CIRCUIT AND METHOD OF CONTROLLING VEHICLE BATTERY CHARGES
First Claim
1. Automobile management system using two batteries comprising a primary battery (B1) designed to power a primary service network (1) connected to one of its terminals (2), to which a generator (G) is also connected, a second battery (B2) designed to power a secondary network (3) essentially assigned to start-up functions and a BCO2 switch managed by a control unit or module (5) which, depending on the status of the charges of both batteries (B1) and (B2) and the charge demands of the mentioned networks (1) and (3), enables current flow between the two networks (1) and (3) in any direction, its characterized by the use of a unidirectional current flow device (4) that can bridge permanently the aforementioned BCO2 switch located between the two networks (1) and (3) and respectively powered by the mentioned batteries (B1) and (B2), whose device (4) provides current flow towards the start-up battery (B2) smaller than the current flow through the BCO2 switch, when it is closed, and also smaller than the current from generator (G) to battery (B1).

Abstract
Management system for a vehicle with two batteries and method that encompasses a battery (B1) that feeds network charges (1) connected to one of its terminals (2), a generator (G) in the mentioned network (1), a battery (B2) for a secondary network (3) and start-up functions, and a BCO2 controlled switch which depending on the status of the charge of (B1) and (B2) and the demands of charges C1, C2 from networks (1) and (3), enables current flow between networks (1) and (3) in any direction, including a power barrier diode (4) That bridges the mentioned BCO2 switch providing a current flow smaller than the one flowing through the BCO2, when it is closed, and also smaller than the current going from the generator (G) to battery (B1). This method provides energy transference between batteries (B1) and (B2).
