The invention provides a circuit verification method, a signal verification method, a charger and a vehicle. The circuit verification method comprises the steps that when the charger is not connected with a charging gun, outputting a preset signal periodically to a signal detection circuit, and the preset signal is matched with a control guide signal of the charging gun; and judging whether the signal detection circuit is normal based on a deviation value between a signal of a preset detection point of the signal detection circuit and an ideal signal. According to the configuration, the verification of the signal detection circuit can be completed by increasing less circuit cost, and the control guide signal can be verified on the basis, so that the problem that a method and a device for verifying whether the control guide signal is normal are lacked in the prior art is solved.

    本发明提供了一种电路校验方法、信号校验方法、充电机及车辆。其中,所述电路校验方法包括:当所述充电机未连接充电枪时,周期性地向所述信号检测电路输出预设信号,所述预设信号与所述充电枪的控制导引信号相匹配;以及,基于所述信号检测电路的预设检测点的信号与理想信号的偏差值判断信号检测电路是否正常。如此配置,增加较少的电路成本就可以完成所述信号检测电路的校验,并可以以此为基础,对控制导引信号进行校验,解决了现有技术中缺乏能够针对控制导引信号是否正常进行校验的方法和装置的问题。
