This document provides an overview of environmental tests for secondary batteries, focusing on lithium-ion batteries due to their advantages such as small size, high energy density, and safety features.
Lithium-ion batteries are highlighted for their small size, portability, and high energy density compared to nickel-cadmium and nickel-metal hydride batteries. They offer continuous charge capabilities and are environmentally friendly, lacking harmful elements like cadmium, lead, and mercury.
Environmental tests are crucial due to the widespread use of secondary batteries in various applications. These tests assess battery performance under different conditions, particularly temperature, which significantly affects chemical reactions within the battery.
- Low/High Temperature Performance Test: Evaluates battery performance under temperatures ranging from -30°C to 30°C.
- Preservation Test: Assesses long-term battery use and safety under temperatures from -10°C to 70°C.
- Charge/Discharge Test: Repeatedly charges and discharges the battery to evaluate performance.
- Transport Test: Simulates air and road transport conditions, including vibration and impact requirements.
Explains potential hazards like heat, fire, and explosion, emphasizing the importance of explosion-proof chambers and safety standards.
Describes the specifications of test chambers, including temperature and humidity control, materials used, and safety features like CO2 fire extinguishers and gas detectors. The chambers are designed to handle various sizes and volumes, with specific power supply requirements.
The document underscores the importance of rigorous testing to ensure battery safety and performance, adhering to international standards.

environmental test chambers Walk in Battery Explosion Proof High & Low Temperature Chamber r ^ Battery Explosion Proof High & Low Temperature Chamber L._A Why does battery heat,fire and explosion? What will happen under such phenomenon? Fire Burn somebody directly or decrease the insulation performance of components security and make the flammable liquid ignition. Secondary battery environmental test Battery type Lithium-ion batter advantages: Small size • portabilityenergy density, with same capacity, its weight is only half of the nickel cadmium battery and nickel metal hydride batteries, its volume just 20 to 50% of them. • Its action voltage is 3 times to nickel cadmium battery and nickel metal hydride battery, the machine just nedd equipped with a few batteries, small size and portablity. Continuous charge • can be charged and discharged under any condition and stock reservoir which will not reduce energy capacity to continuous charging. Safety and environmental protection • Over-charging ability and over-thermal safety. • No cadmium, lead, mercury, etc. Environmental test necessity and test methodThe necessary reason for environmental test Low/High Temp.
