With the development of new energy, the use of lithium batteries is becoming more and more common. 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 function of lithium battery testing equipment should be 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, 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, it clarifies that in the task form, the current climbs or the form switching speed is faster. But faster response and switching time often mean cost improvement.

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

Equipment test channel parallel function, current multiple expansion, reduce operating cost.

5. Software function

such as graphical interface, free editing process, safe maintenance, support for multiple protocols, etc., usually the more generous the better.

6. Auxiliary function

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

7. Power quality on the output side

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

8. Volume

Width*Depth*Height (mm), the smaller the size is, the better, which saves floor space.

9. Music

DB, generally the smaller the better.
