Running at a higher voltage reduces resistive losses in the cables, so the conductor size can be smaller for the same power transfer. The voltage chosen is a tradeoff between the additional expense for the higher voltage and the additional expense (and weight) of thicker conductors for lower voltages. I think the voltage in the PHEV is around 300V direct current (DC).
