Photocoupler Nowadays, the number of battery cars is arguably more and more, and the damage of battery chargers accounts for a large proportion of all faults. However, the general charger has no circuit diagram at random, which causes great trouble for maintenance. Now, several representative charger circuit diagrams are extracted and shared by everyone.
Materialise, a Belgian 3D printing company, recently developed a 3D printed version of the Bicicletto electric bike in cooperation with the Italian car brand Nuova SPA. The advanced Bicicletto, the first product of the two companies, has many 3D printed parts that are not only more advanced in manufacturing technology, but also make electric bicycles lighter, faster and more cost-effective. Founded in 1906, Nuova SPA is a car brand based in Turin, Italy. Renowned for designing and manufacturing...
In fact, if the charger used at the beginning is of good quality, the charger can be used until your electric car breaks. If you don't want to waste money later, you have to prepare for it in the early stage. My recommendation is that several of the products under the high standard are not bad, and many electric vehicle manufacturers are also working with the high standard. So how to judge the failure of the electric car charger, the following steps are basically the repair personnel will...

The charger is a device that supplements the electric bicycle battery with electrical energy. It is mainly composed of rectification and filtering circuit, high voltage switch, voltage conversion, constant current, constant voltage and charging control. The purpose of the rectification and filtering circuit is to convert the 220V AC voltage of the mains into a voltage of about 300V DC. Through the high voltage switching circuit and voltage exchange, the low voltage DC voltage required for...
1. The fuse tube is blown In general, the fuse tube is blown to indicate that there is a short circuit or overcurrent fault in the internal circuit of the charger. This is because the charger operates for a long time under high voltage and high current, and the internal device has a high failure rate. In addition, fluctuations in the grid voltage, surges will cause the current in the charger to increase instantaneously and the fuse will blow. Maintenance method: First carefully look at the...

Pure electric vehicles use lithium batteries as the power source. When they are fully charged, they use electric power to promote their cars. Unlike gasoline engine cars, which need to add gasoline, pure electric vehicles charge them through an external power source after the power is consumed, usually with a single mileage of 100 to 200 kilometers. Compared with traditional cars, pure electric vehicles have an unparalleled advantage in terms of cost of use. They consume about 15 kWh per 100...
