Non-welding joinder of exterior plates of a battery module

A battery module configured for insertion into a battery module compartment of an energy storage system, the battery module comprising:

• a first exterior plate configured with a male joining section arranged at a first edge of the first exterior plate;
• a second exterior plate that is adjacent and substantially perpendicular to the first exterior plate and configured with a female joining section arranged at a second edge of the second exterior plate;
• and
• at least one data port configured to connect to at least one corresponding data port of the battery module compartment, upon insertion of the battery module into the battery module compartment, to place the battery module in communication with a battery junction box (BJB),
• wherein the first and second exterior plates are joined together via the male and female joining sections without welding,
• wherein the first and second exterior plates are arranged on different sides of an exterior frame of the battery module, and
• wherein, upon insertion of the battery module into the battery module compartment, the first and second exterior plates of the battery module are encapsulated within the battery module compartment with the battery module compartment comprising at least a liquid-tight seal and without the first and second exterior plates being integrated as exterior walls of the battery module compartment.
