- Q:Electric car brush and brush, how simple distinction?Buy BrushlessDon't tell me what line to look at. What should I see when I buy it? How can I make a simple distinction?
- The brush motor adopts mechanical reversing, the technical requirement of the control system is lower, the relative cost is lower than the brushless motor, and the starting torque of the brush motor is slightly larger than the brushless motor. But the fatal weaknesses are short life, high noise and low efficiency. Its long-term use of carbon brush, serious wear and tear, easy to damage. At the same time, a large amount of carbon dust is produced, which falls into the gear oil to accelerate the drying of gear oil, and further increases the motor noise. There is a brush motor use about a year, you need to change the carbon brush, you will find that charging mileage is less than 2/3 of the new car bought, but also lack of power when climbing, but also burn the controller. This is because the motor to replace the carbon brush, commutator also grind a groove, reduce carbon brush contact area, poor contact power will produce sparks, and accelerate the oxidation of copper and lead to the commutator, bad phenomenon.
- Q:My small room and the distance is about 70 ~ 80 meters, my electric car is ordinary kind of Tianjin sunshine, 4 batteries, 48V, now want to take a little real power to the electric vehicle charging, do not know how many flat cable. Thank you, the power house usually lighting and charging, I saw a 1.5 flat on the Internet, 2 core cable, but the copper alloy do not know can not be used, please, professional advice.
- First，From various safety requirements,220V AC power lines should not be hung outside the wall,Even a low voltage line,Hang down from the top floor,The cross sectional area of the wire and ordinary telephone wire is too small and the strength is poor,
- Q:Nowadays, electric bicycles and electric cars are becoming more and more popular. They all use motors to obtain power. The nameplate of a DC motor is marked with "220V 5.5kW"Now the electric bicycle, electric cars gradually spread, they are used to obtain power motor DC motor. A nameplate marked "220V 5.5kW, resistance motor coil is 0.4 ohms.
- Answer: (1) this motor works normally, 1H, consume 5.5kW, h Electric energy;(2) the motor coil produces 9 * 105J of heat;(3) the coil is stuck and can not rotate, and the electric energy can not be converted into mechanical energy. All the energy consumed can be converted into internal energy, so a great deal of heat is produced and the temperature is raised rapidly

- Q:Electric cars do not turn electricity on the matter
- 2., the second case is the power switch is broken, replace the power switch. Judge: open the power switch, with a multimeter resistance between the input terminal and the output terminal of the power switch to measure ohm files, such as the resistance value of zero is normal, such as the resistance is infinite, then the power switch is broken, replace the power switch.3., the third kind is the Huo Huo turn, bad. The specific diagnostic method is to use the multimeter DC voltage files to measure the output of the turnThe output voltage of the green line will be normal if there is 1-4.2 voltage output. If there is no voltage output, the switch will be burned out, and the switch should be replaced.
- Q:Sometimes, when the key is not turned on, the car runs by itself! I hope to answer the professional point, thank you
- Electric cars run without electricity1, the electric car to turn the broken, check, replace the switch.2, short circuit of electric vehicles, inspection lines.
- Q:The body of an electric car is usually heavy, and the speed is not easy to control. How to drive an electric bike correctly? For different brands of electric bicycles, please briefly introduce the operation methods and precautions for safe driving.
- Charged immediately after the end of the ride or battery runs out. It is forbidden to charge the battery in the case of upside down, otherwise it will seriously affect the service life of the battery. When the charger's input and output are connected, the green indicator light of the charger will light up to indicate that the power is on. Charge 2 to 8 hours, the red light, said electricity has been basically full, then float 1 to 2 hours, remove the power socket. General charger has overcharge protection device, long time charging (usually not more than 24 hours), generally does not affect the service life of the battery.
- Q:Is the electric bicycle battery charged well or is it not necessary to recharge it?
- Use 70% to charge well. The new electric car, the first to the third charge, it is best to use 70-80% electricity again enough, the time should be two hours after the lights change. Usually more than 12 hours, and later can be used as soon as possible.
- Q:How do electric cars ride the most electricity?There is an electric car at home, and every time it is finished, it is not enough.
- 4, completely off the electric charge is not correct, the greater the depth of discharge, battery life is short; 5, if you do not use electric bicycle long time, should pay attention to put on battery charging, monthly check quantity; 6, if not the electric motor, is best not to add security device, effect, and increase the burden on the battery; 7, if you ride the distance is about 15 kilometers, estimate your battery can be used for 2 years; 8, if you find the battery is too hot, don't charge! Go and repair it at once.
- Q:New electric cars to maintain, such as the speed of cycling. Charge。 The new chain needs no oil.
- Protect the charger.The general instructions for use include instructions on how to protect the charger. Many users do not read the instructions of the habit, often in addition to the problem after thinking of looking for instructions, often too late, so the first look at the instructions is very necessary. In order to reduce the cost of the charger, now basically no design, high vibration resistance so that the charger is generally not on the electric bicycle and bicycle in the trunk. Special circumstances, you must move, but also the charger wrapped in foam plastic, to prevent vibration bumps. Many chargers after vibration, the internal potentiometer will drift, so that the entire parameter drift, resulting in abnormal state of charge. In addition, the need to pay attention to when charging is to maintain the ventilation of the charger, otherwise, not only affect the charger's life, but also may occur thermal drift and affect the charging state. This can cause damage to the battery. Therefore, it is also important to protect the charger.
