How does electric car charging affect your energy declaration?

The question of how electric car charging affects your property's energy declaration is complex and requires expert knowledge. According to Boverket rules energy use related to the operation of the building itself shall be included in the energy performance, while energy for vehicles and household appliances shall be excluded.

The difficult demarcation

The technical rule implies that:

• Energy to the vehicle (the charge itself): Not to be counted as the energy use of the building.
• Energy for the infrastructure: Electricity for lighting the charging point and separate control units is generally counted as Real Estate and must be included.

However, the practical problem arises with modern systems where control electronics, communications and load balancing are often integrated into the charging boxes. This severely limited electricity consumption risks being counted as Real Estate and thus impairing the energy rating.

ChargeNode's solution and expert advice

ChargeNode's system is designed to be energy efficient with centralized control equipment and minimal standby consumption. This minimizes the property risk of affecting the declaration.

It is important to note that dynamic load balancing is an advantage for the building's total electricity capacity and operating costs, but it does not directly affect the calculation of the building's energy use in the declaration.

Our most important advice: Always inform it energy expert which draws up the charging infrastructure declaration. Experts must make a correct and well-substantiated demarcation between the electricity excluded (vehicle energy) and the minimum electricity to be included (supporting equipment/real estate) to ensure that the declaration is accurate.
