Abstract: The present disclosure provides a busbar for a battery pack having a plurality of battery cells separated by respective thermal barriers. The busbar is configured to provide electrical connection between battery cells within the battery pack by way of electrical connection arrangements. The busbar further comprises a plurality of channels, each channel configured to receive a thermal barrier. Each channel includes a first portion sized to accommodate a thermal barrier and a second portion adjacent an opening of the channel which is wider than the first portion of the channel such that, during assembly of the busbar into a battery pack, the second portion of each channel is configured to guide a thermal barrier into the respective channel.

Abstract: A traction battery pack assembly includes a busbar assembly having at a frame and at least one busbar. The frame includes a plurality of fingers. A locking bar has a plurality of apertures that are each configured to receive a portion of one or more of the fingers to constrain the busbar assembly.

Abstract: A method of enhancing the flow of hydrocarbon fluids from small flow conduits (12) in a subterranean reservoir rock formation (10) that have traditionally not been propped in association with a fracturing treatment of the formation (10), the method including the steps of introducing a first pressurized fluid into the formation at a pressure that is sufficient to expand the pre-existing small flow conduits (12) and introducing into the pressure-expanded small flow conduits (12) a first portion of a relatively small particulate propping agent (16); simultaneously with the fracturing of the formation, or immediately thereafter, introducing a second portion of a relatively small particulate propping agent (16) into expanded pre-existing small flow conduits and into any new small flow conduits that are formed by the fracturing of the formation; and reducing the hydraulic pressure on the formation, whereby the small flow conduits are held open by propping agent particles.

Abstract: A method and composition for stimulating petroleum production from carbonate reservoirs by employing chelating agents, such as EDTA, which are in particulate form rather than aqueous solutions of chelating agents. The use of particulate chelants, which are relatively unstable in acidic solutions, results in a stimulation fluid with a very high dissolution capability.
