512 Channel Pouch Cell Grading Machine

All Products Can Be Customized According To Customer Needs

Regenerative Pouch Cell Grading Machine

This equipment is mainly used to test voltage, capacity and other parameters during the battery formation / capacity-grading process. Based on the test results, it supports cell grading, data analysis, data upload and sharing.

Equipment Features

1. Single-point independent control: each battery has a fully independent constant-current / constant-voltage source for stable, impact-free operation. The equipment adopts 8-channel / 16-channel programmable CC-CV control modules.
2. The equipment uses STM32 microcontroller control and can work through a connected computer. It can save all test data and curves, and can also be operated through the equipment keypad to set processes, complete tests and perform sorting.
3. The status of each battery is detected and displayed in real time. If an abnormal condition occurs, the corresponding channel stops and the indicator lights up.
4. Power-loss protection allows the equipment to continue the original process after power is restored.
5. MOSFET power devices are used, making the equipment suitable for low-voltage-discharge cells such as lithium iron phosphate batteries.
6. The graphical operation interface clearly displays voltage, current, time, capacity and other data for each battery. Different colors can be configured to show working states and abnormalities.
7.  Powerful software functions and a user-friendly human-machine interface.
8. Four-wire testing interface to ensure high measurement accuracy.
9. Modular design for easier maintenance.

Advantages:

1. Product stability: Single-point independent constant current and constant voltage power supply, complete protection functions, stable operation, selected materials, fine craftsmanship, higher service life than peers, and fast inspection speed.
2. Technical excellence: The feeder-type energy-saving mode design is adopted, which has high energy-saving efficiency, flexibility, and humanized intelligent operation. The product linearity, accuracy and speed have reached high standards, and the maintenance and upgrades are good for expansion.
3. Accuracy: Each battery fixture is designed with the internationally popular four-wire principle, which avoids the superimposition of the internal resistance of the tester on the internal resistance of the battery and makes the test results more accurate.
4. Flexible: When the battery under test has low voltage, undercurrent, overvoltage, or overcurrent, the control system will close this channel and separate the battery from the device.
5. Cost-effective: rich experience, strong technology, professional management team, wide range of product use and praise from customers, the performance indicators and product quality of similar products have the most cost-effective advantages.
6. 7*24 hours after-sales service: The product is guaranteed for one year, free of charge and careful technology.

Charging mode: PWM switching power supply mode is adopted to realize constant current and constant voltage charging of the battery.

Advantages: high power conversion efficiency, generally above 85%.

Discharge mode: First, the voltage of the battery is increased by the PWM boost circuit and sent to the inverter power supply, and then gradually increased to be converted into AC power and sent to the AC grid, and finally the battery discharge power is fed back and reused.

Advantages: The discharged electric energy of the power supply is well recycled and reused, and the energy saving effect is obvious.
