Module-to-module power connector between battery modules of an energy storage system and arrangement thereof

Abstract

An embodiment is directed to a module-to-module power connector configured to form connections between battery modules installed in a battery housing of an energy storage system. The module-to-module power connector includes electrical interfaces and busbar(s) configured to form one or more electrical connections terminals of adjacent battery modules. The busbar(s) is flexibly configured to permit a defined range of movement of the electrical interfaces during insertion of the respective battery modules into respective battery module compartments. The module-to-module power connector may further be arranged inside in a tunnel space, whereby holes are defined in a battery module mounting area housing the battery modules that open into the tunnel space.

1 . A battery module of an energy storage system, comprising:
 a plurality of battery cells;   a positive terminal; and   a negative terminal,   wherein, upon the battery module sliding into a battery module compartment, at least one of the positive terminal and the negative terminal is configured to be aligned with an electrical interface of a module-to-module power connector so as to form an electrical connection therebetween.   
     
     
         2 . A method of installing battery module into an energy storage system, comprising:
 sliding the battery module into a battery module compartment,   wherein the sliding continues at least until a positive terminal and/or a negative terminal of the battery module forms an electrical connection with an electrical interface of a module-to-module power connector.   
     
     
         3 . The method of  claim 2 , further comprising:
 disconnecting the electrical connection by sliding the battery module out of the battery module compartment.
