The core truth: Most AC chargers on the market cannot read your EV’s actual battery level. Our smart charger can. It’s that straightforward.
The Industry-Wide Blind Spot That Everyone Accepts
Does your AC charger actually know how much charge your electric vehicle has left?
For 99% of AC chargers out there, the honest answer is no.
They know two things: when to start and when to stop. The SoC (State of Charge) displayed on your app is usually a cloud-based estimate — derived from historical driving patterns and charging behavior. Typical error margin: ±5% to ±10%.
For a vehicle worth tens of thousands of dollars, that level of uncertainty is simply unacceptable.
The root cause: The industry-standard communication protocol for AC charging was never designed to read battery data from the vehicle. This isn’t a failure of any single manufacturer — it’s a compromise the entire industry has lived with for years.
How We Solved It (In Plain Words)
Rather than patching an outdated protocol, we took a different technical approach — drawing from the data interaction methods used in DC fast charging and adapting them to the AC charging scenario.
The result: At the very moment charging starts, our charger completes a brief, precise handshake with your vehicle’s Battery Management System — capturing the real battery level.
Here’s the key: this handshake happens only once, at startup. Once we have the data, the charger immediately reverts to standard AC charging mode — stable, reliable, and with zero additional hardware overhead.
One Reading at Start, Precision Throughout
To be clear: we read the initial SoC at startup, not continuously in real-time.
This isn’t a limitation — it’s a deliberate engineering choice:
A charger’s primary job is to deliver power reliably, not to maintain a persistent communication link
With a real starting point, the platform’s back-end can continuously calculate the current SoC using real-time energy metering
Platform calculation logic:
Current SoC ≈ Initial SoC + (Energy Delivered ÷ Total Battery Capacity)
It’s the most reliable way to solve a complex problem — grounded in solid engineering.
What This Means for You
1. Smarter Charging, Not Guesswork
With the actual starting SoC, the charger can intelligently adjust its charging curve — gentle pre-charging at low levels, precise topping-off at high levels. Battery protection starts with knowing the real starting point.
2. Plug, Walk Away, Done
By reading the vehicle’s unique identifier, we enable local authentication. No cards. No QR codes. No app-launching. Plug in, walk away, charging begins. The DC fast-charging experience, now on AC chargers.
3. SoC You Can Actually Trust
Your app no longer shows “guesses” or “cloud-delayed estimates.” It shows a value based on real BMS data at start, dynamically updated through precise energy metering. Under time-of-use electricity pricing, you can accurately decide whether to adjust your charging schedule.
4. No Network? No Problem
Communication happens through the charging cable itself. No 4G/5G signal required. No Bluetooth pairing needed. Underground garages, remote locations — the charger works exactly the same.
Not Just Theory — Tested on Real Vehicles
These capabilities have been validated on production vehicles:
Vehicle Model Status
Ford F-150 Lightning ✅ Verified
Lucid Air ✅ Verified
Tesla Model 3/Y 🔄 In Verification
Tesla Cybertruck 🔄 Under Debug
We continuously expand our compatible vehicle list and deliver new capabilities to existing chargers through OTA (Over-The-Air) updates.
Where We Stand in the Industry
Basic Charging: On/Off Power delivery only, no data. The vast majority of AC chargers
Cloud-Connected Smart Charging: Cloud-based SoC estimates, app control; most “smart” chargers
Our Position: Initial BMS SoC reading + platform-based tracking + AutoCharge + OTA; industry-leading tier
Our benchmark isn’t ordinary AC charger manufacturers. It’s products like the Tesla Wall Connector — which enables deep vehicle-charger interaction. The difference? Tesla only serves Tesla. We serve EV owners across brands.
The Bottom Line：
Your charger should know your vehicle’s true battery level at the moment you plug in.
We made that happen. Not through guesswork. Not through cloud estimates. Through deep protocol understanding and solid engineering.
Every charge should be genuinely smart. Now it can be.
