Lithium Battery Tester
A Lithium Battery Tester is a device used to test the performance and reliability of a lithium battery pack.
Lithium batteries are commonly used in various applications, such as electric vehicles and renewable energy storage systems, etc. where the performance and reliability of each cell within the battery pack are critical for optimal performance and longevity of the battery pack.
During the tests, the lithium battery tester measures the electrical properties of each cell, such as its capacity, individual cell voltages, and cycle life, and records the test results. The test results are then analyzed to determine the performance and reliability of each cell within the battery pack.
The specifications of a lithium battery tester may vary depending on the specific model and manufacturer. However, here are some common specifications that are typically found in a lithium battery tester:
- Test parameters: The test parameters determine the conditions under which the battery will be tested. The parameters may include charge and discharge current, charge and discharge voltage, cycling time, number of cycles, etc.
- Test modes: The tester may offer various test modes, such as various currents, and voltage, depending on the specific testing requirements.
- Test results: The tester should provide accurate and reliable test results, such as the battery capacity, and efficiency, after each cycle.
- User interface: The tester should have an intuitive and user-friendly interface that allows the user to configure the test parameters and view the test results easily.
- Safety features: The tester should include various safety features to prevent overcharging, over-discharging, and overheating of the battery, which can cause damage or even lead to a fire.
- Compatibility: The tester should be compatible with various types of lithium batteries, such as lithium-ion, lithium-polymer, and lithium-iron-phosphate.
- Capacity: The tester should be able to test batteries with different capacities, ranging from small cells to large battery packs used in electric vehicles or renewable energy storage systems.
- Data logging: The tester should have the capability to log the test results, allowing the user to track the battery’s performance over time and compare the results with previous tests.

Suvastika’s Lithium Battery Test Solution consists of two parts, the Battery Tester itself and the Windows PC Software.
The lithium Battery Tester is connected to the main Power by the power cord from the back side of the panel. An ON/OFF switch is also provided.
On the front side you will see a DB25 connector to connect to the battery, this is used for tapping the cell voltages and temperature sensor located inside the battery
Battery Terminal is provided to connect the Battery Power terminals
Two USB B-type connectors are provided to connect the tester to the PC
Inbuilt FAN is provided to ensure the optimal thermal performance of the Lithium Battery tester
Windows PC Software
There are various tabs in the Windows PC Software, the first one is the dashboard where you can see all the cell voltages in a bar graph representation
Right-hand side panel gives various information about Battery Bank at the cell level what is the minimum voltage of a cell in the bank, the maximum voltage of the cell and average cell voltage, and the Imbalance cell voltage across all the cells in the battery bank.
Other details you will see are Battery Bank voltage, how is the current drawn from the battery in discharge mode, or the current going inside in the charging mode. Battery Power consumed or discharged and the Cumulative Energy in Watt Hr.
Provision is given to mention Battery ID so that test data can be stored in the database with the battery ID.
The status section shows all the alerts or warning messages like if the imbalance voltage goes above the set limit if any communication port of the lithium battery tester is not working, etc.
Debug table gives the ability to control and test all the instrumentation modules used by the Lithium battery tester like the Voltage measurement module, Energy Measurement module, charger, discharger, etc.
As mentioned, various parameters can be analyzed with trend graphs like battery voltage, battery current, energy consumed or discharged, imbalance, and individual cell voltages.
There are various settings available in the software to configure the Battery tester for a particular battery type capacity and test method. You can select if you want to test only charging or discharge or do charge-discharge.
You can set the ideal battery capacity so that software will automatically calculate efficiency/actual battery capacity Vs ideal battery capacity automatically after the test cycle is completed.
Once the tester is configured and started the autocycle tab gives you details like which mode it is working, when did it start and end, how much duration each mode took, how much energy was used in charging or discharging, Capacity percentage Vs. Ideal capacity, imbalance voltage before and after the relaxation time.
Suvastika’s team is constantly working on upgrading the features of the Lithium battery tester and its associated Windows PC Software.
