P1449 Audi Description
The high-voltage battery in the IMA (integrated motor assist) system is designed to operate within the upper and lower limits of the SOC (state of charge) voltage and the battery capacity limits. When the battery deteriorates, the voltage is subject to an increase or a decrease, so the limits of the battery capacity is narrowed. Therefore, if the upper and lower limits of the SOC are detected when driving, the BCM (battery condition monitor) calculates the sum of the current and calculates the battery capacity. If the power is less than a set value, a malfunction is detected and a DTC is stored.
