Since establishment, Liance has gradually formed testing technologies and equipment for dynamical system in the fields of fuel vehicles and vessels. After merging with Nantong Changce in 2014, Liance further formed powertrain testing technologies and equipment for new energy vehicles. In 2015, Liance started to research the testing technologies for aeromotors, and began to realize the revenue in the aero field in 2017. In 2019, Liance developed the manufacture technologies for high-speed hydraulic dynamometer for aeromotor testing, further expandingthe business. Successfullyreplacing theforeigntesting equipmentmanufacturers, Liance becamethe first domestic supplier for the high-speed hydraulic dynamometers used in the aeromotor test bed of many aeromotor enterprises in China.

Test service is an emerging business in recent years. When the automobile manufacturers faceheavy research and development tasks, and lack enough test equipment or related personnel, they need to purchase test services from a third party if it’s not cost-effective under the long cycle of purchasing test equipment or recruiting personnel. In 2015, Liancebegan to provide testservice for fuel vehicle engines and gradually expanded to new energy vehicles. Relying on the strong R&D and manufacturing capabilities, the investment and operation costs are controllable, ensuring high profit level of the test services. During 2018 to 2020, the gross profit margin of the test services remained above 65%.

In future, Liance will continue serving the country with industry, break through the technical barriers of foreign high-end test equipment and test system, seize the historical opportunity of homegrown substitution, and create "international first-class, domestic leading" test equipment and testservices with independent intellectual property rights to realize import substitution and contribute to the development of new energy vehicles and aviation industries.
