- Q: Are the transmissions for electric bicycles and electric motorcycles the same?
- Divided into brush motor and brushless motor controller, that is, voltage and power difference
- Q: Recently want to buy electric cars, car, fancy pigeon and green.Wonder：1., with the foot of the electric car (to prevent electricity), the general speed can reach?2. how much distance can I charge once?3.2000, can you fix it?2000 refers to the price.Does the country have a regulation that the speed of electric cars can not exceed 20 per hour? Will it be dangerous after 20?What's the difference between 36V and 48V? Speed?
- Now the electric car prices generally lower, 36V 2000RMB no problem, 48V can buy 48V, but also good to 3000RMB, but this is a reference, buy time to compare the battery Ma, general 10Ah and 12Ah, better performance of 12Ah many.
- Q: How to choose electric bicycle?
- Two options: one is the home without storage conditions, and live upstairs, the car is afraid of losing, you have to carry the car upstairs
- Q: Relationship between voltage, speed, motor power and mileage of electric vehicle
- Obviously, the latter (72V20AH's battery) has a longer battery life than the former (60V20AH's battery) because the latter has relatively large power supply
- Q: See the electric wheelchair's motor is that kind of long, still connect a square box, but the electric bicycle's single machine is very small, but this is why? Is it the cause of the cost or the driving force?What are their respective powers?How much are their prices?
- Therefore, the electric wheelchair motor connected to the gearbox is the driving force, and the electric bicycle is brushless motor, and he requires speed, braking torque is small, there is no speed reducer, it looks small,
- Q: How to pick electric bikes?
- 2., the location of the battery, from the vehicle balance and get off easily consider, to the battery placed in the frame, inclined tube or vertical pipe position is good, the configuration of the battery is basically an affordable lead-acid batteries. At present, most electric bicycles adopt 36V12ah lead acid batteries; 24V12ah batteries have fewer consumers because of the shorter mileage.
- Q: All the questions about electric cars
- Controller fault (brush) (2) Troubleshooting: speed control, if normal, indicating that the controller is normal, you should check the speed control, and the ground. Disconnect the speed control, the car still does not stop, then the controller is damaged, replace the controller. If a power supply wheel will turn, increasing speed is very fast, commonly known as "speed", the majority of the turn of the ground contact is caused by bad cycle. Therefore, the key to check the turn to the ground. 8, instrument panel no power display, motor operation is normal (1) fault reason: instrument positive and negative lead wire, no voltage, lead or connector short circuit. Instrument damage. (2) Troubleshooting: use the multimeter DC 50V files, detect positive and negative voltage instrument. If the voltage is normal, the instrument is damaged. Without voltage, wires or connectors are broken open, and cables and connectors are checked. 9, the instrument voltage shows normal, speed display abnormal, motor operation is normal (1) failure reason: instrument damage. Speed signal line (black / white) short circuit. The controller has no speed display. (2) Troubleshooting: brush and brushless 48V: using a multimeter voltage blocking detection speed signal line and a power supply cathode (48V brushless speed signal detection and negative) between the two potential with the motor speed, the voltage varies from low to high (36V models have 0 ~ 36V change, 48V brush 0 the change of 48V ~ 48V brushless, it varies from 0 to 25V). If there is no change, check whether the speed signal line plug is normal or not Is there a short circuit? If the voltage change is normal, it belongs to the instrument fault, for example, the speed display is low. The speed adjustment potentiometer can be adjusted to the normal by the screwdriver. 36V brushless: first check the instrument panel and controller speed line (black / white), the connection line is short circuited
- Q: How to maintain the battery of electric vehicle?
- Fourth, the car does not use batteries for a long time, a Zhou Chong, a power. (for two or three months without recharging, the battery is going to waste.)Fifth, cycling should pay attention to, generally take the start, climbing, manpower help line, without overloading, do not drive fast, often charging.Six, battery vulcanization is the first killer of battery life.Vulcanization is a battery that produces lead sulfate particles during charging and discharging, especially in large current discharges. For example, if the 10Ah battery, with more than 10A current discharge will produce more lead sulfate particles in cathode materials, this reaction is irreversible reaction in electric current conditions and charging mode, with the extension of time, the particles in the electrode material on the accumulation, because the particles are not conductive, the resistance of external characteristics of the show is to increase the battery, reducing the capacity, cause the whole group battery capacity decline, large current discharge capacity (the actual performance is climbing ability) to further reduce. This phenomenon is called the vulcanization of a battery. Once the battery is vulcanized, it will not only reduce the capacity of the negative plate of the battery, but also aggravate the loss of water and the softening of the positive plate, which will affect the life of the whole battery.
- Q: How to maintain the motor of electric vehicle?
- This makes the battery performance quickly damaged, seriously affecting the battery life. How to prolong the service life of battery? First, the car to light, better performance. Using simple models of battery life style is relatively long, because the wheel diameter, light weight, battery light burden. And some cars using brushless motor or high-speed motor, discharge current is smaller, such a car at 20 kilometers per hour cruise current is about 4a, this kind of car life is relatively long. Second, the battery should choose a good quality brand. Third, choose a good charger. The popular phrase is: battery is not bad, is full of bad. Therefore, the charger should be used well. Fourth, the car does not use batteries for a long time, a Zhou Chong, a power. (continuous two to three months without charging, the battery will be abolished) fifth, cycling should pay attention to, generally take the start, climbing, manpower help line, without overloading, do not drive fast, often charging.
- Q: Can minors drive electric cars? What about electric bikes?
- Must be 16 years of age. Electric vehicle rules, please refer to:1) electric bicycles should not be manned;2) must be in the non motorized lane running, no non motorized lane, just on the right side of the road;
