MODULE-TO-MODULE POWER CONNECTOR BETWEEN BATTERY MODULES OF AN ENERGY STORAGE SYSTEM AND ARRANGEMENT THEREOF
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.
