Abstract

The invention provides an energy management system for high-voltage accessories of an electric vehicle. The system is characterized by comprising a vehicle control unit, a battery management system and high-voltage accessories, and the vehicle control unit, the battery management system and the high-voltage accessories are in communication connection with a CAN (Controller Area Network) bus. The battery management system and the high-voltage accessories collect respective data information and transmit the data information to the vehicle control unit through the CAN bus. The vehicle control unit is used for distributing energy to the high-voltage accessories according to the data information collected by the battery management system and the data information collected by the high-voltage accessories and the sequence of preset energy distribution priorities. The vehicle control unit can distribute energy to the high-voltage accessories according to the preset energy distribution priority sequence. When the temperature is low or the electric quantity of the battery is low, it can be avoided that the power used by the electric equipment exceeds the discharging capacity of the battery, over-discharging of the battery is prevented, the safety of the electric vehicle is improved, and the cruising ability of the electric vehicle is enhanced.

Description

technical field [0001] This application relates to the technical field of new energy vehicles, specifically an energy management system and method for high-voltage accessories of electric vehicles, and a smart vehicle. Background technique [0002] Pure electric vehicles use the power battery as the only energy storage device and power source. One of the biggest obstacles at present is the limited mileage; due to the limited energy stored in the power battery, in order to make the most efficient and reasonable use of energy as possible, To ensure the performance of the vehicle and improve the mileage, it is necessary to monitor and control the work of the high-voltage accessories of the pure electric vehicle, so that the energy can be reasonably distributed in the high-voltage system, so as to maximize the performance of the battery, motor and various high-voltage accessories, and ensure safety. On the premise of safety and reliability, improve battery life. Contents of th...
