Nissan Leaf

They are supposed to be wiggly - that is how they lock together when laterally loaded, and still flex open to provide lots of edges when radially loaded.

Those sipes are essential in winter tires, they look fine to me.

It will be interesting to see if the energy consumption changes with the snow tires.

I am curious to see how they work, as well. They are the updated version of the tires that Chang Ho Kim used to get 118MPG in an EcoModder economy run a while back. The Nokian Hakka R2 is claimed to be lower RR than the original R's and are better winter tires.

I ran the GPS yesterday, and the odometer is still reading too high mileage: 57.6 vs 57.1 miles. That is slightly less than a 0.9% too high reading. i will continue the calibration measurement today.

That means that the Leaf SL / SV tires that are 25.5" in diameter (vs these Hakka R2's with a 25.7") are also reading too many miles.

I installed our JuiceBox!! Woo hoo! It is charging at ~7.1kW - which would explain how it was charging more quickly than we expected it to.

Is that a mini display on the juice box about the white label?

[NeilBlanchard]

The display is small - it shows the charge information. I'll get a closeup of it.

Does it log? or just give current instantaneous info?

[NeilBlanchard]

It logs the data. If I can get the wireless module to link up with my network (it requires a WPS button on the router) then I can monitor all of the charges on my computer! :-)

Here's some readable shots just after I plugged it in tonight, taken with my dSLR instead of my phone:



That's the wireless antenna across the circuit board. I need to enter in my actual cost per kWh; which is 18.6¢ at the moment.

Tomorrow I can post the first full charge with a Level 2 EVSE. (EVSE stands for Electric Vehicle Supply Equipment, by the way - lame-o acronym if you ask me.)

Do you have it on a 30 amp breaker or is that just how it came (programmed to 29 amps max)? Or did the car limit it to 29*240 which= 6960 Watts less losses.
