The invention discloses a vehicle and a high-voltage loop protection system and method thereof, and relates to the technical field of electric vehicles. The vehicle comprises a vehicle control unit, and the vehicle high-voltage loop protection system comprises at least one first protection loop. The first protection loop comprises a current sensor and an active excitation fuse; the vehicle control unit is electrically connected with the current sensor and the active excitation fuse and used for obtaining an actual current signal, detected by the current sensor, of the first protection loop and controlling the working state of the active excitation fuse according to the actual current signal and a preset current signal. According to the technical scheme, the current sensor and the active excitation fuse are arranged in the first protection loop, and the vehicle control unit controls the working state of the active excitation fuse according to the actual current signal and the preset current signal detected by the current sensor; the safety risk of a high-voltage loop under the overcurrent or short circuit condition is reduced, and therefore the safety of a vehicle is improved.

    本发明公开了一种车辆及其高压回路保护系统、方法,涉及电动汽车技术领域。车辆包括整车控制器,车辆高压回路保护系统包括至少一个第一保护回路;第一保护回路包括电流传感器和主动式激励熔断器;整车控制器分别与电流传感器和主动式激励熔断器电连接,用于获取电流传感器检测的第一保护回路的实际电流信号,并根据实际电流信号和预设电流信号控制主动式激励熔断器的工作状态。本发明的技术方案通过在第一保护回路中设置电流传感器和主动式激励熔断器,并通过整车控制器根据电流传感器检测的实际电流信号和预设电流信号控制主动式激励熔断器的工作状态,以降低高压回路在过流或短路情况下的安全风险,从而提升车辆的安全性。
