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 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.
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).
