It is herein described a battery monitoring system, in particular for a vehicle battery, which comprises the steps of: calculating, based on the battery voltage (1), the parameters of the battery state of health (SoH), battery state of charge (SoC) and stand-by current (IOD); comparing the battery state of health (SoH), the battery state of charge (SoC) and stand-by current (IOD) parameters with their previously established limits; and providing a warning sign when any parameter is different from its previously pre-defined limit. The system allows monitoring a vehicle battery (1) beginning from its installation and provides the driver indications about the necessity of maintenance or replacement thereof, exclusively based on the battery voltage, measured at specific times of the vehicle operation.

A method for diagnosing a lead-acid battery of an automotive vehicle includes an experimentation phase in which parameterization of the state of health (SOH) of a lead-acid battery for different values of the state of charge (SOC) of the battery is conducted, and a diagnosis phase in which the battery temperature during the start-up phase of the vehicle is measured and, after the first discharge and over a given range of current variation, the corresponding voltage (U) and current (I) is measured, to deduce therefrom after processing, a value of parameter (γ) of the battery. The state of charge (SOC) of the battery is then determined, and the value representing the state of health is determined, so as to establish a diagnosis of the battery.
