Charging management in the underground car park
More and more electric cars are being parked in underground car parks. Landlords and property owners are faced with the question of how to deal with this - what charging infrastructure they should provide. Together with SCS, EKZ has developed a manufacturer-independent charging management system.
Electric cars charge with around 30 A. A typical domestic connection for an apartment block is designed for 500 A – 400 A of which is reserved for the building. The 100 A that remain for the charging infrastructure in the underground car park are already at their limit with three electric cars. And it is only a matter of time before the majority of cars are running on electricity. Property owners are therefore faced with the question of how to meet tenant demand for charging stations.
A new, more powerful house connection is the most expensive solution – for both the factory and the homeowner. This is why charging management is usually used. After all, not every car has to be charged at the same time. And hardly any vehicle uses its full range every day – the batteries are rarely completely empty. Most manufacturers of charging stations therefore offer a charging management system that decides which car is charged when.
It becomes difficult when charging stations from different manufacturers are installed in the same underground car park. Which will probably be the case in many locations over time. EKZ has therefore developed a charging management system together with SCS that is based on the manufacturer-independent OCPP protocol. Martin Baldinger from EKZ reports on his experiences with the 400 underground car parks that are now working with the system. Marcel Frei from SCS talks about the challenges faced during development and how the project is now being continued so that, for example, cars can be charged with solar power, individual vehicles can be given priority if users are willing to pay for them, or a connection to the house installation can be established so that the underground car park can draw exactly as much power as the house connection can provide.
Following the presentations, all participants are cordially invited to an aperitif. The event is open to all interested parties and will also be broadcast online.
