Shared DC charging

Purpose and goal: ** Denna text är maskinöversatt **

There are several challenges with DC charging in a street environment, the most common of which is that the person who parks has to move the car so that congestion charges are not imposed on the customer, as they block the hardware for other drivers, and a DC charger is expensive to purchase.

In this pilot, ChargeNode has successfully tested to build shared DC charging for street environment. By several cars sharing a DC charger, we minimize ground work while ensuring that all electric cars can charge at full power. Expected results and effects: ** Denna text är maskinöversatt **

Technically we have solved a number of difficult issues with switching both DC current and the type of ISO15118 communication exchanged between car and charger. Approach and implementation: ** Denna text är maskinöversatt **

ChargeNode has operated this as a pure development project with prototype engineering first in the lab, then mounting it in a public parking lot near ChargeNode´s office in Gothenburg, as it was difficult to get access to the originally intended parking in Stockholm.

The hardware works and runs daily in our development environment, where authorized persons can charge their cars in a semi-public setup.
