NO CHARGE: Duke Energy Warns Customers to Not Use EV Charging Stations After Fire Involving Siemens Charger and Chevy Volt. “After a house fire in Mooresville, NC which started in the home’s garage was traced the the area near a charging station for an electric vehicle, WSOC-TV reported that Duke Energy, which installed the Siemens built charging station, has warned customers to not use similar units while the investigation into the fire proceeds. When fire investigators went through the burned out garage, they found a Chevy Volt plugged into the 240 volt station, the second garage fire reportedly involving a Volt. Since it was not the only electrical appliance plugged in that area of the garage, the charging station may not be at fault.”
