With the continuous improvement of the battery system supply chain, the new energy vehicle market has maintained a vigorous growth trend in recent years, with production and ownership of cars steadily increasing. Correspondingly, competition among new energy companies has become increasingly fierce, striving for “new heights,” while user concerns regarding the safety of EV batteries are also rising. As one of the cores of new energy vehicles, the safety performance of EV batteries has become a key indicator for users to assess overall vehicle safety.
As the scorching summer draws to a close, typhoons and heavy rains still frequently “make appearances.” During the rainy season, the air is humid, and standing water is often present on the roads. Whether it’s vapor penetration or battery packs getting wet, these are common concerns for new energy vehicle owners. VREMT adheres to its brand’s consistent safety ethos, leveraging its industry-leading high-performance lithium battery development capabilities to create a powerful heart for new energy vehicles. Its 800V battery pack series products feature comprehensive safety assurance capabilities, addressing the pain points of new energy vehicles regarding battery safety.
VREMT’s Testing Capabilities Exceed National Standards, Allowing Safety Levels Without Limits
The safety quality of EV batteries directly impacts the overall vehicle safety performance. Therefore, the state and industry have established strict testing standards for EV batteries. To test the waterproof capability of its EV batteries, VREMT has pioneered a unique “Deep Sea Water Prison” test, where the battery packs are immersed in a 10% saltwater solution for 48 hours to test the limits of the battery system. The test results indicate that VREMT’s batteries show excellent airtightness after immersion, performing well beyond IPX7 national standards, achieving IPX8 waterproof level, thus showing resilience against humidity in the rainy season and standing water on roads, further enhancing its product capabilities.
Beyond waterproofing concerns, numerous reports of new energy vehicles “catching fire” online are also a primary safety issue for vehicle owners. VREMT strives for extreme performance not only in waterproof capabilities but also in ensuring EV batteries are “fire-resistant.” VREMT’s groundbreaking three extreme tests, including the “External Fire Burning” “Blazing Flame Test,” is one such example. In the testing process, the battery pack must endure flames exceeding 700°C for 240 seconds. Results show that VREMT’s EV battery cell voltage and insulation of the entire pack remain normal; after 2 hours, the battery did not catch fire or explode, exhibiting resilience against high temperatures and thermal runaway. As the industry’s first effective thermal management battery that can withstand a 240-second fire test, VREMT has again set a new safety benchmark.
VREMT’s Testing Capabilities Across Multiple Testing Areas, Upgrading Safety Standards
VREMT’s safety standards for its 800V battery pack series products are not limited to extreme operating condition tests. Beneath the strong safety ethos lies a robust production process and a rigorous testing protocol. Founded on the new energy vehicle’s three electric industry, VREMT has accumulated substantial technical strength over ten years of exploration. The VREMT electric laboratory spans 37,000 square meters, with approximately 300 million yuan invested in testing equipment and a team of experienced experts and industry veterans capable of testing from material-level to component-level and system-level integration. This allows for multiple EV battery safety experiments, including material and electrochemical tests, power battery and energy storage tests, motor and control tests, electromagnetic compatibility (EMC) tests, charging system tests, energy storage system tests, and environmental reliability tests, fulfilling various domestic and international testing standards and enterprise product specifications.To ensure safety and compete at the pinnacle of safety performance, VREMT’s stringent standards for high-performance lithium batteries not only provide a solid foundation for the EV battery industry of new energy vehicles but also contribute to an industry-wide reform of battery safety levels and promote high-quality development with unparalleled high-level safety assurances.
