Level 1 – Basic, slow, “trickle” charging – Residential – 120 volts AC (alternating current). Typically will take 3-7 Hours for PHEVs and 9-20 hours for EVs. Vehicles plug directly into a typical 120‐volt outlet. Your EV charger installer will evaluate the circuit to determine if upgrades or modifications to the property’s main electrical panel or circuits are required, and it should be a dedicated circuit, meaning no other appliances should use the same circuit.

Level 2 – Fast, or “quick” charging – Residential and Commercial – 240 volts AC. Typically will take 1-3 Hours for PHEVs and 4-8 Hours for EVs. Requires a charging station. Top Choice Electric will determine if upgrades or modifications to the property’s main electric panel or circuits are required.

Level 3 DC – Very fast charging – Commercial – 480 volts DC (Converts 3-phase AC to DC) or higher. Typically will take 10-20 minutes (80% charge) for PHEVs and 15-30 minutes (80% charge) for EVs. Requires more complex installation and potential electrical infrastructure upgrades.

Most electric vehicles will charge at one of the three charging levels, with commercial chargers at levels 2 and 3.
