COMPREHENSIVE METHOD OF ELECTRICAL FLUID HEATING SYSTEM FAULT DETECTION AND HANDLING

摘要

A method and system are provided to eliminate the risk of over temperature concerns associated with electrical heating devices, which if undetected may result in an electrical over temperature condition. The electrical heating system may be applied to the detection and control structure of other automotive electrical loads where thermal concerns may exist. The electrical heating system combines several layers of fault detection strategies, to form a unique comprehensive approach to prevent and detect potential electrical fault conditions, which if undetected and/or controlled may result in an electrical over temperature condition.
