- Q: What types of electric bikes do you have?
- The electric bicycle can be divided into 18 inches, 20 inches, 22 inches, 24 inches, 26 inches according to the size of the wheel.According to the drive mode, it can be divided into chain drive, friction drive and shaft drive
- 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?
- Electric wheelchair mechanism. A long box reducer for electric wheelchair is using a brush motor, the motor speed per minute at 3000 rpm, while the electric wheelchair with the actual speed is 110 rpm, the braking torque in 50Nm, therefore we need to slow down and increase torque deceleration mechanism
- Q: How can I extend the life of an electric bicycle battery?
- AnswerMaintenance of batteries for electric bicycles(1) the battery should be firmly installed on the electric bicycle, so as to prevent the battery from being damaged by vibration when riding.(2) regularly remove dust and dirt from the battery box, and keep the battery dry and clean, so as to prevent the battery from discharging itself.(3) the battery should not be close to the high temperature heat source. High temperature season, strictly prohibited direct exposure in the sun (summer car storage should pay special attention). Pay attention to good ventilation when charging.(4) the electric bicycle has just started, to start with the pedal power to avoid excessive discharge current and damage the battery; when riding, be careful not to let the battery over discharge, over discharge of battery is easy to cause serious loss of electricity, thus greatly shorten its service life.(5) the carrying capacity of electric bicycles is too large, which will inevitably lead to the increase of motor current, lead to over discharge of batteries, and early decay of batteries, which will seriously affect the life of batteries. Our company has introduced high-power motors, large capacity batteries equipped with electric vehicles, the purpose is to solve the road trip often encountered large slope problems. But some consumers blindly pursue the carrying capacity of electric bicycles, especially cyclists, as shown in the following pictures, not only in violation of traffic laws, but also in the maintenance of electric bicycles themselves.
- Q: How long do electric cars usually charge at one time? How long will it last?
- Battery maintenance knowledge:1., when the car starts, do not force electricity, should be slow to accelerate, and pedal to power.2., on the uphill or against the wind, it is best to use the pedal to help, so that your batteries, motors are good.3. best when charging a one-time full, etc. the red light floating again after 1 - 2 hours.4., do not overload, overweight, driving, found that when the meter shows insufficient electricity, you should use human riding.
- Q: Buy electric cars need to pay attention to what problems?
- Seven tips: observe the appearance of defects not only affect the appearance of beautiful, and lead to shorten the service life and increase customer service cost. Such as: frame and front fork welding and surface defects, the manufacture of all parts is good, whether the double support is firm, and whether the plastic parts are defective or not.Eight Tips: try some new cars would be imperfect in the assembly, commissioning pay more attention to the brake is flexible; motor sound is normal, light and instrument is normal.Nine: Date asked the electric vehicle battery charging will not place long-term damage very quickly, the closer the better electric car battery factory date.Ten tips: good custody after the purchase of electric cars to the vehicle accessories, invoices, certificate, manual, charger, three packs of cards to collect and safekeeping. Some manufacturers have set up a user record system, please follow the instructions for the record, in order to enjoy after-sales service.
- Q: EABS brake principle of electric bicycle, is the brake depth good or small?
- EABS electronic brake system principle of electric vehicle1 、 design principle of EABS systemBrushless EABS system makes full use of the characteristics of electronic commutation of brushless system, and controls the different motion state of the motor by programming.At present, no mature way of control system for three-phase brushless motor six PWM driving mode, the 8 signal detection of the 3 Holzer element relative position of stator and rotor of the: 001, 010, 011, 100, 101, 110, 111, 000, two illegal state controller program to automatically delete: 000. 111, motor drive signals from the six signals.
- Q: What's the difference between electric cars 36V and 48V?! Detailed points ~ ha ha ~ thank you!
- 36V electric vehicles are generally using 12Ah batteries, basically are small models of electric vehicles, power between 220W-350W.
- Q: EV battery charging is hot, what's the reason?
- The reason of electric vehicle battery burns are the following: 1. after the end of a driving electric charge, a long time, the battery capacity is insufficient, to charge the battery, because the battery capacity is low, so when in charge, the current will be very large, the current will cause the charger and battery fever, but this belong to the 2. chargers and batteries do not match the normal phenomenon, caused by fever 3. battery time is relatively long, about a year of battery, battery has entered into the withering period, when charging, the battery will be very hot in the Xia Tianrong.4. prone battery hot phenomenon, because the summer temperature is high, then plus charging, so it was easy to happen. This phenomenon suggested in the summer with the battery charging time, kept in a ventilation state, do not use the charger covered in a charger also maintained under the condition of ventilation, In order to ensure the heat! Recommended that the use of electric vehicles, not to when no power, then to charge, because recharging when no electricity, the battery has a serious loss, will lead to the normal use of time and shorten the battery life, accelerate the aging degree! Recommended that the use of electric vehicles, as far as possible to do with used with the charge, with a full time, keep the battery in a saturated condition, to extend the battery life!
- 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: The car and the electric bicycle through the phase, electric bicycle belongs to the vehicle?
- Therefore, the electric bicycle in the end is considered a motor vehicle, according to the speed of the electric car and its own re - divided.
