512 Channel 5V Cylindrical Battery Cell Grading Machine

All Products Can Be Customized According To Customer Needs

Cylindrical Battery Cell Grading Machine：

The Battery Grading Machine is mainly used for formation and capacity grading of cylindrical lithium ion batteries.

Formation is first small current charging of a newly built lithium ion battery, aimed at forming a passivation layer on the surface of the negative electrode, that is, the solid electrolyte boundary film (SEI film).

Capacity grading means test the capacity of the cell via charge and discharge process, and grading the cells according the capacity value. This is for balance the battery pack assembling.

Battery Grading Machine is mainly composed of computer system, control software, communication interface and battery detection cabinet. The battery detection cabinet is composed of a clamp and a board body for placing the clamp, a charging constant current and voltage source, a discharging constant current source, a storage control circuit, a current sampling circuit, a voltage sampling circuit, a main control CPU, a data memory, a single-chip microcomputer program and a control panel.

Three Key Technologies:

1. Energy saving: comprehensive energy saving of more than 70%, high-power inverter technology
2. High efficiency: labor efficiency increased by 50%
3. High quality: accuracy deviation <0.5% after 500 consecutive charging and discharging, high precision and stable detection technology

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.
