Question about Seal intentionally reducing power after speeding

I've noticed the BYD Seal (Performance) caps the performance to around 350hp (instead of 530hp) after I floor it on the highway. It stays capped at 350hp until I park and leave the car off for a while (say 30-60 minutes), then the performance goes back to normal and I can achieve the full 530hp again. Since this was not a particularly hot day and the battery had plenty of ventilation, I am wondering if the car automatically assumes that the battery might be hot after going fast (over 160km/h). Just like a printer assumes that the cartridge is empty based purely on the number of documents it has printed (instead of actually checking the ink level). My question is: does the car actually know that the battery is hot? Or does it work like a printer and makes assumptions based on a programmed usage scenario? Automotive Industry

This lowering of power is a safety feature that protects the battery from overheating and is not exclusive to the Seal. Other Chinese performance electric vehicles , like the SU7 and YU7, also reduce power after high-speed driving. The system likely anticipates rising battery temperatures, acting proactively. From a manufacturer's viewpoint, this conservative approach helps prevent battery overheating, extending battery lifespan. Autos & Vehicles

Thank you, so it's more similar to the printer then, it assumes the battery will be at risk and caps the output.
