E-Power-Station of the Future

The system advantages in brief

Faster, cheaper and more strategic

Our start-up, founded in 2019, is a 50:50 joint venture between German infrastructure experts and Aulton Dianba, the Chinese market-leader for rapid battery swapping stations (time-maximum for cars: 1.5 min with a core time of 0.33 min). We have developed safe swapping solutions for cars and small transporters (through the car bottom), for buses, trucks and utility vehicles (sideways), both using the drive-through-approach to minimize the procedure duration – especially for e-fleets. This fast totally automated swapping of batteries (net time: < 30 seconds!) enables an efficient uncoupling of mobility and energy with enormous lifetime-effects for the used batteries, and tremendous cost-savings for the needed smart grid investments (see also better connection power). A battery replacement in 1.5 min, flanked by slot-apps, allows a very high nominal user frequency of practically up to 800 cars in 24 hours. High practical usage correlates positively with the doable prices, which can be lower than the electricity supply prices of all common plug-in-pillars (AC and DC) or convenient AC and DC-home connections.

Less burdens and more synergy for the systems

A battery recharging time of ≤ 0.5 C (2 hours) through our system-immanent storage-based recharging-technology (flexible stationally charging) avoids spot burdens (see local power supply systems) and provides additional cost advantages of up to a two-digit billion Euro amount (see Germany). Furthermore we will use the battery aggregations for offering storage capacities for the smart grid which needs a permanent storage reserve to compensate the negative effects of the volatilities of the green energy supply (see primary-reserve, secondary-reserve, and minute reserve).


Compared to AC-plug-in the advantages of “7 in 1” are totally unbeatable: no time loss, lower kWh-prices, lower investment-costs, no need to implement decentral plug-in-pillars (1 AC-pillar for 5 e-cars) with their risky extra costs for maintenance, overall monitoring, vandalism-aftercare and it relies on existing and well established infrastructural junctions (see traditional filling stations) which minimized costs.

Compared to all forms of decentral DC-plug-ins our advantages are: faster than every DC-plug-in, very lower kWh-prices through lower investments, higher frequencies and Dual use-incomes, much longer battery lifetimes through flexible, careful charging and the refreshment-effects in the technical process of flanking the smart grid-stability (up to factor 5). Other cost-advantages result from reducing the recycling-expenses and using the old batteries directly as second life-components for the safety-storing in the context of arranged smart grid storage provision (per 2 MW normal storage 1 MW safety-storage).

Additional advantages

  • One battery world instead of two separated worlds.
  • Efficient and not complicated coupling of mobility and energy for the storage needs of future virtual power plants.
  • E-mobility in its new form secures the functionality and efficiency of smart grids.
  • Permanent short-term-assessment (by photon-technology) of the batteries in the process of swapping/recharging/using/recharging/swapping, and lower battery demand due to the lifetime-based overcompensation of the normally required battery-packages are also strong arguments.
  • Traditional filling stations will be maintained and used with respect to new mobility and the new world of energy. 12,500 transformed traditional stations could save up to 2.5 million plug-in-pillars, and thus grid-investments of up to a two-digit billion-Euro-amount (see Germany).
