The North American Charging System (NACS), standardized as SAE J3400, is an electric vehicle (EV) charging connector standard maintained by SAE International. [1] Developed by Tesla, Inc., it has been used by all North American market Tesla vehicles since 2021 and was opened for use by other manufacturers in November 2022.
Approximately 10 years prior, the Tesla in-car range estimation algorithm was adjusted to provide an optimistic forecast when the battery state of charge was greater than 50%, switching to a more realistic forecast below 50%, and included an additional "safety buffer" range of approximately 15 mi (24 km) when the state of charge was 0%.

Tesla also began rolling out V4 chargers in North America in October 2023 with integrated "Magic Dock" CCS1 adapters and payment terminals for charging vehicles without an adapter or the Tesla App. [23] [24] As of May 2024, only 17 V4 chargers have been deployed in North America. Only six of these allow use of the magic dock with only 2 of ...
SAE J1772, also known as a J plug or Type 1 connector after its international standard, IEC 62196 Type 1, is a North American standard for electrical connectors for electric vehicles maintained by SAE International under the formal title "SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler".
A charging station, also known as a charge point, chargepoint, or electric vehicle supply equipment (EVSE), is a power supply device that supplies electrical power for recharging plug-in electric vehicles (including battery electric vehicles, electric trucks, electric buses, neighborhood electric vehicles, and plug-in hybrid vehicles).
Battery chargers may be strictly manual, or may include controls for time and charging voltage. Battery chargers that apply a high voltage (for example, more than 14.4 volts on a 12-volt nominal system) will result in the emission of hydrogen gas from the battery, which may damage it or create an explosion risk.
These symptoms are often mistaken for a virus such as influenza or other illnesses such as food poisoning or gastroenteritis. [21] Headache is the most common symptom of acute carbon monoxide poisoning; it is often described as dull, frontal, and continuous. [ 30 ]
