at the North American International Auto Show (NAIAS), Cobo Centre, Detroit, the
automaker BYD Auto displayed a PHEV and BEV as shown in Figure 1.42.

The Electric Power Research Institute (EPRI) performed a customer survey to deter-
mine the thresholds of desirable hybrid performance and costs [20]. Figure 1.43 is an
educational slide used to inform the survey participants of the distinction between a
CV and an electric vehicle.

Survey participants were asked about the necessity of plugging in their vehicles
versus filling station visits to pump gasoline. By and large the respondents were
amenable to plugging in their vehicles rather than seeking out a filling station.
There was concern, however, by apartment and condominum dwellers over
the availability of a charging outlet, plus a caveat to remember to plug the vehicle
in. The EPRI survey then introduced a CS hybrid, H0, and plug-in hybrid, H20 to
H60, to test the waters on hybrid vehicles with and without electric-only range.
