Abstract

A battery is provided that includes a battery monitoring system integrated within the battery. The battery monitoring system includes a diagnostic system configured to monitor or store at least one parameter of the battery. Additionally, the battery monitoring system also includes a receiver communicatively coupled to the diagnostic system. Furthermore, the battery monitoring system includes a transmitter communicatively coupled to the diagnostic system and configured to activate upon receipt of a first wireless signal by the receiver and to transmit a second wireless signal indicative of the at least one parameter of the battery.

Claims

1. A battery, comprising:

a battery monitoring system integrated within the battery, wherein the battery monitoring system comprises;

a diagnostic system configured to monitor or store at least one parameter of the battery;

a receiver communicatively coupled to the diagnostic system; and

a transmitter communicatively coupled to the diagnostic system, and configured to activate upon receipt of a first wireless signal by the receiver and to transmit a second wireless signal indicative of the at least one parameter of the battery;

wherein the at least one parameter of the battery comprises a time, a voltage, a temperature, or a current; and

wherein the time corresponds to a time after manufacture of the battery, and the diagnostic system is configured to activate the diagnostic system after the time passes a threshold value.

2. The battery of claim 1, wherein the receiver is configured to receive the first wireless signal from a transmitter remote from a system that encloses the battery.

3. The battery of claim 1, wherein the first signal comprises an optical light signal.

4. The battery of claim 1, wherein the first signal comprises a radio frequency signal.

5. The battery of claim 1, wherein the transmitter is configured to transmit the second wireless signal to a receiver remote from a system that encloses the battery.

6. The battery of claim 1, wherein the second wireless signal comprises a radio frequency signal.

7. The battery of claim 1, wherein the second wireless signal comprises a visual signal or an audio signal.

8. The battery of claim 1, wherein the battery monitoring system comprises a transceiver having the receiver and the transmitter.

9. The battery of claim 1, wherein the receiver is configured to receive a third wireless signal, wherein the battery monitoring system is configured to activate a standby mode when the receiver receives the third wireless signal.

10. The battery of claim 9, wherein the battery monitoring system is configured to deactivate the standby mode upon detection of a voltage change in the battery, current draw on the battery above a current threshold, an lapse of time greater than a time threshold, a fourth wireless signal received by the receiver, or some combination thereof.

12. The method of claim 9, wherein the at least one parameter of the battery comprises a battery voltage, a battery temperature, and a battery current.

13. The method of claim 9, wherein the second signal comprises a radio frequency signal.

14. The method of claim 9, wherein the at least one parameter of the battery comprises an end of life of the battery.

15. The method of claim 9, wherein the first or second signal comprises an optical light signal.

16. The method of claim 9, wherein the first signal is transmitted by a device remote from the battery.

11. A method for monitoring a battery, comprising:

wirelessly receiving a first signal via a diagnostic system integrated within the battery, wherein the first signal is indicative of activation of a transmitter of the diagnostic system;

monitoring at least one parameter of the battery via the diagnostic system;

monitoring a time after manufacture of the battery and activating the transmitter of the diagnostic system upon a duration of time after the manufacture of the battery; and

wirelessly transmitting a second signal indicative of the at least one parameter of the battery upon receipt of the first signal.

17. A battery system, comprising:

a battery;

a communication device remote from the battery and configured to receive a wireless signal

a battery monitoring system integrated within the battery, comprising;

a diagnostic system configured to monitor at least one parameter of the battery, wherein the diagnostic system is configured to activate upon a duration of time after manufacture; and

a transmitter communicatively coupled to the diagnostic system, and configured to transmit the wireless signal indicative of the at least one parameter of the battery.

18. The battery system of claim 17, wherein the wireless signal is also indicative of the at least one parameter, and the at least one parameter comprises at least one of battery voltage, battery current, and battery temperature.
