A controlled power transfer system and method in networks with sectors fed by different batteries. An architecture with two batteries B1, B2 for networks (17, 18) provided with a unit CB1, CB2 with a control module (10, 11) of the SOC/SOH of B1, B2, power distribution boxes SDN1, SDN2, SDN3 with a microcontroller (1, 2, 3) and communications bus (19), is provided with a detecting device (30) of the voltage and/or polarity of an external supply susceptible to being connected to said batteries B1, B2, and controlled switching devices (33, 34) for routing the external power flow to one of batteries B1 or B2, said boxes SDN1, SDN2, SDN3 being interconnected and connected to said units CB1, CB2 for permanent monitoring of the SOC/SOH of said batteries B1 and B2 and to provide a controlled power transfer between them.
A controlled power transfer system in networks with sectors fed by two different batteries, applicable to automotive vehicles, with an architecture comprising at least a first battery B1 and a second battery B2 which can be charged from a generator G, both batteries B1, B2 being provided with a unit CB1, CB2 integrating at least one control module (10, 11) of the state of charge and state of health SOC, SOH of said batteries B1, B2 which feed respective networks (17, 18), a first one of them (17) integrating security and supervision or stand-by modules, and the second one (18) including at least one start up device, power being distributed to said networks (17, 18) from power distribution boxes SDN1, SDN2, SDN3 which include a management microcontroller (1, 2, 3), and the system integrating a communications bus (19), characterized by also comprising a detection device (30) of a voltage and/or polarity level of an external supply susceptible to being connected on at least one of the posts of one of said batteries B1 and B2, and controlled switching devices (33, 34) for routing said external power flow to a predetermined one of said two batteries B1 or B2, and in that said power distribution boxes SDN1, SDN2, SDN3 to the loads are interconnected and connected to said control units CB1, CB2 of batteries B1, B2, for carrying out permanent monitoring of the state of health and state of charge of said two batteries B1, B2 and providing controlled power transfer between the two batteries B1, B2, at any time, even in a situation when the vehicle engine start up key is off, regardless of consumption required by the loads and in prevention of future demands.
A power transfer control method in networks with sectors fed by two different batteries, applicable to automotive vehicles, with an architecture comprising at least a first battery B1 and a second battery B2 which can be charged from a generator G, both batteries B1, B2 being provided with a unit CB1, CB2 integrating at least one control module (10, 11) of the state of charge and state of health SOC, SOH of said batteries B1, B2 which feed respective networks (17, 18), a first one of them (17) integrating security and supervision or stand-by modules, and the second one (18) including at least one start up device, power being distributed to said networks (17, 18) from power distribution boxes SDN1, SDN2, SDN3 which include a management microcontroller (1, 2, 3), and the system integrating a communications bus (19), characterized by carrying out permanent monitoring of the state of health (SOH) and state of charge (SOC) of each one of said two batteries B1, B2 and of the voltage or polarity of the external supply susceptible to being connected to one of the posts of one of said batteries B1, B2, and by carrying out an actuation by means of microcontrollers for ensuring a power transfer between said two batteries B1, B2, at any time.
