Ionity plans to install 50 battery storage systems at its charging parks in 2027 to manage energy demand more efficiently. This expansion builds on the successful pilot of its first battery-integrated station in Wertheim, Germany, which opened in October 2026.
Why it matters
Integrated battery systems allow the company to increase charging capacity at locations before permanent grid upgrades are finalized. This technology bridges gaps in power availability, helping to meet the growing demand for fast-charging infrastructure.
The company aims to reach a total of 20 MWh of battery storage capacity by 2027. Individual sites like the project in Hemsbach feature battery systems with capacities exceeding 2 MWh alongside a 223 kWp photovoltaic canopy.
The players
Ionity
This is a joint venture founded by major automotive manufacturers that operates a high-power charging network for electric vehicles across Europe.
Sungrow
This global supplier provides the modular power electronics and energy storage solutions integrated into the charging park infrastructure.
ABB
This technology company manufactures the high-capacity charging hardware used to deliver electricity to electric vehicles at the network sites.
The details
The system utilizes an intelligent energy management unit to distribute power between the grid, the battery storage, and the charging points. The current solution in Wertheim provides 500 kW of power output and has enabled the site to grow from four to six charging points.
Timeline
The first battery-integrated charging park opened in Wertheim in October 2026.
Ionity plans to install 50 battery storage systems throughout 2027.
Roadmap
Integrating stationary energy storage systems into charging networks represents a shift toward decoupling charging speed from immediate grid capacity. This strategy allows networks to bypass lengthy utility infrastructure lead times while positioning themselves to participate in future energy trading services.
Drivers can expect increased charging availability at high-traffic sites as storage systems remove bottlenecks caused by limited grid connections. These upgrades ensure that high-power charging stations can operate at their maximum potential regardless of local peak energy demand.
The takeaway
Energy storage serves as a vital buffer for modern high-speed charging networks to overcome local utility limitations. Implementing these systems allows operators to scale their service footprint rapidly while maintaining high performance levels for individual users.
