System Characteristics

1. With the tray as a unit, it's very convenient to load the battery at a high test speed, which is suitable for the large-scale battery production.

2.The subcomponents are designed in a large scale, which is convenient for installation, replacement and maintenance.

3.There is no direct contact between metals in a mechanical unit parts to effectively prevent dust falling during collision.

4.The two-cylinder mode is adopted to make the movement process more stable and improve the contact performance.


Functional Characteristics

1. Twice positioning method is adopted for the tray's positioning. At the first time, a positioning is made by using the guide block around the mechanical unit and the second time is the precise positioning of the dowel pin.

2. When the mechanical unit moves from bottom to top, the probe plate doesn't move and the tray acts up, which effectively prevents the contact and life of the pipeline and electric circuits of the air tube and wire stock from affecting as the probe plate moves back and forth.

3. Two smoke sensors are designed and installed on the air duct according to the direction of the air duct for every storage location; each battery cell corresponds to a temperature probe to monitor the temperature of the battery shell in real time. The dual monitoring mode of smoke sensitivity plus temperature control is effective to ensure the safety of the test.

4. The multi-needle circular probe is adopted and composed of a current needle and 2 voltage needles. The probe needle is serrated; the beryllium-copper material is gold-plated; the contact impedance is small and the temperature rise of large current is less than 10 ℃ to ensure the accuracy of current and voltage sampling accuracy.

5. The eccentricity concept is adopted for negative pressure cup design and the bottom is designed with inclined surface, which effectively prevents the residual crystallization of electrolyte. The negative pressure cup is equipped with double-layer sealing ring and filter screen device to effectively prevent the occurrence of air leakage phenomenon.

6. The negative pressure system is designed with high and low double negative pressure and all the devices are made of corrosion-resistant 316 stainless steel. The battery formed by this method has the advantages of high capacity performance of active material, small internal resistance, small probability of the shell's drumming up and long cycle life.


Test Items

1. Test of battery's negative pressure, air extraction and formation

2. Sorting test of battery capacity

High-temperature Pressure Forming Equipmen High-temperature Pressure Forming Equipmen

At present, a heating clamp is used to press the two sides of the battery during the production process of soft package batteries. The gas during the formation can be discharged into the airbag under the pressure, so that the electrolyte can be fully infiltrated and form a good SEI film during the formation of the battery cells.

MES System MES System

The MES System of HYNN can quickly and effectively realize real-time tracking and monitoring of production sites through the system's refined production scheduling, implementing production process monitoring, process route based production schedule management, and real-time information collection, analysis and feedback functions. It effectively solves the core issues in site management, and increases support for the site, thus creating a reliable manufacturing execution management system for the enterprise.

WMS System WMS System

WMS system can well record the information of product storage and delivery and allows query of the occupation status of each warehouse area and location in real time. Besides, it can review and print various warehouse-in and warehouse-out receipts to facilitate the warehouse staff to master the warehouse inventory in real time. The system also allows multi - user management, and the setting of management authority for each user group.

We have any Suggestions and requirements for us. We can inform you through the comments, and we will contact you immediately。
