Abstract[English]
Method and apparatus for measuring electrical parameters of an EV for determination of insulation parameters. The method comprises: establishing data communication with the EV so that the vehicle is switched into a power exchange mode, which is a battery charging mode or a power export mode; measuring battery terminal voltages of the EV with respect to the electrical chassis of the EV via the power exchange port; and processing the battery terminal voltages, which are voltages measured with respect to the electrical chassis of the EV to determine isolation resistance and/or insulation status of the EV. The method and apparatus can facilitate safe and non-destructive or non-invasive measurement of insulation parameters of the live parts of the high-voltage electrical system of the EV.[French]
Procédé et appareil pour mesurer des paramètres électriques d'un VE pour la détermination de paramètres d'isolation. Le procédé consiste à établir une communication de données avec le VE de telle sorte que le véhicule est commuté dans un mode d'échange d'énergie, le mode d'échange d'énergie étant un mode de charge de batterie ou un mode d'exportation d'énergie; mesurer les tensions de borne de batterie du VE par rapport au châssis électrique du VE par l'intermédiaire du port d'échange d'énergie; et traiter les tensions de borne de batterie, qui sont des tensions mesurées par rapport au châssis électrique du VE afin de déterminer la résistance d'isolation et/ou l'état d'isolation du VE.
