China’s lithium-ion automotive battery developer Tesson New Energy has started construction of a 4GWh battery assembly facility in the eastern city of Nanjing.
Tesson, a subsidiary of Hong Kong-listed Tesson Holdings, said it plans to invest more than CNY5 billion ($790 million) in building the facility in the city’s Lishui district— that will be its headquarters for operations, production and R&D.
BBB confirmed that work started on the project on 3 March. Tesson said its aim is for the plant to become a “benchmarking base”, producing automotive battery cells and assemblies with an annual output of 400,000 battery management systems.
Tesson’s chairman Siguang Sheng said the company sees the project as a move away from battery cells manufacturing to battery assembly.
Last December, Tesson announced it had built two production lines for battery packs capable of manufacturing 1.2GWh of battery systems for automotive and energy storage applications. Another line was established for battery management systems, with an annual output of 100,000 sets.
Tesson supplies ternary lithium batteries to new energy vehicles, large-scale energy storage stations and for backup power.
