Abstract

A charging station for electric vehicles is disclosed. The charging station includes a charge device and a terminal. The terminal is used for monitoring and recording the charging status of the charge device. The charging station can rapidly charge electric vehicles just like gas stations for engine powered vehicles.

Claims

1. A charging station for charging batteries of electrical vehicles comprising:

a charge device comprising;

at least one communication interface for communicating with the batteries to be charged; and

a plurality of charge units, each of the charge units further comprising;

a filter circuit for filtering noise interference from an alternating current (AC) power source and rectifying AC power into direct current (DC) power;

a power element forming signal on/off cycle for stabilizing output voltage or current;

an isolation and voltage-step-down module for matching the batteries to be charged and for preventing from interference when a charge process is performed by the charge units in parallel or series;

a feedback amplifier for feedback control; and

a controller receiving signals from the feedback amplifier and the communication interface for controlling on/off status of the power element; and

a terminal for monitoring and recording the charging status of the charge device.

2. The charging station of claim 1, wherein the batteries are installed in the electrical vehicles as a primary power.
