Battery pack including sensing board and power storage system employing the same

A power storage system, comprising:

• a plurality of battery packs, each battery pack including:
• a plurality of rechargeable batteries,
• a sensing board, the sensing board being configured to process status information detected from each of the batteries of the respective battery pack, and
• a harness wire, the harness wire connecting the respective plurality of batteries and the sensing board of the respective battery pack for transmitting the status information to the sensing board of the respective battery pack;
• a battery management system (BMS) for controlling the status of the battery pack;
• and
• a power management system (PMS) for controlling overall power supply among the battery pack and peripheral devices, wherein:
• the peripheral devices include a power generating system for generating power and a commercial grid,
• the PMS is configured to receive power from the power generating system and the commercial grid, and
• the PMS is interposed between the power generating system and the commercial grid so as to control all power passing between the power generating system and the commercial grid.
