Claim Text:
1. A method for protecting against an energy source used to charge a battery, the method comprising the steps of: (a) receiving energy from the energy source at input terminals isolated from the battery by a switch; (b) determining if a voltage of the energy source at the input terminals is greater than a minimum source voltage threshold; (c) if the voltage of the energy source at the input terminals is not greater than the minimum source voltage threshold, opening the switch to disconnect the energy source from the battery and resetting a counter to zero; (d) if the voltage of the energy source at the input terminals is greater than the minimum source voltage threshold, incrementing the counter; (e) determining whether the counter has exceeded a counting threshold; (f) if the counter has not exceeded the counting threshold, repeating steps (b) through (e); and (g) if the counter has exceeded the counting threshold, closing the switch to connect the energy source to the battery.
