Abstract

The invention discloses an electric vehicle DC charger control system comprising a charger, a server terminal and an APP. The charger comprises a signal transceiver and an information processing unit.The APP comprises a top up unit, a code scanning unit and a code input unit. The charger is in bidirectional connection with the server terminal through a wireless signal. The APP is also in bidirectional connection with the server terminal through a wireless signal. The signal transceiver is in bidirectional connection with the information processing unit. The charger is connected to a battery voltage sensing unit through a wire. The battery voltage sensing unit is connected to an output voltage adjusting and detecting unit through a wire. The output voltage adjusting and detecting unit is connected to a charging IC. The electric vehicle DC charger control system is perfect in functions and convenient to use, can inform a user of a battery charging state in real time, can protect batteryovercharge safety, and has good practicability.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a control system for a DC charger of an electric vehicle. Background technique [0002] The charger adopts high-frequency power supply technology and uses advanced intelligent dynamic adjustment charging technology. It adopts constant current / constant voltage / small constant current intelligent three-stage charging method, which has the characteristics of high charging efficiency, simple operation, light weight and small size. [0003] The existing chargers are not smart enough when charging, and the user cannot know the charging situation in real time when charging, so that he cannot accurately know when the charging is completed, which wastes the charging time and is inconvenient in practical application. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings that the existing charger cannot inform the electric v...
