[0002] With the development and application of existing energy storage systems, miniaturization and centralized functions of energy storage systems have become a trend.

Professional and fast charging and after-sales maintenance services are necessary conditions for the market promotion of electric vehicles.

[0069] Furthermore, a plurality of air cooling modules are installed in the DC compartment;

[0070] The air cooling module is installed on the back panel of the DC compartment close to the DC / DC module and on the side panel of the DC compartment away from the power distribution compartment and close to the transformer module.

[0071] Furthermore, one air cooling module is installed on the back panel of the DC compartment at a position corresponding to each DC / DC module, and two air cooling modules are installed on the side panel of the DC compartment at positions corresponding to the transformer modules.

[0072] From the above description, it can be seen that the DC compartment in the cabinet adopts air cooling. Each layer of DC / DC modules is equipped with an air cooling module, and the transformer module on the bottom layer is equipped with two air cooling modules, which effectively ensures the heat dissipation effect of the DC compartment and avoids thermal runaway inside the DC compartment.

[0073] Furthermore, a fire protection box is installed in the power distribution compartment;

[0084] The DC busbar is also connected to the high-voltage relay through a wiring harness and then connected to the output end of the photovoltaic controller. The input end of the photovoltaic controller is connected to the external photovoltaic component through the photovoltaic circuit breaker.

[0085] From the above description, it can be seen that the external mains power is connected to the AC busbar by the AC circuit breaker, and then the transformer module transforms and outputs the AC power to the energy storage inverter, which is then inverted into DC power and transmitted to the main control box via the DC busbar. Finally, the main control box controls the transmission to each liquid-cooled box in the battery cluster to realize the energy storage function; at the same time, the DC busbar also transmits the DC power to the DC cabin through the DC circuit breaker and the transfer copper bar to power the DC control module and other equipment.
