Would you charge your electric vehicle overnight to save money on power?

Siemens released a study forecasting that European cities will need almost €25 billion in EV charging infrastructure investment by 2030. The study analysed 64 cities across the 27 EU countries, Iceland, Liechtenstein and Norway, and found smart charging could cut that bill by 40%.

Why it matters

As the number of electric vehicles is projected to grow on average 3.8 times, grid capacity in cities becomes a practical question for drivers and property owners alike. Smart charging, which shifts electricity use to low-demand hours such as the middle of the night, could meaningfully lower the cost burden that would otherwise be passed on through infrastructure spending.

The study estimates almost €25 billion in charging infrastructure investment is needed by 2030, with €24.7 billion of that for electricity distribution grid upgrades. Smart charging could lower the total investment bill by €10.6 billion, a 40% reduction.

The players

Siemens

German industrial conglomerate whose smart-grid and energy-management technology lines make it a central voice on how cities can integrate EV charging into existing electricity networks.

ACEA

The European Automobile Manufacturers' Association, the trade group representing major car makers, which co-commissioned the study on EV charging needs.

ChargeUp

The European EV charging industry association, which co-commissioned the study and represents charge-point operators and related firms.

The details

The study was commissioned for the European EV charging industry association ChargeUp, the auto manufacturers group ACEA and the partnering group EIT Urban Mobility. Smart meters would allow vehicles to charge when existing electricity demand is lowest, such as in the middle of the night, easing pressure on the grid at peak hours. The greatest investment need is for low-voltage grid upgrades, and requirements are highest in Germany, followed by Norway, Belgium and the Netherlands because of their significant existing EV fleets.

The Home Front

The European Commission has proposed promoting predictable, cheaper off-peak electricity prices across the EU, which aligns with the study's finding that night-time charging lowers grid costs. Together these point toward home and workplace charging being priced and scheduled around grid demand rather than run at any hour.

If you own or plan to install a home EV charger, ask your electrician whether your existing supply can handle overnight charging and whether a smart charger with scheduling is suitable. Consider setting your charger to start during off-peak hours if your electricity tariff offers cheaper night-time rates.

The takeaway

Scheduling EV charging for low-demand hours is one of the cheapest ways to reduce the grid investment that would otherwise be passed on to households. Check whether your electricity provider offers off-peak tariffs, and have a licensed electrician confirm any upgrades before adding a home charger.
