The battery swap in max. 1.5 minutes (technical swap time: 20 seconds!) eliminates waiting times that occur with the plug-in system. This means safe e-mobility without the expensive loss of time. This component can be used alone or in combination and ensures productive fleet operation.
Battery swap leads to higher user frequencies (up to 1000 swaps per day) whereby e-filling stations can then offer discount prices, classic convenience, dual-use storage service as well as in-system grid relief (system-controlled charging instead of grid problems due to permanent battery aggregation).
Centralized plug-in systems guarantee controlled charging with more than 24 plug-in connections. This includes normal plug-in (AC charging) and fast plug-in (DC charging). The energy storage system (usually: 2 x 0.7 MW containers) is charged in line with the grid and thus controlled. This can eliminate the charging station dilemma (see extreme allocation, over-supply obligations) in many places.
Additional information on the standard plug-in hub:
The Standard Plug-in Hub is an energy unit with two 20-foot containers that can be charged at low cost overnight or by container swap. In cooperation with large wind farms, self-charging e-container trucks transport filled battery containers from nearby wind farms to the "7 in 1" stations, where the empty containers are immediately replaced. This enables very low plug-in prices due to the minimal cost of excess green energy.
In superhubs, recycled used batteries can be provided as storage for secondary and tertiary control power and for redundancy, and active vehicle batteries can be enabled with the help of power converters, transformers, and energy and battery management systems to largely meet the increasing demand for balancing storage systems (connecting the grid and mobility).
This balancing power is part of the compensation required in the context of energy provision to cover energy losses and minimize feed-in-related power fluctuations (Section 3 EnWG). It is purchased by the transmission system operators and its costs are passed on to those responsible for the energy deviations (balance responsible parties).
It is remunerated at a capacity price (in €/MW) that rewards the available provision of the balancing power; in the case of secondary or tertiary balancing power, a decentrally defined additional price (in €/MW) is paid for real use (exception: primary balancing power per ENTSO-E).
A battery charging time of ≤ 0.5 C (2 hours) through our system-immanent, storage-based stationary charging technology (flexible charging) offers additional cost benefits of up to tens of billions (see Germany). Positive storage effects for the smart grid, which permanently needs control energy for its volatility problems, can be ensured by the superhubs. They thus become essential system-securing elements of the targeted renewable energy supply and the future operation of virtual power plants (see volatile sources).
Due to the very high nominal user frequency of practically up to 1000 e-cars per day and the volume advantage of the e-filling stations (superhub), the required electricity quantities can be purchased at 5-6 cents/kWh in the best case, if the additional costs from electricity generation, electricity distribution and traditional taxes/duties can be contained. Furthermore, additional revenues are generated by the provision of balancing power, so that all these factors together could enable a kWh price of about 20 cents for the consumer. Thus, in the medium term, the system offers lower electricity supply prices than any standard plug-in (AC and DC) pillars or ordinary AC and DC house connections, and becomes competitive with "fossil" drive types.
A standard swap station requires a maximum of 3 million kWh per year. A network of 30 normal swap stations requires more than 80 million kWh per year. These quantities are exceptionally high and ensure optimal electricity purchase prices.
The Super Hub offers an attractive vision for future gas station use, including familiar convenience and services that are common today, such as car washing, night shopping, etc. Heavy use could also ensure sufficient revenue in additional service areas.
The lithium-ion batteries currently in use are exorbitantly conserved in the super hub if they are not charged quickly but gently in ≤ 0.5 C (2 hours) after a battery swap and then used for continuous grid stabilization (see control power).
Due to the system-immanent, storage-based stationary charging technology (flexible charging), punctual loads are comprehensively avoided, and the car batteries are kept efficient by the use of control power (overall lifetime effect: factor 4-5 compared to fast charging).
Through controlled recharging (at least ≤ 0.5 C) and the provision of storage capacity (see control energy), the e-filling station of the future itself contributes to blackout prevention. The mobility/grid sector coupling creates a win-win situation: the battery units are used to offer storage capacities for the smart grid, which needs a permanent storage reserve to compensate for the negative effects of the volatilities of the green power supply (see primary reserve, secondary reserve and minute reserve) and to relieve the smart grid. Thus, switching stations and virtual power plants should be managed as a common system.
With the successively growing infrastructure of the super hub system, several billion euros in grid expansion investments can be saved nationwide without risk. These would be available above all to the municipalities for other tasks in connection with the energy and mobility turnaround.

Our product of the future is called SWAPTOPUS® and uses the freshly charged batteries of the swap station for 100 MWh and more per day to provide storage energy for the volatile power grid of the future. The SWAPTOPUS is an energy station for mobility and the grid. The e-filling station becomes a car battery storage power plant without loss of function, e.g. for balancing energy or "peak shaving".
The battery swap station storage potential is used for:
The additional demand for batteries can be far more than compensated for in the "SWAPTOPUS®" system through greater efficiency and long battery life.
