Abstract

The invention provides a distributed four-wheel drive pure electric vehicle electrical system. The system comprises a power battery pack, a battery management system, a high voltage distribution box, an adapter junction box, a vehicle-mounted charger, a DCDC, an air-conditioner compressor controller, an air-conditioner compressor, a PTC, an electric controller, a motor, wheels, a remote monitoring system, a vehicle control unit, a storage battery, an ignition switch, a combination meter, a vehicle body module controller, lamplight, a low-voltage power supply relay and a high-voltage power supply relay, wherein the low-voltage power supply relay and the high-voltage power supply relay work in cooperation with the other components. The system further comprises a high-voltage direct current bus and a low-voltage output circuit for connecting the other components. According to the pure electric vehicle electrical system, some new electrical systems and devices are added, an original low-voltage circuit is modified partially, and the independent wiring mode is adopted for the newly-added electrical system, so that the whole electrical system is reliable to use and easy and convenient to operate.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a distributed four-wheel drive pure electric vehicle electrical system. Background technique [0002] An electric vehicle is a new energy vehicle in which electric energy is involved. Electric energy is converted into mechanical energy through a power device such as an electric motor to drive the vehicle. Due to environmental pollution and the gradual shortage of traditional energy sources, electric vehicles have become the focus of attention of the automobile industry in various countries. Four-wheel drive pure electric vehicles are more and more popular in the world due to their small size, high specific power, and high transmission efficiency. Admired. The existing research and development of pure electric vehicles is generally based on traditional vehicles, and the corresponding electrical systems are also developed based on traditional car electrical systems. This status q...
