NIO signed a contract with CATL to jointly develop long-life batteries

DoNews reported on March 14 that at today’s NIO long-life battery strategic communication meeting, NIO proposed a long-life battery solution. The goal is to achieve 15 years of power battery use while ensuring that the battery’s health is not low at the end of its life. At 85%.

In addition, NIO also signed a cooperation agreement with CATL on the NIO long-life battery research and development project.

Zeng Shizhe, Vice President of NIO Battery System, said that NIO’s long-life battery technology and operational goals are:

-The battery life can reach 15 years.

- No worries about mileage.

- End of battery life health is no less than 85%.

Weilai believes that the scientific path to achieve long-life batteries is the combination of battery intrinsic R&D and operational innovation, including battery chemical materials, cell structure, cloud operations, large model predictions, and health operation and maintenance. wait.

Among them, in terms of battery intrinsic research and development, NIO has built the largest battery research and development laboratory among automobile manufacturers. Currently, NIO has obtained 1,435 technology patents for batteries, 104 of which are related to long battery life.

In terms of operations to solve battery life problems, NIO has built a battery intelligent cloud operation system, including cloud BMS, cloud recycling, digital twins, cloud health, cloud configuration, cloud services and other sectors.

Li Bin also said that NIO is already exploring a multi-dimensional perception safety model based on NIO’s battery swap network in terms of battery safety. Zeng Shizhe revealed that so far, NIO has developed more than 300 safety management algorithms, as well as the industry's first self-developed car cloud combined with battery pack maintenance algorithm. It is said that NIO’s battery pack has been replaced and maintained 787,908 times.
