3.2.1 Meeting customers' mobility needs
People want to be able to use their vehicles to go where they want, when
they want. Although the size and type of vehicle do in fact place some
restrictions on this freedom, our perception as car owners is one of almost
unlimited personal mobility.
EVs must offer an attractive alternative with regard to this critical factor.
They can be successful only if they offer sufficient driving range and are
able to take their owners where they want to go.
Driver 1: Driving range
PHEVs and EVs with range extenders have a very limited driving range in
pure electric mode, approximately 10-60 km. But this does not limit their
overall mobility. The reason, of course, is that they can switch to the backup
mode – a gasoline engine. The disadvantage of this technology from
the customer's perspective is that the electric driving range, which would
be the preferred driving mode, is strictly limited. Interior space may also
be restricted due to the package requirements of having two powertrains.
One alternative is a pure EV with its driving range determined by the
energy capacity of the battery system. As we saw in Chapter 2, it is unlikely
that such vehicles could offer driving ranges comparable to ICE-powered
vehicles within the next ten years.
