Ningde Times has recently been granted a utility model patent for its invention titled “Battery Device, Energy Storage Device, Energy Storage System, and Charging Network“. The patent application number is CN202521533426.3, and it was officially authorized on October 10, 2025.
The patent summary reveals that the application discloses a battery device, energy storage device, energy storage system, and charging network. The battery device consists of a battery cell, a plastic component, a heat exchange component, and a casting component.
