Consider the simple model for a Hybridelectric vehicle shown:
model the gas
powered generator as a constant current source supplying 50A, the Battery pack
as having constant voltage of 120V, and the electric motor as a variable current
sink which can also work as a regenerative brake, returning current to the battery.
