Abstract

The embodiment of the invention discloses a high-voltage system for a vehicle, a method for protecting the high-voltage system and the vehicle, relates to the technical field of vehicles, and can solve the problems that in the prior art, the requirement of a dual-drive motor system cannot be met, the final assembly process is complex, and the whole vehicle is heavy. According to the system, a power battery is electrically connected with a dual-motor controller, a first heater, an air conditioner compressor and a charging and distribution unit; the dual-motor controller is electrically connected with a generator and a first driving motor respectively; a charging and distribution unit is electrically connected with a direct-current charging interface, an alternating-current charging interface, a second heater and the motor controller respectively; the motor controller is electrically connected with a second driving motor; and a first high-voltage power distribution unit is integrated in the power battery, and a second high-voltage power distribution unit, a vehicle-mounted charger and a DC-to-DC power supply are integrated in the charging and power distribution unit. The embodiment of the invention is mainly suitable for an automobile high-voltage system.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of automobiles, and in particular, relate to a high-voltage system for a vehicle, a method for protecting the high-voltage system, and the vehicle. Background technique [0002] With the development of society, cars have become an indispensable means of transportation for people. And in order to improve the environment, electric vehicles are increasingly favored by people. However, compared with ordinary fuel vehicles, electric vehicles have poor battery life. In order to reduce the number of charging, people have invented a range-extending electric vehicle, which can use the range extender to generate electricity, charge the power battery, and increase the cruising range. [0003] High voltage systems are indispensable when developing electric vehicles. However, the current range-extended electric vehicles are often based on the single-drive motor high-voltage system developed base...
