Embodiment Construction

[0012] Referring now to the drawings, which are shown for purposes of illustrating certain exemplary embodiments only and not for purposes of limitation, figure 1 The electrical power distribution subsystem is schematically shown, including a charge management system for charging an electrically driven vehicle. Like reference numerals refer to like parts throughout the detailed description. The charging management system includes a charging control scheme 41 for remotely managing the charging of individual host vehicles 10 at charging locations 20 using electrical power derived from a stationary electrical power source, such as the electric utility plant 60 . The charging management system includes a remote access server 40 that uses information obtained from the utility grid monitoring system 50 and the communication network system 30 to implement a charging control scheme 41 . Communication can take the form of either wireless or hardwired communication or both.

Abstract

A method for managing electrical charging of an electrical energy storage device for a subject vehicle using electric power originating from a stationary source of electrical power includes providing a database including respective geographic locations of a plurality of electric power distribution subsystems, receiving a request from the subject vehicle for electric charging power, resolving a geographic location of the subject vehicle to a subset of the plurality of electric power distribution subsystems, determining an electric power reserve capacity for each electric power distribution subsystem in the subset of the plurality of electric power distribution subsystems, and allocating a magnitude of electric power for charging the subject vehicle based upon the electric power reserve capacity for each electric power distribution subsystem in the subset of the plurality of electric power distribution subsystems.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 174,130, filed April 30, 2009, which is incorporated herein by reference. technical field [0003] The present disclosure relates to recharging of electric vehicles. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Vehicles driven using electric power include, for example, electric vehicles, range-extended electric vehicles, and plug-in hybrid electric vehicles. Electric drive vehicles are configured to reduce direct consumption of fossil fuels. The electrical energy storage devices of these vehicles may need to be periodically recharged. Such charging can be done, for example, at the owner's residence. Charging at a remote location may be required. [0006] Simultaneous charging of multiple vehicles in a local area ...
