BYD’s Power Batteries Achieve New National Standard Certification
Recently, BYD’s Blade Battery and Flash Charge Blade Battery have successfully passed the comprehensive testing for the latest national standard GB 38031-2025, which outlines Safety Requirements for Power Storage Batteries Used in Electric Vehicles. They have also received a professional certification from the China Automotive Technology and Research Center, meeting the new standards ahead of schedule.
The revised national standard GB 38031-2025 was released recently and will officially take effect on July 1, 2026. This new standard includes three significant upgrades:
- The battery safety requirements have become more stringent.
- Prior to the release of the latest standard, BYD placed a strong emphasis on the safety of its power batteries. In 2002, BYD adopted the lithium iron phosphate technology pathway. In 2020, BYD launched the Blade Battery, made from lithium iron phosphate, setting a new global benchmark for power battery safety and redirecting the technological pathway of power batteries.
- In 2022, BYD introduced the CTB (Cell-to-Body) technology, which features a unique sandwich structure that enhances the robustness of the battery and the torsional stiffness of the vehicle. BYD has established a “four-in-one” battery safety system, covering material safety, cell safety, pack safety, and overall vehicle safety, allowing both the Blade Battery and the Flash Charge Blade Battery to pass the latest national standard tests ahead of time, demonstrating their deep expertise in safety technology and fulfilling the latest national safety performance standards.
As early as 2020, the Blade Battery was the first to pass the puncture test. Under extreme conditions where a steel needle penetrated the cell and caused an internal short circuit, the Blade Battery exhibited no open flames, no smoke, and no explosions. In crush tests, the Blade Battery remained intact after being crushed by a fully loaded truck weighing 50 tons, showing no leakage, deformation, or smoking, and it was still operable after reinstallation.
BYD has recently released the Flash Charge Blade Battery, which is the first megawatt-level power battery in the industry to comply with the new national standard. Before the standard was published, the Flash Charge Blade Battery successfully passed a 400kN (compared to the new standard of 100kN) compression test, showing no smoke, open flames, or explosions. Additionally, it also completed a scraping test at a speed of 70 km/h (C-NCAP standard speed of 30 km/h) with an overlap of 30mm, during which the battery pack showed no cracks, leakage of electrolyte, fire, or explosions, and remained functional after being reinstalled.
The successful early compliance of both the Blade Battery and the Flash Charge Blade Battery with the new national standards not only serves as an authoritative validation of BYD’s leading technology in power batteries but also embodies BYD’s commitment to user safety. BYD is dedicated to ensuring the safety of every journey for its users.
