for swapping batteries are discussed and divided into five stages. The analysis result
is used to help the authors see the feasibility of each candidate design strategy. In
Sect. 3.2, eighteen feasible design strategies are selected based on the feasibility and
then ready for use in the questionnaire design.
4.3.1 Behavior Analysis for Battery Swap
The current battery swap service systems in Taiwan contain several components: (1)
battery, (2) automatic charging station that provides charged batteries ready for swap,
(3) cloud system providing data storage, information processing and computing, and
(4) scooter. Users use their cell phones to connect with the four. To find useful and
feasible persuasive design strategies, this study analyzes the user experience and
related behaviors in the current swap service systems. The results can help identify
whether a candidate strategy could be implemented and current users’ behavior could
be changed and lead to the less visited stations. If the answer of the question is
positive, the candidate design strategy is called a ‘feasible’ one. A typical battery
swap process contains five stages, including:
(a) Being aware of battery status: Users check the battery status by inspecting the
control panel of the scooters. The panel shows how much electricity power is
left by using ten blocks where each block represents one tenth of electricity left.
(b) Finding out nearby charging stations: Users find nearby charging stations from
the map using the app provided by service providers. The locations of the
charging stations are highlighted on the map noting how many fully charged
batteries are available in each station.
(c) Selecting stations: Users select an intended charging station among the ones
shown on the map based on users’ need and other personal consideration.
(d) Checking detail information of the selected station: Users look into the detail
of the selected station including the route and additional information of the
surroundings of that station.
(e) Swapping battery on the station: Users interact with the unmanned charging
station and physically swap the batteries inside the scooter and the station. If
the station is very popular and users take some time to reach the spot, users may
find there is a waiting line or no fully charged battery available and then need
to find another station.
The goal is to persuade users to choose and use the charging stations that are
less visited. The persuasive design could be implemented in the five stages as
mentioned above. Although those popular charging stations have the advantages
like near popular spots, easy to reach, on the road of good traffic flow, or near important public facilities, users may face the risk of finding no battery available. The
authors keep the three elements of the behavioral model (Fogg 2009) in mind and
consider the characteristics of the current swapping behavior as presented above to
