Oh my. 16 V and  32 V. The bus voltage I am working on is around 100 volta max. I can't use INA219 anymore, can I?
What project are you working on use such a  high voltage?dc or ac? are you using ext shunt? but you have too due to high Vbus, maybe you can try voltage divider apply before v+ & v-, (if you using ext shunt) monitor the Vshunt and play around with the coding to match with your output.

I am monitoring a battery pack of an electric vehicle. It is actually 7 battery connected in series.

I tried working with LTC2946 but Analog Devices is not keen in helping me with the code that directly talks to the chip.

Have you seen this library?  https://github.com/phishman/LTC2946
Yes, it tks to the demo board. The demo board is pre-programmed to talk to the chip.
