Troubleshooting determine methods of electric bicycles

Electric bicycle repair it and, like a doctor, the first fault diagnosis, fault phenomenon through analysis supplemented by the necessary means of checking to determine the root causes of the fault lies, and then prescribe the right medicine, depending on the cause of the malfunction, adopted different tactics. Common fault diagnosis method summed up as follows: the use of the unique characteristics of the fault directly determine the cause of Electric scooters. Some electric cars such as the brake does not start, you need to manually reset the brake to work properly, this phenomenon is obviously caused by poor braking to reset, so long as the flexibility to reset the switch to eliminate the fault. Check the key point, and gradually narrow range. Different problems can cause the same fault, the same fault phenomenon may be caused by various Electric folding bikes, such as a battery problem can be caused by abnormal motor rotation, the controller will cause the motor rotation abnormal aging, motor internal fault will cause abnormal motor rotation, imaginary line even then turn will cause the failure of the motor rotation is not normal, as soon as possible to identify the cause of the fault must first check the key node parameters to determine exactly which part of the problem: for example, the power to determine the motor itself part of the problem or issue, and then do further examination to determine to determine the specific cause of the fault. According to the fault associated phenomena determine the fault site. When some failures occur, accompanied by other phenomena, which can be used as a basis to confirm the point of failure. For example, the same motor intermittent rotation lock switch caused the lights all went out with the phenomenon, if it is caused by low battery voltage is displayed under voltage. According to the law and to determine the frequency of failure of the fault location. Failure is based on the length of time intervals to determine the approximate location of the fault, for example, is also a gap between the motor rotation is stopped due to low battery voltage with regularity, intermittent rotation of the motor controller causes no regularity, or just do not hit the road will appear to stop. By measuring specific parameters to determine the fault location. By measuring certain parameters, to infer the fault location. Under such circumstances phase brushless motor, can be determined by measuring the Hall voltage motors inside the controller problem or issue. Substitution method to determine the scope of failure. For some soft failures, bad checks, instead of using a good device suspected faulty device, to see whether the fault elimination. Determine the cause of the fault according to the principle. Some faults, in different locations, different principles formed can be distinguished from the principle. For example, turn the controller failures and breakdown can cause a brush motor coaster, is to determine the fault location, you can use the brake to brake, if the brake power failure, it is very likely that a controller failure, because control is normal, the braking power should be valid.
