U.S. PGPub 2021/0031638 A1 (hereinafter Lehmeier) as applied to claim 1 above, and further in view of Andrews, JR. U.S. PGPub 2014/0266004 A1 (hereinafter Andrews). Regarding Claim 5, The combined teaching of the Moon and Lehmeier references discloses the claimed invention as stated above in claim 1, but does not teach controlling use of the system. Andrews, however, teaches wherein the main control system board controls authentication to use the system, and control usage level depending on the authentication (Andrews, Para. [0056]). It would have been obvious to a person having ordinary skill in the art to understand that although Moon as modified by Lehmeier is silent as to user authentication, Moon would inherently incorporate some type of conventional user authentication commonly understood in the art. The user authentication taught by Andrews teaches one of the many conventional user authentication methods utilized in the art for authorizing the use of the charging system. A person of ordinary skill in the art would have been motivated to choose based on desirability, one of the many known conventional methods, such as the one taught by Andrews, to provide user authentication to the modular charger of Moon. Claim 21 is rejected under 35 U.S.C. 103 as being unpatentable over Moon U.S. PGPub 2019/0245356 A1 (hereinafter Moon) in view of Lehmeier et al. U.S. PGPub 2021/0031638 A1 (hereinafter Lehmeier) as applied to claim 1 above, and further in view of Kirschner U.S. PGPub 2021/0354578 A1 (hereinafter Kirschner). Regarding Claim 21, The combined teaching of the Moon and Lehmeier references discloses the claimed invention as stated above in claim 1, but does not teach further comprising an external connection to add an additional battery pack to the system and the plurality of battery packs. Kirschner, however, teaches further comprising an external connection to add an additional battery pack to the system and the plurality of battery packs (Kirschner, Figs. 2-3, Element 22; Paras. [0034] - [0040]). It would have been obvious to a person having ordinary skill in the art to understand that although Moon as modified by Lehmeier is silent as to adding an additional external battery pack, Moon would inherently incorporate some type of conventional power expansion method commonly understood in the art. The power expansion method taught by Kirschner, for using an external module to add to the power of the charger, teaches one of the many conventional power expansion methods utilized in the art for increasing the power for charging the battery of an electric vehicle. A person of ordinary skill in the art would have been motivated to choose based on desirability, one of the many known conventional methods, such as the one taught by Kirschner, to provide the added power of an add-on battery module to the modular charger of Moon. Response to Arguments Applicant’s arguments, see pages 6-7, filed February 20, 2026, with respect to the rejection(s) of claim(s) 1-25 under 35 U.S.C. §103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of a newly found prior art reference.
