Good thinking- the high voltage is dangerous and you absolutely should get something for your investment. You could offer training sessions with materials - charge a decent amount for training Technicians to do this correctly. Like a Weekend Workshop.

What was it? Battery management module?

I agree with your notion that your charge profile does not change with battery size. Since this is more deepened on your driving then the vehicle. Almost all EVs get around 4miles/kwh. When you drive 40 miles every day - that will be 10kwh every day. No matter if you got a 20kwh battery or...

Awesome havrla! http://elektroforum.cz/viewtopic.php?f=12&t=857&start=100 Did you solve the coding issue? Full power enabled?

so there are two options. 1. You take the pack apart and add your own BMS to each cell. soldering any aftermarket BMS to the existing balance leads. 2. You get one of these: https://www.secondlife-evbatteries.com/collections/accessories/products/simp-bms Yet, you home system does not...

Did you buy the remote from BMW coded to your car or from another source? You can get OEM remotes without Vin lock at ebay for $40-60 while BMW charger somewhere around $400

Great on the numbers, that's what I'm also always preaching. You never charge from empty 99% of the time. So it really doesn't matter how big the total battery is for home charger calculation. Only how far you drive. Most EVs get are getting around 4 miles per kwh. To satisfy that with 50...

BMW websites describe a different procedure: https://www.rallyebmw.com/how-to-program-the-bmw-key/ https://www.bimmer-tech.net/blog/item/24-replacing-your-bmw-remote-key-fob No idea if those apply for the i3. Call your dealer?

you are right, and it's all matter of perspective. I remember when Volvo built, super reliable (1.000.000km+) and practical cars in the 80s and 90s - and for this the company went bankrupt. People didn't buy new Volvos anymore, no need. In my opinion, we should have gone through the EV...

Just buy a Bluetooth OBD Dongle (40 euro) - spend the money on the BimmerCode (30-40 euro) software and do it yourself. It's fairly easy. Front Electronic Module (FEM_01) - select the Option "Fog lights deactivation" - change it to activated hit Code and that should it be. Let us know

I was just clicking through the technical manual and saw that the i3 BEV comes with 1.5L of transmission oil. (a gear oil) https://www.ecstuning.com/b-genuine-bmw-parts/hypoid-axle-oil-g1/83222295532/...

Thank you Havrla for making all this information available! It's great to keep this amazing cars going. The whole initial idea of the i3 to make this sustainable possible. Yet it got forgotten in the corporate world of higher sale figure and making more profit. BMW selling batteries - is...

Ok I understand what you meant now. Still part of this issue could be solved with programming the Rex to actually recharge the battery, not only hold the charge. It is surprising how little energy you need to drive straight. Here a little calculator...

The Rex implementation of BMW is mainly bad in the US due to compliance laws and has nothing to do with the technology. The euro version is much better. You can drive 90+ mph with the Rex on empty battery in Germany https://www.youtube.com/watch?v=CmCOdHZF91Q And the batteries sold today -...

lol I didn't do anything ;) thank rtanov this user provided the documentation.

while this is all good news - there is still little evidence that people need it :P I hope that we get to that tipping point that enough people have EV experience that range is not the main discussion topic anymore. Most people I know which got EVs that have enough range for their daily life -...

you got more of the body repair documents?

water in the break fluid may corrodes components of the break system from the inside. Had many master brake cylinders started leaking because of the lack of changing the fluid. I think the boiling point, is a non-issue at a city EV which brakes mainly with regen. Yet since everything at a...

I go by ear - when I push the trigger it takes like 2 seconds until I hear a relay click. So if I would to yank the plug right away I could be able to get the plug out before that click occurs. When I looked at the j1772 standard - there is a 1khz PWM signal on the pin which gets changed when...

When you work in Energy Economics - you just remember the 8766 as hours in year. Everything in that field is annualized. Don't care about bi-weekly or monthly stuff. Standby is always. I respect good quality products, I hate stuff which don't last. But I also know my use cases very...
