Message Time Limit Exceeded (CAN)

Was bedeutet 57 ?

The charger did not receive an expected message from the battery via CAN bus within the allowed time frame. This indicates a delay or loss of communication packets, leading to a timeout and a communication failure.

• High latency or an intermittent connection on the CAN bus, causing messages to be delayed or dropped.
• The battery's BMS is slow to respond to queries or experiencing internal processing delays.
• Incorrect timeout settings configured in the charger's CAN communication parameters, making it too aggressive.

1. 1

   Inspect the CAN bus wiring for proper shielding, grounding, and integrity to ensure reliable signal transmission.

2. 2

   Check the battery's BMS for any internal fault codes or indications of slow operation or processing overload.

3. 3

   Review the charger's CAN communication timeout parameters and adjust them if necessary to be more tolerant of network latency.
