Is the zero app "obdzero"? Looks like it has all the info you need to monitor the pack, even though it looks a bit utilitarian.
How out of balance were the cells after your drive? And after a recharge?

You might want to drive a bit further to make sure it doesn't fall off a cliff at 40% or something silly. What sort of obd adapter are you using be because they can be hit and miss on what cars, phones and apps they work with, especially the cheapest ones. Not saying the expensive ones WILL work but...

saying cells were now sitting between 3.42 to 3.74 That's a pretty wide range, sounds like there might be a bad cell (or a couple of cells) causing the majority of the lost range. 30Ah make the battery out to be 60% state of health, so quite degraded but if your happy with the new range then keep d...

Give me 20kWh usable capacity EV with 100-ish kW fast charging capability and infrastructure

That is the only real hold up I can see for small cars, smashing 100kW+ into a 20kWh battery. Its easy enough on a 100kWh pack, that's only 1C but into a 20kWh pack all of a sudden it's 5C

Agreed, especially if there was a DC fast charger network worth speaking of around here. I get by with 80km of range but a bit of a buffer would be nice. 150-200km I think is the sweet spot to not have "range anxiety". On the rare occasion I'm travelling (in an urban commuter car) I'd be happy to st...

Looks like Tesla are going to take a range hit on the model 3 in China in order to lower costs even more https://www.mining.com/teslas-china-surprise-big-blow-for-cobalt-nickel-price-bulls/ Also clickbaity headline saying Tesla has shocked the world by not using cobalt, like Tesla hasn't been saying...

the energy density of the supercapacitor to a record 88.1 Wh/L (Watt-hour per litre), which is the highest ever reported energy density for carbon-based supercapacitors. Similar fast-charging commercial technology has a relatively poor energy density of 5-8 Wh/L and traditional slow-charging but lo...

The kona is 64kwh. Even at double the magic $100kwh that's still only $12800 in battery cost. The EV kona is $65k and the ICE kona can be had for $25k but if you want to compare apples to apples the highlander kona with an ICE is $40k. Add $15k for battery and it's still going to be $10k less than h...

Auto hold should not interfere with ABS on any car. Chances are that you just didn't hit the threshold for ABS to operate. Essentially the ABS module monitors each wheels speed and if detects that a wheel is slowing faster than the car could possibly be slowing down (ie it's skidding /slipping) then...

I can't help with manual but the "Google translate" app works pretty well for translating images from your camera on the fly.
Just hold the book in front of your phones camera and read the English text on the screen

they forgot to include some key features

Like insulation, Don't worry that's an unnecessary expense.

especially if not consistent with either plus or minus.

He corrected it to be only positive

Turned out it's just continuous between the case and battery (+).

Which is a lot less unnerving.

It's live alright - 0.01 ohms. So if you put a globe (or other load) from the negative terminal to the case it'll light up globe. Because that's not ideal. If its "just" the case acting as a capacitor then a short between cell cases isn't going to let all of the smoke out only drain the cell over t...

Here's what I've got 415V x 10A = 4150W 50Hz 415V / 10A = 41.5 Ohms (total impedance and resistance) Impedance @ 50Hz = 31.42 Err, that's like an equivalent impedance for the mechanical load (plus a small winding resistance and reactance). Impedance @ 100Hz = 62.83 If the impedance doubled at doubl...

Edit 4 Ignore the numbers , Im not thinking straight apparently, thanks coulomb for helping me see clearly what was staring me in the face. Here's what I've got 415V x 10A = 4150W 50Hz 415V / 10A = 41.5 Ohms (total impedance and resistance) Impedance @ 50Hz = 31.42 Impedance @ 100Hz = 62.83 (Edit 3,...

But yes, Current gives torque. However at a higher RPM there would be a higher current draw to make that extra power. If the voltage stays the same and the frequency increases, the current should increase too That depends on torque Higher frequency can mean less amps Volts x amps = power = Torque x...

I was under the impression is was frequency that gave you RPM?

That's right, my mind was stuck in DC world.
I did say I was rusty...

Not that it changes the outcome but is it actually live or just capacitance?

The current draw is not what gives you rpm it's voltage. Current gives you torque. I'm a bit rusty on motors but... If you rewind the motor from 1400rpm@415V like that it will end up as a 1400rpm@100V. Meaning if you want to spin the motor at 8400rpm you will need more volts. What you want to calcul...

It's sitting at about 344 V. Which is 3.91 V per cell. At the time I pulled the pack out the GOM was saying 31 km remains and was sitting on about 1/3rd charged. Interesting. I've been recording the voltages vs percentage in my outlander to try to create a bit of a graph for my NCM cells in my moke...

Geez, no pressure. Only 100 iMiEV owners hanging on this thread right now!!

I'll have you know there's an outlander phev in my carport that might want a battery upgrade at some point and I'm following your progress closely. So you can add the outlander owners on top of that 100

Well, $1000 to convert to English or an extra $20000 to get an English one from Nissan Australia

Bums in seats. Getting people in an EV and explaining the pros and how a lot of the cons are irrelevant. So more events like electrikarna and presence at community fairs and shows etc

Fyi

It's just off brand dynamat, like black and gold cornflakes vs kellogs. There's a difference but lots of people are happy with the cheaper stuff
