Abstract: A pressure relief cap for a battery module includes a body. The body includes a base portion defining a first thickness. The body also includes a first circular projection defining a second thickness that is lesser than the first thickness of the base portion. The first circular projection extends orthogonally from the base portion. The body further includes a second circular projection extending orthogonally from the base portion. The second circular projection is concentric with the first circular projection.

Abstract: A reduction device includes a housing defining an input chamber configured to receive exhaust from a power source, an output chamber, an exhaust channel configured to direct the exhaust from the input chamber to the output chamber, and a longitudinal axis. The reduction device also includes a treatment unit disposed in the exhaust channel and along the longitudinal axis. The treatment unit is configured to at least partly remove pollutant species from the exhaust. The reduction device also includes an attenuation component disposed in the housing and radially outward of the treatment unit. The attenuation component is fluidly connected to the exhaust channel, and is configured to attenuate a range of frequencies corresponding to operation of the power source. Additionally, the exhaust channel prohibits exhaust entering the input chamber from exiting the housing without passing through the treatment unit.

Abstract: A battery module includes a housing. The housing includes a first end plate and a second end plate. The housing further includes a first side plate coupled to the first end plate and the second end plate. The housing includes a second side plate opposite the first side plate. The housing also includes a cover extending between the first end plate and the second end plate. The housing further includes a plurality of projections extending from the base surface of the cover. The plurality of projections are arranged to define a recess. The battery module also includes a plurality of battery cells secured within the housing between the first end plate, the second end plate, the first side plate, and the second side plate.

Abstract: A fluid system for a machine includes a tube assembly and a sock filter enveloping the tube assembly. The fluid system also includes a filter protector adjacent to a fastener in the tube assembly and including a first connector fitted with a first tube, a second connector fitted with a second tube, and a wall that arcs between the first connector and the second connector and limits contact between a sock filter enveloping the tube assembly and the fastener.
