Electric vehicles (EVs) are becoming more popular and diverse, but they still face a major challenge: how to charge quickly and conveniently. Different EVs use different charging connectors, which can limit the availability and compatibility of charging stations. To address this issue, a new charging connector standard has emerged: the North American Charging Standard (NACS).
The North American Charging Standard (NACS),currently being standardized as SAE J3400, is an electric vehicle charging connector system developed by Tesla, Inc. It has been used on all North American market Tesla vehicles since 2012 and was opened for use to other manufacturers in November 2022. NACS is also known as the Tesla charging standard, as it was originally a proprietary design by Tesla.
NACS is a compact and versatile connector that can support both alternating current (AC) and direct current (DC) charging. With AC charging, NACS can provide up to 80 amps at 240 volts, which is suitable for residential and public level 2 charging stations. With DC Fast Charging, NACS can provide up to 500 amps at up to 1000 volts, which is comparable to the Combined Charging System (CCS) standard. NACS can also communicate with the charging station and the vehicle to adjust the charging power and state.
