Chinese Tesla Model 3 SR+ – real range 408 km at 90 km/h, 300 km at 120 km/h Good [video]

Bjorn Nyland tested the Tesla Model 3 Standard Range Plus range made in China, that is, with a heat pump and battery built on lithium iron phosphate cells. In terms of range, the car turned out to be slightly better than the version leaving California. It was also slightly heavier and held a charge better on the charger.

Tesla Model 3 SR+ (2021) – range test

The car is standard, with 18-inch wheels with Aero hubcaps, tinted rear windows and an aluminum cladding under the glass roof to reduce cabin heat - Bjorn Nyland's latest invention. the weather was beautiful, the sky was almost cloudless, the temperature outside was 21-23, at one point 26 degrees Celsius.

As mentioned, the Chinese ("MIC") Tesla Model 3 has a battery with a capacity of just over 50 kWh with LFP cells. The car turned out 120 kg (7 percent) heavier than Model 3 with NCA cells produced in California. He weighed in with the driver 1,84 tons... The same weight was for Volkswagen ID.3, 1st 58 kWh, 20 kg less for Nissan Leaf e + 58 (62) kWh, 20 kg heavier than Hyundai Kona by 64 kWh:

During the movement it turned out that at 120 km / h, the car is quieter than older Model 3 models. The final energy consumption is 16,6 kWh / 100 km (166 Wh / km) at 120 km / h and 12,2 kWh / 100 km (122 Wh / km) at 90 km / h! As a result, on one charge the actual range of Tesla Model 3 SR + "Made in China" is:

• 408 kilometers at 90 km / h,
• 286 kilometers at 90 km / h while driving in the 80-10-80- ... percent [our calculations],
• 300 km at 120 km / h,
• 210 km at 120 km / h for 80-10-80- ... percent [our calculations].

The values ​​are slightly better than in the variant with the NCA cells, but during the test some interesting facts came to light. First: although the driver can benefit from a very similar battery with a capacity of around 50 kWh, batteries with LFP cells had a larger buffer (reserve) than based on NCA cells.

Second: with the battery only 8 percent charged, the car was still rated at 186 kW (253 hp).. So it didn't seem slow. This is the result of the use of LFP cells, which have a very flat discharge characteristic, so that the voltage across the contacts is the same over almost the entire operating range (360+V for battery at 100%, 344V at 8%). . A stable voltage is a stable available power.

And finally, the third: after connecting to fast charging, the car started up from a place from a charge with a power of 140-141 kW, i.e. 2,8 C. After 14 minutes at 54 percent, the Chinese Model 3 SR+ was holding 91kW, still plenty (1,8 C) – so the load curve was flatter than the US Model 3 SR+. And this means a shorter stop at the station:

By the way, we add that those that were replenished with 14 percent of the batteries in 46 minutes, allow you to ride:

• 188 kilometers at 90 km / h,
• 138 kilometers at 120 km / h.

So when driving on the highway it will be +10 km / min - a quick stop for the toilet and a leg warm-up can add such a range that we will easily reach our destination.

Worth Watching:

Note from the editors of www.elektrowoz.pl: As Nyland rightly pointed out, a larger buffer can be useful in winter. LFP cells do not like frost very much, so additional, seemingly inaccessible to the user, the battery capacity could appear there on purpose, so that the car has enough energy to heat the battery.
