Service Background
Battery performance testing for low-altitude aircraft (such as drones, eVTOLs, etc.) is a core component in ensuring their safe, reliable, and efficient operation, verifying whether the battery can meet flight requirements. During application, aircraft require batteries to provide high-power energy in short periods (such as takeoff and climb) to ensure sufficient endurance. Furthermore, various abnormal mechanical and electrical stresses encountered during application may lead to battery fires, explosions, and leaks. As the energy source for aircraft, battery failure could result in crashes, collisions with buildings, or attacks on crowds. Due to the environmental sensitivity of battery chemical and physical properties, comprehensive testing can verify whether batteries can maintain safe, stable, and reliable performance under complex, variable, and even extreme environments. Extreme environments such as high-altitude low temperatures and ground-level high temperatures can significantly affect battery performance. By conducting performance tests on batteries under different environmental conditions, problems such as capacity decay and internal resistance surges can be detected in advance, and the battery's capacity, cycle life, and environmental tolerance can be verified. Conducting safety performance tests on low-altitude aircraft batteries throughout their entire life cycle can expose design flaws, optimize battery systems, verify and manage potential risks, ensuring safety for individual flights and guaranteeing large-scale commercial operation.
