How To Judge The Performance Of Lithium Battery Testing Equipment

With the development of new energy, the application of lithium batteries is becoming more and more extensive. This also puts higher and higher requirements on the detection of lithium batteries. So how to judge the performance of lithium battery testing equipment?

The performance of lithium battery testing equipment is mainly judged from the following points:

1. Test accuracy

(E.g. 0.05%FS+0.05%RD, 0.1%FS+0.1%RD)

The smaller the value, the higher the test accuracy, and the smaller the error between the data test value and the true value.

2. Current response time, switching time

(Such as 100ms, 10ms, 1ms, etc.), the smaller the value, the faster the current climb or state switching speed in the working state. But faster response and switching time often mean increased costs.

3. Data collection frequency

(Such as 10HZ, 1HZ, etc.), the higher the frequency, the faster the data collection, the more accurate the voltage and current display values, and the more accurate the capacity calculation.

4. Hardware scalability

The equipment test channel parallel function, the current multiple expansion, reduce the use cost.

5. Software performance

Such as graphical interface, free editing process, security protection, support for multiple protocols, etc., usually the more abundant the better.

6. Accessibility

Such as GGS, BMS, BBS, auxiliary voltage, temperature, air pressure, flow, fire monitoring, etc., usually the more abundant the better.

7. Input power quality

High power factor and low harmonic distortion rate have little impact on the power grid.

8. Volume

Width*depth*height (mm), generally the smaller the better, saving space.

9. Noise

dB, generally the smaller the better.
