3results about How to "Extend power supply time" patented technology

This invention relates to an emergency power supply distribution and energy storage wall system, comprising an integrated wall-type shell, a dual-busbar power distribution architecture, a multi-mode seamless switching module, a load identification module, and an embedded energy management system. The dual-busbar power distribution architecture, the multi-mode seamless switching module, and the load identification module are housed within a distribution box, which is also housed within the integrated wall-type shell. The multi-mode seamless switching module enables uninterrupted voltage waveform switching of the load from the constant power bus to the emergency bus. The load identification module obtains the real-time current waveform of the load through high-frequency sampling and compares it with a built-in feature library to identify the load type. The embedded energy management system receives grid status, battery state of charge, load identification information, and user-preset strategies to execute tiered load control strategies. Compared with existing technologies, this invention offers advantages such as extending the power supply time of critical loads, ensuring stable load operation, and improving system readiness.

The application relates to the technical field of energy storage, and provides a battery cell module and a battery pack. The battery cell module comprises a plurality of battery cells and a special-shaped bus assembly. The plurality of battery cells are arranged in at least two rows and an odd number of columns; two electrodes on each battery cell are arranged at intervals along the column arrangement direction; the plurality of battery cells in the odd number of columns comprise battery cells in a separate column and battery cells in the remaining columns; along the row arrangement direction, the battery cells in the separate column are located at the end of the battery cells in the remaining columns; among the battery cells in the remaining columns, two adjacent battery cells in each row are connected in parallel to form a battery cell group, so that each row comprises a plurality of battery cell groups arranged in layers; and the plurality of battery cell groups in each row are connected in series. At least two battery cells in the separate column are connected in parallel through the special-shaped bus assembly. In this way, the capacity of the battery cell module can be increased without changing the output voltage. When the number of battery cell columns of the battery cell module is odd, at least two battery cells in the separate column can also be connected in parallel, so that the arrangement of the battery cells in the battery cell module is not limited by the number of battery cell columns.
