  • a first input to receive an indication as to a temperature of a positive terminal from a first temperature probe;

    a second input to receive an indication as to a temperature of a negative terminal from a second temperature probe; and

    a monitor to take an action when a temperature differential that represents a difference in temperature between a temperature of the positive terminal and a temperature of the negative terminal at a single point in time exceeds a predetermined differential magnitude.
