A-Charge®CAMPAIGN
Onsen, bowling alleys, golf driving ranges, and fitness clubs all keep guests for hours — a natural fit for AC charging. Yet major chains have moved first, leaving independents and regional chains with a real gap. Because A-Charge puts the same QR on every bay, charger or not, the whole lot becomes one time-billed system.
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.
The same QR goes on every bay, so there's no separate operation for bays with and without chargers — the whole lot becomes one front desk.
No app, no membership (NO APP.). Even a first-time visitor scans the QR and is charging within seconds.
Start without installing gates, flaps, cones, or padlocks (NO LOCKS. NO CONES.).
Facilities with parking that can host multiple AC chargers, in long-stay businesses (hotels, ryokan, retail, offices). As a model case, facilities willing to let us publish operational results are prioritized.
The full per-charger package (charger hardware, standard installation work, and the initial system setup fee) is free for up to 2 units. There is no cap on the total number of chargers—from the 3rd unit on, add as many as you like under standard terms. Chargers installed free of charge under this campaign (up to 2 units) are removed free of charge, and the site restored to its original condition, if it does not work out (terms are stated in the written agreement; units added from the 3rd onward are not covered).
The first two sites are featured as case studies on I-S3's official sites (a-charge.jp, i-s3.com) and YouTube channel, presented as the first facilities in their area to offer this convenience. We also provide photos and copy you can use in your own announcements.
Limited to the first 2 applicants. We may decline if the site survey finds conditions unsuitable.
A-Charge itself is a nationwide service. Because this campaign involves charger installation work, we prioritize applications from Kanto and Koshinetsu (centered on Gunma / Takasaki), where our in-house installation coverage is densest—but consultation is available anywhere in Japan.
Paid bays without chargers get QR codes first. They start earning time-based parking fees on the same OS, and chargers can be added flexibly later.
Blocking a bay with cones, chains, or a lock, or requiring drivers to check in at the front desk before they can start, goes against A-Charge's core promise (NO APP. NO LOCKS. NO CONES.) and is strictly prohibited. If this is found happening, it is treated as a breach and subject to a contractual penalty. Every bay must always stay in a state where a driver can start immediately just by scanning the QR.
Card and payment fees are paid by I-S3. This campaign does not guarantee feasibility, unit count, cost recovery, or operational results. Terms may be adjusted or declined depending on site survey, power capacity, and facility conditions.
Not a few DC stalls, and not an EV-only corner. Bays with chargers and bays without run on the same single OS. Very few parking lots operate this combination today.
Charging or parking-only, drivers just scan the bay QR—intake through checkout (A-Charge. Just scan.). You set the parking rate. How many cars come is this site’s guests.
No account, no app for drivers (NO APP.). When it gets busy, anonymous digital tickets handle turns and rights.
Start without installing gates, flap locks, cones, or padlocks (NO LOCKS. NO CONES.). The whole lot becomes billable while physical construction stays light.
"First model site" can sound like being a test bench. In practice, what changes on your side is far narrower than it sounds: starting A-Charge is not a construction project, but a connection that links your chargers to the cloud.
A cloud-side connection setting on a PC that links the chargers to A-Charge — plus QR signs at the bays. That is all.
Because connecting involves no physical construction, going back to your current operation is just as easy if it does not fit. Chargers installed under this campaign are also removed free of charge, and the site restored to its original condition, if it does not work out.
After installation, the system fee is the standard tiered rate—everything per charger, per month. Low-utilization months stay light on fixed costs.
Outside Japan, the same tiers can be set in local currency near those yen levels—e.g. about US$14 / NT$400 for the flat starting tier (examples; quoted per market). Card fees are paid by I-S3. Setup is ¥100,000 per charger in Japan (AC/DC). Construction quoted separately.
Look at I-S3’s electrical construction and monitoring systems—not at how many A-Charge billing sites exist yet. A-Charge is the parking OS built on that work.
High-voltage interconnection, self-consumption, repowering, and O&M. Food-plant ~200 kW self-consumption and high-voltage ~500 kW upgrades: live sites, multiple stakeholders, electrical work done safely.
Remote solar monitoring and 30-minute demand sizing, our own RightOS anonymous queue, and an OCPP 1.6 / 2.0.1 central system with load sharing under the site power cap. Not spreadsheets bolted on after the fact.
Hundreds of jobs centered on Gunma. Mostly AC (Tesla Wall Connector and similar); over 99.9% of residential jobs finish the same day. Eleven prefectures by our own visits, six in Kansai via partners (17 total). We also design turnkey facility packages that include 50 kW / 120 kW DC.
Billing sites under the A-Charge name are still being added. Installing, isolating, monitoring, and reconnecting electrical plant is I-S3’s core work.
