To ensure the quality, safety, and performance of lithium-ion batteries, a series of rigorous tests are conducted. These tests cover various aspects, including physical properties, electrical performance, safety, and environmental adaptability.
- Dimension and Weight: Verifying the battery's size and weight to meet design specifications.
- Appearance Inspection: Checking for any defects or damage to the battery case, terminals, and labels.
- Case Strength: Testing the durability and strength of the battery case under mechanical stress.
- Capacity Test: Measuring the battery's ability to store and deliver energy.
- Internal Resistance Test: Assessing the battery's internal resistance, which affects its performance and efficiency.
- Voltage Test: Measuring the battery's open-circuit voltage and working voltage under different conditions.
- Rate Performance Test: Evaluating the battery's performance at various charge and discharge rates.
- Self-Discharge Test: Measuring the battery's self-discharge rate, which indicates how quickly it loses charge when idle.
- Discharge Characteristics Test: Analyzing the battery's discharge curve, efficiency, and other relevant parameters.
- Overcharge Test: Simulating overcharging conditions to assess the battery's safety mechanisms and prevent thermal runaway.
- Over-Discharge Test: Evaluating the battery's behavior under deep discharge conditions to prevent irreversible damage.
- Short-Circuit Test: Testing the battery's response to short-circuit conditions, including temperature rise and potential for fire or explosion.
- Nail Penetration Test: Simulating accidental puncture to assess the battery's safety.
- Crush Test: Testing the battery's response to mechanical stress, such as crushing or impact.
- Thermal Abuse Test: Exposing the battery to extreme temperatures to evaluate its thermal stability and safety.
- Temperature Cycling: Exposing the battery to repeated temperature cycles to assess its performance and durability under various conditions.
- Humidity Test: Evaluating the battery's performance in high-humidity environments.
- Vibration Test: Simulating vibration during transportation and usage to assess the battery's structural integrity.
- Altitude Test: Testing the battery's performance at high altitudes and low-pressure conditions.
- Electromagnetic Compatibility (EMC) Test: Ensuring the battery's compatibility with electronic devices and systems.
- Environmental Impact Test: Assessing the battery's environmental impact, including material composition and recyclability.
- Cycle Life Test: Evaluating the battery's long-term performance and capacity retention over numerous charge-discharge cycles.
