I stopped by this V3 supercharger on July 3 with my M3 at 42% SOC to charge. Stall 2D on the far end would only give me a constant 27 kW even after I gave it plenty of time to ramp up. When I switched to stall 1C it ramped up to 103 kW instead of what would normally be expected from a V3 supercharger charging up from 42% SOC (which would be around 155 kW). It basically acted like a V2 supercharger from that point on until it finished charging me up to 82%. I was the only car there. It looks to me like it needs some major adjustments and thorough testing.
Battery probably wasn’t warm enough upon arrival. 27 kW on 2D is definitely abnormal but 103 kW seems pretty reasonable for 42% if you hadn’t been driving for a while prior to charging.
