The 4th EIC Three-Electric Coating Conference
Changzhou Junhe Precision Engineering Co., Ltd. Makes Its Debut
To promote the high-quality development of China’s power and energy storage battery industry and in response to the latest national requirements on battery safety standards, Changzhou Junhe Precision Engineering Co., Ltd. participated in the 4th EIC New Energy Battery “Insulation & Flame-Retardant & Thermal-Insulation” Technology Conference and the “Coating Protection” Technology Forum for Power and Electrical Equipment, held in Changzhou from September 17 to 19, 2025.
Policy Orientation · Safety Upgrade
With the release of GB 38031-2025 Safety Requirements for Power Batteries and GB 44240-2024 Safety Requirements for Energy Storage Batteries—coming into effect on July 1, 2026, and August 1, 2025, respectively—the nation has set higher safety standards: power batteries must not ignite or explode after thermal propagation; energy storage batteries must not spread thermal runaway within 24 hours, show no external flames, and maintain intact enclosures. This signals far stricter regulations and challenges for the industry in terms of safety and reliability.
