Re: P1A15 fault on a Peugeot Ion

hi there, i have seen on the forums a failure of the pre-charge resistor itself, located inside the battery pack.... found it here - https://forums.aeva.asn.au/viewtopic.php?t=5788 It also details the location of the charge capacitor - so for some reason the capacitor on your car does not reach a hi...

Re: When to be concerned about Ah number

There is a guy named gary on the FB page for our cars; is that you? Yes I will look at canIon individual voltages when I get down to 3 bars and see what it says. Lately I have noticed that number 64 is running hotter than the others during charge. It is up around 29C while others tend toward 26 or ...

Re: Repair Service (Exchange) for Charger DCDC Converter

Hi.

I'll put some pictures on but i doubt its repairable, a hole has burned right through. Im comfortable with repairing electronics and I know some good repair guys who can do the stuff I can't.

Cheers.

Gary.

Re: Repair Service (Exchange) for Charger DCDC Converter

Hi there, I am in the UK and would love to buy some circuit boards from US chargers !!! The main board which seems to fail is the one with the big 3 capacitors on it, and I have a failed charger in my garage that has a hole burned right through the circuit board ! So far no warranty replacements ove...

Re: When to be concerned about Ah number

What does the warranty state about expected degradation? 35.6Ah is about right for the age of vehicle, that is about 77% battery health (based on 46Ah for a new vehicle). I doubt the warranty protects you against natural degradation, i've heard about pack replacements under warranty but that is wher...

Re: Turtle at Half Charge Under Load?!?!?!

Style wrote:Having same issue. OP-What was the resolution to the issue ?


This is generally caused by a battery cell going bad. Turtle is triggered by low voltage on a battery so even though the car has plenty of charge, one cell's voltage drops when it is used.

What country are you located?

Thanks.

Re: The aftermarket cell replacement saga

These look familiar !!!!!

Unfortunately the reviews say they are 40Ah version (LEV40).... damn it !

These are a good size and rating, unfortunately fairly expensive.

Re: The aftermarket cell replacement saga

It is difficult to know whether these new cells are good or not, whether they are well made. I am always suspicious of the capacity rating, i've seen too many 18650 cells with "9800mah" which is impossible. These cells are within the size of the originals, https://www.aliexpress.com/item/4...

Re: I would like to set the charge current lower than 5A

Hi there ! The charger will just not run at such low amps and it is very inefficient. There is a 600w overhead during charging, this is from running the electronics, voltage conversion, water cooling pump, monitoring and balancing inside the battery, etc. That means at 240v approx 2.5A is used by th...

Re: The aftermarket cell replacement saga

Hi there, fascinating work. I would say that the spray foam will not help with cooling so would be better to pack it with some blocks to hold it in place but allow air around it. Of course time/necessity often doesnt allow perfect repairs and it did the job. I've done the LTC voltage monitoring chip...
