Question 1

What's the difference between Level 2 and DCFC EV chargers?

Accepted Answer

Level 2 (208/240V AC, 6–19 kW) adds 18–35 miles of range per hour and suits dwell-time parking 60+ minutes. DCFC (480V DC, 50–350 kW) adds 100–250 miles per session and suits high-turn destinations and highway corridors.

Question 2

Which EV charging hardware brands do you install?

Accepted Answer

ChargePoint, Enel X JuiceBox/JuicePump, Blink, Wallbox, EVgo (DCFC), Tritium (DCFC), ABB (DCFC), and FLO. Selection depends on networked back-end preference, warranty terms, and local utility approved-vendor lists.

Question 3

Do EV charging stations make money?

Accepted Answer

Yes when properly priced and load-managed. Level 2 stations on managed networks return 14–22% IRR over a 10-year horizon. DCFC stations return 9–18% IRR depending on utilization and demand charge management.

Question 4

What permits are needed for EV charging installation?

Accepted Answer

Electrical permit (always), site work permit if trenching exceeds 50 LF, utility interconnection approval (always for DCFC, sometimes for Level 2 over 80 amps), and fire marshal review for indoor garage installations.

Question 5

How long do EV charging stations last?

Accepted Answer

Level 2 hardware: 8–12 years average lifespan with networked uptime SLA. DCFC hardware: 6–10 years given thermal cycling and high amperage stress. Software and back-end network are upgraded continuously and do not have a defined replacement cycle.
