Abstract:
1. A portable battery boost apparatus for charging a vehicle battery comprising: a boost battery that couples to the vehicle battery; a voltage monitoring module that monitors an amount of voltage in the vehicle battery and outputs a voltage reading indicative of an amount of voltage in the vehicle battery; a fault monitoring module that determines an existence of a fault condition based on at least one of the voltage reading and a current reading indicating an amount of current flowing from the boost battery to the vehicle battery; a load determining module that determines an existence of a load in the vehicle drawing power from the vehicle battery based on the voltage reading, wherein a fault condition exists when the voltage reading does not increase by at least a predetermined amount over a predetermined time period; and a boost battery cutoff module that decouples the boost battery from the vehicle battery upon determining the existence of the fault condition.
