Stolen EVSE

Forgot to include in my first post - NESS are another brand you can look at. I've installed a number of these over the years and had good results with them. If you're concerned with image quality, spend the largest part of the purchase cost on good quality cameras with adequate resolution. IP camera...

I don't currently have a system and I have a personal preference for wired over wireless, so if I was in the market I would be considering this system:

Very nice! Quite a bit of customisation work there. Does the hair dryer turn on from the heater controls on the dash or does it use its normal switch? Must say the "tell-tale" is a little worrying to look at when the power if off. Looks like someone is targeting the car. http://forums.aeva.asn.au/sm...

Drive by emission testing

I was discussing my EV build with a mate the other day and he suggested I leave a rear muffler on but put a bubble blowing machine in it so that when the car was running bubbles would flow out the tail pipe....I wonder what the emissions testing people would think of this. http://forums.aeva.asn.au/...

Here's a nice cutaway picture of the i-Miev gearbox:

As you can see, the gears all run parallel to each other so I don't believe oiling or direction will be a problem.

Anti i3 ad from Lexus

Interesting that the major car companies are now having to defend their choice not to deliver a full electric vehicle.

By the way, when I write "current" in this thread, you can assume I mean "charge flow rate". I'll use "present" for the other thing.

But here's the kick in the pants, in order to know the accurate SoC we need to charge and discharge to a known SoC - bit of a paradox really. I'm not getting what's paradoxical about that.

What I'm taking away from this discussion is that unless you charge to 100% SoC and discharge to 0% SoC each and every time you will see some form of memory effect.

Cheers for that weber.

Regarding creating an accurate SOC meter, what about creating a multiple axis lookup table in the same way they do fuel injection fuel mapping tables?

I was trying to work out where the capacity issue was. Am I correct in saying that there is no capacity loss due to this, but rather a perceived loss due to the variance in voltage?

It could be the same gearbox as they used both the P51 and the W50 gearboxes behind the 18R-G engines. I'm not entirely sure of the physical differences between the P51 and the W50 but I believe the W50 was the stronger of the two. Given that the P51 was built by Porsche/ZF it would be feasible that...

Thanks for the calculations Johny. My napkin workings at home have it at a conservative 5.79 seconds to reach 100 km/h using second gear alone.
