Experience electric vehicle: the case of fast charging
RISE, Swedish ICT, Viktoria.
2012 (English)Report (Other academic)
Abstract [en]

The report describes the user study evaluating the two installed fast chargers. In detail, the goal of the user study is to investigate the effect of having access to fast chargers on the drivers’ attitudes and experience of electrical vehicles (EV). In addition, recommendations on how to evaluate these kinds of test environments are provided. The study includes interviews and questionnaires before (test occasion 1) and after (test occasion 2) a trail period of using the fast chargers to capture any changes in attitudes and behaviour. Two test site were included in the study. A total of 5 individuals, accessing one of the two test sites, participated in the study.

The ability to quickly fully charge the vehicle were emphasised as opposed to the flexibility and ability to use the vehicle more often. This is contradictedn by chargers only being filled to 80%. Also, the fast charger takes longer in winter (45 min as compared to 20 min). All of this lowers the appeal and usage of fast charging. The participants that did experience an added value of the fast charger were those that would use the charger toincrease the efficiency of the vehicle, in e.g., a car pool. The participants that did not experience an added value of having access to a fast charger at the test site were those that (1) not represent the correct user group (2) have had access to the EV for a long time and they already match their daily routine according to the range of the EV, (2) do not have a need to drive long distances, (3) do not have a natural placement of the fast charger for it to play a significant role in their driving; (4) the amount of extra energy the fast charger provides does not play a significant role in their daily driving. However, some interesting (significant) changes in attitudes and behaviour were identified in the survey that needs further investigations (participant alternated from completely agree to completely disagree). The following aspects were identified as influencing the use of the fast charger: Location, amount of charge, cost of charging, time, current battery level, driving distance, safety of the place, and timing. In particular the location of chargers was highlighted as determination of behavioural pattern. General public location may have a limited effect on individual EV users. However, from a company perspective, fast charger may be useful as it directly influence the efficacy of the usage of EV.
