Large-capacity lithium-ion battery assembly method, lithium ion battery pack technology. The assembly of large-capacity lithium-ion batteries is also very particular. Then you must learn to understand the core.

Because large-capacity lithium ion batteries are generally assembled by a lithium ion battery cell. Large-capacity lithium-ion battery packing method, for example, a large capacity battery for 6000mAh, 16V. If the voltage of a battery is 4V, the capacity is 1200mAh, then you have to 20 batches.

It is to form a series unit group to become a 16V lithium-ion battery pack. Such a battery pack is 1200mAh, and then 5 such cell lithium ion battery packs will be connected in parallel, so it can get one 6000mAh, 16V large-capacity lithium-ion battery pack. Large-capacity lithium-ion battery assembly should pay attention to problems 1, the voltage pressure different from the lithium ion battery cell used is not too large, preferably within 20 mV; 2, it is not recommended to use different lithium ion battery manufacturers with the same type of battery cell Assembly, because the manufacturer will cause the battery and battery material formulation to cause inconsistency between the battery cells, which is easy to impair the battery.

3, even if the lithium-ion battery cell using the same manufacturer is not new and old; 4, even the same manufacturer's battery, it is recommended to use the same batch of batches. The lithium ion battery is equipped with an important step 1, a lithium ion battery pulping: mixed with a special solvent and adhesive, respectively, and is mixed with a powder-shaped positive and negative electrode active material. 2, lithium-ion battery coating film: uniformly coated the formed slurry on the surface of the metal foil, dry, separately forming a positive and negative pole sheet, respectively.

3, lithium ion battery assembly: pressing the positive electrode sheet - diaphragm - negative electrode - the sequential sequence of the diaphragm is placed in the top of the top, and is wrapped around the battery pole, and then injects the process of the electrolyte, sealing, etc. Complete the assembly process of the battery, make the finished battery. 4, formulated: charge and discharge the finished battery with a dedicated battery charge and discharge equipment, detect each battery, screen the qualified finished lithium-ion battery group, waiting for the factory.

What is a large-capacity lithium-ion battery pack? Large-capacity lithium-ion battery is a relatively large common type of some lithium-ion battery pack capacity. There is no conventional specific multi-voltage large capacity or more for large-capacity lithium-ion batteries. According to our statistics, the lithium-ion battery pack above 5ah can be called a large-capacity lithium-ion battery.

Lithium-ion battery pack technology accurate positioning must have the positioning techniques and related experience of the watched, and can achieve efficient processing calibration system according to the needs of mechanical positioning and image processing. In order to maintain the accuracy for a long time, the control of the camera or positioning station also implements precise positioning, including installation design. If the laser welding can, if it can be, according to the knowledge and results of various laser lights such as CO2, YAG, LED, fibers, such as the laser welding of the battery thin foil, the soldering of the throttle and the cover, the resin welding replace metal, etc.

Suitable welding method based on specifications and selection of welding machines. Pressing the technology and related experience of various press, such as air, hydraulic and servo, etc. We have a wide range of results that are pressed from the mechanical arm of test production to the machine platform, produce high-precision and high quality control speed products and torque with servo motors.

Size measurements use laser displacement, image processing equipment, contact and non-contact sensors, etc. In the production machine, only the measurement device cannot measure the correct size. Therefore, we must maintain accuracy, including installation vibration, etc.

Resistance welding and production machine related resistance welding quality, the correctness has a great impact on load work. In view of this, we recommend the most suitable welding method based on the specifications and the selection of welding machines. Image processing should have various image processing related experience, such as positioning, missing part, and scratches, etc.

Respond to advanced image processing by combining the most suitable camera, illumination, and processing equipment, responding to the shape, accuracy and the sensitivity of the object. Then you need to respond to the continuous image processing of the long object with the licensee camera. The above is a large-capacity lithium-ion battery pack method, and the introduction of lithium-ion battery assembly technology.
