Abstract

The invention discloses a feeding and charging method and a feeding and charging system of an electric automobile. The feeding and charging method comprises the following steps: at least one battery controller detects the voltage of a low-voltage battery; when the voltage of the low-voltage battery is smaller than a preset voltage threshold value, the battery controller sends a charging request toa vehicle control unit; the vehicle control unit acquires the current endurance mileage of the electric vehicle according to the received charging request; and if the current endurance mileage is greater than the preset endurance mileage threshold, the vehicle control unit controls a high-voltage loop of the electric vehicle to charge the low-voltage battery. According to the feeding and chargingmethod provided by the embodiment of the invention, the voltage of the low-voltage battery is detected through the at least one battery controller, so that the low-voltage battery is charged as required, and the situation that the vehicle cannot be used due to feeding of the low-voltage battery is avoided.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method for feeding and supplementing electricity for electric vehicles and a system for feeding and supplementing electricity for electric vehicles. Background technique [0002] With the accelerated integration of electronics, information, communication and other technologies with the automotive industry, cars are also developing in the direction of intelligence and networking, and vehicle configurations are becoming more and more diverse. Especially for new energy vehicles, intelligent networking is far greater than traditional fuel car. However, the growth of vehicle intelligent networking will inevitably increase the static power consumption of the vehicle, which will easily cause low-voltage power supply and make the vehicle unusable. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned tec...
