BATTERY MANAGEMENT SYSTEM TEMPERATURE HARDWARE SOFTWARE FAIL DETECTION DEVICE OF ELECTRIC VEHICLE

摘要

PURPOSE: An apparatus is provided to be capable of seizing whether a battery control part is broken, by discriminating a normal operating state of a temperature input terminal and an internal circuit of the battery control part. CONSTITUTION: A temperature detecting part(330) is connected between temperature input terminals and detects a battery temperature corresponding to each battery voltage value. A diagnosis part displays a battery temperature supplied from the temperature detecting part. The temperature detecting part includes connection lines corresponding to the batteries, a connector coupled with one side of each of the connection lines, and a temperature detecting circuit part for detecting a battery temperature corresponding to each battery voltage value.
