Abstract: A vehicle includes a chassis, a vehicle body, a hydraulic system, a battery, and an electric power take-off system. The electric power take-off system includes an inverter electrically coupled to the battery, a motor electrically coupled to the inverter and configured to power the hydraulic system, a cooling circuit in thermal communication with the inverter, and a fluid pump configured to pump cooling fluid through the cooling circuit.

Abstract: A refuse vehicle includes a chassis, an energy storage device, a body, a first electric power take-off system, and a second electric power take-off system. The energy storage device is supported by the chassis and is configured to provide electrical power to a prime mover. Activation of the prime mover selectively drives the refuse vehicle. The body is supported by the chassis. The first electric power take-off system is coupled to at least one of the body and the chassis, and includes a first motor that is configured to drive a first hydraulic pump to convert electrical power received from the energy storage device into hydraulic power. The second electric power take-off system is coupled to at least one of the body and the chassis, and includes a second motor that is configured to drive a second hydraulic pump to convert electrical power received from the energy storage device into hydraulic power.

Abstract: An assembly includes a cell stack, the cell stack including a plurality of cells, the cells separated by cell spacers. The assembly also includes a compression pad at each end of the cell stack and a lithium-ion battery module strap assembly, the cell stack and compression pads positioned within the lithium-ion battery module strap assembly. The lithium-ion battery module strap assembly includes a case, the case including a bottom and two sides, end caps at each end of the case, and at least one strap, the strap positioned around the cell stack and connected to each end cap.

Abstract: An energy storage system comprising a battery row having first and second row ends, first and second end pieces abutting the first and second row ends, respectively, an end piece retaining strap encircling the end pieces and the batteries therebetween and applying a first compressive force thereto, thereby defining a battery assembly, the battery assembly having external corners, first and second foam pieces enclosing at least the external corners of the battery assembly; a foam retaining strap encircling the foam pieces so as to maintain the foam pieces in a desired position relative to the battery assembly, thereby defining a battery module, and an enclosure having at least one battery module retained inside the enclosure. The foam pieces may be configured to reduce or enhance the rate of heat flow between the batteries and the operating environment.

Abstract: An apparatus and method for filtering a fluid is provided. The apparatus includes a filtration unit having an inlet and hollow fiber membranes. The hollow fiber membranes are each formed from an elongated tube having an exterior surface and an interior surface. The hollow fiber membranes are configured to separate the filtration unit into a permeate side that allows permeate to exit the filtration unit through a permeate outlet and a retentate side that allows retentate to exit the filtration unit through a retentate outlet. The hollow fiber membranes include a coating linked to the exterior surface or interior surface of the hollow fiber membranes. The coating includes a poly electrolyte electrostatically coupled to the charged exterior surface or the charged interior surface.
