Poor charging curve for the Tesla Model Y L (Long), the 6-seater extended version of the Model Y. 20-80 percent in 31 minutes

The first loading curves for the Tesla Model Y L have appeared online. This extended Model Y, not yet available in Europe, features six seats inside and a battery with a capacity of 88 (~84) kWh. It takes as long as 31 minutes to charge the vehicle from 20% to 80% capacity, and it can only maintain peak power levels for about 25% of that time. The car’s only advantages are its record-low drag coefficient Cx among Teslas, low fuel consumption on highways, and good range.

Tesla Model Y L. Spacious, slow to charge, but good for range and fuel efficiency.

The first graph comes from India, where a Tesla Model Y L was connected to a uniquely powerful 400 kW Alpitronic charger in the country. There, the Model Y L achieved a maximum power output of 249 kW at a voltage slightly over 400 V and a current just above 600 amps. The peak power range lasted for about 27 percent before dropping almost by half to 300 amps or less. This curve may not reflect the car’s actual capabilities, as the sudden drop in power suggests the charger had a connector that could only sustain 600 amps for a brief period of time (source):

A Hindu completed the 1,561-kilometer journey from Delhi to Kolkata with three stops for charging in 21 hours and 22 minutes. Considering the travel time, he drove throughout the entire day, including at night. For a regular car, Google Maps estimates the driving time to be between 20–21 and 30–32 hours (HERE).

The American version, connected to a Supercharger capable of delivering up to 325 kW, reached near its maximum power output at just 6 percent battery charge, and began to decline gradually from 15 percent (see illustration below; source). It took 26 minutes to charge from 10 to 76 percent, so we can estimate that the final 4 percent would take 2–3 minutes—unfortunately, the video ends too early. Interestingly, in the final stage, both curves are quite similar, although the American variant likely uses Panasonic Li-NCA cells, while the Chinese version has Chinese LG En Sol Li-NCM cells in its battery.

Prolonged charging stops don’t sound appealing, but the Tesla Model Y L is saved by its drag coefficient of Cx 0.216, which is lower than that of the Model 3 (0.219) and Model Y (0.22). And here things get interesting: the Tesla Model Y L Premium, with a battery capacity of 88 (~84) kWh and all-wheel drive, promises up to 682 WLTP miles on 19-inch Machina 2.0 wheels. The Tesla Model Y Premium with all-wheel drive has up to 622 WLTP miles. So, the larger, heavier model with more seating capacity has a range that’s 9.6 percent greater, even though its battery is only about 6 percent smaller in capacity.

Editor’s note from Elektrowozu: according to European homologation, the Tesla Model Y Long has a WLTP range of 681 miles. We took the 682-mile figure from the configuration tool for India.
