An onboard charging system for an electric vehicle is configured to communicate with a power supply through exchange of control signals on a power supply line by modulating a charging current being supplied to the charging system. The charging system is capable of communicating fault and battery parameter data to the power supply, as well as a requested charging current used to regulate the power supply output. The power supply may convert high voltage AC power into a controllable DC output supplied directly to the electric vehicle, thereby providing a convenient means for the vehicle to initiate charging during operations. Connection between the electric vehicle and the power supply may be effected using an extendible and retractable electrical connection, such as a mechanical pantograph.

An electrical circuit for a vehicle includes at least one electrical contact device for an intermittently detachable electrical connection to a vehicle-external electrical network, a vehicle-internal electrical network and at least one detector device which determines if a connection exists between the contact device and the vehicle-external network. The circuit has at least one switching device which closes the electrical connection between the contact device and the vehicle-internal network depending on the connection determined between the contact device and the vehicle-external network. A method for making contact and/or breaking contact of a vehicle with a vehicle-external electrical network is also provided.

The present disclosure generally relates to a system and methods for managing and controlling emissions produced by a vehicle and/or powertrain which includes one or more power sources selected from a fuel cell, a fuel cell stack, a battery, and combinations thereof, a processor, one or more inputs, a controller, and one or more emission control devices.

The invention relates to systems and methods for charging a vehicle. A vehicle and charging station can be designed such that an electric or hybrid vehicle can operate in a fashion similar to a conventional vehicle by being opportunity charged throughout a known route.

An articulated vehicle having at least two vehicle parts which are connected to and articulated relative to each other is provided. The vehicle includes a front vehicle part and at least one rear vehicle part arranged behind the front vehicle part with respect to a longitudinal direction of the vehicle. The front vehicle part has a first drive unit including at least an electric motor and a first energy storage system; and at least one rear vehicle part has a drive unit including at least an electric motor and an energy storage system. Each rear vehicle part includes an individual electrical system that is galvanically isolated from the front vehicle part and from each other at least under normal driving conditions.

A vehicle charging station charges an energy accumulator in a battery-driven vehicle, namely an electric bus or hybrid vehicle, the vehicle being parked in a pre-defined parking position during the charging process. The charging station contains a base which is arranged in the vicinity of the pre-defined parking position and an articulated arm. One end of which is mounted in a revolute joint on the base and is rotary driven by a rotary drive and the other end is connected to a supply-contact device by a second revolute joint, such that the supply-contact device can be moved, by a pivoting movement of the articulated arm, between an idle position, in which the supply-contact device is positioned above the vehicle roof, and a working position, in which, for charging purposes, electrical contact is made between the supply-contact device and a receiving-contact device arranged in a static manner on the vehicle roof.

A moving body includes: a first body including at least one wheel, an electric motor and a first secondary battery; and a second body attachable to and detachable from the first body and including an electric power load and a second secondary battery. When the second body is mounted on the first body, at least one of the second secondary battery and the first secondary battery is allowed to be charged in a charging mode including at least one of a first charging mode and a second charging mode. In the first charging mode, the second secondary battery is charged using electric power output from the first secondary battery. In the second charging mode, the first secondary battery is charged using electric power output from the second secondary battery.

A vehicle charging system comprises a plurality of retractable conductor bars in a housing of a vehicle. The plurality of conductor bars includes a positive conductor bar and a negative conductor bar. Individual conductor bars of the plurality are electrically isolated from one another. The vehicle charging system further comprises a charging system having a receiver mounted on a support structure. The receiver comprises a plurality of electrical contact members in electrical communication with a power source. The receiver is configured to bring individual conductor bars of the plurality in contact with the electrical contact members for charging an energy storage device of the vehicle.

Systems and methods for charging an electric bus having a charging interface on its roof may include determining that an approaching bus is supposed to be charged at the charging station, lowering the charging head of the charging station to land on the roof of the bus, and moving the bus with the charge head on its roof to engage the charging head with the charging interface.
