Model Year 21/22 Charge/Power bars on dashboard

[ROM4443]

I get the blue power bar is the overall charge left in the battery but I’m wondering what the green bar correlates to?
I notice for the re-gen under braking this rises but what is it actually used for and why does it disappear/where does it go?
For example the green bar was maxed out yesterday evening after a good run but the next morning it was empty again.
Any help would be great, thanks

Green bar is the Regen , it gives you back energy , when the battery is full or near full then you don't have green bar because it can't get back any more power, also at very cold climates even with battery at half of charge again the green bar is not full , also after a good downhill (for example if you leave at a mountain) after 10-11% of battery gain from regeneration then the green bar is no more available .

No, the blue power bar is NOT the charge left in the battery - that is the horizontal indicator visible in your photo under the car pictogram.
The blue "Power" arch (of the circle) is showing what it says: available "Power" from the HV battery: you might have 100% state of charge, but the blue arch/bar could be at half-maximum. That's simply because the system cannot take from the battery high-enough currents to deliver the maximum power (power = voltage x current). Those limitations may occur when the outside temp is too low (or sometimes too high).
For the green arch/bar you might have the same scenario: tha battery might be almost empty (so there's enough capacity to store energy from regen), but the battery temp is so low that it cannot charge with high currents. Consequently, the green arch length will be shorter.
