By Vera EckertDrivers will want to charge their EVs at will to ensure they always have enough power, but letting suppliers do it for them overnight will prevent blackouts, says Vera EckertCarmakers around the world are pushing hard for new electricity networks to charge cars more quickly. But in Europe, some power companies and grid operators are testing a slower approach. A 15-month study of electric vehicle charging in Germany has concluded that consumers can be persuaded to accept slow overnight recharging to avoid brownouts from surges in electricity demand or costly upgrades to power grids.If millions of EVs hit the roads as governments gradually ban diesel and petrol cars, it will be a major challenge for power companies, especially in Germany, which is switching from nuclear and coal to wind and solar, less predictable sources of energy.Earlier this year, in its climate action plan, the Irish Government committed to having 936,000 EVs on the roads by 2030. The German study, in the wealthy Stuttgart suburb of Ostfildern-Ruit, has alleviated the concerns of some grid operators that too many electric vehicles (EVs) charging at peak times could cause network crashes.The engineers at Netze BW, the local grid operator that held… Read full this story
