A bus bar assembly includes a nonconductive terminal cap that is configured to secure to an electrically conductive terminal via an attachment feature. The terminal cap has a slot that is configured to expose a terminal portion of the terminal in an assembled condition. A bus bar has an end that is configured to be received in the slot in the assembled condition in which the end is in electrical contact with the terminal portion of the terminal. A nonconductive shroud encloses the bus bar. The end extends through shroud.

A connector apparatus for a battery includes: a connector block assembly mounted in a battery case of a battery assembly, and including first and second electrodes facing the interior of the battery case; and a header assembly releasably mounted to the connector block assembly, and including first and second terminals connected to the first and second electrodes, respectively. The header assembly is exposed to the exterior of the battery case and the first and second terminals are electrically connected to terminals of a mating connector, respectively.

A battery module adapter for a vehicle or other equipment including at least one battery module and a housing assembly having a pair of battery terminals and a metal receiver functioning as an electrical connector defining a receptacle for receiving the battery module. The exterior dimensions of the housing assembly may be the same as the exterior dimensions of a standard battery.

A pole cap for a battery pole of a battery has a sleeve-like contacting portion, which has an outer periphery widening conically in the direction of the battery pole and tapering conically in the direction of the battery pole. A terminal is formed as a double-walled terminal sleeve having an inner wall and an outer wall, both designed to be supported by a collar, where the walls form an annular gap for positively receiving the sleeve-like contacting portion of the pole cap and where the gap tapers in the direction of the collar.

A receptacle connector device for electrical vehicle use in accordance with the present invention is disposed at a battery terminal of an electric vehicle and is connected to a plug connector in a charging station. The receptacle connector comprises an insulating body and a plurality of conducting elements. The insulating body is made of waterproof plastic materials and the plurality of the conducting elements are made of metal materials. The insulating body has a plurality of concentric circular grooves and a transverse portion. The plurality of the conducting elements are respectively disposed in the plurality of the concentric circular grooves, characterized in that: each of the plurality of the conducting elements forms a rough surface, thereby to enlarge contact area between the plurality of the conducting elements and the insulating body in moulding process for firm combination of plastic and metal materials.

A bus bar assembly includes, among other things, a nonconductive terminal cap that is configured to at least partially surround an electrically conductive terminal. The terminal cap has a perimeter wall that is configured to circumscribe at least a portion of the terminal to provide a gap that is configured to expose the terminal. The terminal cap includes a first attachment feature. The terminal cap also includes a bus bar that has an end that is configured to mechanically and electrically engage the terminal in an assembled condition. The terminal cap further includes a nonconductive shroud that encloses the bus bar. The shroud includes a second attachment feature that is configured to removably engage the first attachment feature in the assembled condition to secure the shroud to the terminal cap.
