About electric scooter battery life,maybe some people doesn’t know it very much,In terms of hardware and software only, the factors of the user and the environment are excluded. Four key points affecting battery life: battery capacity, motor power, motor control, and tires.
1) Motor power: The power is not as big as possible, too much waste, too small and not enough, and the power selection of the hub motor is also related to wheel diameter, speed and torque. Taking an 8-inch wheeled scooter as an example, the motor power can be in the range of 250W~350W. Each motor has an optimal power range. This is related to the output curve of the motor. The output power of the general cruising speed is just in this optimal range. Inside.
2)Battery: The battery has the greatest impact on battery life. It is highly recommended to buy a scooter that uses imported batteries. Second, the safety is guaranteed. At present, there are too many examples of spontaneous combustion explosions of scooter balance car twisting products, which are caused by the use of poor batteries.
3) Tire: The driving wheel has a large friction force, and the frictional force of the driven wheel is small, and the battery life is high, and the battery life is low.
4) Motor control mode: At present, two control modes, square wave control and positive Xuan wave control, each have advantages and disadvantages. Personally like Zhengxuan wave control, comfortable control, linear acceleration, high cost, start-up power saving, small sound. The square wave control is simple and rude, cheap and stable, accelerating straight lines, starting rushing, and cruising and saving electricity. Generally, it is recommended to use the products controlled by Zhengxuanbo. A good Zhengxuan wave control product has higher requirements on the technical capabilities of the enterprise, and more emphasis on the use experience. The overall energy utilization efficiency is 5~7% higher than the square wave control. How to distinguish between sine wave and square wave control? The sine wave control is a slight turning rotation under no load condition. At this time, the motor starts gently and smoothly, and accelerates to the highest speed continuously. Under the load condition, the starting is soft and no impact, and there is no abnormal noise, quiet and comfortable; and the square wave controller is in no In the case of load, the turning wheel will rotate a little, the motor will accelerate a little, and there will be a huge noise at the start of the load, and it will start at a higher level and should not be manipulated.
