Using an Azure DMOC AC motor driver (inverter) with an Lithiumate BMS.
A contactor is not required when using a DMOC motor driver, as they include internal contactors. However, its precharge time is extremely long, and unacceptable for vehicle applications. Therefore, it is best if the battery is always connected to the DMOC, and the DMOC is controlled off and on through low voltage signals.
A load current sensor is required when using a DMOC motor driver.
DMOC motor drivers are sold pre-configured for either wire control or CAN control.
If configured for wire control, they can be used as any other analog motor driver:

If configured for CAN bus control, they require a VCU (Vehicle Control Unit) to translate between the various signals on the CAN bus (BMS, throttle, etc.) and what the DMOC expects.
In particular, there are at least three reasons why a VCU is required:
