Challenge / Goal
In Stockholm Plug-in Electric Vehicles (PEVs) have doubled in number each year for the past four years and are expected to continue to do so for the years to come. Developing charging infrastructure is an important measure to respond to citizen needs and facilitate the transition to an improved vehicle fleet in cities. Regarding different ways of recharging PEVs, the City of Stockholm has installed a fast station and five to ten normal charging stations within the GrowSmarter project. This use case fouced on normal charging station where you charge the car battery over a longer time, usually overnight, at a low current.
Fortum is providing public and private normal-speed charging stations in cooperation with the housing company Stockholmshem. The normal-speed chargers are located outside apartment buildings to allow residents to charge their electric vehicle (EVs) during the night. All chargers are equipped with two outlets for EVscharging, enabling two cars to charge at the same charger at the same time. The outlet of the chargers meet the EU standard Mode3Type2. Each outlet delivers 16A 230V, which gives a power of 3.7 kW. This power is enough to fully charge a regular EV within 8-10 hours.
Some of the chargers are private and only available for the residents to charge and some chargers are public chargers where a first-come, first-served rule are applied. Customers have to pay for the charging and a pricing model with a given cost per hour is applied. The price is approximately 60 cents to 1 Euro per hour of charging. Payments are processed using RFID tags or via a web app that is connected to the customer's credit card. It is possible to register for charging at the site so no prior registration is needed.
