Functional block diagram of Cylinder Cell Forming And Grading Machine
The computer first sends a setting command to the MCU. After the MCU is instructed, the battery voltage is cyclically collected by the voltage sampling control circuit, and the sampled voltage is compared with the set termination voltage to determine whether the termination voltage has been reached. At the same time, the MCU continues to compare working time or -ΔV, determine whether the termination condition is reached. If it is reached, the work of this step is ended and the work of the next step is entered. After all the steps are completed, the host computer reads the data from the microcontroller through Ethernet and then performs the capacity grading and data processing. The microcomputer can control up to 15 sets battery test cabinets. The test cabinet can be controlled online or stand-alone.
The battery testing cabinet has a modular structure and is easy to maintain. The system components have a modular structure, a menu-type operating environment, and use mouse operation to maximize user convenience. The host computer displays the current, voltage, time, capacity, and other measurement data of the specified cabinet in real-time, and the user can observe the battery charge and discharge curve and performance parameters at any time. All measurement data can be completely stored in the hard disk and can be consulted and retrieved by the user at any time. The charge and discharge curve of the battery can be enlarged, reduced, and overlapped to observe the battery's performance. Users can print statistics, reports, and curves at any time.
Note: After the battery is placed before the whole cabinet starts to work, you must press the keypad and click "9" to inspect the battery to ensure that the battery is in good contact; if the contact is poor or the battery reverse connection indicator light is on.
