Re: Is my battery dying ?

Time for an update on the dying cells situation. So I've made the decision that I may have to do a cell swap of cells 25, 69 and 70 myself and am currently in the process of sourcing some cells and trying to talk my other half into the idea that I actually need to buy them even though the car is st...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

DBMandrake: On all the 2010 IMIEVs here in Australia with the original charger cord (no EVSE), The connector "Guns" have the trigger that connects the proximity pin to ground when the trigger is released. All of the EVSE and charging stations I've come across here in Australia also have t...

Re: Pack Voltage versus SOC graph or table ?

Not wanting to rain on your idea, but the minimum cell voltage at low SoC seems to change as the cells age and lose Ah capacity. For example here is my car at 0% and 10% SoC back in April at 41k miles: https://drive.google.com/uc?export=download&id=1pb3urU35sXyY0ht8Yz9LLdQYdwLdzz5Q https://drive...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

am I understanding this correctly that these cap and resistor are there to protect the relay contact, mainly upon disconnect ? No. The relay merely shorts the pre-charge resistors, so that full power is available for charging. Certainly, it's best to stop charging by the switch on the J1772 connect...

Re: Is my battery dying ?

What degree of battery malfunction causes it to indicate less than 16 bars after fully charging ? A usable Ah capacity below a certain threshold ? To not show 16 bars after a full charge, pack charge level would need to be 92% or less, as this is when the top bar disappears when driving. Yes I unde...

Re: Is my battery dying ?

Not that it's worth bragging rights, but I think my battery's sicker than yours. Most recent low SOC capture was a month ago, when resting but not charging at 6% SOC, Cell#8 was 3.72V while Cell#18 was way down at 2.90V. That's a pretty big spread! Pack voltage was 304.8. Previous capture a month p...

Re: Is my battery dying ?

Does the car charge to "Full", i.e. 16 bars on the fuel gauge? Failure to reach full is one criteria for pack replacement under warranty. Yes it does charge to 16 bars, however I've noticed on Canion that sometimes it stops at 98% instead of 100% on a Level 2 charge. What degree of batter...

Re: Is my battery dying ?

Time for an update on the dying cells situation. Capacity has continued to drop at an alarming rate and it does indeed seem that cells 25 and 70 are slowly but surely dying, with cell 69 also showing signs of being halfway as bad as 25 and 70, with the other 85 cells still looking relatively normal....

Re: Canion

For me this problem was caused by one of the recent updates. I always exit the program cleanly with the back button so it wasn't that. To fix it I simply reconfigured the two screens - touch on the left hand side of each line and you choose what you want displayed there. My TripTimer and My TripTime...
