BATTERY SYSTEM FOR WEARABLE ELECTRONIC DEVICES

Resumen de: US20260079552A1

A power supply and management system used in handheld and wearable electronic devices. The system provides one or more batteries that are selectively removable from the device in a manner where the device is continuously powered and/or usable, including during recharging, replacement, or swapping of one or more of the batteries. The device either has multiple receptacles for multiple batteries, which allows batteries to be alternately removed and replaced while the remaining battery continues to provide power, or may include an on-board power storage apparatus that allows for short-term removal of all batteries while maintaining power and operation. In addition, power management of the system allows for selective use or depletion of multiple batteries to achieve uniform depletion, avoiding over-cycling of a single battery, transferring charge between batteries, and reserving charge in one battery until the other is fully depleted—all designed to maintain reliable power and operation.
