    My Black Beauty, i3 94Ahr Rex

    Approaching 8 years old, and this is my HV battery health status after the most recent full charge. If you look at the figures, the SOC and SOH figures are very close to each other. Does that suggest that the battery is in near full health? Or does dividing battery capacity by rated capacity...

    New EV Battery Health App

    @James:- I think you're rather missing a distinction here. The i3 rex may have a built in generator, but it is no way part of the 'drive train' it exists solely to generate power to the battery. The cars drivetrain is pure electric, this is not the same as a PHEV.

    Any experience with updating the GPS maps?

    BMW is for me one of the cheapest manufacturer map updates I've found, in that my i3 updates via a USB stick and is just £50 for a whole year of updates, which can be up to four in one year. My service agreement also included two updates in four years. You just need a large empty 32Gb stick, and...

    Rex & UK Road Tax

    The distinction is that your car was registered after March 2017, because that's when the vehicle tax rules changed away from emissions and towards vehicle value. My i3rex '66 plate pays zero tax. Is it the case that yours was 2018, and valued at more than £40,000 as an on-the-road price Inc any...

    myBMW App Works, But Not Showing Charge / Charging Status...

    Mine has not logged charge received last couple of times, but does slowly update to say fully charged at xx:xx hrs. Also don't seem to get 'notifications' as often as I used to, re charging etc, and what time car predicts itself as full.

    Black spots on Nav screen :(

    My screen before it was replaced by dealer under warranty, which I subsequently replaced (once out of warranty) with a 10.25" unit.

    Black spots on Nav screen :(

    Apparently fairly common on older model screens. My '66 plate i3 (2017 model) with a 6.6" screen developed this problem by itself. It grew from a tiny splodge a quarter inch across, to bigger than a 50p piece. My second hand car warranty eventually replaced it for free with a BMW item, claiming...

    DIY HV Battery upgrade

    That would be my thought also, once my battery warranty is expired.

    My intro message. BMW i3S is brilliant, but needs big range Solid State battery

    I contacted Lion Smart once years ago when that test i3 made headlines. They were quite clear that their tech would not be made commercially available to i3 car owners, and that their test i3 car was a 'proof of concept' demonstrator. They were (at that time) aiming solely at public vehicles...

    Regenerative braking question

    In the UK it's not unusual for me to gain back 2-3% on downward hills, all while keeping slight pressure on the pedal to maintain a safe speed. Balance that with the thought if you reverse your journey you're still using power.

    Highest Mileage i3/REX?

    82,000 miles on my '66 plate 94Ahr Rex, and no appreciable sign of battery range degradation in the three years I've owned it. I still get 100-135miles winter to summer. Only charged up to 90% at home unless I need the maximum range, and rarely fast charged. Battery kappa max still shows...

    Intelligent Octopus and 2018 94h i3

    Also, GPS location within the vehicle must be on, for the tariff/app scheduling to work at all. I too see random schedule times reported back to my bmw app, and also the occaisional 'could not control your vehicle'. These I just ignore, as the schedule sets uniquely each time, and car charges...

    Upgrade battery.

    JamesinLondon. You're so right, I'll be keeping mine for the forseeable..😎

    Upgrade battery.

    Based on my average miles/kwhr, I'd get something over 200 miles before the Rex cut in, assuming about 45kwhr usable. Which is similar safety buffers on my 33kwhr battery (27.5 usable). This really would make me rethink replacing my i3 for a higher range car in the future. I'd much rather...

    Upgrade battery.

    A 53 kwhr battery would be super news, please do keep us posted also on your plans for the other foreign 'branches' of your company. When recoding a car to accept an increased capacity, do you keep the BMW depletion & charge limits to protect the battery, e.g. users will see around 45 out of...

    My Black Beauty, i3 94Ahr Rex

    Upgraded 10.25" screen. Coded with my VeePeak ODB2 Bluetooth adapter, and a licensed copy of the Bimmercode app.

    Intelligent Octopus and 2018 94h i3

    Another thing to consider, after a recent experience of mine, is as and when you change app passwords. I did this as part of a new phone and changed all my passwords. The MyBMW app worked fine, so too did the IO app, well to all appearances anyway. However, IO suddenly stopped detecting my car...

    Is GeniePoint 11Kw charging being overstated?

    I use a bluetooth ODB2 dongle to monitor AC charging power, along with the 'Electrify App'. This shows the amount of battery actually charged, charging rate, along with lots of cell voltage, SOC, SOH info etc. In that instance above, % at start of charge was less than 25%. Then the 15Kwhrs...

    My Black Beauty, i3 94Ahr Rex

    I've owned a '66 plate 2017, 94Ahr Rex for three years now. In this time I've seen the seasonal variance in range, from 100 to 135 miles electric, and 70 to 100miles on the Rex. My personal record for distance, without the Rex cutting in, is 132 miles with 9% battery still left. I drive evenly...
