摘要： The energy storage module of the battery pack is located in the housing, the heat insulation panel is located between the energy storage module and the housing, the heat insulation panel includes a heat insulation layer and an outer packaging layer. The outer packaging layer wraps the outside of the heat insulation layer and compresses a thickness of the elastic heat, insulation layer, and a ventilation channel is formed between the heat insulation panel and the energy storage module. The outer packaging layer is configured to release compression of the elastic heat insulation layer when the energy storage module reaches a thermal runaway temperature, and the heat insulation panel is filled between the housing and the energy storage module, thereby slowing down a speed at which heat passes through a side panel and spreads to the outside of the battery pack along the ventilation channel.

摘要： An battery cell, a battery cell hazard detection system, and a method for detecting a hazardous battery condition at an early stage is provided. An example battery cell may include a battery cell package defining an interior compartment of the battery cell. The battery cell may further include an anode disposed in the interior compartment of the battery cell, a cathode disposed in the interior compartment of the battery cell, and a separator positioned between the anode and the cathode. A chemical coating may be disposed on the surface of the separator, such that, in an instance in which an interior temperature within the interior compartment of the battery cell exceeds a pre-determined maximum operating temperature, the chemical coating may evaporate, forming a chemical coating vapor indicating to a sensing device the hazardous condition of the battery cell.

摘要： A cooling device for an electrical energy store, having a heat sink for arranging on one side of a cell assembly formed of energy storage cells of the electrical energy store and for cooling the energy storage cells is provided. The heat sink has openings for aligned arrangement so as to form degassing elements of the energy storage cells. The openings form a degassing duct for a hot gas of the energy storage cells that leaks via the degassing elements. The cooling device has intermediate cooling elements for arranging in clearances of the cell assembly between the energy storage cells in order to compensate for a loss of cooling surface that results from the openings of the heat sink. The intermediate cooling elements are arranged on the heat sink and are designed to dissipate waste heat from the energy storage cells to the heat sink.

摘要： Traction battery pack designs are disclosed for use in electrified vehicles. Exemplary traction battery packs may include an outer enclosure assembly establishing an interior, and a battery array housed within the interior. A pressure equalization device may be disposed within a wall of the outer enclosure assembly and may be configured to both equalize the pressure inside the battery pack during normal battery operations and to prevent the unintended release of battery vent byproducts during battery thermal events.
