The invention discloses a power battery low-voltage manual maintenance switch control system and a vehicle. The power battery low-voltage manual maintenance switch control system comprises a power battery pack, a battery pack circuit breaking unit, a battery management unit and a low-voltage manual maintenance switch; the power battery pack is connected with the battery pack circuit breaking unit,and the battery pack circuit breaking unit is used for completing the power battery internal power distribution function and controlling the voltage and current of a power battery high-voltage outputloop; the low-voltage manual maintenance switch is serially connected to an interlocking loop of the battery management unit and a power supply awakening loop of the battery management unit, and meanwhile, the low-voltage manual maintenance switch is connected with at least two high-voltage acquisition points in the battery pack circuit breaking unit; the battery pack circuit breaking unit is connected with the battery management unit, and the battery management unit is used for controlling a relay and high-voltage loop detection in the battery pack circuit breaking unit. Compared with a traditional high-voltage MSD, the power battery low-voltage manual maintenance switch control system is smaller in size and lighter in weight, the exposed part does not occupy the space of the whole vehicle, and the cost is low.
