Abstract: An outdoor energy storage system cabinet and an outdoor energy storage system are provided. The cabinet includes a cabinet body, a water firefighting system, and a gas firefighting system. The water firefighting system includes a water firefighting pipe. The water firefighting pipe is arranged at a top part of an interior of the cabinet body and is provided with a water nozzle. The gas firefighting system includes a gas firefighting pipe. The gas firefighting pipe, like the water firefighting pipe, is arranged on the top part of an interior of the cabinet body. The gas firefighting pipe is configured to contain a firefighting fire extinguishing agent or transport the firefighting fire extinguishing agent. The gas firefighting pipe is provided with an air nozzle for ejecting firefighting gas generated by the firefighting fire extinguishing agent.

Abstract: A highly integrated mobile energy storage system is provided, which includes a container and battery racks. The battery racks are arranged in two rows along a length direction of the container, and the two rows of the battery racks are arranged back to back. For each of the two rows of battery racks, a maintenance door is arranged at a wall of the container close to the row of battery racks. In a case that a battery rack needs to be maintained, it is just required to open the maintenance door to maintain the battery rack. Since the two rows of battery racks are arranged back to back, no maintenance passage is required, thereby reducing a floor space along a width direction of the container, thus reducing the floor space of the system.

Abstract: A charging pile, and a device, system and method for testing a charging pile are provided. An inner side of a port of one of the gun bases is connected to an inner side of the same port of the other of the gun bases. An outer side of each port of each gun base connected to a port of a charging gun connected to the gun base, so that the two charging guns are connected. In addition, one of the two charging guns operates in the forward output state and serves as tested gun to be tested. The other of the two charging guns operates in the reverse conversion state and serves as a testing gun to test the tested gun. The gun base controller saves and exports the communication data on the communication bus between the two charging guns.

Abstract: A detection device, and a method for inspecting a relay, and a charging pile are provided. The detection device includes a detection module and an isolation output module, The detection module includes a first signal input terminal for connecting to an output side of a relay and a second signal input terminal for connecting to a neutral wire. A signal output terminal of the detection module is configured to connect to a control end of the isolation output module. The detection module is configured to output a control signal based on an on-off state of the relay. A signal output terminal of the isolation output module is configured to connect to a fault identification device. The isolation output module is configured to output a to detection signal with a duty cycle corresponding to the control signal, to inform the fault identification device to detect whether the relay is stuck.

Abstract: An energy storage container and a heat dissipation system for the same are provided. The heat dissipation system for the energy storage container includes a container body, and a battery module assembly and multiple air conditioning modules both located in the container body. In a length direction or a width direction of the container body, each of two side ends of the battery module assembly is provided with at least one air conditioning module. The heat dissipation system further includes an air supply duct and an air return duct, a partition plate is arranged in the air supply duct, to divide the air supply duct into a first air supply duct and a second air supply duct which are mutually independent. The above arrangement avoids increasing a height of the energy storage container, thereby effectively facilitating the transportation and installation of the energy storage container.
