The 512-channel 5V6A cylindrical battery test equipment is a professional instrument used to perform multiple performance tests on cylindrical batteries. It has the characteristics of high precision, high stability and high automation. It can test 512 cylindrical batteries at the same time, greatly improving the test efficiency.

Main functions

Charge and discharge test: It can perform charge and discharge tests on cylindrical batteries in multiple modes such as constant current and constant voltage, and accurately measure the battery's charging capacity, discharge capacity, charge and discharge efficiency and other parameters to evaluate the battery's ability to store and release electrical energy.

Cycle life test: Through multiple charge and discharge cycles, simulate the battery in actual During the charge and discharge process in use, the performance changes of the battery under different cycle times, such as capacity attenuation and internal resistance increase, are detected to determine the cycle life of the battery.

Voltage and current measurement: The voltage and current of each channel battery can be measured in real time, and the accuracy can reach a high level.

Battery sorting: According to the set parameters, such as capacity, voltage, internal resistance, etc., the tested batteries are automatically sorted, and batteries with similar performance are grouped together to facilitate the subsequent assembly and use of the battery and improve the consistency of the battery pack.

Data recording and analysis: The equipment can record a large amount of test data, including voltage, current, time, capacity, etc., and automatically generate data curves and cycle diagrams. At the same time, data analysis can also be performed.

Key technical indicators

Number of channels: 512 channels, a large number of batteries can be tested at the same time, improving test efficiency.

Voltage range: generally DC 0~5V, meeting the test requirements of common cylindrical batteries.

Current range: charging DC 60mA~6A, discharging DC 60mA～6A, can adapt to the test of cylindrical batteries of different capacities and specifications.

Measurement accuracy: voltage accuracy and current accuracy are usually high, ensuring the accuracy of test data.

Stability: voltage stability ≤ (±1mV), current stability ≤ (±1mA), ensuring stability during the test.

Equipment components

Independent CPU board and keyboard board: realize unified control and operation of the whole cabinet, convenient for users to perform parameter setting, test control and other operations.

Constant current and constant voltage control module: provide independent constant current and constant voltage source for each channel, ensure the stability and accuracy of battery charging and discharging process, and avoid mutual interference between channels.

Bidirectional AC/DC inverter module: convert AC power into DC power, provide stable DC power supply for test equipment, and also convert DC power during battery discharge into AC power to feed back to the power grid, improving energy utilization.

Clamp: used to fix cylindrical batteries , to ensure good contact between the battery and the test circuit. Common ones include flat head fixtures, etc. The fixture spacing is generally 35MM, which can support various types of cylindrical batteries such as 18650, 21700, 32650, etc.
