A charging device including a first interface, by which the first connection between the charging device and a local network can be established; a second interface by which a second connection between the motor vehicle and the charging device can be established so that when the first connection is established, a data exchange between the local network and the motor vehicle is possible; at least one further interface by which a further connection between a further participant and the charging device can be established so that when the first connection is established, a data exchange between the local network and the further participant is possible; and a control device that is designed to request a predefined certificate from the vehicle and to establish the further connection without requesting and authenticating the predefined certificate.

Some implementations can include a supplemental regenerative braking system comprising a power take-off section to receive mechanical energy, and an electric clutch to engage the power take-off section and transfer mechanical energy from the power take-off section to an output of the electric clutch. The system can also include a roller stop assembly coupled to the output of the electric clutch and constructed to transfer mechanical energy from the output of the electric clutch, and a generator coupled to the roller stop assembly. The system can further include a flywheel coupled to the generator.

A system for sealed venting of a compartment includes a sealing member having a first body portion and a second body portion, an inner sealing member surface defining a central passage passing longitudinally from a first terminal end of the sealing member to a second terminal end of the sealing member, an outer sealing member surface defining an outer circumference of the sealing member, a sealing flange extending radially outward from the outer sealing member surface, and a channel including at least one stop surface. A securing member having a securing flange engages with the second body portion. The channel engages with the aperture defined in the body when the sealing member is inserted into and rotated in the aperture and the sealing flange and the securing flange seal the sealing member to the inner and outer surfaces of the body.

A system and a method for reducing the acceleration shock of an electric motor vehicle are provided. A backlash torque range is determined based on a coast down value indicating the motor torque for maintaining a vehicle speed. A slope of the motor torque that falls within a backlash torque range is reduced and corrected, considering that the motor torque for causing backlash is changed as the motor speed changes, thereby reducing the shock due to the backlash at the acceleration (start-up) of a vehicle.

A communication method and system for supporting a high data transmission rate is provided. The method and system fuses 5G communication systems with IoT technology to transmit data at a higher rate than 4G systems. The communication method and system is applied to intelligent services, based on 5G communication technology and IoT related technology, for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security, safety-related services, etc. A method and apparatus is provided that increases the amount of MBMS, according to the demand increase in MBMS, using an MBMS dedicated carrier, in a mobile communication system.

An off-board battery charger for a vehicle may include a high-voltage connector having first, second and power supply connector ports. The first connector port connects to a vehicle controller via a first cable. The second connector port connects to a vehicle battery via a second cable. And, the power supply connector port is electrically connected with the second port and receives power via a power supply cable from a separate and external power supply.

The fuel cell vehicle includes a fuel cell placed in a front room, an air compressor placed below the fuel cell in the front room to supply the fuel cell with cathode gas, and a refrigerant supply pump placed below the fuel cell in the front room to supply the fuel cell with a refrigerant. The refrigerant supply pump is placed forward of the air compressor.

A high voltage diagnostic connector includes a housing holding a positive terminal, a negative terminal and a ground terminal with a cover removably coupled to the housing. An HVIL assembly is in the housing having a HVIL contacts and an HVIL shunt. An HVIL switch is held by the housing including a shunt actuator operably coupled to the HVIL shunt to position the HVIL shunt in an un-shunted position to open an HVIL circuit when in the primary position and in a shunted position to close the HVIL circuit when in the secondary position. The shunt actuator is movable between the primary position and the secondary position when testing the positive terminal, the negative terminal and the ground terminal with the testing device during diagnostic testing of the high voltage diagnostic connector.
