1. A system for activating a plurality of power features of a first vehicle, comprising:
a processor;
a multi-function converter unit comprising:
a DC-DC converter including a first terminal, a second terminal, a third terminal, and a fourth terminal,
a first electrical path including a first voltage source connected to a first energy switch, wherein the first electrical path is connected to the first terminal and the second terminal,
a second electrical path including the first voltage source connected to a first pre-charge resistor connected to a first energy pre-charge switch, wherein the second electrical path is connected to the first terminal and the second terminal,
a third electrical path including a second voltage source connected to a second energy switch, wherein the third electrical path is connected to the third terminal and the fourth terminal,
a fourth electrical path including the second voltage source connected to a second energy pre-charge resistor connected to a second energy pre-charge switch, wherein the fourth electrical path is connected to the third terminal and the fourth terminal, and
a relay switch connected to the fourth terminal; and
memory or storage comprising an algorithm or computer instructions, which when executed by the processor, performs an operation comprising:
controlling a plurality of switches of a multi-function converter unit configuration to activate at least one of the plurality of power features of the first vehicle, wherein the multi-function converter unit configuration includes the multi-function converter unit, the operation further comprising activating a first power feature of the plurality of power features, wherein the first power feature involves simultaneously charging an element of the multi-function converter unit configuration via a first grid that is compatible with the first vehicle and a charging a second vehicle via a second grid that is incompatible with the second vehicle.
