What.. alternates by them to recharge the battery? How is it recharging? In a gas car? While its off? I feel like an idiot!
In: Engineering
DC generators output based on speed and at idle don’t produce enough voltage to charge a battery. AC voltage can be increased with a transformer and then rectified to a rippled DC with just a set of diodes. So the alternator can charge the battery at any engine speed.
