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). 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. A battery replacement in 1.5 min, flanked by slot-apps, allows a very high nominal user frequency of more than 800 cars per drive-through and day. High practical usage correlates positively with the double 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 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.
  • Maintaining of 12,500 station locations in Germany as alternative to millions of singularly charging pillars.
  • 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.
  • E-mobility in its new form secures the functionality and efficiency of smart grids.
  • Traditional filling stations will be maintained and used with respect to new mobility and the new energy. 12,500 transformed traditional stations could save up to 2.5 million plug-in-pillars, and thus grid-investments of up to atwo-digit billion-Euro-amount (see Germany).
