ENERGY-EFFICIENT FAST CHARGING DEVICE AND METHOD
First Claim
1. An energy-efficient fast charging method applicable to an energy-efficient fast charging device comprising a power conversion module and at least a fast chargeable energy storage device, said power conversion module obtaining and converting an input power from an external power source, and producing an internal DC power, said method comprising the following steps:
- detecting whether an external energy storage device is connected;
if the presence of said external energy storage device is not detected, charging said internal fast chargeable energy storage device by said internal DC power output from said power conversion module; and
if the presence of said external energy storage is detected, charging said external energy storage device by said internal DC power output from said power conversion module and the stored power of said fast chargeable energy storage device simultaneously.

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.

5. An energy-efficient fast charging device drawing an input power from an external power source and charging an external energy storage device connected to said energy-efficient fast charging device, comprising:
-
a power conversion module coupled to said external power source to obtain said input power and convert said input power into an internal DC power; at least a fast chargeable energy storage device coupled to said power conversion module; a distribution module coupled to said fast chargeable energy storage device and said power conversion module for connection to said external energy storage device; and a control module coupled to said fast chargeable energy storage device, said power conversion module, and said distribution module, said control module detecting the presence of said external energy storage device and controls the foregoing components; wherein, when the presence of said external energy storage device is not detected, said control module causes said internal fast chargeable energy storage device charged by said internal DC power output from said power conversion module; and
, if the presence of said external energy storage device is detected, said control module causes said external energy storage device charged by said internal DC power output from said power conversion module and the stored power of said fast chargeable energy storage device simultaneously.- View Dependent Claims (6, 7, 8, 9, 10)
