The roads of the future are electric – EMC considerations for EV charging points

02 June 2021

New electric car models are being introduced almost daily. The market forecast for the BEV (Battery Electric Vehicle) predicts very strong growth in the coming years.

In 2018, the market share of electric cars reached approximately 2.5 percent, and the number of electric cars built worldwide rose to more than two million units for the first time. By 2030, the number is expected to increase tenfold, up to 60 percent, which will correspond to 20 million cars sold per year worldwide. Notably, around 80 percent of electric vehicle sales today are for purely electric vehicles (BEVs).

The charging infrastructure currently seems to be receiving little consideration in the rush to design and develop new electric car models. However, it is at least as important as the cars themselves.

Approximately 77,000 charging stations are required for one million electric vehicles – including 7,000 DC rapid charging stations. With 20 million cars sold per year, 140,000 DC fast-charging stations would have to be installed by 2030. This is a challenge, not only from an economic point of view, but also from a technical point of view. Electromagnetic compatibility (EMC) plays a key role in products designed for charging BEVs and HEVs (hybrid electric vehicles).
