MOBILE COOLING EQUIPMENT AND ITS POWER SUPPLY SYSTEM

A mobile cooling equipment and its power supply system are disclosed. The power supply system includes a power conversion unit, an isolation unit, a control unit, and a main power supply unit. The power conversion unit is to convert AC power input from an AC input terminal into DC power and output it from a DC output terminal. The isolation unit has an electrically isolated input terminal and multiple output terminals, and it is used to transmit DC power to these output terminals. The control unit is electrically connected to the isolation unit to control the transmission of DC power from the input terminal to the output terminals via electromagnetic coupling. The main power supply unit is electrically connected to a rechargeable battery and one of the output terminals of the isolation unit, and it outputs a boosted power supply to charge the rechargeable battery containing lithium metal.
