The newer autos have alternators which happen to be "temperature compensated". This suggests they cost at unique voltages based on the temperature. A hot battery necessitates considerably less voltage to charge than a chilly battery, Therefore the temperature compensated alternators cost at a lower voltage when very hot than when chilly.
