- Q:An electric bicycle with a transmission. Is it still powered by a motor when it's powered by a human?
- The design of the hub motor is different from the conventional hub motor. It changes the traditional electric vehicle flat drive, but adopts the reducer and direct drive mode. The motor is built on a hub, which relies on the miniaturization and high efficiency of the motor, and has the advantages of high energy efficiency, expanding space utilization and high control performance,
- Q:What is the difference between non - zero start and zero start of electric vehicle?
- [] is zero start the electric car when the ride started direct start, does not need external forces to make the wheels move up, then slowly start, there is now the electric car basically no nonzero start.
- Q:How to prevent the electric bicycle fire caused by what causes?
- The charger and rechargeable battery products are not qualified. A qualified charger should have an intelligent multistage charging mode with undervoltage and overcurrent protection circuits and matching with the battery of the electric vehicle. Not qualified charger, rechargeable battery in full, because they do not have the intelligent charging function, can not enter the floating stage, the continuing high current charging of rechargeable batteries, rechargeable batteries lead to high temperature, easy to cause a fire or explosion of battery heating line. As an auto parts store in Yixing at the end of 2012 of a car at the fire, after inspection of the scene, is parked in the door of the car battery battery failure caused by fire, it is understood that the car battery is not in a state of charge in the fire, in front of the fire to the private car owners had to repair shop to replace unlicensed free a group of battery manufacturers.
- Q:Is the electric bicycle battery charged well or is it not necessary to recharge it?
- Outside, lead-acid batteries are afraid of deep discharge, that is, "loss of electricity."". So it's not right to recharge the batteries again.The correct charge method is to charge the battery when the battery is higher than 70% and less than 90%. It is difficult for ordinary people to grasp, recommendation 1. add a small battery coppersmith activator, it protects the battery plate. Overcharge and lack of charge do no harm to the battery. 2, you can estimate the mileage of a car. Suppose your car is full of electricity, you can run 50 kilometers, has run to 25 kilometers, it will recharge. In general, the charger green light to float 2 hours. If you run more than 40 kilometers a day, you have to use it.Lead-acid batteries can not use empty charge, otherwise the battery capacity will decline, if not used for a long time, 20 days or so should be sufficient once, not low voltage storage.
- Q:New electric cars to maintain, such as the speed of cycling. Charge。 The new chain needs no oil.
- Do not change the charger arbitrarily, do not remove the controller's speed limit.Each manufacturer's charger generally has personalized needs, when not sure, do not change the charger at will. If continued long trip mileage requirements, we must charge to different places and with a number of chargers, the day complement chargers to add a separate charger, and the original use of the charger at night. Removing the speed limit of the controller, although it can increase the speed of some cars, will not only reduce the safety of the vehicle, but also reduce the service life of the battery.
- Q:The origin of electric cars?
- Electric cars, in short, are powered by electricity and powered by electricity. The first electric car was made in 1834. It was driven by a DC motor. Today, electric cars have undergone tremendous changes, and there are many kinds of electric cars
- 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.
- (1) P= dreamsWTHence the motor power consumption of W=Pt=5.5kW * 1h=5.5kW H?(2) P=UI dreamsThe normal work of the motor current frequency is I=PU=5500W220V=25A,The heat generated by the coil is Q=I2Rt= (25A) 2 * 0.4 * 3600s=9 * 105J.
- Q:Which kind of electric car is good???15 girls buy electricity, which kind of good?
- At present, the electric bicycle has a maximum mileage of 30 kilometers is generally ~50 km, so the purchase of electric bicycles must be clear: that is to work as a means of transport, do not require too high.
- Q:How much is the battery charge for an electric bicycle?
- The key is to look at the size and capacity of the battery, the general 48V20Ah battery charge up to 1.5 degrees or so.
- Q:How can electric bikes be best charged?
- Don't think of the electricity used up, little time to charge this is wrong ~ ~ ~ you should pay attention to easily damage the power indicator on the battery, while the remaining 1/3 of the electricity in the electricity meter display when charging.
