As a car charger buyers, you know where the car charger is easy to have problems?

One is carrying capacity risk source. Buck chips are critical to the safety of on-board chargers. If the use of inferior step-down chip, once the requirements of large current charge, will be because of the load impedance is too small, resulting in car charger output short circuit, approximation, the heat loss greatly, resulting in circuit breakdown or internal fire.  

Two is the overvoltage intensity risk source. If the circuit design is unreasonable, the car charger will be unable to withstand excessive voltage and puncture fever, may ignite. Due to the lack of sampling resistance, the test sample can not correctly judge the input voltage, and the output has no current limiting, resulting in a great deal of heat loss and causing fire.  

Three is the shell flame retardant risk source. High flame resistance of shell is a very important safety performance index for vehicle charger. At present, the car charger on the market all use plastic as shell material, and the low flame retardancy of plastic material can not prevent the flame from spreading in a certain environment, such as internal fire. The test showed that the samples after plastic shell flame has burned beyond recognition, basic.  

        Four is the normal temperature rise risk source. Due to long hours of sunshine and other reasons, the temperature in the car will continue to rise. In the case of long time high temperature, the performance and life of internal components are generally reduced. Test results show that the multi - interface and high current car charger is likely to produce excessive temperature rise in high temperature environment, causing internal device damage or indirect burns and other accidents.  

        Five is the output short-circuit risk source. Car charger power interface positive portion of small volume, most of the use of metal spring and metal cylinders composed of positive and negative power distance is very close, easy to cause the power input circuit, if not equipped with protection device, normally will affect the vehicle power supply system, even a serious accident.  

Six is the risk source of the protection device. The protection device is suitable for timely treatment of all kinds of unexpected faults, and the first time to cut off the input lines can avoid the potential harm caused by overvoltage or overcurrent. The risk monitoring found that more than half of the car charger does not install protective devices or selected protection devices, unreliable or protective devices installed improperly.
