Re: Smartphone EV trip dashboard - Android/iOS - $99

I might have misunderstood the initial ask. If you want to use your current module with an iOS device, it works. You can get the app from the App Store here: https://itunes.apple.com/us/app/powervelocity/id1220201461?mt=8 The Android version is in the PlayStore here: https://play.google.com/store/ap...

Re: Smartphone EV trip dashboard - Android/iOS - $99

Earlier versions of the module had only programming functionality. The dashboard was added some time in Sept of this year. So, depending on when you got the module, it may or may not have the dashboard. All current modules have the dashboard functionality. I don't make programming only modules anymo...

Re: 100+ Miles of Fun per Charge: 5.1kWh batt, 20kw capable

Well, first of all, 100 miles does not equal 100 km. It's at least 160 km. The estimate was made based on an assumption of 50 watt hours consumed per mile which is doable at the given weight and speeds of 30-40 mph on flat. This is all electric. You will do better than that with some pedaling. OK, l...

Re: PowerVelocity controller review

I never mentioned the risk of FETs failing due to inconsistent supply. It's rather consistent and comes form a single supplier. I did mention that there may be just bad mosfets in batches and that's why I warrant controllers against defects. I have repaired a few (not really many) controllers free o...

Re: Smartphone EV trip dashboard - Android/iOS - $99

That will work. Additional controller models will appear on the website soon. So if I wanted the 12F with the dashboard (I’m assuming reading the threads all tour controllers are Bluetooth programmable) how do I order one, there’s no such beast on the website. Do I sent you a message asking for what...

I am looking into getting MOSFETs directly from the manufacturer. That would help minimize mismatch and low quality parts, wouldn't it?

Since a few people asked, here is a quick demo of the dashboard in action. There some debug data added in the right upper corner - it's taken out in the production release of the app.

Re: Smartphone EV trip dashboard - Android/iOS - $99

Wh as the measure of energy and wh/mi or wh/km as a measure of efficiency are pretty much standard on all production EVs I've seen. Ah/mile makes no sense outside of a specific vehicle and should be outlawed (joking). Now, estimating energy left (or, even better, range left) is not a trivial task. T...

In most US states, having proper lights and tires makes your performance ebike registerable as a moped. Wear a proper helmet and carry insurance, and your bike is magically legal.

What voltage and current are you running? If less than 120v, I'd recommend a controller with toshiba mosfets or AOT290 if less than 100v.

So, it will be just a matter of documenting the communication protocol and implementing it in the app;. I might get to that a bit later. PV app calculates Ah based on the current consumed in every single moment and then adding it all up. But I don't like using Ah as a power capacity metric because i...

Re: Smartphone EV trip dashboard - Android/iOS - $99

The dashboard is designed to take current readings from shunt, voltage from battery positive, speed from hall sensors, and temperature from a thermoresitor. So, making it work would be as simple as soldering a few wires. I haven't looked at Bafang protocol but if's just a serial data stream, even no...

Re: PowerVelocity controller review

This may happen to pretty much any mosfet due to variation in quality of mosfets, but that's an exception rather than a rule. For that reason, I warrant all controllers against this and replace popped mosfets for no charge (unless there is a obvious sign of abuse). After replacement, this normally d...
