ELECTRICAL ENERGY SYSTEM FOR A VEHICLE, ELECTRICAL ENERGY CONTROL DEVICE FOR A VEHICLE, METHOD FOR ELECTRIC ENERGY CONTROL OF A VEHICLE, AND A PROGRAM INCLUDING COMPUTER-READABLE RECORDING MEDIUM

摘要

An electric power system for a vehicle includes a waste heat recovery device, a low voltage system, a high voltage system, a first wireline, a second wireline, and a DC / DC converter. The waste heat recovery device includes an electric generator configured to generate electrical energy based on heat dissipated from a heating element. The low voltage system contains a low voltage secondary battery. The high voltage system includes a high voltage secondary battery that outputs a higher voltage than the low voltage secondary battery. The first wire line connects the power generator to the low voltage system. The second wireline connects the first wireline to the high voltage system. The DC / DC converter is arranged on the second wire line and raises and lowers a voltage supplied to the DC / DC converter.
