WebAug 8, 2024 · Three broad categories of EV charging infrastructure exist today: Alternate-current (AC) charging, also known as level 1 or level 2. In this system, an in-car inverter converts AC to direct current (DC), which then charges the battery at either level 1 (equivalent to a US household outlet) or level 2 (240 volts). WebIf all EV chargers sold in the U.S. met ENERGY STAR requirements, the savings in energy costs would grow to more than $17 million and 280 million pounds of greenhouse gas emissions would be avoided. The number of plug-in electric vehicles on the road in the United States is increasing. Fully electric cars produce no tailpipe emissions.
