Housing for receiving unit battery cells i.e. lithium ion cell, of traction battery of electrically driven vehicle, has material layers, where one material layer is provided with polymer material, and hollow spaces formed between two layers

摘要

The housing has a wall (4) with a set of material layers (5, 6, 8), where one of the material layers is provided with a polymer material. A set of hollow spaces (7, 9) is formed between two of the material layers. A cooling fluid flows in the hollow spaces, and an electrically conductive fluid is arranged in the set of hollow spaces. A chemical or neutralizing agent is arranged in one of the set of hollow spaces.
