[0050] The high-voltage AC box and the high-voltage DC box are used for charging and discharging the Pack battery. The energy storage PCS is used to control the high-voltage AC box and the high-voltage DC box to charge and discharge the Pack battery, and provide functions such as power coupling with other electrical energy storage devices and grid connection.

[0051] The equipment bracket 10 divides the equipment compartment 9 into four equipment storage spaces. The water-cooling and heat dissipation equipment and the energy storage PCS are located on the left side of the equipment compartment 9 (close to the battery compartment 7) and arranged up and down.
