An embodiment apparatus for an electric vehicle includes an indoor power outlet configured to receive power through one of a plurality of lines except for a single-phase alternating current (AC) charging line among three-phase AC input lines, a sensor configured to measure a required current of an electronic device connected to the indoor power outlet, and a controller configured to control a bidirectional on board charger of the electric vehicle based on the required current.

A vehicle and a method of immobilising a vehicle. The vehicle (100) includes a transport refrigeration unit (10), a power management system (20) for supplying power to the transport refrigeration unit (10), and a braking system (30). The power management system (20) includes an electric charging connector (26) and controller (24) configured to determine if a charging cable is engaged with the electric charging connector (26). If the controller (24) determines that a charging cable is engaged with the electric charging connector (26), the braking system (30) is configured to immobilise the vehicle (100).

A magnetic electrical plug interface for charging a transport refrigeration unit, TRU. The magnetic electrical plug interface includes a first electrical connector and a second electrical connector. The first electrical connector includes: a socket having a closed end and an open end; a first magnetic body including a first electrical contact, the first magnetic body is slidable in the socket; a resilient biasing element configured to bias the first magnetic body towards the closed end of the socket; and a second electrical contact fixed towards the open end of the socket. The second electrical connector includes: a second magnetic body including a third electrical contact. In an unplugged configuration in which the first electrical connector is disengaged from the second electrical connector, the resilient biasing element is configured to maintain a separation between the first electrical contact and the second electrical contact.

An electric power conversion system and a vehicle, to improve vehicle availability. The electric power conversion system may receive electric energy provided by a first power supply, and supply power to at least one load module. The system may include a first direct current to direct current conversion module and a second direct current to direct current conversion module. The first direct current to direct current conversion module is configured to perform voltage conversion processing on the electric energy and provide the electric energy to the at least one load module. The second direct current to direct current conversion module is configured to perform voltage conversion processing on the electric energy and provide the electric energy to the at least one load module.

An opening and closing device (2) has a flap (24) that is rotatably arranged on a hinged arm, and an actuator (72) to actuate the flap (24). The actuator (72) is coupled to a rotatable spindle (62) that is coupled to a flap actuating element (12). As the spindle (62) is rotated, a translational and rotational movement is performed to close and move the flap (24).
