A 50 kW charger used for 45 minutes delivers about 37 kWh, roughly 110 to 130 miles of range at 3 to 3.5 miles per kWh; efficiency varies by vehicle. NYSERDA states that Level 2 charging typically adds about 25 miles of range per hour.","The car limits the rate as much as the charger does. Many EVs accept only 7 to 11.5 kW on AC, so a 19.2 kW Level 2 unit seldom delivers its full rating. On DC, charging power tapers as the battery fills, usually above about 60 to 80% state of charge, and it is lower in cold weather. Average session power therefore sits well below the nameplate figure, and planning should use the vehicle's specifications, not the charger's.","A 350 kW charger costs far more per port, usually requires 480 V three-phase service and exposes the site to large demand charges. Many NYC commercial buildings have 120\u002F208 V service, so high-power DC can mean a new service or a transformer. It also shortens the visit, which is the opposite of what most retail hosts want. For most businesses, two to four DC units of 60 to 120 kW with power sharing serve more customers at lower cost. Level 2 is inexpensive per port and adds little to peak demand; DC is expensive per port and carries the demand charge exposure explained in [our guide to demand charges](\u002Fguides\u002Fev-charger-demand-charges-con-edison-pseg-li) in Con Edison and PSEG Long Island territory.

Under [Handbook 44 Section 3.40](https:\u002F\u002Fwww.nist.gov\u002Fsystem\u002Ffiles\u002Fdocuments\u002F2025\u002F12\u002F30\u002F3-40-26-HB44-20251210.pdf), AC charging equipment must be accurate to within 1% at acceptance and 2% in service. DC equipment placed in service before January 1, 2025 is exempt from those tolerances until January 1, 2028; DC chargers installed now must meet the DC accuracy classes. The New York State Department of Agriculture and Markets, which enforces these rules through its Bureau of Weights and Measures, requires that electricity sold as vehicle fuel be billed by the kWh, that the unit price be displayed, and that receipts show the energy delivered, the unit price and any separate fees (per [its FAQ dated March 3, 2026](https:\u002F\u002Fagriculture.ny.gov\u002Ffrequently-asked-questions-electric-vehicle-supply-equipment-industry-members)).","Free charging at a busy location attracts all-day parkers.

Operable parts, including the card reader and the connector release, should be no higher than 48 inches and on an accessible route. The ADA standards do not yet set a number of accessible chargers; a reasonable number is required, and the Access Board plans a rulemaking on the minimum. The guidance describes a use-last approach, in which signs ask other drivers to use the accessible charger last, rather than reserving it.
