The battery charge and discharge tester is a very common test equipment for power lithium batteries. New batteries need to be used for matching and consistent selection; during the whole process of battery pack design, several stages of testing need to be used to achieve battery charging; research For the function of the battery pack, the battery charging and discharging tester is needed to carry out the working condition test; the old battery, the battery charging and testing the physical condition; some verification. The regular inspection should be completed according to the owner's regulations, and the battery charging is required. Generally, the battery is charged and discharged. What are the functions of the tester?

1) It has the function of constant current power supply and constant voltage battery charging, and can carry out automatic life cycle system, fully automatic test of standard working condition or set working condition by human factors; circulation system test, but embedded in the circulation system;

2) It has the function of describing the real-time current, voltage, temperature, power consumption and other relevant test data information and the specific content of common faults;

3) Different battery charging stop standards, total voltage, single voltage, battery concentration polarization, etc. can be installed;

4) Safety precautions, operation against current, overvoltage, reverse phase, undervoltage protection, undercurrent, short circuit fault, power failure maintenance, etc. common fault conditions;

5) According to the test description, make time-voltage. time-current. time-link volume. time-total charging volume. time-total charging and discharging volume. time-total volume. Kinetic energy. Time-single battery voltage. Circulating system frequency-specific link volume (circular system volume attenuation coefficient curve) and other graphs;

6) Display on the screen, the host computer software indicates, the sound and light alarm, the display screen key in. Select, the host computer software key in. Select and other human-computer interaction.

The battery charge and discharge tester can carry out various forms of charging process, constant voltage charging, constant current power supply charging, constant current and then constant voltage charging, positive direction single pulse charging, positive and negative electrode single pulse charging. Need to use, carry out the whole process of charging in different ways.
