I have implemented field oriented control for pmsm motor .
FOC algorithm takes care of phase current limiting.
Can anyone guide me how can we do battery current limiting in foc ?

Ordinarily the battery current would not be limited except to disconnect or shut down to protect the battery. You could monitor the battery current and send a command to the FOC to reduce the limit setting if the battery current reaches a certain level. That would be somewhat problematic however because the battery current directly represents power and the motor current represents torque. At low motor speed, you can have maximum motor current with low battery current.
