Abstract: Systems and methods disclosed herein include a portable air pump and inflator system comprising an electric air compressor, a compressor housing enclosing the electric air compressor, an air hose attached or attachable to an air outlet of the electric air compressor, and a housing base attached to the compressor housing. The housing base comprises a rigid base portion that is attached to the compressor housing and a plurality of flexible foot extensions that extend from the rigid base portion. The flexible foot extensions are configured to support the portable air pump and inflator system on a surface and dampen vibrations caused by the operation of the electric air compressor.

Abstract: Systems and methods disclosed herein include a portable air pump comprising an electric air compressor and a compressor housing enclosing the electric air compressor. The electric air compressor includes an electric motor, a piston cylinder, a piston, and a reed valve. The piston has a piston head within the piston cylinder and a piston rod attached to the electric motor. The piston head includes a piston valve that allows air to enter the piston cylinder. The reed valve is configured to allow air to pass from the piston cylinder to an air outlet while the portable air pump and inflator system is in operation. The piston head further includes a relief channel that defines an opening through the piston head to allow air pressure to escape from within the piston cylinder.

Abstract: A battery management system (BMS) for use in a rechargeable battery includes a printed circuit board (PCB) having two or more electrically conductive metal plates, the two or more electrically conductive metal plates located adjacent to and spaced apart from each other on the PCB providing an electrically isolating gap between the two or more electrically conductive metal plates; and multiple electronic components of the BMS electrically connected between the two or more electrically conductive metal plates.

Abstract: A battery management system (BMS) having a printed circuit board (RGB) with a diagonal arrangement for use in a Li-ion battery, a Li-ion battery having a battery management system (BMS) having a printed circuit board (RGB) with a diagonal arrangement, and a BMS having a printed circuit board with diagonal arrangement method.

Abstract: A battery, for example, a rechargeable battery (e.g. lithium ion battery) having a casing with battery terminals. The casing, for example, includes an upper section, middle section, and lower section connected together. The battery can be connected to one or more battery trays having the same height or different heights for various applications.
