Not a few DC stalls in the corner. A parking OS built to roll out across the whole lot — including ordinary AC chargers — with one simple QR checkout. OCPP chargers and bay stickers are enough to start.

Watch first (about 90 seconds)
AC chargers × every bay × simple checkout. Share this clip before the brochure. Other languages, Shorts, and the script are on the video page.
Not a heavy membership app built only for rapid chargers. Drivers scan the bay QR — card / Apple Pay / Google Pay. First-time guests start in seconds; 20 languages keep inbound visitors.

Built for every parking space
Not “a few EV stalls in the corner.” Same QR intake and payment for bays with or without chargers. With optional cameras, timed parking for gasoline cars rides the same flow.
🖥️
Almost no operational workload
Chargers register themselves when connected. Pricing, monitoring, and refunds stay on the web dashboard. No on-site staff; collection finishes through online payment.
⚡
Gentle on your electrical equipment
Set the site power cap and output is shared automatically so simultaneous charging stays within contract demand — which pairs well with rolling out more AC ports across the lot.

Go deeper: why owners choose A-Charge
The AC × every-bay × simple-checkout wedge, utilization-linked fees, and load sharing—on one page.
Billing is based on parking time, not on kWh delivered, so revenue is predictable and unaffected by electricity price fluctuations.
Parking and charging rates can be set freely per facility and per time period. Switching from free (promotional) to paid operation takes effect instantly from the web.
Settlement is calculated automatically from actual usage time at the end of each session. Even if a user leaves without checking out, billing is automatic with an upper limit, so you never miss revenue.
At busy facilities, the anonymous queue & reservation feature (no personal data collected) improves turnover.
Optional camera integration for bay occupancy visibility is currently in field testing and will roll out progressively (unauthorized-parking detection is also under development).
Whole-lot by design: the same QR intake and payment apply to bays without chargers. With optional cameras, that becomes timed parking for all vehicles, including gasoline cars.
Trust & security
Card data never touches our servers. Payments use Stripe Hosted Checkout; A-Charge does not collect or store PAN, CVV, or expiry (we keep card data out of our own environment).
Traffic is protected with HTTPS (TLS). Responses include HSTS, nosniff, Referrer-Policy and related security headers.
Secrets for Stripe, OCPP, and encryption keys are stored in Google Secret Manager — never hard-coded.
Sensitive owner data such as bank account numbers is encrypted at the application layer before storage.
No user accounts. Anonymous queues. Arrival location is checked but not stored. Admin tools are limited to our corporate domain.
All fees are per charger, per month. To keep low-utilization sites viable, the fee is a flat ~US$14 while monthly sales stay within about US$70. Above that, the rate declines with sales: ~20% from just over US$70 up to about US$170, 15% from about US$170, and 10% from about US$340. The same rule works whether utilization is still low or rising.
Card / Apple Pay / Google Pay processing fees are billed separately from the system fee (at the payment provider's rates).
The one-time system setup fee is JPY 100,000 per charger (both fast and standard chargers). Installation work is quoted separately based on site conditions. We can also supply chargers and arrange installation work for you.
This fee rule is the same worldwide. The figures above are approximate US-dollar equivalents; actual contracts and settlement use the currency of the country where the charger is installed.
Each charger is registered with its installation site (facility location) and currency. Parking and charging rates for users are also set and displayed in the installation country's currency.
