Abstract

The invention provides an energy-saving type charging method, which is suitable for an energy-saving type fast charging device which is provided with a power supply transformation module and at least one fast charging type power accumulator, wherein the power supply transformation module obtains input electric power form an external power supply and transforms the input electric power into interior direct-current electric power to be output. The energy-saving type fast charging method comprises the steps of: checking whether an energy storing device is connected to outside; fast charging the fast charging type power accumulator by the interior direct-current electric power output by the power supply transformation module when the energy storing device is not detected; otherwise, fast charging the energy storing device by the interior direct-current electric power output by the power supply transformation module and the stored electric power of the fast charging type power accumulator.

Description

technical field [0001] The present invention relates to a charging device and method, in particular to an energy-saving fast charging device and method. Background technique [0002] Electric vehicles are driven by electric energy, replacing the use of fossil fuels, which can improve the dependence on oil resources and the deterioration of the global natural environment. It is a booming emerging industry. [0003] The energy storage device of the electric vehicle is supplemented by a charging device to supply electricity for the operation of the vehicle. see figure 1 , is a schematic diagram of the system architecture of the charging device in the prior art for charging the electric vehicle. As shown in the figure, the charging device 10 is used to charge the energy storage device 19 installed in the electric vehicle 18 . The charging device 10 includes a control module 11 , a power conversion module 12 and a power distribution module 13 . The control module 11 is the co...
