- according to "weekly quality report" ReportIn April, a car park at a university campus in Fujian burst into flames early in the morning, with hundreds of bicycles and electric bicycles burned and some burned to a skeleton. In front of the fire shed a plug for electric vehicle charging, there are many burned electric vehicles connect the charger, the fire department preliminary determination for the electric vehicle charging fire. Fortunately, the fire did not cause casualties.According to data from the electric bicycle industry, the probability of an electric bicycle fire every yea...

Since the invention of electric vehicle charger, with the continuous progress of technology, the charger has been updated several kinds. For the moment, pulse charging is the latest battery charging technology.If the electric car battery is the heart of the electric car, then the electric car charger is the electric hand and foot, the electric car without the charger is equal to no hands and feet, without energy, can not drive.The use of the technology produced by the electric car charger called pulse charger, which can charge the battery in the battery maintenance, thereby increasing the batt...

There are 6 main types of charger for electric vehicles, as follows:1 peak voltage control: to determine the end of the charge by detecting the voltage of the battery, the charge will be terminated when the voltage reaches its peak value.2, TCO control: when the battery temperature rises a certain value, stop charging.3 time control. This is the simplest form of charging control for an electric car charger. The charging end is controlled by setting a certain charging time, which is normally controlled according to the corresponding time required by the nominal capacity of the battery. Standard...

1 fuse tube fuseThe fuse tube fusing shows that the internal circuit of the electric charger has short circuit or over-current fault. This is because the charger for a long time to work in high voltage, high current status, the higher the failure rate of internal components. In addition, the power grid voltage fluctuations, surge will cause the instantaneous increase in the charger and fuse fuse.2 the DC voltage output is too highThis failure is often to voltage sampling and voltage control circuit is abnormal, in the electric vehicle charger, DC output, sampling resistor, error sampling ampli...
