In the era of the flourishing development of the electric vehicle industry, safety has become the primary criterion for consumers when evaluating the quality of a vehicle. In particular, the safety of EV batteries and battery packs is crucial for every electric vehicle owner. During the rainy season, issues of moisture penetration and water-related safety in battery packs raise many concerns among electric vehicle owners. In this test of electric vehicle safety, VREMT has set a new benchmark for the industry with its exceptional test results and technological innovations.

Electric vehicle batteries generally have an IPX7 waterproof standard, meaning they can operate normally after being submerged in one meter of water for 30 minutes. However, VREMT does not settle for this standard and has pushed the waterproof performance to a higher level. After testing, the VREMT 800V battery pack underwent an immersion test in 10% concentrated saltwater for 48 hours, and after the test, the battery's waterproofing was good and all data were normal. This means that the VREMT 800V battery pack has reached the IPX8 waterproof standard, far exceeding the national standard, with no fear of moisture penetration or standing water on the road, thus offering electric vehicle owners a more serene driving experience.

In addition to waterproof performance, VREMT has also put significant effort into fire protection for its high-performance batteries. Its innovative "intense burning" test involves exposing the battery pack to flames over 700°C for 240 seconds, far exceeding the standards of external burning tests for electric vehicle batteries. Test results show that the cell voltage and insulation of the VREMT 800V battery pack remain normal, and after a 2-hour rest, the battery pack neither caught fire nor exploded, demonstrating exceptional high-temperature resistance and thermal runaway prevention capabilities.
VREMT's testing capability is not limited to extreme condition tests; its laboratory is also equipped to conduct comprehensive tests from the material level to the component level, up to system integration. In the field of material and electrochemical testing, VREMT conducts a comprehensive evaluation of material performance, using methods such as non-destructive analysis, elemental analysis, electrochemical analysis, and thermal analysis, to ensure that each material meets high safety standards.

In traction and energy storage battery tests, VREMT conducts comprehensive tests on the performance, safety, and functional validation of EV batteries and 800V battery packs to ensure that the battery packs operate stably under various conditions. It is particularly noteworthy that VREMT has conducted numerous tests on an 800V high-voltage system test bench, providing strong technical support for the development and application of 800V battery packs.
Moreover, VREMT has achieved significant results in motor and electronic control testing, electromagnetic compatibility (EMC) testing, charging system testing, energy storage system testing, and environmental reliability testing. Whether on high-speed single motor test benches, three-motor, four-motor, or electronic control simulation test benches, VREMT has conducted thorough tests and validations to ensure the stability and reliability of motor and electronic control systems.
In fact, the efficient thermal management battery is another highlight of VREMT. Through precise temperature control and efficient thermal dissipation design, VREMT's efficient thermal management battery can maintain stable performance under various extreme temperature conditions, effectively avoiding safety risks such as thermal runaway. This technological advancement not only enhances the safety of battery packs but also provides a broader space for the dissemination and application of electric EV battery packs vehicles.

In the future, VREMT will continue to improve its technological level and increase its research and development investments, promoting the development and application of high-performance batteries, EV batteries, 800V battery packs, and efficient thermal management batteries, to provide users worldwide with safer, more reliable, and efficient electric vehicle products. At the same time, VREMT will actively commit to fulfilling its social responsibilities and collaborate with more partners to promote the flourishing development of the electric vehicle industry.
