Abstract

A battery pack includes a battery unit including rechargeable batteries, a sensing board, the sensing board configured to process status information detected from the batteries, and a harness wire, the harness wire connecting the batteries and the sensing board so that the status information can be transmitted to the sensing board.

Claims

1. 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.

2. The power storage system as claimed in claim 1, wherein the battery pack has integrated therein a battery unit that includes the respective batteries, the sensing board, and the harness wire.

3. The power storage system as claimed in claim 2, wherein the sensing board is configured to perform analog/digital conversion of the status information and transmit the converted digital signal to the BMS.

4. The power storage system as claimed in claim 3, wherein the BMS is configured to transmit the status information to the PMS, and to control charging and discharging of the battery unit.

5. The power storage system as claimed in claim 2, wherein the sensing board is configured to process status information that includes information regarding one or more of voltage, current, and temperature of the battery pack.

6. The power storage system as claimed in claim 5, wherein the sensing board is configured to process status information that includes information regarding one or more of voltage, current, and temperature of respective batteries of the battery pack.

7. The power storage system as claimed in claim 1, wherein the batteries include nickel-cadmium batteries, lead acid batteries, nickel metal hydride batteries, lithium ion batteries, lithium polymer batteries, or a combination thereof.

8. The power storage system as claimed in claim 1, wherein the power generating system includes one or more of a photovoltaic system, a wind power generating system, and a tidal power generating system.

9. The power storage system as claimed in claim 1, wherein the commercial grid includes power plants, substations, and power lines.

10. The power storage system as claimed in claim 1, wherein:

the peripheral devices include a load for consuming power provided by the PMS, and

the PMS is configured to provide power to the load.

11. The power storage system as claimed in claim 10, wherein the load includes a household or a commercial facility.
