Re: What happens when you run out of charge?

If you truly ran the 12vdc battery dead, the secondary recharge path may not be able to rejuvenate it. To safely try to fix that battery in that case, you need to disconnect the HV charging with the disconnect switch, then you can do whatever you want to the 12vdc battery. It's only a danger if the ...

Re: Went from leasing to owning

If anything, being narrower than most tires, means that the tires have less chance of running over a nail.

Re: i3 EDrive External Sound

There are at least several websites that will allow you to decode the onboard options as built by inputting your VIN. Now, how easy or hard it might be to add additional things after the fact, often, it's not particularly easy. BMW, and many modern car manufacturers, no longer include the wiring for...

Re: Servicing i3 REx

Servicing the REx should have no impact on the battery warranty.

The OEM brake fluid is moderately expensive, but most of it is labor to actually flush all of the old stuff out.

Re: What winter tires??

If you want winter tires for the i3, there are only two sold in the USA, the OEM Bridgestones and the Nokian Hakkapolita R3. OF the two, I think the R3 is probably a better tire. Note, they are only available in 19" and the narrower style used on the base i3 (not the staggered set - the same as...

Re: Bimmercode App experience?

I don't know about the i3 for sure, but most BMW's are programmed to never actually use all of the fuel in the tank. A couple of reasons, one, is there is usually some crud in the bottom and even with the filter, it's not a great idea to try to suck it all up. Two, the pump is lubricated by the fuel...

Re: Using REX to charge batteries

Essentially, not that I'm aware of. The REx, once it turns on, doesn't try to raise the SOC, only to maintain it. So, while it will come on automatically if your SOC reaches 6% (or higher, if you've coded it and remembered to turn it on), whenever it came on is the maximum it will try to bring the b...

Re: Workhorse W-15 Truck will use the i3 REx engine to get 310 miles...how?

One of the issues with the REx and the 75% turn-on threshold is that it is programmed to run at least 10-minutes once on. If it got triggered, and then you stopped or were now gliding down a long incline, 10-minutes might come close to reaching a point on the SOC that could become problematic. The 7...

Re: New battery tech

I think the systems using the super high capacity chargers are planning liquid cooled supply cables.

One interesting article I read said that a well-designed inductive charging system can actually exceed the efficiency of a wired one, at up to 97% efficiency, but that only works on acv, not dcv.

Re: Any mods

I transport my folding recumbent trike in the back, and over time, it ended up nicking the paint on the rear bumper cover. I picked up an OEM bumper cover (well, my sister did in England and shipped it to me) that fits like a glove, covers the top edge and outer edge and protects things well. Other ...
