In use, the computer 104 can communicate with pieces of equipment that are attached to an EPTO and can receive the initial requests. During communication, the computer 104 can ping the equipment and, in response, the equipment (e.g., 171, 172) can use Ethernet or wireless communication to command, verify, and/or modify supply voltage within available range (e.g., 12-800V) and current against the total power capacity of the HV battery. CAN/Ethernet communication through upfitter IOA 114 can also be used between the equipment 171, 172 and the computer 104. Pinging frequency by the computer 104 can be low when power is not being used, and can increase in frequency during usage and in order to meet the variable DC depends of certain equipment.

The computer can also use voltage and/or current validation if the equipment 171, 172 has a current and/or voltage sensor. For example, the computer 104 can determine which piece of equipment is connected to each EPTO 161, 162, 163 connection by matching the equipment's voltage and/or current with that which is provided.

Based on the request of the equipment, the computer 104 will attempt to meet the voltage/current requests of each device independently and in sequence as prioritized. Also, included in the request, there will be a variance tolerance or tolerances regarding how much the voltage and/or current can vary from the request and still be acceptable in case the system is unable to meet the request.
