Question 1

How many EV stalls should a parking lot have?

Accepted Answer

2026 best practice is 8–12% of total stalls EV-equipped at install with conduit run to an additional 18–28%. Multifamily and workplace properties skew higher; transient retail skews lower.

Question 2

Should EV stalls be free or paid?

Accepted Answer

Paid in almost every commercial setting. Free EV charging cannibalizes premium parking revenue, attracts non-customer charging, and creates abuse via long-dwell vehicles. Pricing should cover energy + demand charges + 18–32% margin.

Question 3

What's an idle fee and when should it apply?

Accepted Answer

An idle fee charges EV drivers per minute after their charging session completes but before they vacate the stall. Standard implementation is $0.40–$1.20 per minute starting 10 minutes after session end. Cuts stall-hogging by 60–80%.

Question 4

What uptime should EV chargers maintain?

Accepted Answer

Industry SLA is 97% uptime. We operate to 99.2% on managed networks via daily remote diagnostics, 4-hour onsite response for hardware faults, and quarterly preventive maintenance.

Question 5

How is EV parking different from regular parking?

Accepted Answer

Longer dwell times (45–180 minutes vs 12–35 for retail), higher per-vehicle revenue ($4–$12 vs $1.80–$4.50), and dedicated enforcement against gas vehicles in EV-only stalls (idle fee + tow program).
