A control system controls power supply in a vehicle. The control system includes sub-power managers and an integrated power manager. The sub-power managers control respective output power of a plurality of subsystems that actualize functions of the vehicle. The integrated power manager performs integrated control of output power in the overall vehicle by exchanging information with the plurality of sub-power managers. The information that is exchanged between the plurality of sub-power managers and the integrated power manager includes information that enables calculation of a physical quantity that is expressed by at least either of a power dimension and an energy dimension.

During a normal DC bus mode, the first DC node and the second DC node are configured to operate a lower voltage level on the primary direct current bus. In contrast, during a boost DC mode, the first DC node and the second DC node configured to operate a higher voltage level, which is higher than the lower voltage level, on the primary direct current bus.

A vehicle-based high-voltage charging circuit is provided with an AC voltage terminal, at least two galvanically isolating DC-DC converters designed as step-up converters and a rectifier via which the DC-DC converters are connected to the AC voltage terminal, and a changeover switch. The charging circuit has a first and a second DC voltage terminal selectably connected to the first DC-DC converter via the changeover switch. The charging circuit has a third DC voltage terminal connected to the second DC-DC converter, wherein the charging circuit also has a controller which is set up, in a first mode, to drive the DC-DC converters according to a first target output voltage which is at least 750 V and at most 1000 V, and, in a second mode, to drive the DC-DC converters according to a second target output voltage which is at most 480 V or at most 450 V.

An electrified vehicle includes a mechatronic unit incorporating a motor that is a motive power source for driving front wheels and an electric power control device that supplies electricity of a battery to the motor. The electrified vehicle includes an integrated thermal unit that is an auxiliary. The mechatronic unit and the integrated thermal unit are installed between the front wheel on a vehicle right side and the front wheel on a vehicle left side, inside a wheel diameter of the front wheel as seen in a vehicle side view.
