The new generation of Tesla Model Y drive has a built-in BYD battery that allows for a very fast charging speed.
Despite Elon Musk’s fierce criticism of the Chinese manufacturer in the past, Tesla and BYD have just entered into an industrial partnership: The Chinese manufacturer is now supplying the LFP cells for the Tesla Model Y battery drive. The data sheet does not change, but in practice refilling becomes faster.
Except for a slightly lower raw capacity (58 kWh vs. 60 kWh), the BYD device has the same maximum charging power of 170 kW. However, it shows that we should not rely on this value alone. This is shown by a charging curve published in the German TTF forum, which clearly shows the changes.
10-80% in less than 20 minutes for the Tesla Model Y?
While the previous CATL battery had a temporary power spike, the BYD module is more enduring. On this charge curve (in red) we notice that the peak is sustained up to almost 50% before slowly falling away.
This curve, with a pleasant profile (reminiscent of the Tesla Model S Grande Autonomy that we have been able to measure exclusively), allows charging times to be reduced. It remains to know the exact recharge time between 10 and 80%. However, according to some witnesses, the SUV could accelerate from 20 to 80% in just over fifteen minutes. For the 10-80% it would then take less than 20 minutes. On paper, it’s as fast as a Hyundai Ioniq 6. In practice, the average charging capacity is logically much lower: We calculated a value of roughly 130 kW, which would put the SUV in the very good market average.
