    However, in the past month, many incidents of spontaneous combustion of pure electric vehicles have also made the public question their safety.
    Not long ago, a Weimar electric car parked near Beijing’s North Fourth Ring Road suddenly exploded without charging.
    Weimar Motors responded that the preliminary investigation was due to a battery problem.
    As the "little expert" of secondary batteries, why do lithium-ion batteries frequently "explode"? How to make the battery have a higher energy density and at the same time be safer? If you want to increase the "volume" of the lithium-ion battery without increasing the "danger", the battery tester has become an indispensable treasure.

    Status Quo of China's Lithium-ion Battery Testing Instruments Market

    China’s lithium-ion battery has been developed to the present.
    Driven by energy technology reforms and emerging technologies, the production of lithium-ion batteries has increased rapidly*.
    As one of the important producers of lithium batteries, China’s production of lithium-ion batteries will exceed 12 billion in 2020.
    The rate reached 24.
    51%.
    In 2021, the national output of lithium batteries is expected to reach 13.
    4 billion, a growth rate of 26.
    74%.

     

      The lithium-ion battery industry has sprung up, which also brings new opportunities to the field of lithium-ion battery testing.
    In addition to the battery cell sorting detection system, charge and discharge detection system, protection board detection system, wiring harness detection system, BMS detection system, module EOL detection system, battery pack EOL detection system, and working condition simulation detection, the lithium battery testing equipment is necessary for the production and manufacturing process.
    System and so on.
    The research and development of new lithium battery technology is also inseparable from various analysis and testing instruments, such as thermal analyzers or X-ray diffractometers, to analyze the crystalline performance of lithium battery cathode materials; particle size analyzers and surface area instruments to analyze the particle size and pore size of lithium battery anode and cathode materials Wait.
    With the continuous improvement of the level of basic scientific research instruments for lithium-ion batteries, almost all kinds of scientific instruments have gradually appeared in the research of lithium-ion batteries, and many instruments and equipment in the lithium-ion battery industry have been developed for the research and manufacturing of lithium-ion batteries.

      Battery testing equipment is still "impact in the ointment"

      The power battery testing equipment currently on the market mainly includes: high-precision battery tester and lithium iron phosphate power battery testing equipment.
    Among them, the accuracy of the high-precision battery tester can reach 0.
    05%, and its accuracy is relatively high in the industry.
    It can be used to test the current, voltage, capacity, cycle, life, and internal resistance of the battery.
    The high-precision battery tester can be controlled by a computer.
    The test data and test time of the battery are displayed in one interface, so that the test results are clearly visible and easy to operate.
    This shows that the battery tester is more cost-effective.

     

      The lithium iron phosphate power battery testing equipment has the function of constant current discharge of the battery pack and the function of intelligent charging of the battery pack.
    The charging current is continuously adjustable from 0-100A, which can meet the charging and maintenance of the battery pack.
    In addition, the device also has online monitoring functions and fast capacity analysis functions, which can monitor and display all test data online in real time, such as current, battery pack voltage, single cell voltage, discharge time, capacity, etc.
    At the end of the check discharge test, the remaining capacity of each monomer can be quickly analyzed.
    At present, most of the lithium iron phosphate power battery testing equipment on the market can be tailored to meet the needs of users with different voltage levels, meeting different numbers of cells, and different capacities.
    It can be seen that the equipment has the capacity of iron-lithium batteries.
    A necessary inspection tool for testing, daily maintenance, type testing, and factory testing.

     

      Judging from the current situation of the lithium-ion battery testing instrument market summarized above, most of the current instruments and equipment are mainly for the production and manufacturing of lithium battery testing systems, but there are few types of analytical instruments required for research and development .
    Looking at the current domestic lithium battery companies, low-end overcapacity and insufficient capacity are the status quo of the industry, and the quality of lithium battery products is an inevitable development trend.
    The trend must maintain high R&D investment to ensure continuous material improvement and technological innovation.

      The future blueprint of battery testing equipment

      New energy vehicles have been a hot discussion vocabulary since their birth.
    On the one hand, it is the country's vigorous development, and on the other hand, it is social demand.
    As an important branch of the new energy automobile industry chain, the development of power battery testing equipment is currently experiencing explosive growth*.
    Under the dual influence of policies and the environment, competition in the entire market is quite fierce, and the rapidly developing market situation has brought opportunities and challenges to the development of the entire lithium battery testing equipment industry.

     

      According to market forecasts, my country's lithium battery demand will reach 200GWh in 2020, and the production capacity will exceed 270GWh.
    According to the current development status of the domestic lithium battery industry, the total investment corresponding to 1GWh of power lithium battery production capacity is about 600 million yuan, of which equipment investment accounts for 65%.
    The cost of formation and maintenance testing equipment accounts for 20% of the equipment.
    Therefore, the investment in formation and maintenance testing equipment corresponding to 1GWh production capacity is about 78 million yuan.
    It is estimated that in 2021, the scale of my country's formation, maintenance and testing of lithium battery equipment will be about 4.
    2 billion yuan.

     

      In the future, the quality of lithium battery products is the only way to go.
    Once the development trend of lithium batteries takes the course, the corresponding battery testing equipment will inevitably follow the same steps.
    This means that it is only a matter of time before the future lithium battery testing equipment takes the route.
    And with the further improvement of lithium battery production technology and battery performance, lithium batteries will occupy the mainstream market in fields such as energy storage batteries and power batteries.
    There are many types of lithium battery maintenance and testing equipment, and it is believed that the market share will continue to rise in the next few years.
