Double-line redundancy safety high-voltage equipment of light bus and control system and method thereof

The invention provides double-line redundancy safety high-voltage equipment of a light bus and a control system and method thereof. The equipment comprises a power battery set, a power management system unit, a motor controller, high-voltage accessories, a whole-bus controller and a driving motor. The power management system unit, the motor controller and the high-voltage accessories are connected between a positive electrode and a negative electrode of the power battery set through high-voltage cables. The whole-bus controller is connected to the power management system unit, and the driving motor is connected to the motor controller. The power battery set comprises at least two battery packs connected in parallel, and at least one battery pack provides power in operation of a double-line redundancy safety high-voltage system of the light bus. Through the battery packs connected in parallel, power is supplied to the whole light bus; when one battery pack fails, other battery packs can still guarantee that the light bus operates at preset rated power, sufficient time is reserved for the light bus on which the electric failure happens so that the light bus can reach a safe position, and then safety of a driver and passengers can be guaranteed.
