Integration of battery storage into long-distance EV charging network (Project FAST-E SK/CZ)Electric Mobility

For ZSE Slovakia, a member of E.ON Group and charge point operator, the objective was to analyse the future charging network requirements and technology integrated with the utility industry.


The Operator needed to evaluate the potential of batteries at EV fast-charging sites with limited grid capacity to optimise connection and operation costs. ZSE also planned to explore the technical requirements of ultra-fast charging and the business impact of 100+ kW EV charging.


We delivered an in-depth technical evaluation of battery storage options, including a cost-benefit analysis. In addition, we also developed an analysis of synergies between load balancing of the local grid and battery-assisted charging with consideration of ultra-fast charging.
