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

An intelligent battery system (100) and methods for making and using the same are provided. The intelligent battery system (100) can have a pack of cells (120) and a battery management system (BMS) (110) for providing secondary protection for the pack of cells (120). The pack of cells (120) can comprise cells with operating parameters, such as capacities, voltages, currents, charge / discharge ratesand / or lifecycles that are uniform, or different, among the cells. In one embodiment, the BMS (110) can comprise a gas gauge (114), a microcontroller (116) and a MOS switch circuit (118) for managingthe pack of cells and providing the secondary protection based on chemical characteristics of the cells (120) and operating parameters of the cells (120). The intelligent battery system (100) advantageously can include cells (120) that are replaceable. For purposes of storage and / or transportation, any of the cells (120) can be dissembled and assembled without affecting the capacity and performance of the intelligent battery.

Description

[0001] Copyright Notice [0002] Portions of the disclosure of this patent document contain material that is subject to copyright protection. 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...
