The invention relates to an electric battery (1) for a motor vehicle which is electrically or partly electrically driven or a movable or stationary unit, having a battery housing (5) and a plurality of battery cells (2) arranged therein. The aim of the invention is to allow such an electric battery (1) to be produced with minimal costs and technical structural complexity while still having a high degree of operational reliability. This is achieved in that the battery housing (5) is made of an expanded or foamed plastic.

A battery device has a battery housing, a plurality of battery cells arranged therein, around which a dielectric thermal management medium can flow in the battery housing at least in some areas in an immersion circuit inside the battery for the purpose of immersion thermal management, and thermally conductive elements. The thermally conductive elements are each arranged between two adjacent battery cells which each bear with at least one side against the respective thermally conductive element in thermally conductive contact with the latter. The thermally conductive elements here project in at least one direction beyond the battery cells and through a housing wall of the battery housing to the outside. The thermal management medium can likewise flow around those sections of the thermally conductive elements running from the battery cells to the corresponding housing wall.

A device for cooling battery cells of a traction battery which are arranged in at least two battery cell planes positioned one on top of the other. The device includes a first cooling plate which is arranged between a first battery cell plane and a second battery cell plane and is in thermal contact with the battery cells of the first and the second battery cell plane. Second cooling plates are arranged within the first and the second battery cell plane and are in thermal contact with multiple battery cells of the respective battery cell plane. A cooling fluid inlet is formed on a first side of the first cooling plate. A cooling fluid outlet is formed on a second side of the first cooling plate. The cooling fluid flows from the cooling fluid inlet into the first cooling plate on the first side of the first cooling plate.

Embodiments of this application provide a battery management system (BMS) wake-up method, a BMS wake-up apparatus, and a storage medium, and pertains to the field of battery safety technologies. In this application, before a BMS hibernates, a wake-up threshold corresponding to first sampling information is determined based on an obtained extremum of the first sampling information of a battery cell. After the BMS hibernates, a sampling chip collects second sampling information of the battery cell when the BMS is hibernating, and transmits a wake-up signal to the BMS when it is determined that the second sampling information of the battery cell reaches the wake-up threshold. In this way, the BMS can be woken up in a timely manner by the wake-up signal, and therefore the BMS can find battery safety problems in a timely manner.
