1. A method comprising:
monitoring, using a microcontroller, an electric circuit of a vehicle, the electric circuit comprising a battery source and a load, wherein the battery source supplies electric power to the load;
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;
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; and
updating the time-based current threshold based at least in part on data collected form other vehicles.
