Energy storage robot and energy storage system

An energy storage system, comprising:

• at least one electric pile device, each of the at least one electric pile device having a first charging port defined thereon;
• and
• an energy storage robot comprising:
• a base provided with a battery therein and a moving device at a bottom of the base, the moving device being configured to drive the base to move relative to the ground;
• a support detachably connected to the base, the support being provided with a plurality of solar panels electrically connected to the battery, a light receiving area of the plurality of solar panels in a first state being smaller than a light receiving area of the plurality of solar panels in a second state;
• a second charging port movably connected to the base, a height of the second charging port relative to the base being adjustable;
• a plurality of sensors disposed at the base and/or the support and configured to detect a movement range and/or environmental information of the base;
• and
• a controller disposed at the at least one electric pile device and/or the energy storage robot, the controller being configured to control, in response to the base moving into a charging range of the at least one electric pile device, the second charging port to lift and lower to allow the second charging port to be connected to the first charging port.
