The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] Please refer to the appendix carefully. Figure 1-4 A mobile mounted energy storage power supply includes a converter unit and a battery unit. The converter unit includes a converter cell and a cable reel, and the battery unit includes a battery cell and a circuit breaker. The converter cell includes an inverter, a switch, and two sets of plugs. The battery unit is connected to the inverter via the plugs, and the inverter is electrically connected to the cable reel.

[0026] In use, a converter unit may be provided with multiple sets or a single set. When multiple sets are used, the DC side of the multiple sets of converter units is electrically connected, and the multiple sets of inverters are connected for communication via communication cables.

[0027] To ensure application safety, the battery unit also includes a controller, a liquid cooling device, an impact protection device, a charging gun interface, and a quick-connect plug. In actual use, the battery cells are arranged in multiple groups in series. The controller is connected to the battery cells by a temperature acquisition cable. The quick-connect plug is electrically connected to the circuit breaker. A fuse is connected between the battery cells and the impact protection device. The other end of the impact protection device is electrically connected to the circuit breaker.

[0028] like Figure 1 As shown, the AC / DC inverter converts direct current into alternating current. The inverter of the AC / DC inverter is connected to a circuit breaker. The DC side of the AC / DC inverter is connected in parallel with two quick-connect sockets through a circuit breaker. The quick-connect sockets are connected to the aforementioned battery cells. When one battery cell is depleted, a fully charged battery cell can be inserted through the other quick-connect socket, allowing the depleted battery cell to be taken out of operation and recharged, thus achieving uninterrupted power supply.

[0029] like Figure 2 As shown, the AC side of the converter unit is connected to the converter unit circuit breaker via a cable, and is also connected to a cable reel. The DC side of the converter unit is connected to other converter units via cables and circuit breakers. AC / DC communication cables are interconnected to enable information exchange between the inverters of each converter unit. In use, the battery cell is connected to the quick-connect socket of the converter unit, the battery cell provides DC power, and the converter unit inverts the DC power into AC power for application.

[0030] like Figure 3 As shown, the battery consists of multiple high-capacity cells connected in series. The voltage and temperature acquisition cables for each cell are connected to the controller. The battery outlet is connected to a fuse, and the other end of the fuse is connected to an anti-shock device, a switch, and a charging gun socket. The charging gun socket has a communication port between the controller and the charging station. The anti-shock device is controlled by the controller. The other end of the anti-shock device is connected to circuit breaker QF01 and a battery cooling device. The battery cooling device is also controlled by the controller. A quick-connect plug is connected to circuit breaker QF01.

[0031] Simultaneously, when a single battery cell is discharging, the controller uses the collected battery temperature to activate the battery cooling system to lower the battery temperature. At the same time, the anti-shock device activates, ensuring unidirectional current flow, allowing current to flow only from the battery to the quick-connect plug, preventing circulating current when another battery cell is connected.

[0032] The individual battery cells are charged through the charging gun interface, and the charger communicates with the controller to obtain battery information.
