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...

A larger current will damage the batteryIt is better not to use the fast charger frequentlyIn the urban areas of many electric car maintenance department, or newspaper and magazine kiosks next to, there will be suchelectric cars, fast charging station, charging electricity every dayMany cars, of course, many people are convenient for the map, save trouble, fast.Electric car fast charging station can solve the electric carhalfway anchor "urgent matter", the general electric vehicle charger output voltage is 36 - 48 voltsThe principle of fast charge is to transfer the current to a fast...

Constant current charging of electric vehicle charger constant current charging means that the battery is charged with piecewise constant current charging method, and the current is adjusted by charging device to achieve. Its main feature is that the charging method has greater adaptability, and the charging current can be arbitrarily selected and adjusted. So it can be for different condition and battery state of charge (such as battery charging, battery charging at the beginning of the used and went charging). The utility model is especially suitable for charging small batteries with long cu...
