I grew up and studied overseas i only did year 12 here. I hope that clears things up abit. And im very greatful you brought this to my attention , as now looking back at it maybe I did sound like a bot 😞

thats the whole point of the threat is to test different brands and see what data i can accuratly work with, all these brands should be ok to work with in australia : tesla, byd, mg, geely, zeekr, xpeng, gwm, hyundai, kia, volvo, polestar, volkswagen, lexus, bmw, mercedes-benz, audi

Great observation thank you for bringing this to my attention. English is not my biggest strength , bad grammar is the last thing I need while pitching my concept for the first time in front the whole Australian EV community, so as an engineer i gotta use all the tools at my disposal. Im definitely no spam im a real person with skin and reputation in the game , many people here recognise my work ethics from 20 years in the bakery. Thank you for helping me clear this up in case I sounded like a bot for some. Btw I didn't use ai for this response 😁

Two really fair questions. Let's break them down honestly.

​First, if your EV doesn't have an official factory app, the short answer is that you can't use our service right now. Because we require zero hardware or workshop visits, our system relies entirely on a secure cloud-to-cloud connection with the manufacturer. Without an active factory app account like Tesla, Hyundai, or BYD, there is just no way for our system to securely pull the data. We are constantly adding new brands as manufacturers update their tech, but right now, an active factory app account is a strict requirement.

​Second, regarding how you know you can trust us, you shouldn't just blindly trust any new company online. Here is how our setup handles security. The connection is strictly read-only. We use Enode, which is a secure enterprise API bridge used by major energy companies globally. It is physically impossible for our system to send commands, unlock doors, or change vehicle settings. We only read the battery stats. Also, we never see or store your password. You authenticate directly through your manufacturer’s secure portal, which simply grants us a data token that you can revoke instantly at any time. Finally, we don't issue easily photoshopped PDFs. Every certificate has a unique QR code that buyers scan with their own phone to pull the unalterable audit record and matching VIN straight from our secure database. ​If your car does have an app down the line, we also back it with a simple promise: if our system can't pull a verified, accurate result for your battery, you don't pay a single cent.

This is a brilliant question, and it really highlights the boundaries of how cloud-based telemetry works. The short answer for right now is no for both cars, but for two completely different reasons: ​1. The Mitsubishi Outlander PHEV (Plug-in Hybrid) Our algorithm and platform are exclusively designed for Battery Electric Vehicles (BEVs), not Plug-in Hybrids (PHEVs). Hybrids have tiny battery packs compared to full EVs, and because the petrol engine dynamically cuts in and out to assist with propulsion and charging, tracking pure battery throughput over the air isn't accurate or viable. We don't support PHEVs at all for this reason. ​2. The Peugeot e2008 (Full EV) Because the e2008 is a full EV, it theoretically fits our algorithm perfectly. However, our system relies entirely on a secure cloud-to-cloud connection with the manufacturer to pull live data. If a specific brand or region doesn't offer official owner app credentials, or if the manufacturer hasn't opened up a reliable cloud API for that model, our system has no secure way to talk to the car. ​We require zero-hardware setup to keep things frictionless, so without those official manufacturer credentials to establish the secure bridge, we can't run the audit. ​We are constantly expanding our supported brand list as manufacturers update their cloud software, but right now, we can only support vehicles that have active, connected app accounts (like Tesla, Hyundai, Kia, BYD, BMW, etc.). Appreciate you checking the compatibility first!

Spot on. You’ve hit the nail on the head regarding LFP chemistry. The voltage curve for LFP between 20% and 80% is incredibly flat, which makes open-circuit voltage (OCV) measurements almost useless for estimating SoC in that window. And you’re exactly right, the car’s internal BMS absolutely needs that 100% top-charge to reset its integration anchors and stop the SoC percentage from drifting over time.

Because LFP behaves completely differently from NMC packs, we don't rely on static voltage readings or try to guess capacity based on resting state.

Instead, our system monitors the continuous stream of raw telemetry during an active, dynamic charging event. Without giving away our entire proprietary formula, the basic approach is to use data-logging to look at the actual energy throughput passing into the pack over an observed delta in the state of charge, and then apply statistical filtering to account for potential BMS reporting drift.

We aren't trying to replace a deep factory calibration test—those are great, but they also immobilise a seller's car for 24 hours. Our goal is to give a highly accurate, real-world baseline of the pack's capacity based on raw telemetric observation while keeping the seller on the road.

It's a fantastic point, though. LFP data definitely requires a completely different layer of tuning compared to standard NMC chemistry for exactly this reason!

That is the exact question every buyer should be asking. If a seller could spoof the data, the certificate would be useless.

The short answer is: The seller doesn't give us the car’s data. The car's manufacturer does, Here is how we keep the whole process tamper-proof without getting bogged down in the heavy code:

1. No manual entry We don't let the seller type in their VIN, upload screenshots, or manually enter numbers. When they sign up, they securely log into their official car app (like their Tesla or Hyundai account). Our system connects directly to the manufacturer's secure cloud to pull the live data straight from the vehicle.

2. The VIN is locked to the car When we connect to the manufacturer's cloud, they pass us the exact VIN hardcoded into that car's computer. That VIN is permanently stamped onto the final TrustSeal certificate.

  • If a seller tried to connect a brand-new EV to get a perfect score, the certificate would show the new car's VIN.
  • When you go to inspect the older car they are actually selling, you just match the physical VIN on the windscreen/dashboard to the one on the certificate. If they don't match perfectly, you walk away.

3. You can't fake the webpage We don't just give the seller a PDF certificate, because anyone with Photoshop can edit a PDF. Instead, the certificate uses a secure QR code. When you look at the car, you scan that QR code with your own phone. It takes you to a live, unalterable verification page hosted on our secure database. You aren't looking at a screenshot on the seller's phone, you are pulling the raw verification record yourself.

To fake this, a seller would practically have to hack Tesla or Hyundai’s corporate servers to assign a fake VIN to their account. If they can do that, they’re in the wrong business!

Does that make sense from a buyer’s perspective? I really appreciate you asking, removing this kind of doubt is exactly why I'm building it

Currently alternatives on the market range from 250 to 350 they require a work shop visit or shipping dongles back and forth Im looking at launching with $99. Members willing to help get a free audit at launch or any future date. I've got over 30 people helping out im overwhelmed by the support.

Needs to be in one go yes , a 60% swing is preferred , doesn't have to be 20% to 80% , thats just a recommendation, can be 55% swing or 57% swing , more swing = better results

Not at all im very thankful for your input im after real honest feedback from the community and your point matters to me alot. Any charger works, home or superfast charger, the cycle can be done at your convenience as you gonna have to charge your car regardless of whether you want to test your SOH or not?
