Problems solved by technology

[0011] Likewise, too high a temperature is detrimental to a lithium-ion battery cell and too high an operating temperature can cause electrolyte decomposition in the battery cell and, for example, layer deposition on the anode, which strongly increases the internal resistance of the cell.

Abstract

The invention relates to a battery system (1) for a motor vehicle. The battery system comprises a housing (2) for accommodating a single battery (4), a system component for holding and contacting withthe single battery (4) accommodated in the housing (2), and heating equipment (6) for heating the single battery (4) accommodated in the housing (2), wherein the heating equipment (6) is applied to the system component and / or the housing (2) and / or the single battery (4) in a material matching manner.

Description

technical field [0001] The invention relates to a battery system for a motor vehicle and to a heating device for a motor vehicle battery. Background technique [0002] Battery systems for motor vehicles are known, wherein the battery system is used not only as an auxiliary battery system but also as a main battery system. [0003] Consumers in the motor vehicle are supplied with electrical energy by means of the auxiliary battery system, which is not directly used to drive the motor vehicle. Such auxiliary battery systems are known, for example, as starter batteries for internal combustion engines. Furthermore, control units, on-board computers, shutdown devices and other electrical consumers of the motor vehicle are supplied with electrical energy via such an auxiliary battery system, for example, as long as no other source is supplied with electrical energy, for example via a generator when the internal combustion engine is running. [0004] Furthermore, it is known in m...
