What is the cause of the noise from the production of electric chargers?

What is the cause of the noise from the production of electric chargers? When oneself electric car charges, what reason is charger noise big? How to solve this problem, in fact, there are three reasons, now detailed. Radiator fan bearing oil, if the radiator fan bearing oil, when the charger works, the fan rotation will generate friction noise. Therefore, users only need to open the charger, find out the cooling fan bearings, add lubricating oil can solve the charging noise problem. However, it should be noted that if the bearing rust, the first thing is to remove the rust. The second thing we need to know is that electric cars generate a lot of heat when they charge, and that’s when the fans start to work to make sure the heat gets out. Charging an electric car at high temperatures can cause the charger’s cooling fan to speed up, which not only increases noise but can also burn out the charger. To solve this problem, users can simply stop in the shade to charge, and try to control the charging time, to prevent overcharging, can solve the problem of large noise.The components of the charger fall off, and a failure of the charger may result in increased noise. Why would you say that? When the parts of the charger fall off, the charging parameters change, the charging voltage is uneven, the temperature of the charger rises, and the cooling fan rotates abnormally, resulting in noise. For these problems, it is generally not recommended to reconnect the parts, but directly replace a new charger. High-power charger, in short, electric car charging, charger if the noise is very large, generally caused by the above three reasons. For the user, no matter what reason, must take the corresponding method promptly to solve, lest charges the bad battery. For the maintenance of electric car chargers, I have a few suggestions: do not try to carry a charger with the car, lest the vibration and parts fall off; for electric car charging is a better ventilation option; summer charging time control within 8 hours, winter charging time control within 10 hours; do not mix charger, do a charging car.
