Batteries in electric vehicles that regularly use 100-plus-kilowatts fast chargers degrade faster than those that rely primarily on slow charging, a new study suggests. Using fast chargers more frequently can cause some packs to lose nearly a quarter of their capacity in eight years, it claims. We've seen other studies suggest that fast charging has little impact on long-term battery health, so it's not a settled debate.
One of the biggest EV charging networks in the United States, EVgo, is ramping up efforts to install Tesla-style NACS cables at its stations across the country. After a successful pilot in 2025, when the company installed nearly 100 NACS connectors across 22 metropolitan areas, the charging network wants to supercharge the deployment this year, with more than 500 NACS connectors set to go online by the end of 2026 at its 350-kilowatt-capable stations.
