A-Charge
PARKING × EV × NO APP.

What to decide before adding EV charging to a parking lot

A few DC stalls, or make the whole lot EV-ready? Force a membership app, or finish with a bay QR? A-Charge® is the latter — simple checkout including AC chargers, designed as a parking OS for every bay. Parking rates and how many cars come are your numbers. We do not issue a profit simulation.

First, the premise

This is not an invitation to invest

Installing chargers does not guarantee a profit. A-Charge is the intake system for a facility that has already decided to spend on bays or chargers, so it can run them at low cost. Yield is a number the owner calculates and takes responsibility for. After that decision, we help run the site cheaply.

Who this is for

Sites with longer stays benefit most from AC charging and time-based fees.

Four decisions before you buy

1. DC-only vs including AC

DC is costly and often needs a higher contracted demand. Where cars already stay (hotel, office, shopping), including AC usually balances cost and utilization. A-Charge’s wedge is simple checkout that includes AC.

2. Membership app vs no app

Apps and sign-ups lose tourists and first-time visitors. A-Charge: bay QR → rates → card / Apple Pay / Google Pay (NO APP.). If you already have a facility app, queueing can optionally plug into the RightOS public API.

3. A few stalls vs every bay

A small DC corner is a “charging spot.” As a parking OS, bays with and without chargers share the same intake and checkout — including timed parking for gasoline cars. Sales are the guests who already come to this site, not an EV-adoption forecast we write.

4. Whose brand is on the customer screen?

Drivers need your facility name. Logo, name, and colors can sit on the facility side; OS, payments, and OCPP stay A-Charge — white-label. Not a swap for large membership-app networks. See the white-label page. →

How to read costs (not a guarantee)

You set parking rates; session counts are this site’s guests. We do not issue a profit simulation. Cost ballpark only:

Rollout steps

1 Consult

Share use case, power intake, and target ports. Installation by I-S3 (and partners).

2 Design

Rates, bay QR, load-share cap. You can start with time billing on bays without chargers.

3 Connect

Attach chargers over OCPP; place bay QR stickers.

4 Operate

Adjust time-band rates and add ports later. Cloud-side monitoring continues.

Subsidies

National and local EV charger subsidies depend on facility type, year, and equipment rules (e.g. OCPP). We do not guarantee approval or amounts. I-S3 helps sort eligibility against site conditions.

Vs a single home charger

One residential or small-office install: I-S3 (i-s3.com/ev). Multi-bay billing and operations: A-Charge (this guide and /owners).

We're going with A-Charge.

Start on the owners page — a conversation is enough.
