The invention belongs to the technical field of relay control, and provides a relay control circuit, a relay control device and an electric vehicle. A latch module is adopted to temporarily store a received main control signal, and output a relay control signal according to the main control signal; a first control switch module serves as a high-side control switch module; a second control switch module serves as a low-side control switch module; the first control switch module and the second control switch module form a double-side control switch circuit; and the latch module synchronously controls a high-side drive module and a low-side drive module, so that a relay is closed, the control stability of the relay is enhanced, and the failure rate of the relay is reduced, the problems that independent driving is unstable and is easily interfered when the relay is controlled by adopting an independent high side or an independent low side can be solved.

    本申请适用于继电器控制技术领域,提供了一种继电器控制电路、继电器控制装置及电动车辆,采用锁存器模块暂存接收的主控信号,并根据主控信号输出继电器控制信号,第一控制开关模块作为高边控制开关模块,第二控制开关模块作为低边控制开关模块,通过使用第一控制开关模块和第二控制开关模块组成双边控制开关电路,由锁存器模块同步控制高低边驱动模块,从而闭合继电器,增强继电器的控制稳定性,降低继电器的失效率,可以解决继电器采用单独高边或者单独低边控制继电器存在的独立驱动不稳定、容易受干扰的问题。
