Temperature-Controlled Battery Short Circuit Testing Machine

Temperature-Controlled Battery Short Circuit Testing Machine  I. Product Overview The temperature-controlled battery short circuit test machine is designed in accordance with various battery short circuit test standards. The short circuit device must meet the internal resistance range of ≤5mΩ to achieve the required maximum short circuit current. Additionally, the circuit design of the short circuit device is designed to withstand large current impacts. Therefore, industrial-grade DC electromagnetic contactors, all-copper terminal posts, and internal copper plates are used for current conduction. The wide and thick copper plates effectively improve heat dissipation, making the large current short circuit device safer and reducing the equipment's wear and tear, ensuring accurate test data. II.

Battery High Altitude Low Pressure Simulation Test Chamber

Battery High Altitude Low Pressure Simulation Test Chamber  I. Product Overview: This test chamber is designed according to UL, EN, IEC, and other standard testing requirements. It can rapidly achieve the low-pressure storage state of the sample and automatically control the test cycle. The pressure changes within the chamber are monitored throughout the test, and the test is automatically terminated once the set parameters are met. The chamber simulates the storage conditions for batteries and battery packs at a pressure of 11.6 kPa or lower and an ambient temperature of (20±5)℃ for 6 hours. A battery is considered qualified if there is no leakage, no gas emission, no disintegration, no rupture, and no fire, and the open-circuit voltage of each tested battery or battery pack after the test is not less than 90% of its voltage before the simulation test. II. Compliance Standards: GB/T 18287, UL 2054, UN 38.3, UL 1642, IEC 61960, IEC 62133, and other relevant testing standards.  III. Product Parameters Pressure Range 0.5 ~ 100 kPa, commonly used 11.6 kPa Pressure Fluctuation ≤ 5% Timer LED display, adjustable 0-99 hours (H/M/S seconds switchable) Vacuum Display Pointer type or digital display Safety Device Over-pressure protection, automatic alarm in case of operational error or end of test time Inner Chamber Material Stainless steel Outer Chamber Material A3 cold-rolled steel plate with baked paint Shelving Material Stainless steel Inner Chamber Dimensions 400x400x450mm (LxWxH) Outer Chamber Dimensions 550x550x1200mm (LxWxH) Weight Approx. 120kg Power Supply AC 380V, 50Hz
