Battery testing equipment is a series of tools and techniques used to evaluate battery performance, widely applied in the research and development, production, and quality control of batteries. These devices are capable of measuring and analyzing various parameters of batteries to ensure they meet expected performance standards. The following are the main contents that battery testing equipment can test:

1. Electrochemical performance

Capacity test: measures the amount of electricity that a battery can store and release under certain conditions, usually expressed in ampere hours (Ah) or milliampere hours (mAh).

Internal resistance test: Detecting the internal resistance of the battery, which is an important indicator for evaluating the health status of the battery.

Cycle life test: By repeatedly charging and discharging to simulate actual usage, evaluate the number of times the battery can maintain its initial capacity.

Self discharge rate: measures the natural discharge rate of a battery when not in use, reflecting the quality of battery storage performance.

Charging efficiency: Compare the ratio of input electrical energy to output electrical energy to determine the degree of battery loss during the charging process.

2. Security testing

Overcharge/Overdischarge Protection Test: Check if the battery has a safety mechanism to prevent overcharging or overdischarging.

Short circuit test: Simulate a short circuit between the positive and negative terminals of the battery to verify if there is a risk of explosion or fire.

Acupuncture test: Use a sharp object to puncture the battery and evaluate its safety under adverse conditions.

Squeezing test: Apply external pressure to the battery to ensure that it does not leak or explode when subjected to physical impact.

Thermal runaway test: Test whether the battery will cause thermal runaway phenomenon in high temperature environment, that is, the battery temperature will rise sharply, leading to combustion or explosion.

3. Environmental adaptability testing

High and low temperature testing: Evaluating the performance of batteries under unfavorable temperature conditions, including high and low temperature environments.

Humidity test: Simulate a high humidity environment and check whether the battery will have leakage or corrosion problems.

Salt spray test: Simulate marine or industrial polluted atmospheric environment to test the anti-corrosion ability of batteries.

Vibration testing: Simulate the vibration situation during transportation to ensure the stability and reliability of the battery structure.

4. Consistency testing

Batch consistency: Testing the consistency of performance between different batches of batteries of the same model to ensure stable product quality.

Single cell consistency: For multiple string battery packs, test the consistency between each individual cell to ensure balanced operation of the entire battery pack.

5. Other special tests

Fast charging compatibility test: Verify whether the battery supports fast charging technology and check its safety and durability in fast charging mode.

Wireless charging efficiency test: For batteries that support wireless charging, test their efficiency and safety during wireless charging.

Electromagnetic compatibility testing: Evaluate the performance of batteries in electromagnetic interference environments to ensure their normal operation is not affected.

Battery testing equipment helps enterprises or research institutions understand the various performance indicators of batteries by testing the above indicators, providing data support for improving design and optimizing production processes, while ensuring that products can meet market and regulatory requirements.
