How BYD Blocked Onvo’s Production Ramp-up in China

Am I reading this right? So, $NIO-SW (09866.HK)$ gets held up due to $BYD COMPANY (01211.HK)$ battery supply issues, which it might have been able to anticipate earlier. For December, $Contemporary Amperex Technology (300750.SZ)$ will supply 6k to 8k per month. How is Onvo going to reach its 10k goal without once again purchasing from BYD to make up the difference in battery supply? If it does, how can it guarantee it won't face similar supply issues? Or have they already taken delivery of adequate battery supplies this time around?
