IAA Mobility 2021: iONiX introduces DC charging station for Urban Charging
In a collaboration, the electrical engineering companies Bender GmbH & Co. KG, Grünberg, and Silver Atena GmbH, Munich, have introduced a series of DC wall boxes and DC charging stations with CCS connectors under the joint product brand iONiX. The two products, which can charge electric cars with 25 kW / max. 80 A or 50 kW / max. 160 A, were jointly developed by the Bender Group (Bender GmbH/ebee smart technologies) and Silver Atena, are “Made in Germany,” and are set to hit the market starting in the first quarter of 2022. The relatively moderate charging power is justified by the most urban needs, where 50 kW can draw more than enough energy in about 20 minutes during a shopping stop. Additionally, the vehicle batteries are preserved and the installation effort is lower.
Depending on the variant, the iONiX charging stations are compliant with calibration law regulations, allowing their use in public and semi-public spaces. Additionally, paying on-site with a credit card is optionally possible, the provider further advertises. Thus, the charging stations already meet the requirements of the revised Charging Station Ordinance LSV2, which will be effective from March 1, 2022.
Intelligent Distribution of Energy in Charging Parks
The core of the iONiX charging stations is a DC charging controller developed by Bender, based on the well-known AC charging controller CC613. This controller masters dynamic load management, ensuring that when multiple electric cars are charged simultaneously, the available energy is distributed intelligently and efficiently, preventing the power grid from collapsing. All AC and DC charging stations in the market could be operated in a common supply and load management network with a Bender charging controller without a superior system and across manufacturers.
This means that the charging stations are suitable for use in charging parks, parking garages, shopping centers, hotels, and airports. A 25 kW DC wall box is also available for home use. The advantage of DC charging stations is that the energy provided no longer needs to be converted in the car, but can be delivered directly to the batteries, as the manufacturer outlines. As a result, significantly more power can generally be charged per time unit with fewer losses, making charging at a DC charging station faster and more efficient, it is further stated.
