When we think that the electric vehicle charger will be under charged, we can charge it to the "slightly changed" state first, and then continue to use the ordinary charger to charge. If charging can continue, it can be determined that there is no fault in charging.

When we suspect that the electric vehicle charger has experienced charging failure, we can first use the normal charger to charge it to the "on" state, and then use the charger that may have problems to continue charging. If the charger of electric vehicle fails, and the charger has failed to charge, what should we do.

Excessive power consumption of electric vehicles can be detected by measuring the current consumption of electric vehicles while driving. Through the above simple judgment method, we can judge whether the charger is faulty.

Electric vehicle manufacturers and electric vehicle manufacturers remind more people to pay attention to:

Charger problem: in order to reduce costs, many electric vehicle manufacturers of miscellaneous chargers use circuit boards and internal electronic components with poor quality, easy to damage and high or low charging voltage. Using this kind of charger will inevitably affect the service life and mileage of the battery.

Controller problem: some controllers are of poor quality. Due to incorrect workmanship, control panel and parameters, excessive current, undervoltage value offset, etc., the "control effect" of battery power will be affected, resulting in shortened mileage and early termination of battery life. The battery is normal, but you can't drive too far. Do you know why?

Brake power failure: if the brakes do not return to this position by accelerating and adjusting the speed, they will "run" together with the brakes, which will waste a lot of power in the "fatigue work" of the entire vehicle components! If there is no brake power failure, please release it for repair, which has higher safety and can also prolong the battery life.
