What is the voltage requirement for the electric vehicle supply equipment to function properly indoors?

The voltage requirement for electric vehicle supply equipment (EVSE) to function properly indoors is 240V. This is the standard voltage level that meets the needs of most electric vehicle charging systems designed for residential and commercial applications.

Using 240V allows for efficient charging of electric vehicles, enabling faster charging times compared to lower voltages such as 120V. This voltage is capable of supporting the power levels necessary for charging electric vehicles effectively, thus ensuring optimal performance and safety.

While other voltage levels such as 120V may be available for basic charging needs, they typically result in considerably longer charging times and are not suitable for the faster charging requirements of most electric vehicles. Higher voltages like 480V are generally reserved for industrial applications and are not necessary or practical for residential indoor charging setups. Therefore, 240V is the appropriate choice for providing the necessary power to EVSE indoors.
