Abstract

Methods, systems, and devices that include improvements to determining properties of a battery are described. For example, a method may include measuring one or more properties of a battery by a device communicatively coupled to the battery; transmitting the measured one or more properties to a computing device located remotely from the battery; detecting, by the computing device and based on the measured one or more properties, one or more anomalous conditions within the battery; and transmitting, by the computing device, an indication of the one or more anomalous conditions.

Claims

1. A method comprising:

measuring one or more properties of a battery by a device communicatively coupled to the battery;

transmitting the measured one or more properties to a computing device located remotely from the battery;

detecting, by the computing device and based on the measured one or more properties, one or more anomalous conditions within the battery; and

transmitting, by the computing device, an indication of the one or more anomalous conditions.

2. The method of claim 1, wherein the measured one or more properties comprises a current flow to or from the battery.

3. The method of claim 1, wherein the measured one or more properties comprises a temperature of the battery.

4. The method of claim 1, further comprising:

transmitting, by the computing device, one or more updates to a charger configured to charge the battery, wherein the one or more updates are configured to change an operation of the charger during charging of the battery to address the one or more anomalous conditions within the battery.

5. The method of claim 4, wherein the measured one or more properties comprise a temperature of the battery, wherein the one or more anomalous conditions within the battery comprise the battery being above a predetermined threshold, and wherein the one or more updates transmitted to the charger are configured to reduce a maximum charging temperature of the battery from a first value to a second value lower than the first value.

6. The method of claim 1, further comprising generating, by the computing device, one or more predictions of properties of the battery.

7. The method of claim 6, further comprising:

performing one or more actions based on the generated one or more predictions of the properties of the battery.

8. The method of claim 7, wherein the performed one or more actions comprises transmitting the one or more predictions to a display device.

9. The method of claim 7, wherein the performed one or more actions comprises altering a term of a warranty covering the battery.

10. The method of claim 7, wherein the performed one or more actions comprises transmitting a recommendation to purchase a replacement of the battery.

11. The method of claim 1, wherein transmitting the measured one or more properties to the computing device located remotely from the battery comprises transmitting the measured one or more properties via a gateway.

12. An apparatus comprising:

a processor; and

memory storing computer-readable instructions that, when executed by the processor, cause the processor to perform operations comprising;

receiving one or more measured properties of a battery from a device communicatively coupled to the battery;

detecting, based on the one or more measured properties, one or more anomalous conditions within the battery; and

transmitting an indication of the one or more anomalous conditions.

13. The apparatus of claim 12, wherein the apparatus is remotely located from the device communicatively coupled to the battery.

14. The apparatus of claim 12, wherein the memory stores further computer-readable instructions that, when executed by the processor, cause the processor to perform further operations comprising:

transmitting one or more updates to a charger configured to charge the battery, wherein the one or more updates are configured to change an operation of the charger during charging of the battery to address the one or more anomalous conditions within the battery.

15. The apparatus of claim 14, wherein the measured one or more properties comprise a temperature of the battery, wherein the one or more anomalous conditions within the battery comprise the battery being above a predetermined threshold, and wherein the one or more updates transmitted to the charger are configured to reduce a maximum charging temperature of the battery from a first value to a second value lower than the first value.

16. The apparatus of claim 12, wherein the one or more measured properties are received via a gateway.

17. A battery monitoring system, comprising:

a battery;

a battery monitoring apparatus communicatively coupled to the battery; and

a computing device communicatively coupled to the battery monitoring apparatus;

wherein the computing device is configured to perform operations comprising;

receiving one or more measurements of characteristics of the battery;

determining one or more anomalous properties of the battery; and

transmitting one or more updates to a charger configured to charge the battery, wherein the one or more updates are configured to change an operation of the charger during charging of the battery to address the one or more anomalous properties of the battery.

18. The system of claim 17, wherein the one or more measurements of the battery comprise a measured temperature of the battery, wherein the one or more anomalous properties of the battery comprise the battery being above a predetermined threshold, and wherein the one or more updates transmitted to the charger are configured to reduce a maximum charging temperature from a first value to a second value lower than the first value.

19. The system of claim 17, wherein the one or more measurements of the battery comprise a time since a equalization charge of the battery was performed, wherein the one or more anomalous properties of the battery comprise the time since an equalization charge of the battery was performed exceeding a predetermined threshold, and wherein the one or more updates transmitted to the charger are configured to initiate an equalization charge of the battery in lieu of a non-equalization charge.

20. The system of claim 17, further comprising at least one remote device located remotely from the battery monitoring apparatus and from the computing device, wherein the computing device is configured to transmit one or more predictions of characteristics of the battery via a network.
