Abstract
An apparatus and method for HVIL monitoring and control of an abnormal condition may be included to pass through a plurality of high voltage connectors of a battery pack, and inadequate electrical continuity of the HVIL may be identified with HVIL main power as the HVIL signal. If an abnormal condition exists in the HVIL (e.g., an open circuit), the HVIL main power may be switched to localized HVIL auxiliary power by a controller to individually check each connector for HVIL signal continuity. Each connector may be independently supplied with HVIL auxiliary power localized to the connector, to identify the state of that connector. Application, for example, to an electric vehicle, to differentiate between a potentially hazardous disconnect in a battery pack and a faulty low voltage HVIL signal line while driving to initiate safety control, if appropriate, enables a safer driving environment and experience.
