B) TECHNICAL FIELD
[0001] The present invention is generally related to charging systems. The present invention is particularly related to a system and method for autonomously charging the charge storage device such as rechargeable, multi-chemistry battery packs (Li-ion, Li-Po, Ultracapacitor/ Supercapacitor, etc.,) including multiple cell configurations. The present invention is more particularly related to a system and method for autonomously charging the charge storage device used in many mobile units like Unmanned Aerial Vehicles (UAVs), Unmanned Ground Vehicles (UGVs), Electric Vehicles (EVs), and any other charge storage devices thereof.

C) BACKGROUND OF THE INVENTION
[0002] The traditional charging systems require the charge storage device to be connected to the charger with a constraint on cable length. The traditional charging system also requires more than two contacts to be made for cell balancing and data communication. Hence, the charge storage devices are required to be removed from their consumer and connected to the charger for charging. This is a manual process and pre-assumed that the manual operators have the technical know-how about the cell chemistry to set the right charging profiles.
[0003] For instance, consider the current UAVs and some UGVs. In order to charge the battery packs, the operator has to remove the battery pack manually, connect the power and cell contacts to the charger, select the required charging profile and start charging. In addition to contact-based charging, contactless charging methods are also known that are based upon the principle of electrical induction. The current problems associated with the contactless charging method are strict alignment requirements between the primary and secondary inductive coil, limited power transfer rate and efficiency, increase in the complexity and payload of the charging circuit on the consumer.
[0004] Furthermore, some of the patent and patent applications related to charging systems are given below. US20160336772A1 discloses a method and an apparatus for charging the charge storage devices on mobile consumers that have contact-based charging as the preferred embodiments.
[0005] US8511606B1 discloses a method and an apparatus for charging batteries in unmanned aerial vehicles (UAVs) wherein transmission of electrical energy from the charging station to the battery of the aerial vehicle is inductive.
[0006] US7543780B1 discloses a further method for charging unmanned aerial vehicles (UAVs) wherein the UAVs include charging contacts for energy transmission from energy transmission lines.
[0007] Hence, in the view of this, there is a need for a system and method for autonomously charging the charge storage device such as rechargeable, multi-chemistry battery packs (Li-ion, Li-Po, Ultracapacitor/ Supercapacitor, etc.,) including multiple cell configurations used in many mobile units like Unmanned Aerial Vehicles (UAVs), Unmanned Ground Vehicles (UGVs), Electric Vehicles (EVs) and any other charge storage devices thereof. Further there is a need for a system and method for autonomously charging a charge storage device to its full potential, thereby removing constraints on an allowable length of wire from charger to battery pack. Furthermore, there is a need for a system and method for autonomously charging a charge storage device thereby reducing the number of wires, while ensuring balanced charging. Still further, there is a need for automating the charging process without any human intervention. Furthermore, there is also a need to minimize the weight and size of the payload of the autonomous charging system, which is to be placed on the mobile consumer end.
[0008] The above-mentioned shortcomings, disadvantages and problems are addressed herein, and which will be understood by reading and studying the following specification.

[0032] According to one embodiment of the present invention, the power path comprises contact-based, inductive, and/or far-field wireless power transfer. Correspondingly, the communication path comprises wire-based on power line communication or wireless based including Wi-Fi, Bluetooth Low Energy (BLE), Radio-frequency Identification (RFID), or Near-field Communication (NFC). The wired communication is triggered by the docking of the mobile consumer onto the pad and the wireless communication is triggered by monitoring the recharge required state of the mobile consumer. The mobile consumer includes Unmanned Aerial Vehicles (UAVs), Unmanned Ground Vehicles (UGVs), Electric Vehicles (EVs), and any other charge storage devices thereof. The protocol and the triggering event for initiating the communication between the battery system and the charger system depend on the preferred communication path, which is wired or wireless, and also the application.
[0033] According to one embodiment of the present invention, the battery system is retrofittable on any existing mobile consumer. Further, the power path and the communication path initiate communication between the charger system and the battery system, to select a charging profile of the battery system by the charger system, such that the charging profile of the battery system is selected by the charger system by using the log information of the various battery pack maintained by the charger system.

[0035] According to one embodiment of the present invention, the charger system and the battery system embedded in the mobile consumer align and connect autonomously using the power path and communication path. For a wired or contact-based power path and communication path, the battery end control system of the battery pack needs to make a 2-point contact with the charger end control system of the charger system.

[0037] According to one embodiment of the present invention, the charger system compensates for any losses which occur in the power path, by using accurate SoC data shared over the communication path and ensures complete charging of the battery system. The charger system gets the required real-time parameters of the battery system over the communication path and uses an algorithm to set an initial charging profile (CC0, CV0) of the battery system. As the CC0 charging profile starts, the algorithm accounts for the voltage drop in the wires based on the data from the battery system. The set charging profile gets updated based on the parameters from the battery system to compensate for the losses that occur in the power path to and thereby ensures full charge of the battery pack.
[0038] According to one embodiment of the present invention, the system also supports a plurality of battery configurations without any change in the hardware and firmware of the system. The system supports battery voltage in the range of 10V to 60V and a capacity up to 40 AH. Furthermore, the plurality of battery configuration includes connecting the battery packs in series and parallel combinations for complete charging.

The method comprises meeting an energy requirement of a mobile consumer by a battery system and constantly monitoring the status and health parameters of the battery system for optimizing the operation of the mobile consumer.
