Much detail omitted:
Our conclusion for today is that the 2021 Tesla Model 3 Long Range AWD offers great charging performance. Unfortunately, the peak charging power is not maintained too long.
The data suggests that the versions produced in the previous years charged even faster, but this requires some more evidence.
The comparison with the Hyundai Ioniq 5 reveals that there is no match for the South Korean car either in terms of the average charging power and the range replenishing speed in 20-80% SOC window. If the Ioniq 5 charges quicker than Model 3, the range replenishing speed will be better also compared to one of its main competitors, the Model Y.
Finally, we must remember that the Tesla charging results were achieved at a V3 Tesla Supercharger (250 kW). Not all Tesla Superchargers are V3. In Europe, Tesla Model 3/Model Y can use also CCS2 fast chargers, but the charging output (despite power of up to 350 kW) might not be as high as on the V3 Superchargers. We will try to get into it in one of the next analysis.
