Power supply and distribution system without energy storage unit for special electrically-driven vehicle and control method of power supply and distribution system

Abstract

The invention discloses a power supply and distribution system without an energy storage unit for a special electrically-driven vehicle and a control method thereof, and the system comprises a high-voltage power supply module which is used for providing stable high-voltage DC electric energy and does not depend on the energy storage unit; the integrated control module is electrically connected with the high-voltage power supply module and is used for realizing high-voltage electric energy distribution, electric energy conversion and power supply loop control; the low-voltage power supply module is electrically connected with the integrated control module and used for receiving the low-voltage electric energy output by the integrated control module and providing stable low-voltage direct-current electric energy; wherein the high-voltage power supply module, the integrated control module and the low-voltage power supply module work cooperatively, and integrated power supply of the electric equipment mounted on the special electric-driven vehicle and the electric equipment for chassis driving is achieved. The invention aims to eliminate the safety risk caused by the energy storage unit, realize the integrated design of top-mounted power supply and driving power supply, improve the electric energy conversion stability and the system integration degree, and ensure the reliable operation of the special vehicle in a complex environment.
