Above the laptop battery of various types of tests, can be respectively composed of the following all kinds of test unit project to form.

Individual cell performance test

Charge and charge test

Aging test

Laptop test

The main test items and the introduction is as follows:

Withstand voltage test: the purpose is to verify the electric can work safely under rated working voltage, and verify the ability of tolerance due to instantaneouscaused conversion, surge and other similar phenomena over voltage.

B.charge and discharge test

The main test items and the introduction is as follows:

The charge and discharge test mainly focuses on different scenarios such as battery life test, operating condition simulation test, capacity test, consistency screening,

other battery parameters test and safety test.

Charge cycle: the purpose is to determine the battery is activated.The maximum voltage that the battery charging process can reach. After reaching this voltage,

the battery management system requires the charging process to end.The charging cutoff voltage is generally slightly lower than the maximum open circuit voltage

allowed by the battery

Discharge cycle:in order to determine the battery current and voltage variation during discharge.

C. Aging test

The main test items and the introduction is as follows:

Aging refers to the loading and running of the product under a certain temperature or load, and then testing whether the performance index of the product meets the technical requirements after a period of time or a cycle.Then the stability, safety, service life and battery performance of the battery can be determined.

D.Laptop test

The main test items and the introduction is as follows:

Every pcs battery must be passing test from laptop to ensure product quality.
