Abstract
(EN) The present invention proposes method steps to monitor battery health of a vehicle. The method step 201 comprises cranking the vehicle at least two times within a duration of a minute. Method step 202, comprises recording a real time value of battery voltage with respect to time measured by the battery (102) voltage sensor (103) by the control unit (101). Method step 203, comprises comparing the said recorded value with a stored reference value. The stored reference value refers to a pre-determined values of battery voltage with respect to time. Method step 204, comprises indicating the health of the battery (102) based on the said comparison.
(FR) La présente invention concerne des étapes de procédé permettant de surveiller l'état de santé d'une batterie d'un véhicule. L'étape de procédé 201 consiste à démarrer le véhicule au moins deux fois au cours d'une durée d'une minute. L'étape 202 consiste à enregistrer une valeur en temps réel de tension de batterie par rapport au temps mesuré par le capteur de tension de batterie (102) par l'unité de commande (101). L'étape 203 consiste à comparer ladite valeur enregistrée à une valeur de référence stockée. La valeur de référence stockée se réfère à des valeurs prédéterminées de tension de batterie par rapport au temps. L'étape 204 consiste à indiquer l'état de santé de la batterie (102) en fonction de ladite comparaison.
