Swedish EV Charging Site Overcomes Grid Constraints With Integrated Storage

A new electric vehicle charging site in Rockneby, Sweden, has launched with 360kW of combined fast-charging capacity despite being limited to a 63A grid connection. The project, located on the E22 highway in Kalmar Municipality, utilizes two 180kW ZOE DC fast chargers from ZOE Energy Storage, each paired with 218kWh of integrated battery storage and on-site solar generation.

By incorporating battery storage and solar power, the system avoids the need for a larger grid connection typically required for such high-power charging installations. The batteries store energy from the solar panels and discharge it during vehicle charging sessions, reducing the immediate demand on the local power grid. Emaldo, which managed the project from orchestration to commissioning, described the site as a blueprint for rural electrification where grid capacity limits and high connection costs have previously hindered development.

The initiative was supported by Ladda Landsbygden, a regional program managed by Miljöfordon Sverige and funded by Region Kalmar County and local municipalities. The project also received 50 percent co-funding through Klimatklivet, an investment grant scheme operated by the Swedish Environmental Protection Agency (Naturvårdsverket).

Badie Nabi, a local business owner who initiated the project, stated that the installation serves as a contribution to the transition toward renewable energy and electrification in rural areas. Jonas Lööf of Miljöfordon Sverige emphasized that expanding charging infrastructure to rural regions is essential for the national transition to electric vehicles. Emaldo sales manager Henri Stendalen noted that the project demonstrates that future energy solutions can be implemented effectively even in areas with challenging grid conditions.
