It has been shown that heat engine-battery hybrid vehicles use much less petroleum than conventional vehicles, while the batteries are able to supply energy to remove part of the road load from the engine. Once the available energy in the batteries has been used, the fuel consumption increases. The results presented show that consumption is lowest after battery depletion if the engine only drives the vehicle, the battery only being recharged by the energy available from regenerative braking. By adjustment of the control strategy suggested, fuel consumption can be minimised for any trip length for particular driving cycles. Of the hybrid configurations considered the parallel hybrid using a Perbury continuously variable transmission gives the lowest consumption. Batteries of four different capacities were considered to find the minimum practical size of energy storage unit for the vehicle.
