An electric car in the Netherlands uses around 300 Watt on average over a year. That's not a lot. The grid challenges arise because people like to charge them fast. 11 kW in a residential street is a lot. And so is 150-400 kW at a fast charging station.
@Sustainable2050 Charging when parked overnight at a slow rate is no problem for the grid. But many cars are parked on the street (in space that should be available for cycling etc).
@Sustainable2050 it depends if something is a lot or not in terms of charging. Location and time are relevant. The system needs to be more dynamic: lots of sun or wind: charge your car. During tight times: deliver back to the grid. Batteries will be an additional gamechanger. The first fast chargers combined with a battery pack are already in use..
@Sustainable2050 300 kW a year? 300 Watt sounds off.
@fschaap @Sustainable2050 About 2500kWh a year divided by 8760 hours is 285Wh. About right.
@Sustainable2050 KwH? That even seems low.
@tmstreet No, Watt. Times 8,760 hours per year.
@Sustainable2050 We need to charge the car in the daytime in the suburbs to pull the grid voltages down. Frequently seeing 250+ in my cul-de-sac.
@Sustainable2050 Source, please?
@franciswashere Own estimates. 300 W = 2,600 kWh in 8,760 hours. The charger capacities are typical values here.
