How to Solve Electric Vehicle BMS Faults?

[VonTimothy]

bms fault solutions: 1. Observation method: When communication interruption or control abnormality occurs in the system, observe whether each module of the system has an alarm and whether there is an alarm icon on the display screen, then troubleshoot the phenomenon one by one. 2. Fault reproduction method: The faults that occur under different conditions of the vehicle are different. When conditions permit, try to reproduce the fault under the same conditions to confirm the problem point. 3. Elimination method: When the system experiences similar interference phenomena, each component in the system should be removed one by one to determine which part is affecting the system. 4. Replacement method: When a module exhibits abnormalities in temperature, voltage, control, etc., swap the positions of modules with the same number of strings to diagnose whether it is a module problem or a wiring harness problem. 5. Environment inspection method: When the system fails, such as the system cannot display, do not rush to consider in-depth, because some details are often overlooked. First, check the obvious things: whether the power is connected, whether the switch is turned on, whether all the wiring is connected, etc. Perhaps the root of the problem lies therein.
