Abstract: A power supply system that includes a traction battery, and a secondary battery that includes one or more hybrid modules having one or more low temperature chemistries. The power supply system also has one or more temperature sensors, and a switching device that connects or disconnects the secondary battery or the traction battery from a high-voltage DC (Direct Current) bus of an electric vehicle based on measurements of the one or more temperature sensors.

Abstract: A battery pack that includes an enclosure having at least four sidewalls and a base. An array of cells is arranged on the base, with each of the cells having a large wall surface and a small wall surface. The cells are arranged such that the large wall surfaces are parallel to each other. Components of the enclosure are made from an extrusion process and are mechanically attached or welded together. A base of the enclosure has fluid channels formed from the extrusion for use in cooling the array of cells.

Abstract: Disclosed herein, is a battery module that comprises an encapsulant material exhibiting improved thermal transfer and heat dissipation characteristics. In one example embodiment, the battery module comprises a “stack” of cells, wherein at least some of the cells, and optionally each cell, is not separated by a metal plate or tab-shaped heat sink layer, and instead, the cells are substantially surrounded by an encapsulant material and stacked directly upon one another.

Abstract: The disclosure relates to a method for determining the aging of an electronic interrupter element which is configured to open and close a power circuit. The method according to the disclosure comprises the following steps: a) initializing an aging counter NWear, b) determining the amount I of a current which flows through the electronic interrupter element upon opening the power circuit, c) determining a current-dependent aging value Nwear (I) from the amount I of the current, d) refreshing the aging counter NWear using the current-dependent aging value Nwear (I). The disclosure further relates to a computer program and to an apparatus for determining the aging of an electronic interrupter element and to a battery management system which are in particular configured to carry out the method.
