Abstract
The energy-efficient fast charging method is applicable to an energy-efficient fast charging device having a power conversion module and at least a fast chargeable energy storage device. The power conversion module obtains and converts an input power from an external power source, and produces an internal DC power. The method contains the following steps. First, whether an external energy storage device is connected is detected. Then, if the presence of the external energy storage device is not detected, the internal fast chargeable energy storage device is charged by the internal DC power output from the power conversion module. Otherwise, the external energy storage device is charged by the internal DC power output from the power conversion module and the stored power of the fast chargeable energy storage device simultaneously.
