Wireless communication system and control method

A wireless communication system, comprising:

• a control substrate, configured to generate a control message;
• and
• a plurality of energy storage devices, wherein each of the plurality of energy storage devices comprises:
• an energy storage element;
• and
• a node substrate, electrically connected to the energy storage element, wherein the node substrate comprises a first antenna circuit and a second antenna circuit, wherein the first antenna circuit comprises a first antenna unit and a second antenna unit disposed at opposite sides of the node substrate, and the second antenna circuit comprises a third antenna unit and a fourth antenna unit disposed at opposite sides of the node substrate, wherein the first antenna circuit is configured to receive the control message from the control substrate adjacent to the first antenna circuit or a first adjacent antenna circuit of a first adjacent node substrate of a first adjacent one of the plurality of energy storage devices, wherein the second antenna circuit is configured to transmit a reply message generated based on the control message to the control substrate adjacent to the second antenna circuit or a second adjacent antenna circuit of the first adjacent node substrate of the first adjacent one of the plurality of energy storage devices.
