Electrical Distribution System and Method for a Vehicle with Two Networks Having Different Voltage Levels
First Claim
1. An electric distribution system for a vehicle with two networks at different voltage levels and an architecture in which at least a first of said networks is susceptible to being fed from the second voltage supply network through a CC/CC converter, one of said two networks being connected to a generator and at least one of said two networks being fed by energy storage means such as a battery, characterized in that it comprises several shunted CC/CC converters, connecting said first and second networks at different voltage levels, all of them connected at a common point or output, each one of whose CC/CC converters has a series or set of differentiated loads located in different areas of the vehicle assigned to it, belonging to at least the lower voltage network, the power that each one of said converters can supply being lower than that of the maximum consumption of all said loads it has assigned, such that the power supply to each load set will be carried out at certain moments at the expense of at least more than one of said different CC/CC converters or of a battery, and in that said converters, in order to supply different load groups located in different areas of the vehicle, are integrated in a master/slave architecture controlled from a control center or master, including a microcontroller with the capacity to manage the power to be sent at all times to the loads by each one of said converters in a synchronized manner, the connection between CC/CC converters, slaves, and control center including at least one communication bus such as a CAN or VAN bus, by means of which the needs of each load group are reported.

Abstract
An electric distribution system and method for a vehicle with two networks at different voltage levels. It consists of an architecture with a network r1, fed from another network r2, or vice versa, by a CC/CC converter, with network r2 connected to a generator G and feeding a starter motor S, and both networks r1, r2 connected to corresponding batteries B1, B2, comprising several equal CC/CC converters C1, C2, C3 in shunted arrangement between r1 and r2, connected to a common point and each one supplying a set of differentiated loads Q1-Q6, the power of each converter being lower than that of the maximum consumption of the assigned loads, whose converters C1, C2, C3 are integrated in a master/slave architecture controlled from a control center M with a microcontroller managing the power to be sent to the loads by each one of said converters in a synchronized manner.
