Battery High and Low Temperature Test Chamber
This document outlines the environmental testing procedures for secondary batteries, focusing on lithium-ion batteries due to their advantages such as small size, high energy density, and safety features. The testing ensures that batteries perform reliably under various environmental conditions.
Lithium-ion batteries are highlighted for their small size, portability, and high energy density compared to nickel-cadmium and nickel-metal hydride batteries. They can be charged and discharged under any condition without reducing capacity, and they are environmentally friendly, lacking harmful metals like cadmium, lead, and mercury.
Environmental tests are crucial due to the widespread use of secondary batteries in devices like mobile phones and electric tools. These tests assess how chemical reactions in batteries are affected by environmental factors, especially temperature.
- Low/High Temperature Performance Test: Evaluates battery performance under temperatures ranging from -30°C to 30°C.
- Preservation Test: Assesses battery leakage and safety under long-term use at temperatures from -10°C to 70°C.
- Charge/Discharge Test: Repeatedly charges and discharges the battery to check performance under specific environmental conditions.
- Transport Test: Simulates air and road transport conditions, including vibration and impact requirements.
Tests are conducted in explosion-proof chambers to prevent hazards like heat, fire, and explosions. These chambers are designed to handle high and low temperatures and include safety features like CO2 fire extinguishers and gas detectors.
- Temperature Control: Ranges from -70°C to 180°C with specific cooling and heating rates.
- Humidity Control: Ranges from 20% RH to 98% RH with precise fluctuation and uniformity.
- Materials: Internal and external materials include stainless steel and cold-rolled steel with heat insulation.
- Size and Power: Various chamber sizes and power supply options are available to accommodate different testing needs.
The document provides comprehensive guidelines for conducting environmental tests on secondary batteries, ensuring their safety and performance in various conditions. It emphasizes the importance of using specialized chambers and adhering to international standards.
