DC-DC converter and energy management system
First Claim
1. A DC-DC converter for use with an energy management system of a motor vehicle, comprising:
- first and second voltage supply terminals having first and second nominal voltages respectively, at least one of the first and second voltage supply terminals being arranged for coupling to a battery; and
a third voltage supply terminal for exchanging energy with an external energy means;
wherein the DC-DC converter is arranged to exchange energy between the first or second voltage supply terminals and the third voltage supply terminal independent of the voltage and polarity of the external energy means.

Abstract
An energy management system for a motor vehicle has a first voltage supply terminal having a first nominal voltage and a second voltage supply terminal having a second nominal voltage. At least one of the first and second voltage supply terminals has a battery. A universal bi-directional DC-DC converter is coupled to exchange energy between the first and second voltage supply terminals. A third voltage supply terminal is provided for exchanging energy between the DC-DC converter and an external vehicle electrical system or battery charger. The energy exchanged between the first or second voltage supply terminals and the third voltage supply terminal is independent of the voltage and polarity of the external vehicle electrical system or battery charger.
