Abstract: Method for diagnosing and predicting the lifespan of lead-based batteries, especially lead-based batteries intended to store standby power.
The invention essentially consists in a new method for diagnosing lead-acid batteries and advantageously for estimating their remaining lifespans, the batteries more particularly being intended for standby storage applications.
The method is based on a combination of continuous monitoring measurements with integration of the over-charging current (computation of the over-charging Ah applied to the battery from its installation) and of periodic measurements under DC current of the internal resistance of the battery using short discharging periods with a constant current or a constant power.
