Specific Fuel Use for ICE in Honda Insight Fig. 10. Fuel saving components of HEV in city transport 7. Options The serial PHEV is also good alternative for military vehicles and other vehicles for operation out of civilization and out of grid where the battery can be charged only from Diesel-generator. Here is not the advantage of night charging from the plug but the generator with battery can serve as an independent power source for local DC or AC grid 90 Electric Vehicles - The Benefits and Barriers from inverter. So it can be said that such vehicle is more plug-out than plug-in but its composition is similar maybe with higher ICE and generator power. PHEV without generator The last time concepts of PHEV suppose also solutions with mechanical connection of ICE to wheels in highway traffic mode when the EM and generator can be smaller and thanks shorter drive chain the fuel consumption can be reduced comparing with electric chain. Such concept can separate also the wheels driven by ICE and by EM and the typical frontwheel drive vehicle can be can be equipped with electric rear-wheel drive. Fig. 12. PHEV without Generator Because the charging from ICE is not very efficient and does not save the fuel it is possible to realize the vehicle where each axis is driven by one motor . For short distance trips the axis 1 is driven by EM supplied from battery and here can be also the energy recuperated from braking or downhill rides. For the long distance trips on highways the ICE drives the axis 2 which is connected to the first axis only by road surface EM does not help in drive but it can again recuperate and in low speed drive when the ICE does not work with high enough efficiency the driving torque from ICE can be bigger than is necessary and EM can in generator run the surplus energy change into EE and charge the battery. Instead of generator in here is the gearbox manual or automatic and the second reduction and .
