Daft question but does anyone know if the BMW i3 can recharge from Ecotricity rapid chargers with the Zoe connector at 43kW?

No, the i3 can only charge at 7kW using Type 2 AC. To go faster you need a CCS DC charger and an i3 with the CCS option.

if you dont spec CCS on an i3 at purchase can it be enabled later, ie is it a software upgrade or do they not put the connector in as standard

does seem a little short sighted of BMW to support CCS and push for it to be mandated then not put it on very car

The i3 can charge using the 43Kw A/C connector at ecotrictiy posts. But the car will only use 7Kw so it is not rapid charge. It is no different to using a 32Amp outlet at home.

The CCS option has to be taken at purchase, the non CCS versions only have a type 2 socket on the car. Perhaps it is possible to retrofit but i expect it would be far more expensive.
From my experience of having an i3 REX for a week's extended test drive, the electric mileage was around 70-80 miles and total range around 160 - 170.
All my videos can be seen on ELMS Cambridge facebook page, I might try and upload them in another thread...

Had an other thought, all the cut away pictures of the non Rex i3 show a gapping hole next to the ELEC motor, the space where the Rex engine and Gubbins goes. Why didn't BMW fill this space with batteries? The added weight would surely have been no more than the engine and the extra cost no more than the Rex? I don't know how much extra range this would of yielded though? Just a thought I had yesterday. Probably a very good reason for it.

I wouldn't have thought they can just add batteries in adhoc locations just because there is a bit of space!

Just seems a little wasteful to me. A bespoke add on pack for non rex cars can't be beyond the realms of possibility surely?

It depends on the architecture. We see from the Model S that the 85kwh car has more modules in series than the 60kwh car, which gives a different voltage. This is fine because the Model S was designed to work at these different voltages. The i3 is probably not. An alternative is to add a completely stand alone pack, with it's own BMS, and connect it in parallel. Unless it's the same configuration as the main pack it will either have less cells in series (so a lower voltage) and won't work, or it has less cells in parallel (so a lower capacity) and will therefore not neccesarily be able to handle the level of current heading out to power the motor or coming in from a DC charger.

I don't actually know much about the i3 battery cells, an auxiliary parallel pack may actually have been ok, but it would also have been massively expensive, I would guess something like £3,500 for an extra 6kwh. Make that a usable 5.4kwh, and with a generous 4m/kwh you get 21.6 miles, or £162 per mile.

Back to specs ;) and it appears the batteries are of much higher spec in the Soul EV than the i3 2013/14 model. Will there be a model revision to catch up this year?

"..The Soul EV gets an impressive 80-100 miles of real-world range when the 27kWh, 360v, 192-cell lithium-ion polymer battery is fully charged, and the regenerative braking system captures up to 12 percent of the Soul EV's kinetic energy when coasting and braking to also help recharge the battery..."

I feel a pantomine moment coming on "oh no it doesn't"!

Not sure if this has been mentioned elsewhere, so I'll pop it here.

My Chandlers BMW chap informed me today is that the heated seats (and associated HVAC bits) have become standard, and the price has risen by the £300 cost. Not unhappy about this. Wished I'd have specced it.

Now I have just typed that, I feel I have already said this somewhere in another thread. Hmm...

yep @Mark J Constable mentioned here https://speakev.com/threads/departure-time.5632/#post-74124 by me :):cool:

The dealer I spoke with said exactly the same as what you said. In hindsight I should of gone for the heat pump or though in hindsight I should of gone for the REX! o_O
