The electrified car park

Electrified Car Park, Finland

Helen LTD is one of the largest energy companies in Finland. The company is located in Helsinki’s Käpylä district and has a parking garage with several fast-charging points for the electric cars of the staff and the company vehicle fleet.

The rapid charging of electric vehicles causes high current load peaks due to the desired charging speed. The TS HV 70 from TESVOLT permits peak load shaving, meaning it can “intercept” the load peaks that occur during rapid charging by making its stored energy available to support the process.

Helen LTD installed the outdoor version of the battery system in the car park and can now use it to operate the charging stations with a less powerful and therefore cheaper mains connection.
