German electricity grid is broken for fast charging says ADS-Tec

A major EV charger maker is warning that the electricity grid in Germany is unable to meet the need for more fast charging of electric vehicles

“Grid expansion is reaching its limits and cannot grow fast enough to meet the demand for a functioning charging infrastructure,” said Thomas Speidel CEO and founder of ADS-TEC Energy.

Last week, German electricity supplier Stadtwerke Oranienburg told the regulator that the upstream high-voltage grid cannot provide sufficient power for Oranienburg. “This means that the supply options in the town of Oranienburg have been exhausted,” said Peter Grabowsky, Managing Director of Stadtwerke Oranienburg. The additional capacity that has been requested for over a year has not been made available and, as a result, applications for charging infrastructure connections are no longer being approved.

“We make fast charging possible even on the undeveloped and power-limited grid,” said Speidel. “The key to this is our integrated battery storage system. It allows us to support the grid for charging at up to 320 or 300 kW. When two EVs are charged at the same time it supports each at 160 or 150 kW.”

ADS-TEC Energy, which is incorporate din Ireland and listed on the US Nasdaq, was showing its ChargeBox and ChargePost systems, each with two charging points, at the Hannover Messe this week.

The 300 kW ChargePost features two 75-inch advertising displays and the ability to feed from the battery into the vehicle and back into the grid

ADS-TEC Energy, partners and infrastructure operators face challenges in sourcing products and services from local companies would help ensure the independence of the critical grid infrastructure.

With a footprint of just 1.95 m2, the ChargePost is aimed at urban areas where the grid is limited, and expansion would be costly and time-consuming. The ChargePost supports grid connections from 22 to 87 kW and can charge EVs in just a few minutes thanks to its innovative battery storage technology. The battery also feeds energy back into the grid.

“With this technology, we can not only store renewable energy directly on site, we also make energy trading possible. Electricity is either consumed directly on a decentralized basis or traded when there is no vehicle to charge,” said  Speidel. “ChargePost is a sustainable and profitable investment that can support different business models depending on the location. Not only can you charge EVs with this system, but you can also display advertising on the two 75-inch displays, use your own low-cost PV, and participate in electricity trading.” In addition, customers can connect multiple ChargePosts to create a virtual power plant that reduces expensive grid peaks.”
