Abstract: The management of a pool of batteries is an intelligent management taking account of the state of health of all the batteries of the pool and of the evolution thereof with time. The method for managing includes determination of priority criteria and charging of a battery selected according to the priority criteria. After the selected battery has been charged, electrical parameters representative of the battery are measured, then the state of health of the selected battery is analyzed according to the measured electrical parameters. The priority criteria are then updated according to the state of health of the battery. Selection of the next battery to be recharged is performed according to the updated priority criteria. The measured parameters used for analyzing the state of health are preferably representative of a coup de fouet effect during a partial discharge of a fully charged battery.

Abstract: The battery charging method uses a pulsed current alternately taking first and second amplitudes during first and second periods (t1, t2). At least one of the parameters, amplitude and duration, of the current during the first period (t1) is automatically servo-controlled as a function of a first value of the slope (P1) of the voltage (U), measured at the terminals of the battery to be charged. The first slope value (P1) is calculated at least at the end of the first period (t1). Likewise, a second value of the slope (P2) of the voltage (U) can be calculated at least at the end of the second period (t2) and at least one of the parameters of the current during the second period (t2) can be automatically servo-controlled as a function of the second slope value (P2). The different parameters of the pulsed charging current are thus continuously servo-controlled as a function of the voltage slope to keep the slope (P) within a range comprised between 1 mV/s and 6 mV/s.
