Abstract
A jump start protection circuit having a normally open switch and a resistor positioned in parallel intermediate to a battery and a jump start post. A controller manipulates the switch between an open position and closed position, the closed position connects the jump start post to the battery and the open position disconnects the jump start post from the battery. The controller measures voltages at the battery and jump start post and is capable of receiving one or more additional inputs. The controller closes the switch when acceptable jump start conditions are detected. The controller can open the switch or maintain the switch in an open position. The jump start circuit provides protection against attempts to charge a battery with incorrect polarity connections and attempts to charge a battery from a potentially hazardous higher voltage power source.
