Charging terminal, equipment, system, station, energy storage pack and charging control method

Abstract

The invention discloses a charging terminal, equipment, a system, a station, an energy storage pack and a charging control method, and the charging terminal comprises a first charging circuit which is used for transmitting the electric energy outputted by a charger to a vehicle through a charging electrode, and charging the vehicle; the second charging circuit is used for transmitting the electric energy output by the energy storage pack to the vehicle through the charging electrode; a terminal controller and a communication circuit; wherein the terminal controller is respectively connected with the charger and the energy storage bag through the communication circuit, and is used for controlling the charger to output electric energy to supply power to the vehicle and / or the energy storage bag according to a communication signal; according to the invention, through the arrangement of the second charging circuit and the communication circuit in the charging terminal, the existing centralized integrated energy storage aiming at the charger is adjusted into the distributed energy storage aiming at the charging terminal, the energy storage function of the charging system can be realized by slightly transforming the existing charging terminal, the feasibility is high, the cost is low, and the popularization is easy.

Description

technical field [0001] The present invention relates to the technical field of charging, in particular to a charging terminal, equipment, system, station, energy storage pack and charging control method. Background technique [0002] At present, the charging system of electric vehicles often adopts such as figure 1 All-in-one charger shown, or as figure 2 The shown multi-terminal split charger charges an electric vehicle. [0003] In the prior art, in order to increase the energy storage function of the charging system, a centralized integrated energy storage is often used, such as image 3 As shown, the energy storage battery uses the AC / DC module (that is, the AC / DC conversion module) to obtain power from the grid for charging, and for discharging, the DC / DC module is used to charge the electric vehicle (EV) through the charger. However, the setting of this integrated energy storage requires the addition of AC / DC modules, DC / DC modules and corresponding charge and disc...
