Why might an electric car plugged into a 150 or 300 kW charging station sometimes only receive 60, 40… or even 30 kW?

In this video, we'll explain how a charging curve works, why the power decreases as the battery fills, and what factors determine the actual power output: battery pack temperature, charge level, BMS, vehicle architecture, recent battery history… and also any limitations of the charging station.
