• **Level 1 Charging**

This is the slowest charging way and the simplest because no additional infrastructure is needed, and any wall outlet can be used. In the US, a standard 120 V/15 A wall outlet is used for Level 1. It is available only as an on-board charger. Although its cost is less than other charging levels, the EV needs a long time to be fully charged. Due to its low power rating, this charging level has the lowest impacts on distribution systems.
