What happens when you connect a car charger?
As far as the car is concerned, all that happens when you connect the charger is that the voltage “supplied by the battery” goes up a few volts. They already have voltage regulators on any sensitive circuity to cope with that because the car’s own alternator/generator generates more voltage than the battery can.
Why do car chargers have voltage regulators?
They already have voltage regulators on any sensitive circuity to cope with that because the car’s own alternator/generator generates more voltage than the battery can.
