An Anhui subsidiary of NIO just released a patent regarding a cylindrical battery on Tuesday. The patent is expected to address the problem of low utilization rates at the effective height of the battery cells, since most existing cylindrical batteries have polar ears at both ends.
This patent cylindrical battery consists of a shell, positive pole and core winding assembly which is mounted on the shell with the positive ear and negative ear arranged on the same side, thereby increasing the space utilization rate. This reduces manufacturing difficulties and increases production efficiency. The positive and negative ears are arranged in a multi-ring distribution to optimize the distribution of the polar ears and reduce the internal resistance of the battery cells.
In early June, NIO disclosed its financial reports for the first quarter of this year. In the report, NIO will increase its investment in battery-related fields. NIO has a battery related team of over 400 employees. The team is involved in battery materials R&D, battery design, battery management system and manufacturing processes.
In the production of its electric vehicles, NIO has adopted a “homemade + outsourcing” manufacturing strategy, which can effectively increase future profits.
Previously, NIO said it would launch a new 800V high-voltage platform battery pack in 2024. The 800V battery promises a huge increase in charging power, as it can greatly shorten battery charging time.
NIO previously officially launched the ES7 which is the company’s fifth production model. The NIO ES7 is the first SUV built using the NT 2.0 platform. NIO ES7 are equipped with dual motors, including a front permanent magnet synchronous motor with a peak power of 180 kW and a rear asynchronous motor with a peak power of 300 kW.
