Selectable options to display a detailed view of information related to an electric charger associated with an electric charger category from among multiple electric charger categories may be provided.

Various disclosed embodiments include illustrative controller units, systems, vehicles, and methods. In an illustrative embodiment, a controller unit includes a communication component, a controller and a memory. The communication component is configured to communicate with a direct current charging device. The controller is configured to communicate with the communication component and the memory. The memory is configured to store computer-executable instructions configured to cause the controller to determine a target location, receive location information of a vehicle, receive state of charge information, determine a charging request in response to the target location, the location information of the vehicle, and the state of charge information, and send, via the communication component, the determined charging request to the direct current charging device connectable to the vehicle.

Aspects of the disclosure provide a battery pack and a method for charging the battery pack externally. The battery pack can include a charging port configured to charge the battery pack, a cooling circuit configured to cool the battery pack in a vehicle, and a cooling interface configured to connect the cooling circuit with an external cooling device that is external to the vehicle. The charging port and the cooling interface can be integrated into a charging port assembly, the cooling interface has an inlet port and an outlet port that have high pressure quick disconnect leakless fittings, and the battery pack is configured to be charged externally via the charging port. The battery pack can include a plurality of isolating devices configured to determine whether the cooling circuit is connected to the external cooling device.

A ground power supply apparatus for transmitting power to a vehicle by noncontact has: a plurality of power transmission apparatuses for transmitting power to the vehicle; at least one detection device for detecting a signal emitted from the vehicle using narrow range wireless communication; and a controller for controlling the power transmission apparatuses. The power transmission apparatuses are arranged in a road aligned in a direction of advance of the vehicle. One first detection device is arranged so as to enable detection of the signal at an upstream side from the most upstream power transmission apparatus. The control device controls transmission of power from power transmission apparatuses other than the first power transmission apparatus positioned the most upstream, based on the signal detected by the first detection device and power transmission result information at the power transmission apparatus positioned upstream of that power transmission apparatus.

Charging stations for electric passenger vehicles are provided. A charging station can have two levels to accommodate passenger vehicles, with multiple spaces on each level. At least one of the spaces can be a charging platform that can charge an electric passenger vehicle located thereon. The charging station can be mobile, for example, by having its main body structure be sized such that it can be transported via a tractor trailer or other large transport vehicle.

Technology for charging at least one battery is described. An aspect of the technology involves charging a battery using alternating current (AC) power by periodically stopping (602) charging of a battery of a mobile energy storage and power consumption device (16A) with AC power, and when charging of the battery with AC power is stopped, initiating (604) a direct current (DC) power charging communications cycle for the battery, in which the initiating the DC power charging communications cycle includes obtaining (606) state of battery related information for the battery by transmitting, over a communication link or interface, a request signal to a charging control device at the mobile energy storage and power consumption device indicating DC power charging mode of operation.

Methods and systems are provided. One method includes processing operations to share electronic keys (e-keys). The method includes receiving a request to share an electronic key (e-key) of a vehicle with a recipient device. The request to share the e-key is initiated by sending a message to the recipient device using a sharing device. The method includes processing the request to validate the request to share the e-key, as received from the sharing device having associated therewith a registered owner e-key. Processing the request includes generating the e-key securely by the sharing device and registering the e-key that was generated with a server associated with a manufacturer of the vehicle. The method includes enabling the e-key for use on the vehicle by the recipient device responsive to said processing of the request. The request to share the e-key includes enabling a setting to apply a privilege level for use of the vehicle via the e-key. The privilege level provides one or more conditions of use of the vehicle via the e-key.
