The pictured part, which is necessary to keep the amount of energy in the car steady, goes by what name?

Modern voltage regulator designs use transistors to regulate the current in a vehicle. They generally force an alternator to maintain a voltage between 13.5 and 14.5 volts to recharge the battery safely while protecting the car's electrical circuits.
