Abstract
A battery for an electric vehicle is disclosed. The battery may be a low voltage battery for powering low voltage systems. The battery may include a housing formed from at least two parts. For example, the housing may include a top portion that is sealed to a bottom portion. A plurality of rechargeable electrochemical cells may be disposed within the bottom portion. A printed circuit board and/or a bus bar may be disposed within the top portion. The housing can includes a desiccant and/or a two-way pressure valve extending through a surface of the housing. The valve may be used to prevent moisture ingress into an interior of the housing and/or may allow a pressure inside of the housing to equilibrate to the external air pressure.
