Must comply with the operating requirements of the electric bicycle. The design standard load of electric bicycle is 75 kg. When the load exceeds 90 kg, the battery and motor will be damaged.   Batteries cannot be shelved for a long time, shelved at least once a month to charge. Battery discharge must be fully…

Because of the different commutation mode, the brushless motor and brushless motor not only have different internal structure, but also have great difference in connection mode.   1.The connection method of brush-motor. There are two lead wires in brush-motor. Generally, the red wire is the positive pole of the motor, and the black line is…

Market research shows that the ranking of electric vehicles is determined by various factors, such as feedback from the market for many years, consumer awareness, and future development status. We will objectively and impartially evaluate the famous brand in the current industry from the aspects of quality, sales, advertising, development potential, and development speed and…

Electric bike are favored by consumers because of their advantages such as portability and non-pollution. Driving mileage is one of the main standards for consumers to measure the quality of electric bike, and battery is the decisive factor in exercising the mileage. Among the numerous complaints about the quality of electric bike, the battery problem…

During the high temperature season, the storage battery is overcharged. When the battery temperature is increased, the activity of all active substances increases, the oxygen evolution potential of cathode decreases, and the oxygen evolution potential of negative electrode also decreases (minus value). Therefore, when charging, the charging speed is fast, the charging current is large,…

¡¡¡¡Electric bike front wheel is usually made up of three parts: outer tire, inner tire and cushion belt. ¡¡¡¡There is also no need for inner tube, the inner layer of its body has good air-tight rubber layer, and need to be equipped with special rim. The structure of tires all over the world develops towards…

Although electric vehicles have been loved by many consumers , it has become an indispensable step - in - step tool in people ' s lives , but now the brand of electric vehicles is numerous , and the product configuration is uneven , so it is important to choose a high - quality electric…

The first important parameter is the low constant voltage value in trickle stage, the second important parameter is the high constant voltage value in the second stage, and the third important parameter is the conversion current. These three important parameters are related to the number of batteries, relating to the capacity ah of the battery,…

The charging depth of battery has a great influence on the cycle life, which is due to the low binding fastness of the positive electrode active substance pb02, which is converted into pbs04 during discharge and then converted into pb02 when charging. The volume of pb02 is much larger than that of pbs04 (the volume…

According to industry sources, when the temperature is too low to minimize the use of electric vehicles, and should be charged in time.   If a user is not ready to use an electric battery in the winter, the battery should not be recharged until the following year, but should be recharged every other month…

¡¡¡¡The electric bike wheel is one of the most important components in the car, and its main functions are as follows: ¡¡¡¡Support the full weight of the vehicle, bear the load of the electric bike, and transfer the force and torque in other directions; Transmission of traction and braking torsion, ensuring good adhesion between electric…

Electric bike do not need a driver's license and many other trouble, the cost of use is relatively low. Electric drive is more environmentally friendly than gasoline, and has a relatively low speed. It can enjoy the leisurely fun and is more suitable for the elderly and women.   There are three advantages:   Frist,…

In recent years, the so-called three-stage charger is widely used in electric vehicles. The first stage is called the constant current stage, the second stage is the constant voltage stage, and the third stage is the trickle stage.   From the point of view of electronic technology, the first stage is called charging current limiting…

Understanding the basic requirements of battery charging technology is the basis of analyzing various charging technologies. The basic requirement of battery charge is that the charge current should be less than or equal to the battery charge current. If the battery is protected correctly, it's the best electric bike conversion kit. Otherwise, excess current will…

E-bike r charger is a device to charge the battery. If the output voltage of the charger is too low, the battery charging will be incomplete, which will naturally affect the battery miles. The mileage of a typical e-bike is proportional to the time it takes to recharge, which means that the farther the electric…

Everyone knows that the electric bike is simply driven by electricity. It uses electricity as an energy vehicle. Electric bike can be classified into electric bicycles, electric motorcycles, electric vehicles, electric tricycles, fuel-powered dual purpose electric vehicles, etc. In these electric vehicles and the people are closest to electric bikes and electric motorcycles.   The…

Insufficient battery power: charge the battery   Poor contact of battery contact: adjust contact position or polish contact;   Motor internal carbon brush, wire, winding virtual welding, virtual connection: repair or replacement of best mid drive electric bike motor.   Bad contact between the safety tube and the seat in the battery box: adjust or…

Lead-acid batteries have a history of more than 100 years, the beginning of the world's common along the point of aging and operating procedures: charge, discharge rate of 0.1 c is the battery capacity) longer life.   In order to solve the problem of rapid charging, American Mr. Max published his research results to the…
