Online Monitoring solution for Electric Vehicle Drive System

Scene Introduction

Since the State Council released the "Development Plan for Energy Conservation and New Energy Vehicle Industry (2012-2020)" in 2012, China has adhered to the strategy of pure electric drive, and the development of the new energy vehicle industry has achieved great success, becoming one of the important forces for the transformation of the world's automotive industry.


In 2020, the General Office of the State Council issued the Notice on the Development Plan for the New Energy Vehicle Industry (2021-2035) (Guobanfa [2020] No. 39), hereinafter referred to as the "Plan". The Plan points out that the development of new energy vehicles is a necessary path for China to move from a major automobile country to a strong automobile country, and is a strategic measure to address climate change and promote green development


In the past two years, the development of electric vehicles in China has accelerated, and the production and sales of new energy vehicles have increased significantly. In 2021, the domestic production and sales of new energy vehicles reached 358.4 × 104 and 356.0 × 104 respectively, with a year-on-year growth rate of 160%. The sales penetration rate was 13.6%, exceeding the key point of 10%. Domestic new energy vehicles entered the growth stage from the import period. In 2022, the domestic production and sales of new energy vehicles will further soar, reaching 705.8 × 104 and 688.7 × 104 units, with year-on-year growth rates of 96.9% and 93.5% respectively, ranking first in the world for 8 consecutive years. The annual sales penetration rate is as high as 25.6%


Industry demand

With the rapid development of the electric vehicle market, the requirements for the performance and reliability of electric drive systems have become more stringent.
