A-Charge®FOR OWNERS
A-Charge® is not a “few DC stalls + heavy membership app” network. It is a parking OS built for simple checkout—including ordinary AC chargers—across every bay. Payments, queueing, power sharing, and monitoring are one design on Google Cloud — the opposite of spreadsheets and DIY. Easy to start whether utilization is low today or rising tomorrow.
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.

A-Charge®CAMPAIGN
NO LOCKS. NO CONES.
No locks. No barriers.
Every bay, time-based fees for any vehicle, anonymous smart queuing—leave cones and padlocks behind.
Campaign article & video →Share the long-form clips matched to your language before the brochure—why lots get chosen, the guest journey, and no locks/cones. Other languages, Shorts, and the classic ~90s intro are in the video library.

Guests charge during their stay. No patience for installing an app—QR gets them started in seconds.
Charge while shopping. High share of one-time visitors means “no registration” protects conversion.
Whole-lot by design—so the same QR checkout can extend beyond EVs to general timed parking, with optional cameras for bay occupancy visibility. Parking DX, not a charging corner.
High first-use friction leaves chargers idle.
Not a rapid-only membership app. Ordinary AC chargers too—no install, no account. Card / Apple Pay / Google Pay. UI in 20 languages.
Most of the lot stays on another system—or stays empty of charging.
Same QR intake and checkout for bays with or without chargers—grow as a parking OS.
Tariffs and metering get hard to explain.
Clearer revenue planning; less tied to electricity price swings.
Intake, billing, payments, queueing, power sharing, and monitoring, designed as one system from day one for fleet-scale operation.
If another billing app or CSMS becomes unavailable, OCPP 1.6 / 2.0.1 hardware can often reconnect to A-Charge without replacing the chargers (the central system accepts both). After model checks, set the backend URL and resume operations. See the retrofit section on the owners page.
Everything is per charger, per month. Tiered rates keep low-utilization months from feeling heavy.
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.
Set a site power cap and we automatically share load so simultaneous charging stays within contract demand. You don’t have to size ports only by peak kW—multiple chargers can run together while staying inside the limit, making it easier to grow capacity.
Drivers still need no dedicated app (NO APP.). If you already run a membership, facility, or OEM app, you can add anonymous queue / usage rights via the RightOS public API—keep your front door, add the rights layer. This is not an eMSP roaming replacement, and we do not lead with API-first nationwide rollouts. The core path remains QR intake, time-based parking fees, and OCPP.
Tell us bay count, power capacity, and any existing chargers—we’ll propose a fit. Share the intro video and this page, then just ask for materials.
