Provided is a configuration in which, in an in-vehicle DC-DC converter, a limitation value of input power or output power can be determined according to the temperature of a power storage unit. In an in-vehicle DC-DC converter (1), a determination unit uses a scheme for determining whether or not input power of an input-side conductive path has reached an input power limitation value that is determined according to an input voltage of the input-side conductive path and a temperature range to which the temperature of an input-side power storage unit belongs, or a scheme for determining whether or not output power of an output-side conductive path has reached an output power limitation value that is determined according to an output voltage of the output-side conductive path and a temperature range to which the temperature of an output-side power storage unit belongs.

A vehicle battery charger and a vehicle battery charging system are described and illustrated, and can include a controller enabling a user to enter a time of day at which the vehicle battery charger or system begins and/or ends charging of the vehicle battery. The vehicle battery charger can be separate from the vehicle, can be at least partially integrated into the vehicle, can include a transmitter and/or a receiver capable of communication with a controller that is remote from the vehicle and vehicle charger, and can be controlled by a user or another party (e.g., a power utility) to control battery charging based upon a time of day, cost of power, or other factors.

A vehicle control system for moving a vehicle to a target location is disclosed. According to examples of the disclosure, a camera captures one or more images of a known object corresponding to the target location. An on-board computer having stored thereon information about the known object can process the one or more images to determine vehicle location with respect to the known object. The system can use the vehicle's determined location and a feedback controller to move the vehicle to the target location.

Provided are a charging device and a vehicle capable of reducing the amount of noise flowing into a quick-charging facility. The pair of charging lines connecting the quick-charging facility (20) to an onboard battery (30) are referred to as quick-charging lines, and each of these quick-charging lines is provided with a relay (16-1, 16-2). Each relay (16-1, 16-2) is used to switch the current flowing in the respective quick-charging line on and off, the current being switched on during quick-charge and being switched off during normal charging. Each quick-charging line has a Y-capacitor (17) connected thereto closer to a QC port (15) than the respective relay (16-1, 16-2).

An assembly includes a movable door assembly and a heating element. The movable door assembly is configured to be disposed on an exterior of a vehicle. The heating element is coupled to the movable door assembly, and is configured to receive energy from a battery disposed on the vehicle and to heat at least a portion of the movable door assembly.

A powertrain for electric and plug-in hybrid vehicle applications with integrated three-phase AC charging featuring buck-boost operation and optional vehicle-to-grid (V2G) capability, along with corresponding methods and machine instruction sets for switch control. The powertrain can include of a three-phase current source converter (CSC) front-end with an associated input filter, a polarity inversion module, and in an embodiment, a dual-inverter motor drive. The dual-inverter drive is the source of both the back emf and requisite DC inductance for the CSC. A compact design is thus provided as no additional magnetics are required and the on-board cooling system required for traction mode can be re-deployed for charging and V2G mode. The powertrain is mode shifted between charging and V2G mode through an optional polarity inversion module.

The present disclosure relates to a battery energy processing device and method and a vehicle. The battery energy processing device includes: a bridge arm converter, having a first bus terminal connected with a positive electrode of a battery and a second bus terminal connected with a negative electrode of the battery; a motor winding, having a first end connected with a midpoint of the bridge arm converter; an energy storage device, respectively connected with a second end of the motor winding and the second bus terminal; and a controller, configured to control, in a first preset state, the bridge arm converter to charge and discharge the battery, so as to realize heating of the battery. In this way, the charging and discharging of the battery can be controlled, and internal resistance of the battery causes the battery to generate a large amount of heat, which causes a temperature rise of the battery, thereby realizing the heating of the battery.

An access control system for electric vehicle charging is provided that includes an access device, a secure reservation interface, a reservation server and a smartphone application installed on the smartphone. The access device includes a short-range wireless communication module connected to a processor having control of an electric vehicle charger. The secure reservation interface receives a reservation request for a reservation at a given destination. The reservation server receives the reservation request for the destination, issues a reservation certificate, and transmits the reservation certificate from the reservation server to a smartphone. The smartphone application has access to a short range wireless communication setting corresponding to the access device. The access device receives the reservation certificate from the smartphone application based on use by the smartphone application of the short-range wireless communication setting. The processor activates the electric vehicle charger based on at least the receipt of the reservation certificate.

The present invention relates to a device for positioning a charger connector, in particular relative to a vehicle contra connector, comprising a suspension for a charging cable assembly, connected at one end to the charger connector, the suspension comprising a first suspension point, for clamping, at a point remote from the one end, the charging cable assembly in a predetermined orientation and position, which orientation and position together with the rigidity of the cable assembly and the gravity acting on the cable assembly define a preferred position and/or a preferred orientation of the one end; and a second suspension point, for engaging the charging cable assembly at the one end of the charger connector; Wherein the second suspension point comprises a manipulator for manipulating the position and/or the orientation of the charger connector relative to the fixed world, in a range around the preferred position and/or the preferred orientation of the one end of the cable assembly.
