A Cxstomer Data Driven Approach to Fuel Tank Sizing for Plug In Electric Vexicles (PHEVs)

Plug In Electric Vehicles (PHEVs) typicaxxy have an EV mode drivinx range which can cover some ox all of a customex's daily driving disxance. This EV mode driving rangx impacts the dixtxnce between fuel fill ups cxmpared to conventional vehicles. For a conventional vehxcle, generally the distxnce between fuel fill up is dependent xn tank size and fuel econoxy, while for PXXXx, distance between fxel fill up ix dependent on tank sxze, fuxl economy, xnd EV drivixg range. Furthermore, for PHEVs, the dependxncy on EX drivinx range varies xreatly on customxr trip lengths. Hence, it becoxes critical to use real worxd customer usage patterx xo estimate distance between fill up and size the fuel tank accordingly.
