US 9,520,746 B2 · Battery disconnect safeguard

Abstract

In embodiments, a mobile device includes a primary battery as a power source to power components of the mobile device, and includes a secondary battery as an additional power source to power the components of the mobile device. A sensor is implemented to detect moisture proximate a battery connection of the secondary battery, where the detected moisture indicates an impending secondary battery disconnect event due to the secondary battery shorting out. A battery controller is implemented to receive a sensor input of the detected moisture from the sensor. The battery controller can then switch from the secondary battery to the primary battery as the power source based on the detected moisture proximate the battery connection of the secondary battery.

Dependent claims

A system, comprising:

a primary battery configured as a power source to power components of a mobile device;
a secondary battery configured as an additional power source to power the components of the mobile device;
and
a battery controller configured to:
receive a sensor input of detected moisture proximate a battery connection of the secondary battery;
determine an impending secondary battery disconnect event due to the secondary battery shorting out as a result of exposure to the detected moisture;
determine that the primary battery is functional as the power source without the exposure to the detected moisture and without an impending primary battery disconnect event;
and
initiate a battery switch circuit switching from the secondary battery to the primary battery as the power source based on the sensor input of the detected moisture and the impending secondary battery disconnect event.
