Embodiment Construction

[0023] Renewable energy power generation facilities (here, "REPG facilities") use one or more of the following renewable energy sources to generate renewable electricity: solar panels; wind turbines; geothermal; ocean waves, etc. Usually, this kind of renewable energy is sold to utility companies for profit and pushed to the grid managed by the utility company. The utility company monitors the supply of electricity on the grid and the demand for electricity on the grid. Historically, the demand was greatest between 2:00PM and 8:00PM. The supply of energy on the grid will change. Utility companies try to maintain a balance between the supply and demand of electricity on the grid.

[0024] In some implementations, the REPG facility may be an individual homeowner who has solar panels in his residence, or a large facility that generates renewable energy on a commercial scale.

[0025] Sometimes, utility companies cannot accept renewable energy from REPG facilities because doing so w...

Abstract

The disclosure includes a system and method for charging and discharging a Plug-in Electric Vehicle ("PEV"). The method may include determining that first event data describes a Renewable Energy Output Control event ("REOC event") including instructions directing a Renewable Energy Power Generation facility ("REPG facility") to not output power to a power grid during a time period specified by the REOC event. The method may include the REPG facility charging a battery system included in a PEV during the REOC event. The battery system may be coupled to the REPG facility via a coupling that does not including the power grid. The battery system may be charged by the REPG facility via the coupling with power generated by the REPG facility during the first duration of the REOC event so that the REPG facility continues to generate power during the REOC event.

Description

Technical field [0001] This manual relates to the optimized charging and discharging of plug-in electric vehicles. In particular, this specification relates to optimizing the charging and discharging of plug-in electric vehicles according to one or more of demand response events and renewable energy control events. Background technique [0002] Renewable energy is becoming increasingly popular. Power plants that operate renewable energy-based power generation facilities can push the electricity they generate to a grid owned and operated by a utility provider. Utilities purchase renewable energy from operators of renewable energy-based power generation facilities. Sometimes, utility companies cannot purchase or receive renewable energy, because doing so will cause an imbalance in supply or demand in the grid. The utility company issues a renewable energy output control event to notify the renewable energy-based power generation facility that the utility company cannot purchase ...
