发明名称 METHOD FOR ESTIMATING THE STATE OF HEALTH OF A BATTERY
摘要 The invention relates to a method for calibrating a battery that makes it possible to store calibration data linked to the state of health thereof, characterised in that it comprises the following steps: E1: determining at least one characteristic state of the battery that is intermediate between its full charge and its full discharge, by detecting a peak in the evolution of the derivative of its no-load voltage during a charge or discharge of the battery, or at least one characteristic state of its full charge or full discharge, or defined by crossing a voltage threshold or a current threshold, respectively, during an imposed current phase or an imposed voltage phase, respectively, during a charge or discharge of the battery; E2: defining a reference state of the battery from this characteristic state; E4-E7: measuring no-load voltages OCVi of the battery in the reference state for a plurality of separate states of health SOHi and storing said calibration data comprising at least pairs of real values of the state of health/no-load voltage (SOHi, OCVi) in an electronic memory.
