A door lock assembly includes a housing having a hollow structure, a lifting shaft provided inside the housing, a driving spring, and a buffering device. A top end of the lifting shaft is configured for assembling a refueling or charging port flap, the lifting shaft being slidably engaged with the housing along a first portion and threadably engaged with the housing along a second portion. One end of the driving spring is fixed and the other end abuts against the lifting shaft for driving the lifting shaft to move relative to the housing. The buffering device provides a buffering function in the when the lifting shaft is threadably engaged with the housing.

A power supply device for an electric work vehicle, including: a battery by which an electric work vehicle is drivable; a first connection unit for an internal inverter configured to convert DC power from the battery into AC power, and output the AC power to an internal electric device installed in the electric work vehicle; a second connection unit for an external inverter configured to convert DC power from the battery into AC power, and output the AC power to an external electric device; and a battery control unit connected to the first connection unit and the second connection unit, and configured to control charging of, and power supply from, the battery, wherein the battery control unit is configured to communicate with the external inverter side via the second connection unit to perform authentication regarding whether or not power supply to the external inverter is permitted.

Systems and methods for charging electric vehicles that define a charging schedule for an electric vehicle based on one or more charging preferences of an operator of the vehicle and based on at least one current value of a dynamic attribute of an electric charge provider. Such systems and methods may include a graphical user interface adapted to display a unitary vehicle charge indicator element having (i) a first portion indicative of an amount of charge residing in a battery of the electric vehicle, (ii) a second portion indicative of an uncharged capacity of the battery of the electric vehicle, and (iii) a third portion comprising a slider by which an amount of charge may be specified.

A vehicle includes a first power receiving port, a first lid provided at the first power receiving port, a first lid lock device configured to switch the first lid between locked and unlocked states, and a controller configured to control the first lid lock device to a locked or unlocked state. When an entry door of the vehicle is locked while the first lid is open, the controller is configured to set the first lid lock device to the unlocked state until the first external charging is started, set the first lid lock device to the locked state when the first external charging is started, and set the first lid lock device to the unlocked state when the first external charging completes.

A locking device for an energy storage device of a motor vehicle, includes a locking element, which is adjustable based on a control signal, by an adjusting device between a locking position, in which the locking element engages with a latch receptacle, and a release position, in which the locking element is out of engagement with the latch receptacle. The adjusting device has an adjusting element made of a shape memory alloy. The shape change enables the locking element to be adjustable between the locking position and the release position.

An electric vehicle charging connector, including a set of pins, a sensor, and a controller. The set of pins may include a DC pin, wherein the DC pin is configured to supply DC power to a charging port, wherein the charging port comprises a locking mechanism. The sensor can detect power flow from the pins to the charging port. The controller is communicatively connected to the sensor and configured to receive a signal from the sensor and send a locking signal to a locking mechanism. The locking mechanism comprises an engaged state wherein the charging connector is mechanically coupled to the charging port and a disengaged state wherein the charging connector is mechanically uncoupled form the charging port, wherein the locking mechanism is configured to receive a locking signal from the controller of the charging connector and enter the engaged state.

Systems and methods for charging electric vehicles and for quantitative and qualitative load balancing of electrical demand are provided.

An electric vehicle charging station network server that manages a plurality of charging stations receives subscriber notification message preferences for a subscriber (e.g., electric vehicle operator) that indicate one or more events of interest for which the subscriber wishes to receive notification messages. A set of one or more contact points associated with the subscriber is also received. The server receives data associated with the subscriber that indicates that a charging session at one of the charging stations has been established for an electric vehicle associated with the subscriber. The server detects an event of interest for the subscriber and transmits a notification message for that event to at least one of the set of contact points associated with the subscriber.

An external power supply connector attached to a vehicle-side connecting portion and control unit controlling the supply power to the vehicle-side connecting portion, supplying power from the vehicle to outside. The external power supply connector includes a body including an external connecting portion to an electric plug supplying power to a connected external device; a restricting member enables switching between restricting state wherein the electric plug is restricted from being attached and detached to and from the external connecting portion, and allowing state enabling the electric plug to attach and detach to and from the external connecting portion. A signal outputting portion outputs a signal to the control unit and detecting portion. The detecting portion detects the restricting state and allowing state of the restricting member. In allowing state, the signal outputting portion outputs a prohibiting signal from being supplied to the external power supply connector to the control unit.

An ECU performs processing including: a step of obtaining a pilot signal CPLT and a connector connection signal PISW; a step of determining, when a connector is attached, a type of the connector; a step of controlling, when there is a function corresponding to the type of the attached connector, the connector to be set to a lock state; a step of performing control corresponding to the attached connector; and a step of maintaining, when there is no function corresponding to the type of the attached connector, an unlock state of the connector.
