Re: Car to car charging

V2V perhaps , could be added to the Level III - DCFC Protocol . It might be complicated by the fact that voltages differ by vehicle . Maybe a V2V device would simply connect both DC lines and communication lines of the 2 vehicles . They could communicate their information and then base their action ...

Re: 12V Battery maintainer circuit

What I'm thinking of is a maintenance cycle . Low current battery maintainers or tenders have a mode that helps in the longevity of the battery . Desulfation is one word that I've seen , I'm not sure that it is applicable to our 12V battery though . But improving the battery's longevity would mean a...

12V Battery maintainer circuit

I think it would be possible to have a 12V Battery maintainer programmed to turn on for a short period (1/2 hour ?) whenever the vehicle is turned off . The DC-DC converter would need to be on during this .

Re: Music collection shuffle option?

I have a USB memory stick in both my 2016 and my 2020 . I've found that the 'Random' does mix up the order of play but some songs will play a second time while others have not played yet . Perhaps that's why it's called 'Random' and not shuffle . I would prefer a proper 'Shuffle' option where the or...

Re: 2015 i3 REX with 114k for $10,000

There has been a suggestion that you can use an OBD II scan tool to find out how many hours the REX has run . Maybe search REX hours .

Re: ICE Pickup or i3 pulling small trailer?

It could prove a challenge to wire up a brake and tail light harness . In our i3 s the lights are LEDs mounted on a printed circuit board . I think it could be done .

Re: Bought an i3, thoughts after a few months

Some research shows a single ratio fixed 9.665:1 transmission results in indeed a very high speed for the motor/gen at maximum speed . With our different tire sizes having Rotations per mile from 729 to 740 , calculating for 95 mph should go something like this . 95 / 60 = 1.5833 , 1.5833 X 740 = 1,...

Re: Standard socket charger

As for the EVSE , it might be shown on the details label as a maximum current Amps . But yes , your control over what the car is set at is how to manage the issue .

Re: How is your battery holding up?

Here's a suggestion . Set a 'Departure Time' while charging on Level 2 . Does that process warm the battery to 25 o C ? If so then that could be the best Max Kappa that you can get . We can try this test if we're wondering what our capacity is .
