The development history of battery testing technology
Battery testing technology has gone through three major development stages: manual testing, automated testing, and intelligent testing. Each stage represents a significant leap in technology and methodology.
The technological evolution from manual to intelligent
Early battery testing mainly relied on manual operation, and technicians needed to manually record and analyze data. The characteristics of this stage are:
The testing process is highly dependent on manual operation and monitoring
The efficiency of data collection and analysis is low
The test results are susceptible to human factors
It is difficult to conduct long-term or large-scale tests
With the development of computer technology, battery testing entered the automation stage (from the 1990s to the 2010s). The main characteristics of this period include:
Introduce a computer control system to achieve the automation of the testing process
Develop dedicated battery testing equipment and software
Establish standardized testing methods and procedures
The accuracy and repeatability of the test have been improved
The progress at this stage has significantly enhanced the efficiency of battery testing, providing strong support for the rapid development of battery technology. The automated test system is capable of performing complex charge and discharge cycle tests and automatically recording and analyzing data [8].
At present, battery testing technology has entered the intelligent stage (from the 2020s to the present), and its main features are:
Apply artificial intelligence and big data technologies to predict battery performance and assess battery life
Develop non-destructive testing technology and micro-nano testing technology to improve testing accuracy

• Emphasize full life cycle testing [8]
At this stage, machine learning algorithms are widely applied in the prediction of battery cycle life. Studies show that traditional machine learning algorithms perform exceptionally well when dealing with limited data. For instance, random forest regressors can achieve an average absolute percentage error of at least 9.8% [4].
Comparison of efficiency, accuracy and cost in the three stages
Battery testing techniques at different stages have significant differences in terms of efficiency, accuracy and cost:

In traditional battery testing systems, the discharge energy is usually dissipated as heat, and the system efficiency is 0%. By using a bidirectional AC-DC converter, the dissipated energy can be returned to the system, achieving the recycling of battery test charging energy and significantly improving the system efficiency [24].

Battery testing standards are an important guarantee for ensuring battery performance, safety and reliability. With the rapid development of the global electric vehicle and energy storage markets, the battery testing standard systems at home and abroad are also constantly improving. This article will analyze the differences between domestic and foreign battery testing technology standard systems.
International Battery testing standard system
International battery testing standards are mainly formulated by the International Electrotechnical Commission (IEC), the International Organization for Standardization (ISO), Underwriters Laboratories (UL), the Society of Automotive Engineers (SAE), and relevant institutions in the European Union [13].
The standards for power lithium-ion batteries issued by IEC mainly include IEC62660-1:2010 "Lithium-ion Power Battery cells for Electric Road vehicles - Part 1: Performance testing" and IEC62660-2:2010 "Lithium-ion Power Battery cells for Electric Road Vehicles - Part 2: Reliability and abuse testing". These standards mainly target the performance and safety tests of individual battery cells [13].
The standards formulated by ISO include the ISO12405 series, which is divided into three parts: ISO12405-1 for high-power batteries, ISO12405-2 for high-energy batteries, and ISO12405-3 for safety performance requirements. The aim is to provide vehicle manufacturers with optional test items and methods [13].
The UL2580 standard of the United States mainly assesses the reliability of battery abuse and the ability to protect personnel when abuse causes harm. The SAE standard system is more complete, including SAEJ2464 for battery abuse testing, SAEJ2929 for battery system safety standards, and SAEJ2380 for battery vibration testing, etc. [13]
Chinese battery testing standard system
The battery testing standard system in China started relatively late but has developed rapidly. In 2001, the Automotive Standardization Committee issued China's first guiding technical document for the testing of lithium-ion batteries in electric vehicles, GB/Z18333.1:2011 "Lithium-ion Batteries for Electric Road Vehicles" [13].
In 2006, the Ministry of Industry and Information Technology issued QC/T743 "Lithium-ion Power Batteries for Electric Vehicles", which was revised in 2012. These early standards were mainly targeted at the monomer and module levels and had a relatively narrow application scope [13].
In 2015, the Standardization Administration of the People's Republic of China promulgated a series of standards. Including GB/T31484-2015 "Cycle Life Requirements and Test Methods for Power Batteries for Electric Vehicles", GB/T31485-2015 "Safety Requirements and Test Methods for Power Batteries for Electric Vehicles", GB/T31486-2015 "Electrical Performance Requirements and Test Methods for Power Batteries for Electric Vehicles", and GB/T31 467 series standards [13].
The main differences between domestic and foreign standard systems
1. Completeness of the standard system: The international standard system is more complete, covering all aspects of batteries, while the Chinese standard system, although developing rapidly, is still being continuously improved [14].
2. Focus of test methods: International standards place more emphasis on the safety and reliability testing of batteries, such as UL and SAE standards; The Chinese standard, on the other hand, pays more attention to the performance and cycle life tests of batteries [13].
3. Standard update frequency: International standards are updated frequently to adapt to the rapidly developing battery technology. The update of Chinese standards is relatively slow, but the update speed has accelerated in recent years [14].
4. Strictness of test conditions: In some test items, the test conditions of Chinese standards may be more stringent to adapt to the special climate and road conditions in China [13].
5. Degree of internationalization of standards: China is actively promoting the internationalization of battery testing standards, facilitating the alignment of domestic standards with international ones, and enhancing the international competitiveness of Chinese battery products [14].
With the continuous development of battery technology and the expansion of application scenarios, the battery testing standard system will also be constantly improved. The differences between domestic and foreign standards will gradually narrow, jointly promoting the healthy development of the global battery industry.
