pls let me know if I can provide any information.
AC induction motors need, guess what, AC. Batteries supply only DC. You would need an inverter, and a battery. To do the calculation, I have this idea that the ratings on the motor may be important, don't you think? Also important is how long the battery has to last before it is discharged. But AC induction motors tend to be large, which means a large or very large battery at a minimum.
a very large one (look at the data sheet and maybe you can find some suggestion)
