Embodiment 1

[0036] Please refer to figure 1 and Figure 5 , the energy storage free linkage DC charging system provided by Embodiment 1 of the present invention is used to charge electric vehicles, and includes a plurality of charging piles 100, each of which includes at least one dual-input charging module 1, each of which The dual-input charging module 1 is connected to at least one charging gun 2, and each of the dual-input charging modules 1 in each of the charging piles 100 is connected to the AC grid 200 and the energy storage battery 300 at the same time, and the AC grid 200 and the / or the energy storage battery 300 transmits electric energy to the corresponding charging gun 2 through each of the dual-input charging modules 1 to charge the electric vehicle; that is, each of the charging piles 100 has Two power supply modes, respectively supplying power to the AC grid 200 or the energy storage battery 300; the energy storage battery 300 is preferably an energy storage battery with...

Embodiment 2

[0070] The difference between Embodiment 2 and Embodiment 1 is that each of the charging piles 100 and each of the dual-input charging modules 1 in the energy storage free linkage DC charging system provided by Embodiment 2 are respectively connected to a The energy storage battery 300, that is to say, each charging pile 100 in the energy storage free linkage DC charging system provided in the second embodiment has an independent power supply. This solution can store more energy and can be used for More electric vehicle charging, usually suitable for medium and large charging stations.

[0071] In summary, the energy storage free linkage DC charging system provided by the present invention controls all the first switching switches 3, all the second switching switches 4 and All dual-input charging modules 1 realize the free switching of multi-pile charging, and can rationally allocate the charging power output of each charging pile according to the actual charging power demand ...

Abstract

The invention discloses an energy storing type free linkage direct current charging system which comprises multiple charging piles. Each charging pile at least comprises a double-input charging module. Each double-input charging module is at least connected with one charging gun. The double-input charging module in each charging pile is connected with an alternating current power grid and an energy storing battery at the same time. A first fling-cut switch is connected between output ends of the double-input charging modules. A second fling-cut switch is connected between each double-input charging module and each charging gun connected with the double-input charging module in a corresponding manner. The charging system further comprises a general control unit. All the first fling-cut switches, all the second fling-cut switches and all the double-input charging modules are electrically connected with the general control unit. According to the system, all the fling-cut switches and allthe double-input charging modules are controlled in a linkage manner through the general control unit, output of charging power of all the charging piles are reasonably deployed, and the charging efficiency of the charging system is improved beneficially.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an energy storage type free linkage DC charging system. Background technique [0002] The electric vehicle charging system in the prior art usually connects to the distribution network to provide charging power for the electric vehicle. This kind of power supply mode is single. Electric car charging. [0003] In order to achieve the goal of energy reduction and emission reduction to the greatest extent, the electric vehicle charging system in the prior art usually has the function of multiple charging piles linked to charge the electric vehicle. For example, the charging system allocates the same charging power to each charging pile. When one charging pile cannot provide the charging power required by the electric vehicle, other charging piles can provide part of the charging power to the electric vehicle at the same time. Efficiency is a problem that needs to...
