Embodiment Construction

[0112] Since currently available assembled batteries require tight matching between cells, rely on the reliability of individual cells, and are difficult to transport, smart battery systems that do not require strict matching, remain effective when cells fail, and are easy to transport can undoubtedly is desirable and provides the basis for providing smart batteries for mobile platforms such as unmanned aerial vehicles ("UAVs"). according to figure 1 One embodiment of the smart battery 100 shown in , can achieve such a result.

[0113] figure 1 The smart battery 100 ( image 3 Shown in ), the battery management system (BMS) 110 includes one or more processors 181 that can work individually or collectively to manage the smart battery 100 . exist figure 1 In, the processor 181 can learn from the battery pack 120 ( image 3 shown in ) to obtain at least one cell property 191 of the group, which will refer to image 3 described in more detail. In some embodiments, the perfo...

Abstract

The present invention provides an intelligent battery system (100) and a method of manufacturing and using the same. The smart battery system (100) may have a battery pack (120) and a battery management system (BMS) (110), the BMS (110) being used to provide secondary protection for the battery pack (120). The cell pack (120) may include cells having operating parameters such as capacity, voltage, current, charge / discharge rate, and / or cycle life, which are consistent or different among the cells of. In one embodiment, the BMS (110) may include a fuel gauge (114), a microcontroller (116), and a MOS switch circuit (118) for use based on the chemical properties of the cells (120) and the operating parameters of the cells (120) to manage the battery pack and provide the secondary protection. The smart battery system (100) may advantageously include replaceable cells (120), any of the cells (120) may be disassembled and assembled for storage and / or transport without affecting the The capacity and performance of the smart battery.

The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyrights. technical field [0003] The disclosed embodiments relate generally to batteries, and more particularly to smart battery systems and methods with secondary protection, but not exclusively. Background technique [0004] An assembled battery basically consists of multiple battery cells and battery integration boards. Currently available assembled batteries require strict matching between cells and integrated boards according to application requirements, such as matching voltage, current and charge rate, to form an indivisible integrated battery. [0005] Since the battery integrated board and the batt...
