Abstract

The invention relates to an electricity quantity management and charging station matching system of an electric automobile and belongs to the technical field of electric automobile charging. According to the technical scheme, the system comprises at least one electricity quantity management device (501) of the electric automobile and at least one charging station (502) matched with the electricity quantity management device (501). When monitoring that the electricity quantity of a vehicle-mounted power battery is smaller than a preset electricity quantity threshold value, a central processing unit controls first customer premise equipment (CPE) to obtain the position information of the charging station and information about whether the charging station is available or not, the current position of the electric automobile is obtained through a positioning unit, in this way, the central processing unit can control a display unit to display the most appropriate charging station or sequentially display a charging station list according to a recommending sequence, and a user can visually find the appropriate charging station. The problem that in the prior art, when the user needs to charge the vehicle-mounted power battery, the appropriate charging station of the electric automobile can not be found visually is solved, charging resources are reasonably utilized, and the development of the electric automobile industry is promoted.

Description

technical field [0001] The invention relates to a system for electric vehicle power management and matching charging stations, belonging to the technical field of electric vehicle charging. Background technique [0002] Due to the pressure of the environment and energy, the development of electric vehicles has received widespread attention at home and abroad. Electric vehicles mainly rely on vehicle-mounted power batteries to provide energy, and the vehicle-mounted power batteries of electric vehicles are supplied with energy through electric vehicle charging stations. In the prior art, the number of electric vehicle charging stations is limited, and the battery life of the vehicle-mounted power battery is relatively weak. At present, when users need to charge the vehicle power battery, they cannot intuitively find a suitable electric vehicle charging station, which is not convenient for users to use. Contents of the invention [0003] The purpose of the present inventio...
