Battery Charging-Discharging System

Our comprehensive testing ensures the reliability, efficiency, and performance of 48V, 24Ah LiFePO4 batteries. We use a 24A charger, resistive load, and an environment chamber to test under diverse conditions.

Environmental Chamber

Environmental chambers are specialized enclosures designed to simulate and control various environmental conditions such as temperature, humidity, pressure, and sometimes light, vibration, or gases. These chambers are used extensively in industries such as electronics, automotive, aerospace, pharmaceuticals, and materials testing for research, development, and quality control purposes.

Key Features:

  1. Temperature Control: Environmental chambers can precisely regulate temperatures ranging from extremely cold to high heat, replicating real-world conditions for testing products and materials.

  2. Humidity Control: They maintain specific humidity levels to mimic different environmental conditions, crucial for assessing product performance and durability in various climates.

  3. Pressure Control: Some chambers are equipped to control pressure levels, essential for testing products designed for high-altitude or vacuum environments.

  4. Uniformity: Chambers ensure uniform distribution of temperature and humidity throughout the testing space, providing consistent conditions for accurate results.

  5. Customizable: Chambers can be customized to accommodate specific testing requirements, including size, temperature range, humidity range, and additional features like lighting or vibration control.

  6. Data Logging: Many chambers feature data logging capabilities to record and analyze environmental conditions over time, facilitating detailed analysis and reporting.

  7. Safety Features: Environmental chambers are equipped with safety features such as alarms and emergency shut-off systems to ensure the protection of personnel and equipment during testing.
