How to choose to produce electric car charger, in daily life, when the electric car charger broken, many people will buy a random, but different models of electric cars, electric car charger is not common. Here are some tips for choosing an electric car charger. In order to know whether the electric vehicle charger has the core technology, the common electric vehicle charger uses the three-stage charging mode, in the charging process easy to appear overcharge, undercharge and so on phenomenon, affects the electric vehicle service safety and the service life. The charger of Hongju Electric vehicle adopts switching power supply technology, CPU control and pulse width modulation (PWM) technology, PFC power factor correction, zvs soft-switching circuit to precisely control the charging current and output voltage of the charger to ensure full charging, avoid overcharging the battery, protect the battery from the source, extend the battery life. Take a look at the appearance of the electric vehicle charger, the case is not Refractory, the circuit board is not fire resistant, there is no overheating protection, the plug socket quality is poor, the component quality is low, the input line quality is poor, the outer sheath core is exposed, the input and output spacing is insufficient, it doesn’t meet the safety requirements. These problems are not easy to be noticed by consumers, is the fundamental quality of products, but also lead to electric vehicles electrocution, fire and even an important factor in explosions.

　　Look at the performance of electric car chargers, giant electric car chargers features: 1. Fully automatic, impact charging, flat charging, trickle charging (Lead acid battery) , fully automatic shutdown (lithium battery) , no manual intervention in the charging process. High precision current-voltage lock ensures full charge, but 3 times. Over-current, over-voltage, short circuit protection, safe and reliable. High stability, switching power supply control chip using imported military-grade integrated circuit, stable and reliable, low failure rate, high reliability, the average life of 50000 hours above 5. Using switching power supply circuit, using pulse width modulation technology, PFC Power factor correction, conversion efficiency 90%-98% , power factor greater than 0.9, efficient environmental protection 6. Indicator light display, all-aluminum housing, beautiful and durable, low ripple coefficient, and other small electromagnetic interference equipment. European CE, Japan pse, rohs certification, safety certification, export quality 8. Patented Technology, Quality Assurance, one-year warranty, users worry-free 9. Small volume, light weight, reasonable structure, heat dissipation design, improve the portability of the charger
