An electric vehicle charging electric quantity calculation system

Abstract

The invention relates to an electric vehicle charging electric quantity calculation system, comprising a monitoring server, a charging pile, a vehicle-mounted battery and a vehicle-mounted terminal. The charging pile is connected with a power supply and a monitoring server, and the monitoring server controls the charging pile to charge the vehicle-mounted battery. The vehicle-mounted terminal is connected with the vehicle-mounted battery and is communicatively connected with the monitoring server. The vehicle-mounted terminal collects the voltage or current of the vehicle-mounted battery in real time, calculates the charging electric quantity and transmits the information to the monitoring server. The vehicle-mounted terminal comprises a controller, a display module and a communication module. The controller is connected with the battery controller of the vehicle-mounted battery. The controller collects the voltage or current of the vehicle-mounted battery in real time and calculates the charging electric quantity. The display module is connected with the controller for displaying various information; The communication module is connected with the control, and is used for transmitting the charging power information to the monitoring server.

Description

technical field [0001] The invention belongs to the technical field of vehicle charging, in particular to a step and a calculation system for electric vehicle charging power. Background technique [0002] With the development of new energy electric vehicles, the application requirements of its customers are becoming more and more refined. Calculating the charging power of electric vehicles is an important data item. [0003] At present, the calculation of the charging power of electric vehicles on the market mostly uses the charging pile as the computing terminal, and the charging pile is connected to the background to obtain the charging power data of the vehicle. However, in the market, if the vehicle cannot report the vehicle information when calculating the charging power of the charging pile, or if the charging pile is used for charging, the charging pile cannot know which vehicle has been charged, and the charging power of the vehicle cannot be obtained from the chargi...
