How to solve Error Code 58

Fault code:【58】BMS communication failureReason:1. Abnormal line connection: The CAN signal line is loose, the pin is withdrawn, or the plug is not tightly inserted, resulting in signal transmission interruption.  2. Power supply issues: Voltage fluctuations or DCDC module failures can affect communication stability.  3. Electromagnetic interference: Ground loop noise or electromagnetic interference affects signal quality.  4. Software/hardware failure: BMS main control module program abnormality or hardware damage (such as CAN transceiver failure).     Solution:1. Basic investigationCheck all wiring for looseness, corrosion, or breakage, unplug and secure again.  Measure the CAN-H/CAN_L voltage (normal value 2.5V ± 1V) and confirm if the terminal resistance (total resistance of approximately 60 Ω) matches.  2. Environmental optimizationEnsure that there are no strong electromagnetic interference sources around the inverter and install shielding measures if necessary.  Check the stability of the power supply voltage and replace the DCDC module if necessary.  3. System level processingIf software issues are involved, the CAN driver configuration (such as baud rate, frame format) can be checked through programming tools.  If it is a hardware failure, the damaged CAN transceiver or main control module needs to be replaced.4. Safety adviceBefore operation, the power must be cut off to avoid the risk of electric shock.If it is difficult to handle on your own, it is recommended to contact professional personnel for maintenance.  Note: Please do not dismantle the machine without permission, otherwise it will be out of the warranty of Ktech.
