The first part except for the rest of the four parts are the power load, mechanical load, climate load and chemical load, in addition, the power system can be applied to 12 volts and 24 volts (passenger) (commercial vehicle) two, but due to space this paper will use restrictions, only for a larger proportion of passenger cars (Passenger Car) 12 volt system respectively according to four load requirements descr iption.)
