With the popularity of electronic products in life, batteries have become a common electrical energy device, providing stable voltage and current for products and stable power supply. Therefore, battery detection is a key link in the design and production process of the battery to control the quality and performance of the battery, detect whether the battery is qualified, so as to optimize the design and ensure the stable operation of electronic products. So what indicators do battery tests generally need to detect?

1. Check the battery capacity

Battery capacity test is to test the size of the battery energy storage capacity, so as to evaluate the service life of the battery. The capacity of the battery is generally obtained by discharge test.

2. Voltage test

Test the stability of the battery voltage to determine whether it is within the specified range to ensure the stable power supply of the battery for the product.

3. Internal resistance test

The internal resistance test can reflect the internal condition of the battery and its conductive performance, and the greater the internal resistance, the worse the battery performance.

4. Charge and discharge test

It is to test the efficiency and stability of the battery during charging and discharging.

5. Charging speed test

Test the speed and efficiency of battery charging and evaluate product performance. For example, with the progress of science and technology, the design of mobile phone chargers is also gradually optimized, and the charging speed is gradually improved.

6. Cycle life test

It is an important indicator to measure the battery life. Multiple charge and discharge cycle tests are carried out on the battery to observe the capacity attenuation and evaluate the battery life.

7. Safety performance test

The safety performance test includes the test under the limit conditions such as short circuit, overcharge and overdischarge to ensure the safety of the battery

8. Environmental adaptability test

The battery is tested in different temperature environments to detect its performance at various ambient temperatures.

These are the main test items about battery testing, through these tests to detect and evaluate the quality and performance of the battery. In order to test batteries more efficiently, quickly and accurately, automated testing methods have become the first choice to meet user testing needs. After the test is completed, the data insight function will analyze the test indicators in a timely, accurate and multi-dimensional manner, quickly locate problems, optimize design, and improve and enhance product performance.
