A transmission mechanism is provided with an output gear drivingly coupled to at least one of a pair of output members and placed coaxially with the pair of output members. A direction in which a rotating electrical machine and an inverter device are arranged side by side in an axial view is defined as a first direction. A direction perpendicular to both an axial direction and the first direction is defined as a second direction. A first output member that is one of the pair of output members is placed between the rotating electrical machine and the inverter device in the first direction, at a position in the second direction where both the rotating electrical machine and the inverter device are placed. The output gear is placed in such a manner as to overlap each of the rotating electrical machine and the inverter device in the axial view.

An onboard DC charger for an electric vehicle, wherein the electric vehicle includes an electric machine and a power conversion device that is a drive circuit for the electric machine and a charging circuit for the on-board battery. The one or more electric machines of the vehicle are mounted to the body for providing locomotive energy, wherein the or each machine has a stator, a rotor mounted to the stator for rotation, and one or more windings; and a controller for operating in a first state and a second state wherein, in the first state, the controller allows current to be drawn from the DC energy source for energising at least one of the one or more windings such that the electric machine provides the locomotive energy and, in the second state, the controller controls the position of the rotor relative to the stator and allows at least one of the one or more windings to be energised to provide a charging current to the DC energy source.

An example operation includes one or more of initiating, by a transport, a request to provide a first portion of stored energy to a charging station, determining, by the charging station, an actual amount of energy needed by the transport, wherein the determining is based on a first destination of the transport and on data received by the charging station based on a route associated with the first destination, wherein the actual amount of energy is not the same amount as the first portion of stored energy, and depositing, by the transport, the actual amount of energy in the charging station.

A management server is configured to perform a process including: setting a basic fee of a first monthly fee when a utilization manner is battery lease; setting discount rates based on the weight, capacity, manufacturer, degree of initial deterioration, amount of power consumption, number of times of performing quick electric charging, utilization region, and utilization period of the battery; determining the first monthly fee; setting a basic fee of a second monthly fee when the utilization manner is vehicle lease; setting discount rates based on the weight of the battery, a utilization region of the vehicle, and a utilization period; determining the second monthly fee; and determining a total monthly fee.

A battery system includes a rechargeable energy storage system and a battery controller. The rechargeable energy storage system has a rapid charging mode and a discharging mode. The battery controller is electrically coupled to the rechargeable energy storage system and is configured to store multiple charging tables that contain multiple charge current limit entries, where each charging table corresponds to a unique one of multiple initial state-of-charge values, determine a starting state-of-charge value of the rechargeable energy storage system in response to entering the rapid charging mode, select up to two charging tables in response to the starting state-of-charge value of the rechargeable energy storage system being adjacent to up to two of the initial state-of-charge values, and control a charging current provided to the rechargeable energy storage system based on the charge current limit entries in the up to two charging tables as selected.

A multi-charger, serially operated electrical vehicle (EV) charging system, contains a Power Control System (PCS) providing DC power. A plurality of EV chargers is serially power-connected to each other, wherein the first EV charger is connected to the PCS. There are sets of relays in at least the first EV charger, wherein a first set of the set of relays, when activated, is configured to supply power to a respective charging cable of the EV charger, and a second set of the set of relays, when activated, is configured to supply power to a next-serially connected EV charger. The sets of relays contain auxiliary contacts providing relay status information. A hardware logic prevents the first and second sets of relays from simultaneously being activated, allowing only one EV charger of the plurality of EV chargers to charge at a time.

A multimodal converter for use in electric vehicle charging stations for interfacing between at least one AC source and two DC sources (including the electric vehicle with onboard DC traction accumulator). The multimodal converter may also be applicable to other uses with a multitude of energy sources. For example, where the multimodal converter AC interface is for an electric motor, such as in a plug-in electric vehicle, an electric power tool, an electric water pump, a wind turbine, or the like, or interfacing with any DC sources such as an electrical battery apparatus, a solar panel array, a DC generator, or the like, whether for private, commercial or other use.

The ground power supplying apparatus includes a communication device for directly communicating with the vehicle by short range wireless communication with a communication distance of less than 10 meters, and a controller configured to control power transmission by the ground power supplying apparatus. If the communication device receives vehicle identification information from a second vehicle during supply of power from the ground supplying apparatus to a first vehicle, the controller is configured to stop supply of power to the first vehicle when the communication device receives the vehicle identification information from the second vehicle.

A ground power supplying apparatus provided with a power transmission apparatus having a resonance circuit and transmitting power to the vehicle and a control device shifting a state of the ground power supplying apparatus to a standby state when a predetermined suspension condition stands if the state of the ground power supplying apparatus is a main power transmission state or a power transmission active state and shifting a state of the ground power supplying apparatus to the power transmission active state when the suspension condition no longer stands if the state of the ground power supplying apparatus is the standby state.
