1.Each equipment is controlled independently. This equipment is a master-slave rechargeable battery integrated measurement and control system composed of a microcomputer and a single-chip microcomputer. It has a modular single-sided structure. The entire cabinet can automatically test 96 batteries that meet the battery voltage range, including the single lithium ion that meets the voltage range. The battery performs constant current, constant voltage charging and constant current discharge control and testing.

2.This equipment is mainly composed of a computer, a communication interface and an automatic battery testing cabinet. The battery testing cabinet is composed of a constant current and constant voltage source, a register control circuit, a sampling circuit, a single-chip computer, a control panel and a fixture connection terminal.

3.The control mode of the whole machine, in conjunction with the supplier's single-point sorting system, can carry out formation, classification and parameter testing of rechargeable lithium-ion power batteries, which is especially suitable for mass formation production and sorting of lithium-ion power batteries.

4.The equipment adopts AVR single-chip computer as the control center, cooperates with the peripheral sampling circuit, and is controlled by the upper-level computer to complete constant current and constant voltage charging, constant current discharge test and constant power discharge.

5.Each battery completely has an independent constant current and constant voltage power supply, which is self-contained and does not affect each other.

6.Adopt advanced anti-current impact technology to realize no current impact during charging in all channels, no matter whether charging jumps to discharge or discharge jumps to charging, there is no current impact. At the same time, combined with the invention patented constant current-constant voltage power supply technology, it realizes a smooth transition from constant current to constant voltage switching without impact (no current spikes, no current breakpoints), etc.

7.It adopts 24-bit high-precision AD and 24-bit DA circuit, which has higher test accuracy.

8.The round needle four-wire method is used for measurement, which eliminates wiring and contact errors to the greatest extent. Both current and voltage sampling are differentially converted by precise instrument amplifiers, which have higher test accuracy and better long-term stability.

9.Using current automatic fine-tuning technology, when the sampling current deviates from the set value, the output current is automatically fine-tuned to ensure the current setting accuracy within the full range.

10.A special automatic calibrator is optional (the buyer needs to order separately). The calibration of the equipment is automatically realized by the computer-controlled automatic calibrator to collect the data of each channel. All the data are automatically saved in the computer. The regular calibration of the equipment is very easy.

11. Distributed system design is adopted. Each constant current box forms a single-chip microcomputer subsystem and is connected to the main CPU through a communication line. The modular design is easy to maintain. It has the function of data power failure protection and keeps running with electric energy.

12. Each channel of the device has an independent overcharge and overdischarge protection function. The hardware protection response speed of overcharge and overdischarge is ≤50ms, and the software alarm response time is about 1s. There is an alarm function in unexpected situations. With battery reverse connection, hardware protection function
