Hi what % should you charge your iX3 to each time you charge it and when should you charge your iX3.

Sorry to sound facetious. But charge it whenever your electricity is cheapest, and charge it to whatever % works for you.

For example, if I charge to 80%, in a normal week I would need to charge twice. Whereas if I charge to 100%, it means only having to charge once a week. Normally on a Friday night, in case I need it full for the weekend.

If your aim is to protect the battery in the longer term then the consensus seems to be that you should keep the battery SOC in the 20 to 80% range with the occasional charge up to 100% for cell balancing.

It is worth noting that all batteries have built in headroom: actual battery size versus usable. The battery warranty is based on a 30% reduction in the usable capacity which is greater than 30% of full capacity.

To put this into context, Tesla offers a 13.5kWh home battery. Under its energy plan, Tesla can discharge and charge the battery once a day for 10 years under warranty with a residual battery capacity of 80%.

In sum, if you are a 3 year ditch and switch EV owner, then charge in anyway that you want. More of a concern is the 12VDC battery.

On AC I charge to 100%,on DC toll it throttles hard (technically 94% but usually dips off at mid to high 80's)

I try still to 80 on DC as a rule unless need the range, but on AC fill it up, as long as its not sat at a high SOC then it's fine.

As BMW recommends that when the car is left idle for a long period (ie; some weeks) it should be left fully charged and plugged into an EVSE, then clearly BMW isn’t that worried about high SOCs and damaged cells.

Fair enough, general consensus in the ev community is to not leave a car at very high SOC for extended periods, perhaps BMW have a cycle system to discharge and recharge if its left on an EVSE though.
