Electricity quantity management and charging station matching system of electric automobile

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.
