The invention discloses a vehicle-mounted charger and an electric vehicle. The vehicle-mounted charger comprises a microprocessor and a DC module, a first sampling point is arranged between the DC module and a storage battery, and a second sampling point is arranged between the storage battery and the microprocessor; the microprocessor is configured to obtain a first voltage value and a current value of the first sampling point and obtain a second voltage value of the second sampling point; and when the first voltage value is greater than the second voltage value and the current value is smaller than a preset current threshold value, marking that the connection between the storage battery and the DC module is disconnected, and recording a first difference value between the second voltage value and the first voltage value. According to the invention, broken line detection is carried out through the sampling information of the two sampling points, so that the accuracy of broken line detection is improved.

    本申请公开了一种车载充电机和电动汽车。其中,该车载充电机包括微处理器和DC模块,DC模块与蓄电池之间设置第一采样点,蓄电池与微处理器之间设置第二采样点;该微处理器被配置成:获取第一采样点的第一电压值和电流值,和获取第二采样点的第二电压值;当第一电压值大于第二电压值,且电流值小于预设电流阈值,则标记蓄电池与DC模块之间的连接断开,并记录第二电压值和第一电压值的第一差值。本申请通过两个采样点的采样信息进行断线检测,从而提升了断线检测精准度。
