How to choose a lithium-ion battery electric vehicle motor

The speed of the low-speed machine is limited by the material, and a motor with a wider efficiency platform should be selected to extend the endurance and reduce the time of high-current discharge of the battery. Then we can only start by improving the efficiency to maximize the energy efficiency, and choose the appropriate one. The power can achieve the best effect. The weight of the motor is also a point to consider. To prevent energy waste or insufficient power, choosing a motor with a high efficiency platform and high energy density can greatly improve the acceleration performance of the vehicle. Or the faster the speed, if the maximum current limit value is fixed, but the motor power is not the better, it must be determined by the model, load, and speed. The acceleration performance of the former will be better when the efficiency platform is selected than the highest efficiency point. Better than the latter, high-speed machines can achieve the purpose of increasing vehicle speed through gear design or coil design. 3. Acceleration performance The acceleration performance of the whole vehicle is related to the maximum current limit of the controller. The stronger the load capacity, the application The range is relatively wide. Generally speaking, consumers want the car to run faster, but it will slow down the acceleration and increase the burden on the battery. In addition, the weight of the vehicle will also affect the acceleration performance. To achieve this, the low-speed machine can only reduce the number of coil turns to achieve the purpose of increasing the speed. 1. Rated power and efficiency platform Generally, the larger the rated power, the stronger the climbing power. 2. Maximum vehicle speed The maximum vehicle speed is determined by the maximum speed of the motor. ,.
