Wait till you try a Shell rapid charger on the motorways… about 90p / kWh 😵‍💫
I'm amazed at the number of EV drivers that use the Shell Recharge points just 50 yards from my local O2A Tesla chargers which are ½ the cost. All I can think is the Tesla chargers aren't listed in the nav like non Tesla chargers are. Tesla doesn't come up on our Ioniq 5 charger listening, it's marked as "other" instead.

Like Ali, it's the exception for us to use public charging, with 300 miles of range, we seldom go more than 150 miles away from home.

I avoid Shell like the plague.
I often wonder at Reading West, sat on the open Tesla chargers watching everyone use the Gridserve opposite 🤔.
I think you’re right - it’s just not well known or highlighted on mapping.
 
So, can anyone use the Tesla chargers?
I was under the impression they are different to the usual.
This is all new to me, my missus has a new EV Mini.

Some, not all, are open to any vehicle but must be used via the app.
Download it, then take a look - when you don’t link the app to a Tesla, it’ll show the open ones only. You can also filter a map via their website.

There are several hundred Tesla charging stations that are open to all, in EV circles these are known as "O2A" Superchargers.
If you download the Tesla app, you have the option of only showing O2A locations.

While I'm not impressed with Musk and his moronic ideologies, his Supercharger network is pretty much the cheapest way to fast charge an EV, unless you have an 800V EV like us, which is slow to charge on a 400V unit, although it's still very cheap by comparison to faster charge operators.

You don't need to pay by app at all locations.
If it's a V4 charger, then it has a screen and contact-less payment window for direct card payments.

Sorry for taking you thread slightly off topic Ali.
LOL, no probs, anything EV related is OK for here.

On that note I needed to make a small adjustment to one of the cells in the pack.
I'm not sure why but the last few times I checked my BMS I noticed cell 89 had drifted a bit low so decided to manually pull it back up.

I'm using an old eBike 36V (nominal) battery through a DC to DC buck/boost to charge it. Most of the other cells are around 3.74V so I'll bring it up to that but it has taken a few hours to charge this far from around 3.695V.
55mV may not sound like much but it's important to keep the battery balanced and as some cells are a little bit higher the imbalance had crept up to 65mV.
The issue I have with my setup is the BMS can only be used when the car is stationary (long story) so when I charge the car I'm going by total voltage to decide when it is fully charged rather than the voltage of the highest cell. If a cell was to get too high or too low it would get dangerously close to the maximum or minimum voltage for a Li-Ion battery which would not be good.
I try to keep all cells at least 50mV below 4.2V when the car is fully charged so having one cell a bit low would not effect the charging too much but could cause issues at the lower end. If I need it I have spare battery modules so can replace this one fairly easily, thankfully it wasn't one of the ones in the fuel tank area.

Maybe you have a weak cell Ali? Or perhaps there's an issue with the BMS balance circuit on that cell? Does the BMS carry out active balancing or passive balancing?

I'm thinking it might be a weak cell, maybe from the second pack as it had more miles on it so I'll keep an eye on it and if it goes out of balance again will replace it.
The BMS is not turned on enough to do any balancing and TBH probably wouldn't make much difference if it was on all the time. It came from a Nissan Leaf that had a 24kWh pack and as far as I know the Leaf packs commonly go out of balance too so I suspect the BMS wouldn't make much difference to my pack which is almost double the size. I think the balance resistors only adjust by a few milliamps.
