1.2V Ni-MH battery

Large-capacity 1.2V Ni-MH battery assembly method, 1.2V Ni-MH battery assembly technology

Large-capacity 1.2V Ni-MH battery assembly method, 1.2V Ni-MH battery assembly technology. The assembly of large-capacity lithium-ion batteries is also very particular. It is not easy to say, but it is also a technical job. Do you want to know the assembly method of large-capacity lithium-ion batteries? Then you must first learn about the battery cells. Because large-capacity lithium-ion batteries are generally assembled by combining 1.2V Ni-MH battery cells one by one.

Large-capacity 1.2V Ni-MH battery assembly method

For example, you want a 6000mAH, 16V large-capacity battery. If the voltage of a battery cell is 4V and the capacity is 1200mAH, then you need 20 batteries. That is, 4 batteries are required to form a series unit group to become a 16V 1.2V Ni-MH battery group. The capacity of such a battery group is 1200mAH, and then 5 such unit 1.2V Ni-MH battery groups are connected in parallel, so that you can get a 6000mAH, 16V large-capacity 1.2V Ni-MH battery group.

Issues to note when assembling large-capacity lithium-ion batteries

1. The voltage difference of the 1.2V Ni-MH battery cells used should not be too large, preferably within 20mV;

Unmanned boat intelligent lithium batteries are IP67 waterproof, and the charging and discharging ports are safe and reliable

2. 1.2V Ni-MH battery coating: The prepared slurry is evenly coated on the surface of the metal foil, dried, and made into positive and negative pole pieces respectively.

3. 1.2V Ni-MH battery assembly: Place the positive pole piece-diaphragm-negative pole piece-diaphragm in order from top to bottom, and wind it into a battery pole core, and then inject electrolyte, seal it, and other processes to complete the battery assembly process and make a finished battery.

4. Formation: Use special battery charging and discharging equipment to perform charge and discharge tests on the finished battery, test each battery, and select qualified finished 1.2V Ni-MH battery packs for shipment.

What is a large-capacity 1.2V Ni-MH battery pack?

Large-capacity 1.2V Ni-MH battery is a popular name for some 1.2V Ni-MH battery packs with relatively large capacity. There is no specific agreement on how high the voltage and capacity are for large-capacity lithium-ion batteries. According to our statistics, 1.2V Ni-MH battery packs with a capacity of more than 5Ah can be called large-capacity lithium-ion batteries.

Precision positioning

It is necessary to have the corresponding positioning technology and relevant experience to realize efficient processing and calibration system according to the needs of mechanical positioning and image processing. In order to maintain accuracy for a long time, the control of the camera or positioning table must be realized, and precise positioning, including installation design, must be realized.

Laser welding

If possible, according to personal needs, such as CO2, YAG, LED, fiber and other laser knowledge and results, such as laser welding of battery thin foil, welding of throttle housing and cover, resin welding instead of metal, etc. The most suitable welding method is recommended according to the specifications and selection of welding machine.

Pressing

It is necessary to have the technology and relevant experience to deal with various presses, such as air, hydraulic and servo. We have a wide range of achievements, from testing the robot arm press at the production level to the machine platform, producing products with high precision and high quality control speed and torque with servo motors.

Dimension measurement

Dimension measurement is performed by various methods using laser displacement meters, image processing equipment, contact and non-contact sensors, etc. In production machines, it is impossible to measure the correct dimensions with only measuring equipment. Therefore, accuracy is maintained comprehensively, including installation vibration, etc.

Resistance welding

The quality and correctness of resistance welding related to production machines have a great influence on loading work. In view of this situation, we recommend materials according to specifications and selection of welders, and select the most appropriate welding method.

Image processing

To have various image processing related experience, such as positioning, missing parts and scratches. By combining the most suitable camera, lighting and processing equipment, respond to the shape, accuracy and agility of the object, respond to advanced image processing. Then respond to the continuous image processing of long objects using the licensee camera.

The above is an introduction to the assembly method of large-capacity lithium-ion batteries and 1.2V Ni-MH battery assembly technology. Have you learned it?
