Patent ID: 8154151

Claim:
An intelligent energy transfer system for controlling transfer of power between a vehicle and an external energy system, the intelligent energy transfer system comprising: a configurable switching system electrically coupleable to the vehicle, the vehicle comprising one of an electric vehicle and a plug-in hybrid electric vehicle having a vehicle energy system (VES) thereon configured to store electric power; and a processor electrically coupled to the configurable switching system and configured to control the configurable switching system, the processor being programmed to: determine a state of charge of the VES; compare the state of charge of the VES to a state of charge threshold; if the state of charge of the VES is below the threshold, then implement a charging protocol to cause power to be transferred from the external energy system to the VES; otherwise, if the state of charge of the VES is above the threshold, then implement a load protocol to cause power to be transferred from the VES to the external energy system; wherein implementing the charging protocol comprises: determining power parameters of the VES; and controlling the configurable switching system based on the power parameters of the VES so as to condition power provided from the external energy system to the VES; and wherein implementing the load protocol comprises: determining voltage and current characteristics of the external energy system to be supplied power from the VES; providing power to the external energy system if voltage and current characteristics of the external energy system match voltage and current characteristics of the VES; and preventing the VES from providing power to the external energy system if the voltage and current characteristics of the external energy system do not match the voltage and current characteristics of the VES.
