Examples described herein provide a computer-implemented method that includes monitoring, using a microcontroller, an electric circuit of a vehicle, the electric comprising a battery source and a load. The battery source supplies electric power to the load. The method further includes detecting, using the microcontroller, a high current event in the electric circuit by comparing a current level of a current flowing through the electric circuit to a time-based current threshold. The method further includes responsive to detecting the high current event, controlling a gate driver to cause a switch of an electronically resettable fuse to open the electric circuit to stop the flow of the current through the electric circuit.

An electronic device according to various embodiments may include: a battery, a switch coupling the battery to a main board on which components of the electronic device are disposed, a power management module comprising power management circuitry including a function of powering on the electronic device at a power-on time set to power on the electronic device that is in a power-off state of the electronic device, and a processor. The processor may be configured to: upon identification of a power-off request for the electronic device, set the power-on time and power off the electronic device, based on the electronic device being powered on upon identification of the power-on time, compare a power-off period of the electronic device with a threshold period, and based on the power-off period of the electronic device being longer than a threshold period, decouple the battery from the main board by opening the switch.
