WGDW-400L-40BC-5V30A96CH not only connects to BTS testing systems, efficiently processes large-scale data and complex computational tasks, meeting various high-performance computing requirements, but also provides high and low temperature experimental temperatures. Test battery performance changes at different temperatures. The explosion-proof feature creates a safe testing environment for battery cell testing,
Battery trays adopt high-temperature resistant insulation material, ensuring compatibility with a wide range of batteries. The height, orientation, and placement position can be adjusted accordingly, making it suitable for various sizes and specifications of square cells testing requirements.
The exterior wall material is made of high-quality cold-pressed steel plate, and the insulation structure consists of a 2.75"(70mm) insulation layer composed of rigid polyurethane foam and glass wool. This insulation layer effectively isolates the internal and external environments, preventing heat exchange and keeping temperature fluctuations within the range of ±0.9℉(±0.5℃).
Integrating the charging and discharging detection equipment with the high and low temperature environmental test chamber, this integrated testing system not only saves valuable laboratory space but also significantly improves the efficiency of equipment use. By connecting to the BTS battery testing system, it achieves unified control over battery testing and temperature conditions, making the operation more convenient.
By adopting a mechanical compression folding refrigeration method and equipping a fully enclosed piston refrigeration compressor, the system operates in an environmentally friendly manner with low noise. The self-developed temperature control module has undergone reliable performance testing for high and low-temperature impact, vibration, EMC, and other related reliability aspects, exhibiting a robust and sensitive temperature control capability.
Building upon the WGDW-50L-40-5V30A16CH, we have introduced a tri-combined casing unit, where each individual chamber is equipped with a temperature control system allowing for independent temperature regulation to meet various testing requirements. This multi-zone battery testing solution offers greater flexibility for battery researchers, enabling more accurate and comprehensive performance assessments of batteries under different temperature conditions.
The WGDW-50L-40-5V30A16CH focuses on user experience, featuring a touch liquid crystal display design with a friendly graphical user interface and flexible configuration options, allowing users to easily set up and manage the device. It also has an independent over-temperature protector that will shut down the system and send an alarm signal when the temperature in the working chamber exceeds the set limit.
