Abstract: In implementations, a high-voltage power system may include circuitry and a cell-to-pack battery that is operatively connected to the circuitry. The cell-to-pack battery has: a cell arrangement including one or more cells, the cell arrangement configured to store energy for conversion into electrical energy for use in the high-voltage power system; a thermal management system having at least one of a first cooling plate arranged at a first side of the cell arrangement and a second cooling plate is arranged at a second side of the cell arrangement; and a modular open frame with which to secure the cell arrangement and the thermal management system, the modular open frame including a manifold for vent gas collection and an electrical box that houses a majority of electrical components for the battery pack, each of the manifold and the electrical box being connectible to the cell arrangement.

Abstract: In an electrified vehicle, such as a battery electric vehicle, those with a hybrid powertrain, range extended electric vehicles, or hydrogen powered vehicles, integration of the battery may mean that space is very constrained. Typically this means that there is no feasible method to lift the battery to disengage it from the vehicle or to operate any engagement catches or locks etc. The disclosure provides a roller arrangement which has no translation or actuator requirements in order to allow the battery to have reduced frictional engagement with the battery compartment during installation or removal, and also to be well engaged with the battery compartment once installed. Rollers are provided which drop into recesses in the battery compartment at which point they are removed from load bearing engagement and thus, the recesses serve to locate the battery into the installed state in the compartment.
