A charger is an electrical device that recharges a battery. It converts electricity to direct current and controls its current and voltage to be stored in the battery. No matter what the charger looks like, but if it breaks down, your thousands of Yuan fat tire electric bike won't be able to ride without electric…

What is the function of the fat tire electric bike controller? The main function of the controller is to control the output current and voltage of the battery, and then to control the speed of the motor. Electric vehicle controller is the core controller to control the starting, running, moving, moving, speed, stopping and other…

Simply put, the role of an electric bicycle motor is to convert the chemical energy of the battery into mechanical energy, thus turning the wheels. That is to say, the energy of the battery can only be brought into play by the motor conversion, otherwise the fat tire electric bike can't run by the battery…

The function of battery is to provide the power source for fat tire electric bike, also is the energy carrier, is used to drive the electric vehicle motor. To put it simply, batteries are devices that provide energy and store energy for fat tire electric bike. A battery is a device for converting and storing…

The relationship between the components of fat tire electric bike is as follows: Battery is the core part of fat tire electric bike, accept the electric energy of charger, store it and output it by motor, output is controlled by controller. The charger is a kind of equipment directly connected with the battery. The quality…

What are the four major electric parts of fat tire electric bike? Generally speaking, the four major electrical components refer to 1: 1, controller 2, battery 3, motor 4, and charger. The role of batteries is a source of power for electric vehicles, energy carriers, used to drive the motor. Motor. The function of the…

An electric bike has various advantages: no emission more green, no sweat after long riding, no parking fee more convenient. Among them, fat tire electric bikes are becoming more and more popular nowadays. Compare with normal tire electric bike, fat tire electric bikes have the following benefits: It can bring u to more serious terrain…

The controller is one of the four important components of fat tire electric bike, so what effect does the controller have on the battery? The effect of fat tire electric bike controller on battery life is as follows: electric vehicle is a discharge process to the battery while driving, the controller controls a variety of…

The lack of phase in brushless motor of fat tire electric bike is caused by damage of Hall element of brushless motor. By measuring the resistance of the output lead of the Hall element relative to the lead of the Hall ground wire and the lead of the Hall power supply, the comparative method can…

When the temperature is 25 C, under the condition of standard test, the continuous mileage of the vehicle assembled by different forms of motor is different. We can refer to the data of the normal fat tire electric bike to determine whether the vehicle's mileage is normal. If the actual mileage is less than the…

The inspection methods are as follows: Turn on the fat tire electric bike power and turn on the knob to make the motor rotate above 10 s at high speed without load. After the speed of the motor is stabilized, the maximum no-load speed of the motor is measured by the hand-held speed / speed…

First, using a non-contact infrared thermometer, or a multimeter temperature measuring baffle (a multimeter with temperature measurement, measuring the temperature of the end cover of the motor above 25 ¡æ above the ambient temperature), indicates that the temperature rise of the motor has exceeded the normal range. The temperature rise of general motor should be…

While undercooling and overheating are not good for fat tire electric bike, they are generally more likely to be cold (electric vehicles tend to get 30 cents less electric power in winter than in summer, but are more afraid of moisture or water than cold ones.) Pay attention to sunscreen Although the fat tire electric…

The battery is first charged for general maintenance and then discharged at a 2-hour rate. During discharge, the voltage of the battery of fat tire electric bike is continuously measured, and the "backward" battery with insufficient discharge capacity is selected for treatment. Add 1.050 of dilute sulfuric acid until the liquid electrolyte appears, and then…

Avoid travelling on rainy days. When driving on wet roads, you can only keep running if the depth of water is no more than the center of the electric wheel. Once the water on the road goes beyond the wheel center of fat tire electric bike, it may cause the electric wheel to seep and…

The imbalance of series battery of fat tire electric bike is a worldwide problem, and there are always "backward" batteries in the process of use. Its reason is various: have production reason, also have the reason of raw material, and also have the reason that uses at the same time. At present, in spite of…

Reason 1: the inner bearing clearance of electric bicycle is large Treatment: replacement of bearings   Reason 2: motor rotor sweep Treatment: repair of stator, fat tire electric bike and rotor Reason 3: magnetic steel loosening Treatment method: rebonded magnetic steel   Reason 4: motor body deflection Treatment: readjusting the body   Reason 5: motor…

If the damage of integrated circuit is detected, it is necessary to replace the integrated circuit. Disassembly integrated circuit When disassembled, heat printed circuit board with flame of wine lamp to form circuit pin pad, move printed circuit board quickly and evenly until solder of all pads melts, remove integrated circuit board from printed circuit…
