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.
