Vehicles that are capable of connecting to the AC grid are described that comprise a prime mover and at least one motor generator. In one embodiment, a vehicle may be constructed as a plug-in hybrid system and using the powertrain under controller instruction to either place power on an AC power line (to service AC grids) or to draw power from the AC power line to add electrical energy to the batteries on the vehicle. In some aspects, vehicles may test whether the power needed to service the AC power line may be satisfied by the on-vehicle batteries or, if not, whether and how much power to extract from the prime mover. In some aspects, vehicles may have a thermal management system on board to dynamically supply desired heat dissipation for the powertrain, if the powertrain is using the prime mover to supply power to the AC grid.

Powertrain configurations for hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (PHEV) are disclosed. One powertrain comprises: a prime mover; an electric motor-generator, said electric motor-generator mechanically coupled to said prime mover via a first clutch; a transmission, said transmission mechanically coupled to said electric motor-generator via a second clutch; a battery, said battery electrically coupled to said electric motor-generator, said battery capable of supplying electrical energy to said electric motor-generator; and a controller, said controller capable of supplying control signals to said prime mover, said first clutch, said electric motor-generator, said second clutch and said transmission such that said controller is capable of dynamically affecting a plurality of operating modes. Manual control modes for the vehicle and transmission of the HEV or PHEV are used for the purpose of optimizing power, efficiency and the use of either one of the energy sources obtained from off-board sources.
