SYSTEM DESCRIPTION
• Battery current sensor (With battery temperature sensor) measures the charging/discharging current of the
battery and the temperature around the battery.
• IPDM E/R judges battery condition according to the charging/discharging current of the battery and the tem-
perature around the battery.
• IPDM E/R calculates the target power generation voltage according to the battery condition and sends the
calculated value as alternator voltage request signal to ECM via CAN communication.
• ECM transmits alternator voltage request signal to alternator via LIN communication.
• Control module inside alternator controls the power generation voltage based on the received alternator volt-
age request signal.
• Alternator includes a self-diagnosis function and transmits the diagnosis result to ECM via LIN communica-
tion when detecting any malfunction.
