Abstract
Embodiments of the present disclosure provide methods, systems, and apparatuses related to managing a rechargeable battery in an enclosed lighting module. Other embodiments may be described and claimed.
Claims16
An apparatus comprising:
- a bulb-shaped light-passable body to define, at least in part, an enclosure;
- a light emitting diode (LED) disposed within the enclosure;
- a power supply interface configured to be coupled to a rechargeable battery in a manner such that the rechargeable battery, when so coupled, is disposed within the enclosure;
- and
- a controller disposed within the enclosure and coupled to the LED and the power supply interface, the controller configured to
- determine an electrical reflectivity of the rechargeable battery;
- determine an impedance of the rechargeable battery;
- and
- determine a state of charge and a predicted cycle life of the rechargeable battery based at least in part on the electrical reflectivity and impedance.

A method comprising:
- providing power to a light emitting diode disposed within an enclosure defined, at least in part by a bulb-shaped light-passable body, from a rechargeable battery also disposed within the enclosure;
- determining, with a controller disposed within the enclosure, an electrical reflectivity of the rechargeable battery;
- determining, with the controller, an impedance of the rechargeable battery;
- and
- determining a state of charge and a predicted cycle life of the rechargeable battery based at least in part on the determined electrical reflectivity and impedance.
