Maintenance of common troublesAs the input circuit of the electric vehicle charger works in the state of high voltage and too high current, the fault rate is the highest. Such as high voltage high current transistor, rectifier filter capacitor, power switch tube; the second is easy to damage is part of the output rectifier diode rectifier, diode protection, filter capacitor, a current limiting resistor; then the PWM controller and feedback protection circuit.1. fuse tube fuseIn general, fuse tube fuses indicate that the internal circuit of the charger has a short circuit or overcurrent fault. ...

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...
