INTELLIGENT BATTERY SENSOR FOR VEHICLE AND METHOD OF STORING DATA IN SENSOR

摘要

Provided is an intelligent battery sensor for a vehicle which detects an overcurrent module generating an abnormal overcurrent within a vehicle. The intelligent battery sensor for a vehicle includes a data packetizing unit configured to extract internal data variables related to detection of an overcurrent module and packetize the extracted internal data variables, a volatile memory configured to temporarily store the packetized internal data variables, a fault and validity diagnosing unit configured to monitor the packetized internal data variables stored in the volatile memory and classify, when a diagnostic trouble code (DTC) related to the abnormal overcurrent is diagnosed, the packetized internal data variables with respect to a diagnosis time of the DTC, and a nonvolatile memory configured to store the classified internal data variables under the control of the fault and validity diagnosing unit.
