Model 17000 Series: Total Solution for Battery Formation

Chroma's total solution for battery cell production line is a total planning service for battery cell production line, from activation to graded pairing based on the process to make the most appropriate equipment or systematic planning, including instrumentation construction, logistics planning, production management system, etc., to provide a variety of customized features, tailor-made for high-efficiency production line.

The overall solution for battery formation is divided into fully-automatic and semi-automatic production lines according to the capacity and production mode, with tray-based production, where the battery cells are placed on trays and transported to various process stations for testing, and the main process stations are formation charging and discharging systems, barcode linking equipment, OCV/ACR/DCIR measurement equipment, heavy-duty picking machines, grading equipment, and static warehousing systems. Semi-automatic production line is for personnel to perform feeding and discharging operations between sites, and each site automatically performs testing and data collection, the production process is consistent, stable, and reliable, and the process is basically operated by personnel between sites, and supplemented by a process control system to avoid personnel errors.

Fully-automated production line is an integration of instrumentation, automated machinery and logistics, manufacturing information management software, all the process sites are connected into a large system, through technological management, personnel can achieve unmanned production on the scene as long as the screen operation and settings, suitable for large quantities of high consistency requirements of the production, with the advantages of saving manpower, improve efficiency and stability of the production capacity.

Chroma battery formation solutions focus on production reliability and safety, batteries in the mass manufacturing process equipment utilization rate is high, in the process of non-stop turnover is also testing the stability and durability of the equipment, Chroma has many years of experience in power electronics and measurement instruments product durability and stability to withstand the test.

Chroma has a state-of-the-art laboratory for external operations, instrument calibration and standardized traceability implemented in the product, the quality of the equipment is particularly demanding, the company has been certified by the ISO, from product design, manufacturing to shipment of quality management, product marketing around the world; in addition, the company along with the development of the industry continues to innovate technology to meet a variety of front-end applications and manufacturing needs, such as high durability and reliable contact probe development, to improve production stability of battery reservoir design, both heat dissipation and strength of carrier tray design. For example, the development of highly durable and reliable contact probes, the design of battery storage to improve production stability, and the design of carrier trays with both heat dissipation and strength, etc. We solve the user's production problems through technological power, and the selection of materials and design validation are all carried out through scientific methods, so that the performance of the products can be guaranteed.

Chroma has sales and service offices in many regions of the world, technical support for product maintenance and troubleshooting, product after-sales guarantee, Chroma equipment in the appropriate maintenance and replacement of consumables can be used for a long time.

The charging and discharging system is specially designed for the formation/discharge of lithium-ion batteries. It is manufactured in tray type and is divided into pure charging system and charging/discharging system according to the process. The system is operated by PC control, the main body consists of instrument cabinet and battery storage cabinet, the circuit equipment in the instrument cabinet, the equipment has the characteristics of high precision, high reliability and energy saving, the cabinet has a heat flow design to avoid heat accumulation to protect the stability; the battery storage cabinet consists of press-fit mechanism and electrode fixture, the battery electrode is automatically contacted to test the electrodes of the batteries after being put into the carrier tray, the professional design of the storage position can effectively improve the stability of the production, and the battery storage cabinet is divided into environmental temperature control and process characteristics. According to the temperature control method and process characteristics are divided into environmental temperature-controlled open frame type and temperature-controlled cabinet type, each storage space operates independently, and there is a fireproof design between the storage spaces to avoid abnormal delayed burning.
