Abstract

A battery system includes at least one battery unit, and a first battery management system that is operable to control the at least one battery unit. The first battery management system includes a first identification setup that is manually adjustable and is visible on an outside of the first battery management system, and the first battery management system is enabled to effect communication based on the first identification setup.

Claims

1. A battery system, comprising:

at least one battery unit; and

a first battery management system to control the at least one battery unit; and

a second battery management system to communicate with and control the first battery management system, wherein;

the first battery management system includes a first identification setup circuit that is manually adjustable to set a first identifier and is visible from outside of the first battery management system, the first battery management system to effect communication based on the first identifier, wherein the first identification setup circuit includes multiple manual switches to set a multiple-digit code corresponding to the first identifier, and

the second battery management system includes a second identification setup circuit that is manually adjustable, the second identification setup circuit including at least one manually configurable dip switch or rotary switch visible from outside of the second battery management system, wherein the second battery management system is not directly connected to the at least one battery unit or any other battery unit.

2. The battery system as claimed in claim 1, further comprising a control unit on a same substrate as the first identification setup circuit, the first identification setup circuit to communicate with the control unit.

3. The battery system as claimed in claim 1, wherein the first identification setup circuit is manually adjustable to set the first identifier, the first identifier corresponding to a communication identifier to effect communication via a network connected to the first battery management system.

4. The battery system as claimed in claim 1, wherein the multiple manual switches include at least one a manually configurable dip switch or rotary switch.

5. The battery system as claimed in claim 4, wherein the at least one manually configurable dip switch or rotary switch is visible from outside of the first battery management system.

6. The battery system as claimed in claim 5, wherein the multiple-digit code corresponds to a predetermined binary code to effect communication via a network connected to the first battery management system.

7. The battery system as claimed in claim 1, wherein:

the second battery management system is to communicate with the first battery management system via a controller area network, and

the first identification setup circuit is configured for controller area network communication and is manually adjustable without applying power via the battery system.

8. The battery system as claimed in claim 1, further comprising a control unit on a same substrate as the second identification setup circuit, the second identification setup circuit to communicate with the control unit.

9. The battery system as claimed in claim 1, wherein the first and second identification setup circuits are manually adjustable to represent different binary codes that effect communication via a network connected to the first and second battery management systems.

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

the second battery management system is to communicate with the first battery management system via a controller area network, and

the first battery management system is one of a plurality of first battery management systems that are tray management systems, the second battery management system being a master battery management system that is connected via bus lines to the first battery management systems.

11. An energy storage system having the battery system as claimed in claim 1.

12. An energy storage system that is connected to a power generation system, a grid, and a load, the energy storage system comprising:

a power conversion system; and

the battery system as claimed in claim 1, which is connected to the power conversion system.
