As Singapore adopts the Electric Vehicles (EVs) and phases out convention vehicles running on Internal Combustion Engine (ICE), the government has sought to deploy 60,000 electric vehicle chargers in Singapore as part of the Singapore Green Plan 2030. One major hurdle to EV adoption is charging – both the charging time and availability of charging infrastructure. As the world phases out ICE Vehicles, more understanding of EV parking and charging is required to manage the worldwide demand and supply of charging infrastructure. This study aims to better understand the Charging and Parking behaviour and characteristics of EV Drivers in Singapore, including usage patterns and charging preferences, to identify problems affecting the usage, access, and supply of EV charging infrastructure. Existing research on charging and parking behaviours of EV drivers from countries with a more developed EV infrastructure and ecosystem will also be reviewed and referenced in this study to assess the viability of using these results to predict EV charging infrastructure demand in Singapore. To better understand EV Drivers' charging and parking behaviour in Singapore, a structured survey is conducted to interview 82 EV Drivers and other Drivers on their perception of EVs, their views on EVs, and any concerns currently preventing the switch to EVs. The results of the small-sample survey showed a distinct difference in charger usage patterns in Singapore with existing research, likely due to the unique housing situation in Singapore, with 81% of residents living in HDB flats which necessitate the use of public, shared EV chargers. The findings from this study provided information on the charger usage patterns of EV drivers in Singapore and showed that EV drivers in Singapore are receptive to the use of economic incentives and disincentives to manage EV charging infrastructure and would tailor their charging and parking behaviour depending on fees, incentives, and penalties in place.
