Abstract
Embodiments of the present disclosure provide systems and methods for extending the operational life of battery-operated devices, such as an Internet-of-Things device, by adapting the device to monitor its' own battery condition, and in response to detecting conditions indicating passivation of the battery, execute a refresh cycle to restore battery capacity. In this way, the battery can be refreshed by running a series of oxidation ‘burn off’ cycles periodically during the device's lifetime.
Claims20
A method for maintaining a battery in an Internet-of-Things (IoT) device, the method comprising:
- determining, by a processor of the IoT device, whether to perform battery maintenance;
- in response to determining to perform battery maintenance, performing, by the processor of the IoT device, a pre-check process on the battery of the IoT device;
- determining, by the processor of the IoT device, based on results of performing the pre-check process, whether battery passivation is occurring on the battery of the IoT device;
- and
- in response to determining battery passivation is occurring on the IoT device, performing, by the processor of the IoT device, a de-passivation process on the battery of the IoT device.
An Internet-of-Things (IoT) device comprising:
- a processor;
- and
- a memory coupled with and readable by the processor and storing therein a set of instructions which, when executed by the processor, causes the processor to:
- determining whether to perform battery maintenance;
- in response to determining to perform battery maintenance, performing a pre-check process on the battery of the IoT device;
- determining based on results of performing the pre-check process, whether battery passivation is occurring on the battery of the IoT device;
- and
- in response to determining battery passivation is occurring on the IoT device, performing a de-passivation process on the battery of the IoT device.
