Abstract

A battery module system includes at least one cell and a battery module processor. The battery module processor may be configured to receive at least one cell signal associated with the at least one cell, wherein the at least one cell signal includes at least one of a temperature signal, a voltage signal, or a current signal. The battery module processor may be also configured to determine a status of the at least one cell based on the at least one cell signal. The battery module system may be configured to removably connect to a master/module interface, and to deliver power from the at least one cell to the master/module interface. The battery module system may be also configured to communicate, from the battery module processor, the status of the at least one cell to the master/module interface.

Claims

1. A system for providing power, wherein the system comprises:

a master/module interface configured to;

removably connect to a first battery module system,

receive power from at least one cell in the first battery module system,

receive, from a battery module processor in the first battery module system, a status of the at least one cell in the first battery module system,

removably connect to a second battery module system,

receive power from at least one cell in the second battery module system, and

receive, from a battery module processor in the second battery module system, a status of the at least one cell in the second battery module system; and

a battery master system connected to the master/module interface and including a battery master processor, wherein the battery master system is configured to;

receive, from the master/module interface, the power from the at least one cell in the first battery module system,

deliver, from the master/module interface, the status of the at least one cell in the first battery module system to the battery master processor,

receive, from the master/module interface, the power from the at least one cell in the second battery module system, and

deliver, from the master/module interface, the status of the at least one cell in the second battery module system to the battery master processor, wherein a chemistry of the at least one cell in the first battery module system is different from a chemistry of the at least one cell in the second battery module system.

2. The system of claim 1, wherein the battery master system is further configured to determine whether the first battery module system is compatible with the second battery module system.

3. The system of claim 1, wherein the battery master system is further configured to:

cause the power from the at least one cell in the first battery module system to be disconnected from the master/module interface; and

cause the power from the at least one cell in the second battery module system to be disconnected from the master/module interface.

4. The system of claim 1, wherein the battery master system is further configured to:

cause the power from the at least one cell in the first battery module system to be disconnected from the master/module interface through a disconnect in the first battery module system; and

cause the power from the at least one cell in the second battery module system to be disconnected from the master/module interface through a disconnect in the second battery module system.

5. The system of claim 1, wherein the battery master system is further configured to provide recharging power to the master/module interface for the at least one cell of the first battery module and the at least one cell of the second battery module.

6. The system of claim 1, wherein the status of the at least one cell of the first battery comprises at least one of a state of charge of the at least one cell of the first battery, a state of capacity of the at least one cell of the first battery, or a health of the at least one cell of the first battery.

7. A system for providing power, wherein the system comprises:

a master/module interface configured to;

removably connect to a first battery module system,

receive power from at least one cell in the first battery module system, and

receive, from a battery module processor in the first battery module system, a status of the at least one cell in the first battery module system; and

a battery master system connected to the master/module interface and including a battery master processor, wherein the battery master system is configured to;

receive, from the master/module interface, the power from the at least one cell in the first battery module system,

deliver, from the master/module interface, the status of the at least one cell in the first battery module system to the battery master processor, and

send a signal to the first battery module system to instruct the first battery module system to disconnect the at least one cell in the first battery module system from the master/module interface.

8. The system of claim 7, wherein:

the master/module interface is further configured to;

removably connect to a second battery module system,

receive power from at least one cell in the second battery module system, and

receive, from a battery module processor in the second battery module system, a status of the at least one cell in the second battery module system; and

the battery master system is further configured to;

receive, from the master/module interface, the power from the at least one cell in the second battery module system, and

deliver, from the master/module interface, the status of the at least one cell in the second battery module system to the battery master processor.

9. The system of claim 8, wherein a chemistry of the at least one cell in the first battery module system is different from a chemistry of the at least one cell in the second battery module system.

10. The system of claim 8, wherein the battery master system is further configured to determine whether the first battery module system is compatible with the second battery module system.

11. The system of claim 8, wherein the battery master system is further configured to cause the power from the at least one cell in the second battery module system to be disconnected from the master/module interface.

12. The system of claim 8, wherein the battery master system is further configured to:

cause the power from the at least one cell in the first battery module system to be disconnected from the master/module interface through a disconnect in the first battery module system; and

cause the power from the at least one cell in the second battery module system to be disconnected from the master/module interface through a disconnect in the second battery module system.

13. The system of claim 8, wherein the battery master system is further configured to provide recharging power to the master/module interface for the at least one cell of the first battery module and the at least one cell of the second battery module.

14. The system of claim 7, wherein the status of the at least one cell of the first battery comprises at least one of a state of charge of the at least one cell of the first battery, a state of capacity of the at least one cell of the first battery, or a health of the at least one cell of the first battery.
