Re: Aftermarket iMiEV battery upgrade project

Well done Andreas! Yes it's always a bigger job than first imagined. Glad you got everything to fit in the end. The two 4-cell modules weren't too difficult to manage? I had to replace both side (resp top and bottom) walls with thinner ones. The thickness of these modules is critical, the cover sit...

Re: Aftermarket iMiEV battery upgrade project

Ok, after a long delay I can now report that the 60 Ah cells that originally were in Perth are finally installed in my iMiEV in Melbourne. Well done. Is maybe the connection from the cells to the board poor? Could I despite the double and triple checking of the connections have missed this one? Yes...

Re: Aftermarket iMiEV battery upgrade project

Ok, after a long delay I can now report that the 60 Ah cells that originally were in Perth are finally installed in my iMiEV in Melbourne. There is some good news and some bad. As far as the physical work of fitting the CMUs into the frames and base I am quite proud of what I have done. Once I had t...

Re: New Zoe! Way to get the 15A ZE Ready Portable EVSE?

Ditto on that. Just a Zoe thing. The Chameleon charger that only Renault use, and only in the Zoe, is a funny beast that uses the motor controller and motor as the charger rather than a separate AC to DC rectifier. Result is high power AC charging (up to 43kW in some models) - but is quite (read ve...

Re: Aftermarket iMiEV battery upgrade project

Whot you mean about battery Molicel INR-21700-P42A? Maximum charge is 8.4A. With use 15pcs. We have max charge 126A.

Re: Aftermarket iMiEV battery upgrade project

As for DC fast charging, my guess is that a suitable current (likely 125 A) is requested, and if it only appears that ≈55% of that current is supplied, it just shrugs and assumes it's a lower power fast charger. When a cell voltage approaches too high a voltage (these are pretty similar for LMO and...

Re: Aftermarket iMiEV battery upgrade project

In hindsight, I should have urged Joe to set up Canion or similar last week, for extra peace of mind. To watch amps , low and high cell voltage or whatever one might be interested in , I use EvBatMon. Just select the Gauge of interest and place it where it suits, the numbers are nice and big and vi...

There is another guy in brisbane, Daniel Rykiert, that has put a second 150AH pack in the back of his Minicab. Not sure if he is an AEVA member. I just lurk TBH. Anyway he has it spliced into the wires to DC wires to the motor controller. I added the main positive and negative of the add-on pack to...

Re: Aftermarket iMiEV battery upgrade project

Thanks Mike, I am not at all worried about freezing, yes I know it can be unpleasantly cold in Melbourne but the iMiEVs range is to short to head into the snow!

Re: Aftermarket iMiEV battery upgrade project

Encapsulation epoxy to create a path from the sensor to the cell top? The distances between the voltage sensors and the cells vary due to the cell layout. I don't see that as a problem (hope I'm right). But I fear that it is not possible to direct the cell temp to the correct sensor over a distance...

Re: Aftermarket iMiEV battery upgrade project

I am looking for ideas of how to ad one or two additional temperature sensors per module on the 60Ah aftermarket project. The temp sensors on the BMS boards will be too far from the cell tops for my piece on mind. It will be easy to place a probe near the centre of the module but how to monitor 22 o...

Re: Aftermarket iMiEV battery upgrade project

Do you have a handle on how far it'll actually drive until power gets reduced? (i.e., not just lighting the turtle, but actually acting like one.) After the 12%/10% turtle light, I believe that when the estimated SOC gets to 0%, the car stops dead. Like a turtle 🐢 on its back :o I test drove my iMi...

I feel its using the lower part but I really need to examine it closer.. I agree the lifespan should be great even as it is now .. but much better too if we can get to the other 45Ah.

Re: Aftermarket iMiEV battery upgrade project

I can agree with that.
