Quick question to the experts in this forum: I own a SR/S Premium with chargetank (12KW charge speed). I live in Germany where we have a 3-phase electric system (220V) and bought the 10% Upgrade (Cypher Store).

If I run a test on a single phase I can see 11% higher charge speed. Currently I can't test on all 3 phases since the Battery temp is too low and SOC too high to max out the charging speed. But I have read before and after the update data from the MBB console during charging.

Apparently charger 1 is now on Ver 206, but Charger 2 still on Ver 204. Does someone know if 206 is a requirement for the 10% charge speed increase? In this case I would not get the 10% increase on charger 2?

I believe it should be ok. The previous generation of firmware was in the 1xx region.

Thanks for your feedback! I can now confirm, that 204 and 206 both works with the charger upgrade. I get now 13.018 kWh charge speed on AC and 12.429 kWh on DC if charging on a public 22KW charger. This is indeed 0.6 kWh more than what I got before the upgrade.

Guys, about the chargers firmware, is it possible to update them without going to the dealer? can I make my self? or any procedure to update?

I already have v8 (new dashboard) SRS 2020 Premium

Thanks
