The invention discloses a vehicle and a high-voltage interlocking system thereof. The high-voltage interlocking system comprises a vehicle control unit, a plurality of high-voltage components and a plurality of voltage monitoring chips arranged in one-to-one correspondence with the high-voltage components. Each high-voltage component comprises a high-voltage connector and a low-voltage connector, in each high-voltage component, each high-voltage connector is electrically connected with an interlocking voltage output end of the vehicle control unit through the corresponding low-voltage connector to form an interlocking loop, and the voltage monitoring chips are connected in the interlocking loops of the high-voltage components in series in a one-to-one correspondence manner; the voltage monitoring chip is used for acquiring the voltage signal of the interlocking loop in real time and determining the interlocking state of the high-voltage components according to the voltage signal, when it is determined that a certain high-voltage component has a fault, troubleshooting is not needed one by one, the interlocking fault maintenance efficiency of all the high-voltage components is greatly improved, and the maintenance cost is reduced. And the voltage monitoring chip can be configured to adopt a relatively accurate fault detection method, so that misjudgment can be effectively avoided, and the method is simple in principle, reliable and feasible.
