It is mainly used for the safety test of lithium battery protection board, and is compatible with various common protection board types, such as positive pole with the same port (split port), negative pole with the same port (split port), positive charge and negative electrode discharge and so on.Lithium battery protection board tester is beneficial to improve production efficiency and control quality.

Mainly have the following functions

1. Accurate test: It can accurately detect the exact value of various functional parameters of the power battery protection board (error is 1mv), which is convenient for sample debugging and development.
2. Quick test: According to the design parameters of the protection board, set the test parameters to perform a quick test, which is suitable for the protection board test of various hardware solutions and some software solutions.
3. Laboratory mode: Set the single string voltage independently, select the charging or discharging mode independently, and judge whether the MOS tube is turned off or turned on.

Test items

1. internal resistance test,
2. Overcharge and over discharge test,
3. Overcharge recovery Over discharge recovery test
4. Over current test (charge over current and discharge over current)

5.Short circuit protection test (short circuit protection test microsecond level).

6.Single-section self-consumption test (true and accurate self-consumption of each section).
Balance current and balance voltage (can accurately capture balance current and balance turn-on voltage).

Types of protection boards that support the test: lithium iron phosphate, lithium cobalt oxide, lithium manganate, lithium titanate, etc.

Technical parameters
3.1 High current module: The current level is 120A, and the current accuracy is 0.1A.
3.2 Voltage module: The voltage range is 0.5-5V, the programmable output is 0.5-5V, and the voltage accuracy is 1mV.

3.3 Short-circuit module: super capacitor, fully simulate the voltage of pack battery, short-circuit the protection board in an instant, and accurately capture the short-circuit time and current. Infrared scanning (barcode scanning) Scan the ID number of each protection board (reserved optional)
