EVwire brief: IONITY has started adding battery buffers to its charging parks, with the European charging network switching on a 1,028-kWh (1 MWh) battery storage system at its Wertheim site in Germany.
The system pairs four modular Sungrow units with a maximum output of 500 kW, letting IONITY grow Wertheim from four to six Alpitronic HYC400 chargers without waiting for a medium-voltage grid upgrade, which the company says can take up to three years. Two more ABB chargers with peak power of up to 350 kW are set to follow, bringing the site to eight charging points.

IONITY plans to roll out around 50 battery storage systems across Europe in 2027, with a combined capacity of more than 20 MWh. Christoph Strecker, IONITY's Head of Rollout, told electrive that more are coming:
"Battery storage systems play a key role in this: they enable us to open up new locations, use electricity more efficiently, and take on an active role in the energy system in the future. Wertheim is just the beginning.
"With the planned Europe-wide expansion, we want to take the next big step towards a smarter, more powerful, and more flexible charging infrastructure."

Context:
Wertheim's setup is built around a common bottleneck for fast-charging operators. The site sits off the A3 motorway next to the Wertheim Village outlet centre in Baden-Württemberg, and an energy management system decides how much power each session draws from the grid and how much from the battery.
Hemsbach, also in Baden-Württemberg, is next in line, with 12 fast-charging points, a solar canopy of more than 223 kWp and a battery of more than 2 MWh that will also store the power generated on site.
The battery rollout comes as IONITY works toward a much bigger network. When it lined up new financing in May 2025, the company said it was aiming for about 13,000 high-power charging points across more than 1,300 sites by the end of 2030, roughly double its network at the time.
