Powertrain of New Energy Vehicles

Today, Bianshao Automobile briefly introduces friends to the powertrain of new energy vehicles, which refers to a series of parts that generate power in the vehicle and transfer it to the road. Broadly speaking, it includes the engine, transmission, driveshaft, differential, clutch and so on. However, under normal circumstances, most powertrains refer only to the engine, transmission and other components integrated into the transmission. Below, we give our friends a brief introduction to the powertrain of new energy vehicles.

Introduction of powertrain for new energy vehicles

Powertrain plays a crucial role in the improvement of electrification level, and its technology and manufacturing level affect both the performance and cost of the whole vehicle. With the decline of policy subsidies, new energy vehicle enterprises are also facing the contradiction between consumers' expectation of price and the difficulty of cost reduction. As core components, motors, batteries and electronic control systems take up most of the cost of the entire new energy vehicle. Data show that in a new energy vehicle, the cost of the motor and regulator accounts for 25%, and the cost of the power battery is as high as 45%. Therefore, in order to reduce costs, it is necessary to operate &rdquo.

Electric drive response is one of the core components of new energy vehicles, which is crucial to the performance of new energy vehicles. Tsinghua University Department of Automotive on behalf of Grant Gao Dawei said that the electric drive for new energy vehicles power, rationality, comfort, safety factor, reliability and durability is critical. Improve the level and quality of electric drive technology, should start from the drive capacity, drive efficiency, regulation accuracy, system stability, electromagnetic performance and working life and other six key technologies. In addition, from the point of view of the needs of industrialization, low cost, miniaturization, intelligence is the top priority.

Yu Ping, chairman of Jinjing Electric Technology Co., Ltd. said that in the past, electric drives use discrete components, but now, assembly and integration has become the industry's technology development trend. Take the integration of precision motors and gearboxes as an example. After integration, the number of bearings is reduced and traditional efficiency is increased. Compared with the traditional assembly structure, the axial dimension is reduced by 65 millimeters, and the other two directions are reduced by 10-20 millimeters, which can reduce the weight by 4 kilograms, which is conducive to reducing product costs.

In addition, high-efficiency permanent magnet motors also have the advantage of reducing power consumption, operating costs and battery costs, has basically replaced the asynchronous motor, becoming the mainstream of the market. ACAL head of industrial strategy, Joachim Fetzer (JoachimFetzer) also pointed out that you can do a good job at the same time in the production of physical products and electronic research and development, thus shortening the cost of the product, research and development costs, maintenance and warranty costs, so that the optimization of defined travel schedules can be achieved, thus ensuring that the entire travel schedule can basically achieve more than 90% efficiency.

According to Fang Cheng, deputy general manager of Changzhou Yikong Automotive Electronics Co., Ltd, there are some newly developed motor regulator platform products in the industry, integrating dual motor regulators, DC/DC power supplies, regulators, testing instruments and so on. The integrated platform meets the development trend of integration, miniaturization and intelligence, and can reduce cost, volume and weight.

Well, today Bianshao automobile introduced to friends of new energy vehicles power of the total achievement is fantastic. Regarding the powertrain of new energy vehicles, foreign countries are also promoting similar platformization projects. If you want to know more, please pay attention to this website!
