Charging Infrastructure – Room for Improvement<br />

The charging infrastructure plays a key role and there is an opportunity to develop the<br />

infrastructure further and to make it more readily available. Enhancing PHEV performance<br />

also requires users to change their habits. We can see from the interim results that users<br />

recharge roughly 0.9 times/day and that while the procedure to charge the vehicle remains<br />

easy, the cable ergonomics remain a concern in terms of handling.<br />

Users need to get accustomed to charging their vehicles. This is an entirely new habit,<br />

which still appears as constraining for a few users. From the initial results it appears that<br />

charging occurs mainly at private parking charging points (91%) and at the workplace (72%).<br />

Recharging usually takes place during peak hours, at 08:00 when the users reach their<br />

workplace or at 19:00 when back at home.<br />

There are several key learnings for the Urban Community of Strasbourg. Despite offering<br />

free electricity and convenient city parking spots, the usage of the 27 public road and public<br />

parking lot charging points was low. User surveys underline the need for clear communication<br />

on the locations of charging points and their operational status.<br />

Looking Forward<br />

In summary, we can see that the PHEV meets the expectations of users and provides tangible<br />

fuel savings while providing genuine driving pleasure and daily ease of use. It also encourages<br />

users to adopt a more eco-friendly driving style. Additionally we can identify some key factors<br />

to optimise environmental performance by :<br />

Ensuring frequent recharging, in line with usage of the vehicle<br />

Recharging the battery fully when recharging<br />

Increasing user awareness and training to allow customers to maximise the vehicle<br />

performance.<br />

The interim results and recommendations provide valuable input towards the launch of the<br />

PHEV in 2012, with planned sales of 50,000 units globally, and 6,000 in Europe.<br />
