AI Technical Summary
In existing energy storage devices, it is difficult to fit battery modules of different models into the original chamber after replacement, and the heat of the battery modules is difficult to dissipate effectively during charging and discharging.
An adjustable bracket spacing grid energy storage device was designed. The bracket movement is achieved through a threaded sleeve and synchronous wheel transmission system to adapt to the installation of different types of battery modules, and the battery modules are cooled through a water circulation mechanism.
It enables flexible installation and stable fixation of different types of battery modules, and effectively dissipates the heat of the battery modules, improving the practicality of the device and the service life of the batteries.
