Abstract
The method of recalibrating an energy management processor of a battery of accumulators consists, at the end of a defined period of time, in initiating a process of recalibration of evaluation of the quantity of electrical energy contained in the battery, in completely recharging the battery, in detecting the end of the complete recharge of the battery, in performing a partial discharge of the battery, in measuring the quantity of electricity extracted during this discharge, in leaving the battery to rest for a defined time, in totally discharging the battery at a low current while measuring the quantity of electricity thus extracted from the battery, in adding the said two quantities of electricity measured in order to obtain the value of the maximum capacity of the battery at the moment of the recalibration.
