Charging levels describe the rate at which you can charge your battery. These terms are industry standards and used as labels so you can quickly identify how powerful a specific charge Blink Charging, ChargePoint, Electrify America, EVgo, Greenlots, and SemaConnect are the mostmon network providers in the U.S. Finding Public Stations. Resources and apps like PlugShare, Chargeway, or the Alternative Fuels Data Center give real-time information on charging station locations, pricing, nearby amenities, and availability.Oct 18, 2020 · Edison originally targeted 100VDC, with the distribution at 110VDC to offset losses. The first AC supplies were originally at 110VAC to match, but other systems used 115V, 117V, 120V and 125VAC. Because of this variation, 117V was typically used as the target utilization voltage for end devices, as it's the midpoint of 110V and 125V.The reason for this is twofold. The first reason is that, generally, DC fast charging is far more expensive than regular AC charging. This is because it costs more to install and use. The second reason is because of the sheer amount of power that is pumped out of a DC charging point.
