NEV owners in China have claimed some EVs originally capable of around 500 km CLTC range were reduced to less than 300 km in real-world usage following remote OTA updates that modified battery management parameters.

 

Chinese state broadcaster China Media Group has published a detailed report on so-called “battery locking” in new-energy vehicles, with some owners also reporting that DC fast-charging times increased from around 40 minutes to 70 minutes after software updates.
