Abstract

A hybrid vehicle 10 which includes an assembly 13, a low voltage battery 14, and a high voltage battery 12. Particularly, the assembly 13 allows the on board low voltage battery 14 or another low voltage donor battery to recharge the high voltage battery 12 in an efficient manner while concomitantly reducing the likelihood that the high voltage battery 12 will be unnecessarily or inadvertently recharged while concomitantly ascertaining the existence of a fault within the high voltage battery 12 and preventing charge from being communicated to the high voltage battery 12 when such a fault has been detected.
