International Classification:

H01M 10/46

US Classification:

320104

Abstract:

A server of a network-controlled charging system for electric vehicles receives a request for charge transfer for an electric vehicle at a network-controlled charge transfer device, determines whether to enable charge transfer, and responsive to determining to enable charge transfer, transmits a communication to the network-controlled charge transfer device that indicates to the network-controlled charge transfer device to enable charge transfer.

International Classification:

G06Q 20/00

US Classification:

705 39

Abstract:

A method of collecting electric vehicle power consumption tax for charge transferred between a local power source and an electric vehicle comprises: providing a network-controlled charge transfer device, charge transfer being controlled by a controller, the controller being connected to a network for communication to a server; requesting by an operator of the electric vehicle to the controller for charge transfer; relaying the request from the controller to the server; determining by the server, from geographical tax rate data and the geographical location of the network-controlled charge transfer device, an applicable tax rate on the charge transfer; enabling charge transfer by communicating from the server to the controller to activate the control device; monitoring the charge transfer using a current measuring device, the controller being configured to monitor the output from the current measuring device and to maintain a running total of charge transferred; detecting completion of the charge transfer; and on detecting completion, processing payment with said payment source, which may include deducting the cost of charge transfer from a subscriber account containing pre-transferred funds, and disabling charge transfer; wherein the request for payment includes the electric vehicle power consumption tax.

International Classification:

H02J 7/04

US Classification:

320165, 320109

Abstract:

An electrical vehicle charging station establishes a charging session with an electric vehicle which includes energizing a power receptacle in the charging station and receiving a charging cord at the power receptacle. While the charging session is established and responsive to detecting that a charging connection between the electric vehicle and the electric vehicle charging station has been unexpectedly disconnected, the power receptacle is de-energized to prevent electricity from flowing through the charging cord.
