Electric Vehicle Charging Infrastructure Typologies
Introduction There are four key electric vehicle charging infrastructure typologies presented in the ZEVI Strategy including: • Home-Charging: The majority of charging will be home charging which will take place off- street. • Residential neighbourhood charging: these are charging systems catering for residents who do not own a driveway or have access to private parking. This charging network will also support local businesses, taxis, visitors, etc. as well as potentially providing faster charging options to those who have domestic charging facilities. • Destination Charging: Provide top-up charging at key destinations • En-route charging: Provide higher-speed charge points at strategic locations on the road network. Cork City Council’s Electric Vehicle Infrastructure Strategy is primarily focussed on the delivery of residential neighbourhood charging infrastructure which can be further broken down into two types of charging facilities: • Neighbourhood Charging Stations : These charging stations are typically normal speed installations with a total charging speed of 22kW shared between 2 charge points at each charging station. Typically, 2 such charging stations (Total Output Power – 44Kw) will be provided, possibly on a phased basis (i.e. initially 1 charging station followed by a second depending on demand and available ESB network capacity) • Community Charging Stations: These are fast charging stations with a total charging speed of between 150kW and 300kW shared between 4 to 8 charge points The spatial distribution of public Community Charging Points will reflect the current and potential delivery of destination charging stations as both charging infrastructure types have the potential to serve similar demands of the community (i.e. short duration – high capacity stations). For neighbourhood charging stations the vast majority of these will be public provided facilities.
Neighbourhood Charging Stations Neighbourhood charging stations are normal speed installations with the primary objective to facilitate residents who do not have access to a private off-street parking space. Their provision is to replicate, as best possible, domestic charging although it is acknowledged that neighbourhood charging stations will need to be shared among a group of residents.
Charging Times Typically, electric vehicle batteries vary in size from around 40 kW (Nissan Leaf) to 90kW (Jaguar I- Pace), although both smaller and larger battery sizes are available on the market currently. The average battery size is in the region of 60 kW (Hyundi Ioniq 5, Skoda Enyaq, Tesla Model 3, Volkswagan ID.3). The estimated charging time to deliver an 80% increase in an average battery life utilising a normal charging station will be between 5 and 9 hours (depending on the number of vehicles charging at the same time, weather conditions, battery size and state, etc…).
