Add 5% when REX maintain SOC is activated

Thu Jan 16, 2020 10:02 am

Problem:
Using REX to maintain SOC kind of works, but after some time you end up with battery running out in longer mixed drive trips when there is no time or a chance to charge. This happens because when you stop the car after highway speed to make a quick pitstop, the REX is usually falling a bit behind the value to be maintained. When you restart the car, your maintained SOC value is then lower than in the beginning of the trip.

Fix:
When maintain SOC is activated, the marker of the maintained battery level should be for example +5% the current state of charge. This way you would not lose charge because of a quick pit stops.

This should be rather easy to implement and even a one liner code change. ;)

What do you think? Any comments. I say: Please BMW implement this.

If you like to see this implemented give it your vote in the comments. ;)

Thanks! I have SOC hold enabled. I believe you did not read my message entirely. My question is not how to enable SOC hold, but a suggestion to set the hold level 5% above the current level.

Thanks anyway! :)
