The battery is subjected to the same test, which is equivalent to a regular medical examination.<\/p><p>Judgment of results: The current judgment basis is relatively broad and single, only the regulations of no leakage, no shell rupture, no fire and no explosion, lacking a quantifiable evaluation system.<\/p><p>The European Committee for Automotive Research and Technology Development (EUCAR) divides the hazard degree of batteries into 8 levels, which has certain reference significance.<\/p><p>In terms of test items: GB\/T31467. 3 lacks test content on thermal management and thermal runaway of battery packs and battery systems, and thermal safety performance is crucial to batteries.<\/p><p>How to control the thermal runaway of a single battery and make thermal runaway not sprawling, is of great significance.<\/p><p>In terms of test methods: the cycle life test of battery packs and battery systems takes too long, which affects the product development cycle and is difficult to perform well. How to develop a reasonable accelerated cycle life test is a difficulty.<\/p><h2 id=\"Summary\">Summary<\/h2><p>Battery test standards are a crucial part of ensuring the safety and reliability of battery products. It is important to understand the global landscape of these standards as well as the deficiencies in existing standards.<\/p><p>It is essential to have a quantifiable evaluation system, include test items for used batteries, and test thermal management and thermal runaway of battery packs and battery systems.<\/p><p>Battery test standards can be improved through continuous updates and development, which will enhance the safety level of power batteries.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-605b48fa elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"605b48fa\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-6babc375\" data-id=\"6babc375\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-3916caf6 elementor-author-box--link-yes elementor-author-box--avatar-yes elementor-author-box--name-yes elementor-author-box--biography-yes elementor-widget elementor-widget-author-box\" data-id=\"3916caf6\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"author-box.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-author-box\">\n\t\t\t\t\t\t\t<div  class=\"elementor-author-box__avatar\">\n\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/07\/cropped-images.webp\" alt=\"Image de Honey\" loading=\"lazy\">\n\t\t\t\t<\/div>\n\t\t\t\n\t\t\t<div class=\"elementor-author-box__text\">\n\t\t\t\t\t\t\t\t\t<div >\n\t\t\t\t\t\t<div class=\"elementor-author-box__name\">\n\t\t\t\t\t\t\tHoney\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-author-box__bio\">\n\t\t\t\t\t\tHello, I am Honey.
