Abstract: A battery pack includes three low-voltage units, output and interconnection terminals connected to the low-voltage units, and a conductor assembly including first and second conductors and an electrically non-conductive cover covering the first and second conductors. With the first conductor electrically connected to first and second interconnection terminals, and the second conductor electrically connected to third and fourth interconnection terminals, a voltage greater than a pre-determined voltage is present between two terminals. The conductor assembly is configured to remove the conductors together with the cover, thereby electrically disconnecting the conductors from the interconnection terminals; and to install the conductors together with the cover, thereby electrically connecting the conductors to the interconnections terminals, the cover covering the interconnection terminals.

Abstract: A battery pack includes at least two low-voltage units, a first conductor and a retention assembly. The first conductor is selectively electrically connected to the at least two low-voltage units such that a voltage between two conductors of the battery pack is greater than a pre-determined voltage. The retention assembly is configured to, with the first conductor electrically connected to the at least two low-voltage units, prevent disconnection of the at least two low-voltage units from each other. In response to the first conductor being electrically disconnected from the at least two low-voltage units, the retention assembly stops the first conductor from being electrically connected to the at least two low-voltage units.

Abstract: A battery pack with electromagnetic compatibility (EMC) for an electric vehicle is presented that includes a battery pack housing, at least one battery module enclosed within the battery pack housing, and an electronics assembly enclosed within the battery pack housing, in which the electronics assembly comprises a DC-DC converter and an electronics assembly casing, wherein at least one of the electronics assembly and battery pack housing includes an electromagnetic interference (EMI) shield to enable EMC. The electronics assembly includes a battery management system (BMS) circuit board and a DC-DC converter control circuit board and a DC-DC converter power electronics board. The electronics assembly is of substantially a same dimension of a battery module, in which the EMI shield comprises at least one of a metallic screen, metallic wires, a metallic tape, a metallic sheet, a metallic coating, paramagnetic materials, carbon based materials and metallic and/or carbon particle-infused composites.
