Re: help with reader error codes?

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?

Re: help with reader error codes?

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...

Re: help with reader error codes?

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 :shock:

Re: Tesla using LFP in China

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...

Re: Aussie electric vehicle sales triple in 2019

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...

Re: ABS and Autohold Question

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...

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

Re: Aftermarket iMiEV battery upgrade project

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...

Re: questions regarding rewinding and stator insulation

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...

Re: questions regarding rewinding and stator insulation

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...
