The charging power of battery-powered cars continues to increase with newer models. Most cars today charge with 7 to 22 kW AC, but there are also newer models that charge with over 300 kW. Despite equally large batteries, this shortens the charging time and increases the attractiveness of the green mobility vehicle.

The charging capacity of battery-powered cars continues to increase, so that newer models can charge with over 300 kW. This shortens the charging time and makes green mobility more attractive.

AXSOL Energy Container Solutions Batteriespeicher für die Ladeinfrastruktur Mega Charger Elektromobilität

With the AXSOL Mega Charger, AXSOL presents its own modular solution for flexibilising the charging infrastructure for e-mobility. The charging electronics are simply integrated into an AXSOL Energy Container Solutions container with its battery storage modules. The battery storage modules buffer the power from the grid and ensure that the desired charging power is available for all connected charging columns at any time without burdening the grid.

The power from low-voltage networks is often not sufficient, especially with larger charging stations (e.g. in vehicle fleets or company car parks), to charge all electric cars with the desired power. The result is time-consuming loading processes. The AMC can be used here as “buffer” storage and thus supply all charging points with the desired power without increasing the power consumption from the grid. Under certain circumstances, this can also lead to additional savings due to a lower performance price in the electricity bill.

More and more companies are producing green electricity through their own photovoltaic systems. In order to improve your own climate balance, your own electric vehicle fleet can be charged with this electricity. To ensure that emission-free energy is also available when there is little sun, the AMC are suitable for temporarily storing excess solar energy.

In order to avoid power peaks and the resulting higher costs, it can make sense to only make the full charging power available to your own fleet during certain time windows. The AMC offer a corresponding control that can make the charging process even more efficient.

The control of the AMC allows specific charging stations to be specified, whose performance is preferably kept high in the event of bottlenecks. For example, charging stations specially designated for customers can be prioritized.

The volatility of the transmission and distribution grids will continue to increase in the coming years due to the shutdown of traditional power plants and the delayed expansion of renewable energies. As a result, power outages will become increasingly common. In order to charge electric vehicles even if the mains power supply is interrupted, the AMC can be used as an emergency power storage unit.

In the power grid of the future, e-cars will not only be seen as part of the electricity demand, but also as a temporary storage facility and thus part of the supply thanks to bidirectional charging. The AMC control already provides the basis for subsequent implementation of the communication protocols required for this.

The intelligent AMC platform allows you to generate reports on the performance of the individual charging stations. This gives you a detailed insight into the respective charging processes, allows you to better understand consumption and bill the costs individually – for both public and non-public applications.
