Electric Vehicle Supply Equipment


Electric vehicle supply equipment is used to charge electric vehicles.


Our recommended standard for electric vehicle supply equipment is based on ENERGY STAR Version 1.0, which took effect in December 2016. The ENERGY STAR specification applies to Level 1 chargers (which operate at 120 V), Level 2 chargers (which operate at 208 or 240 V), and combined chargers.


Electric vehicle supply equipment meeting ENERGY STAR Version 1.0 use about 40% less energy than standard models in standby mode. In 2020, 20% of shipments of electric vehicle supply equipment were ENERGY STAR qualified.
