging circuit before a charger relay is conducted. Therefore, under the condition that the relay at the charger end is conducted, the current value can be reduced through the current limiting branch so as to reduce relay adhesion, and during normal charging, the current limiting branch is short-circuited through the short-circuit branch so as to reduce heat loss and heat risk of the current limiting branch and improve charging efficiency and safety.
公开了一种充电电路及其对应的控制方法、车辆和充电机。通过在充电电路中设置保护电路,包括限流支路和短路支路,通过控制电路控制短路继电器的导通或关断,以在车辆继电器导通之前,将限流支路接入充电电路,在充电机继电器导通之前,将短路支路接入充电电路。由此,可以在充电机端的继电器导通的情况下,通过限流支路减小电流值,以减少继电器粘连的情况发生,通过在正常充电时,通过短路支路将限流支路短路,以减小限流支路的热损耗和热风险,提高充电的效率和安全性。
