A power supply unit accommodates a main DC/DC converter and an AC charger (a charging circuit, a sub-DC/DC converter) in a housing. The main DC/DC converter and the sub-DC/DC converter are arranged in the same tier of the housing. The charging circuit is arranged in a tier different from that of the main DC/DC converter and the sub-DC/DC converter. The main DC/DC converter and the sub-DC/DC converter arranged in the same tier of the housing are controlled to operate in a mutually exclusive manner.

An embodiment method of controlling traveling of an electrified vehicle equipped with an electric motor as a power source includes determining whether it is possible to enter a variable control function. The variable control function includes a function of variably controlling a coasting torque level using a regenerative braking force. In response to a determination that it is not possible to enter the variable control function, a cause of an inability to enter the variable control function is determined and control is performed in a manner that corresponds to a determination that it is possible to enter the variable control function or the determination of the cause of the inability to enter the variable control function in response to the determination that it is not possible to enter the variable control function.

In a power supply system, a plurality of voltage converters have chargeable/dischargeable batteries connected to the respective primary sides and have respective secondary sides connected in parallel to each other. For each of the voltage converters, a voltage transformation rate is set such that the current measured by a primary side current measuring instrument is maintained within a first range between the discharge current maximum value of the batteries connected to the primary sides and the charge current maximum value of the batteries.

Systems, circuits, and methods are disclosed herein for charging (recharging) one or more batteries of an electric vehicle through an on-board charge shaping (or tuning) circuit. The charge shaping circuit may alter the charge signal received from a charging station and/or a regenerative charge signal from the vehicle motor based on one or more charge conditions at the battery. The shaped charge signal as controlled by the charge shaping circuit may improve one or more aspects of charging of the vehicle battery. The charge shaping circuit and/or a motor controller/inverter of the electric vehicle may include circuitry that is controllable to generate a shaped power signal in a similar manner as above, with or without the charge shaping circuit discussed above. In some implementations, one or more heat transfer systems may be included to transfer heat generated from the battery charging system to the battery.

A power control system includes a battery system and a DC-DC converter with first, second, third, and fourth power switches. A second terminal of the first power switch is connected to a first terminal of the second power switch. A second terminal of the third power switch is connected to a first terminal of the fourth power switch. A first inductor includes a first terminal connected to the second terminal of the first power switch and the first terminal of the second power switch and a second terminal connected to the second terminal of the third power switch and the first terminal of the fourth power switch. A first bypass switch is connected in parallel to the first power switch. A second bypass switch is connected in parallel to the third power switch.

An apparatus for handling notes of value can comprise a dispensing compartment for withdrawing the notes of value. The dispensing compartment is bounded on a first side by a depositing element and on a second side by a delimiting element. Furthermore, the apparatus comprises at least one first sensor unit for detecting an initialization position of the depositing element. The first sensor unit is designed to generate a first sensor signal and to transmit said first sensor signal to a control unit. The control unit is designed to take the first sensor signal as a basis for actuating a first drive unit such that the depositing element is moved a predetermined distance away from the delimiting element from the initialization position to a first supply position for supplying the notes of value.

A system for managing storage of electrical energy can include an electromagnetic machine and a controller. The electromagnetic machine can have a rotor and a stator. The rotor can be configured to be connected to a shaft. One of the rotor or the stator can have first windings and second windings.
