For a gym, a cafe or a restaurant, the design unit is the visit. A customer stays for a workout, a coffee or a meal, and the charger can only add what its rate allows in that time — at Level 2 rates, roughly 10–20 miles of range per hour by U.S. DOT figures. So the buying questions are not maximum power: they are how many bays turn over, how simply a session starts, and whether charging is free or paid — the venue’s own decision.
Key Takeaways
- Design around the visit: observe your own dwell and peak, then match power and bay count to it.
- At Level 2 rates a short stay earns a top-up, so turnover beats maximum power.
- Free versus paid precedes the hardware; billing runs on the venue’s operator platform, not the charger.
- More AC bays usually beat one faster unit where cars arrive together.
Start With the Dwell You Actually See
No published statistic knows your car park. Watch it for a few ordinary weeks and sort visits the way your own operation does — a workout, a coffee stop, a sit-down meal — noting how long cars stay and when bays fill. That observation, not an industry average, sets the design: a one-hour visit and a three-hour visit are different products.
| Venue | The visit, as the venue observes it | What Level 2 adds in that visit | The decision it drives |
|---|---|---|---|
| Gym | A workout-length stay, peaking before and after work | A useful top-up per visit; regulars return weekly | Several AC bays over one fast unit; member access beats speed |
| Cafe | The shortest dwell of the three; high turnover across the day | A small top-up per stop | Bay turnover and a session that starts in seconds; one or two bays, plainly signed |
| Restaurant | A meal-length stay, concentrated in the evening | A solid top-up across the meal | Enough bays for the dinner peak, not the daily average |
Power Class, Honestly Placed
DC fast charging belongs to a different dwell: the U.S. DOT puts the DC fast band at 50–350 kW, built for stops measured in minutes. Between that band and Level 2 sits compact DC at about 20–30 kW, for a venue whose observed dwell is genuinely short and whose supply can carry it — a licensed electrician confirms the supply, breakers sized at 125% under the NEC rule. Most of these car parks gain more from extra AC bays than from one faster unit: the evening’s second car cannot use a charger the first car holds. For U.S. cost scale, DOE figures put public Level 2 at about $3,500 equipment plus $2,500 installation per connector, against $38,000–$90,000 of equipment for DC fast charging. The visitor-facing case sits in our guide to EV charging for restaurants and retail.
Access, and the Free-or-Paid Decision
Free amenity charging needs the simplest possible start and a way to stop one car camping on the bay all day. Paid charging needs user identification and session records; billing runs on the operator platform the venue appoints — no charger in this range takes payment by itself, and a station screen is a display, not a payment terminal. Members-only at a gym follows the same logic: the venue administers the charger’s stated access method — RFID card or app, as listed. Sign the policy at the bay: who may charge, for how long, what it costs.
Hardware for Short-Stay Venues
For per-user records, the EV-ACT3204PE 22 kW three-phase wallbox (tethered Type 2 cable, RFID and app access, IP66, CE) gives a controlled point. Where two bays share one position, the EV-AC03201T dual-connector AC station runs two Type 2 connectors sharing up to 43 kW (22 kW per connector), OCPP 1.6J, RFID, IP54. Both record sessions per user; neither bills a customer by itself — the venue’s platform arrangement does that. EVDANCE is a Shenzhen manufacturer founded in 2011 with a 3-year standard warranty.

Frequently Asked Questions
Is DC fast charging a better choice for a cafe?
Only if your observed dwell is genuinely short and your supply and budget carry it. Check the class: corridor DC fast charging runs at 50–350 kW; compact DC at about 20–30 kW is the realistic middle option for a small site. For most cafes, a second AC bay serves more customers per day.
Should a gym or restaurant charge customers for charging?
That is the venue’s policy decision, not a hardware feature. Free charging buys goodwill and needs turnover rules; paid charging needs an operator platform for billing and session records. Choose before you buy — the access control you need follows from the choice.
How many charging bays does a small venue need?
As many as your observed peak justifies: count the EVs in your car park on the busiest evening or class change, and start there. A second phase can follow the first phase’s records.
