On May 6, 2025, financial news reported that Huizhou EVE Energy Co., Ltd. has been granted a patent for a new battery pack design, identified by the authorization announcement number CN222826526U, which was applied for on May 5, 2024. The patent summary reveals that this utility model introduces a battery pack consisting of:
- a battery cover;
- a battery module, which includes several stacked battery cells, with the pressure relief openings of the cells facing towards the battery cover;
- a battery frame, within which the battery module is assembled, and the battery cover is placed over the battery frame;
- a plastic bracket, which is fitted between the battery module and the battery cover. This plastic bracket features a channel that is recessed towards the direction of the battery module, containing several pressure relief holes that correspond one-to-one with the pressure relief openings of the battery cells. Additionally, the plastic bracket includes a first groove parallel to the channel for the installation of busbars;
- and finally, there is at least one layer of protective material placed between the plastic bracket and the battery cover, covering both the channel and the first groove.
This innovative design addresses the shortcomings of existing battery packs, specifically the weak compressive strength of the cover, which can lead to deformation and changes in the pressure relief space.
