The embodiment of the invention provides a charger and a charging system, the charger comprises a power supply plug and a function box, the power supply plug comprises a first section of a first phase line, a second phase line, a temperature elastic sheet and a ground wire, and the function box comprises a voltage detection module, a control module and a second section of the first phase line; the temperature elastic sheet is connected between the first section of the first phase line and the second section of the first phase line; when the power supply plug is inserted into the commercial power socket, the voltage detection module is used for detecting the voltage between the second end of the first phase line and the second phase line or the voltage between the second end of the first phase line and the ground wire; the control module is also used for determining whether the temperature spring is disconnected according to the voltage, and under the condition that the temperature spring is disconnected, the control module determines a protection strategy according to the accumulated disconnection times of the temperature spring after the power supply plug is inserted into the commercial power socket. The embodiment of the invention can reduce the safety risk of the charger.
本申请实施例提供一种充电器及充电系统,该充电器包括供电插头和功能盒,供电插头包括第一相线的第一段、第二相线、温度弹片和地线,功能盒包括电压检测模块、控制模块、第一相线的第二段;温度弹片连接在第一相线的第一段和第一相线的第二段之间;在供电插头插入市电插座的情况下,电压检测模块用于检测第一相线的第二端和第二相线之间的电压或者第一相线的第二端和地线之间的电压;控制模块还用于根据电压确定温度弹片是否断开,在温度弹片断开的情况下,控制模块根据供电插头插入市电插座后温度弹片的累计断开次数确定保护策略。本申请实施例可以降低充电器的安全风险。
