The cell test lab of Contemporary Amperex Technology Co. Ltd. (CATL) was granted the lithium-ion battery cell testing qualification certificate by Volkswagen Group (Volkswagen) at CATL’s headquarters in Ningde.

It is the first test lab as cell manufacturer in the world to receive this certificate, showing that CATL’s outstanding testing capability has been recognized by the global leading automotive manufacturer, and also strengthening the cooperation between CATL and Volkswagen Group Components. 

Volkswagen has set up strict testing standards for the EV battery to pursue outstanding product quality and safety management. The standard covers scenarios of a battery’s overall lifetime operation and various applications, and features higher requirements in terms of reliability, testing cycles, testing environments and the number of test samples in comparison with global industry standards.

Supported by its profound experience in the lithium-ion battery industry, the CATL cell test lab has received Volkswagen’s recognition due to its superiorities in lab scale, testing capability and engineering capability. With huge investments totaling RMB 2 billion (over USD 314 million), a property of 60,000 square meters, and a team of more than 500 talents, the CATL test and validation center (to which the cell test lab belongs to) has developed a comprehensive testing ability and is able to carry out over 300 tests in materials, cells, modules, battery management system and packs regarding various aspects, including mechanisms, electrical performance, safety and reliability, etc.

CATL test and validation center has also developed the vehicle-level indoor fire test ability, which makes it as the first test center in lithium-ion battery industry domestically. 

Beyond battery testing, CATL and Volkswagen have developed a close partnership with an eye to future cooperation. Volkswagen’s Group and its joint venture EV fleets of MEB and MQB platforms equipped among others with CATL batteries, and their low-voltage system with CATL 12V and 48V batteries have been mass produced.
