Reliability Abuse Testing Machine for Electric And Hybrid Electric Vehicle Rechargeable Energy

Governments around the world continue to make regulations that require automakers to improve the average level of fuel economy, So automakers turn to gas-electric hybrid vehicles. In 2015, China’s sales of new battery electric vehicles accounted for nearly one-third of the global total, and it is expected that 5 million zero-emission vehicles will be on the road by 2020. Germany and the U.K. have also said they will stop selling gasoline and diesel cars in 2030 and 2040 respectively. With the rapid development of the electric vehicle industry, the electric drive system industry has also made great progress.

The technical level of products continues to improve, The scale of industrial development is further expanded, new materials and new processes continue to emerge, and the development trend of integration is obvious. It is also for this reason that Wewon Tech continues to increase research and development efforts for reliability abuse testing machine for electric and hybrid electric vehicle rechargeable energy.

Due to the complex driving requirements and working conditions of electric vehicles, the performance of traditional electric drive systems has been unable to meet the needs of electric vehicles. High-voltage, high-speed, and high-efficiency electric drive systems have become the main characteristics of electric drive systems for electric vehicles. In order to ensure the use performance and safety performance of the electric drive system for electric vehicles and improve the technical level of the products, China has established a relatively complete drive motor standard system, which has played an important role in promoting the technical improvement of motor products, accelerating the improvement of safety, and ensuring effective testing. to the role of norms and guidance.

Competition in the automotive industry and the pace of development of hybrid technology have prompted manufacturers to invest in battery research and development. Time-to-market is critical, and comprehensive product testing of batteries should not be overlooked, as recalling vehicles can be costly. Batteries and their sub-systems (such as connections, cooling, etc.) are prone to failures over long periods of time, which can range from battery performance degradation to complete failure.

Power batteries are the heart of electric vehicles and the key to the development of the new energy vehicle industry. In 2004, China proposed to actively carry out research and industrialization of new types of power such as electric vehicles and vehicle power batteries; In 2009, it was proposed to include the “lithium-ion battery/supercapacitor” hybrid system into the scope of subsidies for new energy vehicles; In 2012, it was proposed to formulate management methods for power battery recycling and utilization, and establish a cascade and systematic power battery recycling and utilization management system; From 2017 to 2025, the specific energy of power battery cells will reach 500 Wh/kg. According to the plan from 2021 to 2035, China will implement battery technology breakthrough actions, build a power battery recycling system, and speed up legislation on power battery recycling.

 


Power lithium-ion batteries must pass a series of safety tests before they can be used in electric vehicles. These safety tests are designed to understand and identify potential weaknesses and vulnerabilities of batteries under abnormal conditions and to determine how batteries will perform under severe and severe conditions. Compared with other types of batteries, lithium-ion batteries have the advantages of green environmental protection, high voltage, long storage and cycle life, strong charge retention ability, and no memory effect. They have been widely used in power systems, microgrids, ships, etc. , aerospace, rail transit and many other industrial fields.

Lithium-ion battery is an important energy storage element, and its performance and safety indicators are directly related to the reliability and economic benefits of the equipment. Therefore, a storage system (ress) safety and abuse testing is needed to achieve accurate testing and evaluation of lithium-ion batteries. Electric vehicles are developing rapidly and have become a must-have model for gasoline and diesel vehicle manufacturers to a certain extent.

Currently, There are many naming conventions for various vehicle technologies. The main types include Pure Electric Vehicles (BEV) and Hybrid Electric Vehicles (HEV) with Internal Combustion Engine (ICE). The main difference between traditional conveyor system testing and HEV/BEV testing is the addition of one or more electric motors to HEV/BEV, including variable frequency technology, battery cooling and transmission design. Compared to internal combustion engines, Reliability abuse testing for electric and hybrid electric vehicle rechargeable energy presents us with new challenges.
