Abstract

L'invention porte sur un procédé de surveillance thermique d'une batterie de traction d'un véhicule automobile associée à au moins un calculateur de contrôle, le véhicule étant dans une phase de stationnement et le calculateur de contrôle étant dans une phase de veille, ledit procédé comporte: - une étape (200) de mesure en permanence d'une température de la batterie de traction et/ou d'une température externe, - une étape (201) de comparaison de la température de la batterie de traction et/ou de la température externe avec un seuil de température correspondant, et - une étape (202) de déclenchement d'un réveil du calculateur de contrôle dans le cas où a été détecté un évènement thermique anormal lié à une atteinte ou un dépassement d'un seuil de température. Figure 4The invention relates to a method for thermal monitoring of a traction battery of a motor vehicle associated with at least one control computer, the vehicle being in a parking phase and the control computer being in a standby phase, said method comprises: - a step (200) of permanently measuring a temperature of the traction battery and/or an external temperature, - a step (201) of comparing the temperature of the traction battery and/or or the external temperature with a corresponding temperature threshold, and - a step (202) of triggering a wake-up of the control computer in the case where an abnormal thermal event linked to reaching or exceeding a temperature threshold.
