In a next block 320, computer 104 determines a range of voltages and current that the HV battery can provide via the HV variable DCDC converter 140. For example, an 800 V battery with a full charge may be able to supply voltage between 12-800 V over a range from 5-20 kW via the HV variable DCDC converter 140 based upon the HV battery architecture and the buck/boost capabilities of the HV variable DCDC converter 140.

In block 330, the computer 104 receives multiple requests for power to be supplied to one or more EPTOs, as disclosed in the process flow of FIG. 2.

In decision block 340, the computer 104 determines whether the requested voltages are at the same level such that the HV variable DCDC converter 140 can provide the requested voltage and current within the variance tolerance.

When the result of decision block 340 is “YES”, the computer 104 provides control signals to the HV variable DCDC converter 140 to supply power from the HV battery to a plurality of EPTOs concurrently at block 350.

When the result of decision block 340 is “NO”, the computer 104 provides control signals to the HV variable DCDC converter 140 to supply power from the HV battery to one or more EPTOs sequentially based upon the request priority and variance tolerance at block 350.
