Abstract
Presented are finger-proof electrical terminals for battery assemblies, methods for making/using such electrical terminals, and vehicles with battery modules having finger-proof electrical terminals for bolted busbar connections. A battery assembly includes one or more electrochemical battery cells and one or more electrical terminals each electrically connected to the battery cell(s) and having a contact face to electrically connect the battery assembly to an electrical connector. A threaded nut attaches each electrical terminal to one of the electrical connectors. An electrically insulating nut cap is attached to each threaded nut. A battery housing, which stores therein the battery cell(s), includes an electrically insulating housing wall with one or more terminal jackets each mounting therein one of the electrical terminals. Each terminal jacket has a jacket window that circumscribes one of the nut caps, spaced therefrom by a predefined clearance sufficient to expose the contact face of the electrical terminal.
