A charging system consisting of two batteries connected to each other, which is executed by a heavy vehicle and a heavy vehicle

摘要

A charging system of a pair of batteries mutually connected in series of a heavy vehicle, the system comprising at least one alternator (G3) connected to a vehicle electrical power supply system, the pair of batteries (Bl, B2) being mutually connected in series (B1+B2) and to the vehicle electrical power supply system, monitoring means (S) for monitoring a charging voltage (Vtot) of the series of batteries (B1+B2), processing means (VCU, ECU) suitable for interfacing with the monitoring means (S) and configured to control the at least one alternator (G3) so as to vary a respective supply voltage, wherein the processing means (VCU, ECU) are configured to command the start of a charging process of the series of batteries (Bl + B2), when a difference between the respective voltages exceeds a first predefined threshold value and to command the interruption of said charging process when a derivative of a current absorbed by the series of batteries (Bl + B2 ) exceeds a second predefined negative threshold.
