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…

If the battery of electric vehicle is not in use for a long time or has been placed for a long time: please replenish the battery first; Tire pressure is insufficient: pump; Check whether the brake is too tight and friction rim: adjust the brake; Whether the battery charge is adequate: recharge; Whether meet the…

Remember never to add anything to your own shell. Chinese electric bike is expensive, so we need to take good care of electric bike. Once you remove the shell and add it to disturb the density inside, even if the repair shop equipment is very advanced, you can no longer extend the battery life, only…

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…

Fat Folding electric bike is always the sales champion in folding series. Equipped with comfortable but compact 20¡¯¡¯*4 tires, BestarMotor fat folding can be conveniently folded in order to store and transport more easily. BestarMotor has the abilty to take on many tasks you would not expect from a normal folding bike such as hauls…

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…

Whether the braking function of Electric bike is effective or not Electric bike brake power failure is not dispensable, but must be effective, this cannot be careless. It is understandable that users do not understand the relationship between the power failure of electric bike and the short distance of the china electric bike, and we,…

By measuring the supply voltage or signal voltage of the connecting parts or leads of the controller, we can analyze and determine the fault of the controller. Referring to the main phase check measurement diagram of the brushless controller, a multimeter DC voltage of 50v is used to detect the relationship between the gate voltage…
