Now the development of electric vehicles is getting faster and faster, and the research and development of electric vehicle motors has attracted everyone’s attention, but there are very few people who really understand electric vehicle motors . The editor collects a lot of information for you, and tells you about the knowledge of electric vehicle motors and the ranking list of new energy motors. Let’s explore the heart of the car with technology!
The Status of Electric Vehicle Motors
The electronic control system is the brain of the electric vehicle, directing the operation of the electronic components of the electric vehicle, and the on-board energy system is the technology in the electronic control system. It is a link connecting the battery and the battery pack with the vehicle system, including battery management. technology, on-board charging technology, DCDC technology and energy system bus technology, etc. Therefore, on-board energy system technology has increasingly become an important direction of industrial application technology research, and has increasingly become an important symbol of industrial development. At present, this technology has become an important bottleneck restricting the connection and development of the electric vehicle industry chain.
Industrial transformation of electric vehicle motor
There are signs of transformation from research and development to industrialization of electric vehicles. Automobile companies and manufacturers of power batteries, drive motors , controllers and other components have developed and grown during several years of promotion and demonstration work, and have launched a series of products that meet performance requirements. However, as a common key technology, key component technologies such as drive motors and batteries, their reliability, cost, durability and other main indicators cannot meet the needs of the development of electric vehicles, which has become the main constraint factor for the development of electric vehicles.
Difficulties in research and development of electric vehicle motors
From the perspective of the electric vehicle industry chain, the beneficiaries may mainly focus on parts and components, and companies with strong control over resources in the upstream resource end will also benefit more. The main reasons for R&D difficulties are as follows:
: The battery is a big bottleneck in current electric vehicle technology and cost.
Second: Due to the scarcity of mineral resources, upstream resource companies such as lithium and nickel will also have greater profits.
Third: OEMs are currently relatively chaotic and have no definite monopoly characteristics. They should first pay attention to manufacturers that have technology or have technically mature models that can be commercialized.
4. Electric vehicle motor requirements for drive system
Voltage, small mass, large starting torque and large speed regulation range, good starting performance and acceleration performance, high efficiency, low loss and reliability. When selecting an electric vehicle motor drive system, several key issues need to be considered: cost, reliability, efficiency, maintenance, durability, weight and size, noise, etc. When selecting a geared motor for a pure electric vehicle , it includes the selection of motor type, power, torque, and speed.
