ELECTRIC VEHICLE CONTROL BASED ON OPERATING COSTS ASSOCIATED WITH POWER SOURCES

摘要

A plug-in hybrid electric vehicle operates the engine and/or traction motor in response to energy costs or prices received from an external source, such as a user or network. The vehicle can include a battery; an engine; an electric motor; a memory to store a battery charge point, and a controller to modify the battery charge point in response to arbitration criteria to control battery charging from the engine. The arbitration criteria can be based at least partially on fuel cost for the engine. The arbitration criteria can be based at least partially on electricity cost. The arbitration criteria can also include location of the vehicle. The controller may alter a deadband between charging the battery with the engine and discharging the battery to power the traction motor based on the arbitration criteria.
