HYNN, registered as 广东恒翼能科技股份有限公司, builds battery production and test lines, from cell formation and capacity-grading lines to end-of-line testers for modules and packs. Its EOL tester links each result to a barcode and talks to the BMS over CAN.

Formation lines and EOL testers are separate purchases
HYNN's company page gives the legal name 广东恒翼能科技股份有限公司 and describes intelligent battery production and test lines. Formation and grading equipment works on cells, while module and PACK EOL equipment works on assembled products with different electrical functions. The site quotes cumulative deliveries in GWh, and the figure in its text differs from the one on its counters; ask HYNN which total is current.
A notice from the Guangdong science and technology department records the change from the earlier limited-company name to the current joint-stock company. It links the two names. For current certificates and the scope of this tester, ask HYNN for up-to-date documents.
From cell formation to pack release testing
HYNN states more than 785 GWh of equipment delivered, about 100,000 square metres of plant and offices, and around 2,000 employees, over 500 of them in R&D, plus subsidiaries outside China. These totals vary between its pages. Its products run from formation and capacity-grading lines for cells to end-of-line testers for modules and packs.
Those two ends test very different things. Formation equipment qualifies each cell over several days. An end-of-line tester checks an assembled module or pack within minutes: insulation, voltage, internal resistance, BMS communication and a short charge or discharge. For an EOL tester, send the pack voltage and current, the communication protocol, the test sequence and how results should reach your MES. The formation page covers the cell side.
