Abstract

The invention relates to a battery system (100) comprising at least one group of a plurality of aligned battery cells (80) arranged in a first direction (Y). Each of the battery cells (80) includes a vent (88). The battery system (100) also includes a fire extinguishing system (60) having a reservoir (61) for the fire extinguishing agent and at least one conduction device (72) for conducting the fire extinguishing agent, wherein the conduction device (72) is arranged such that conduction The device (72) is hit by an exhaust jet expelled from any vent hole (88) of the plurality of aligned battery cells (80), wherein at least one conductive device (72) is configured to be melted by the exhaust jet. The invention also relates to a cooling circuit (70) for a battery system (100) comprising at least one set of a plurality of aligned battery cells (80) in which Each includes a vent (88). The cooling circuit (70) includes: a conduction device (72) configured to conduct a non-combustible or flame-resistant coolant; and an evaporator (71) aligned with a first plurality (91) of battery cells (80) in thermal contact and configured such that the coolant absorbs heat from the first plurality of aligned battery cells (80). The conduction means (72) is arranged such that the conduction means (72) is hit by an exhaust jet expelled by any exhaust vent (88) of the first plurality (91) of aligned battery cells (80) and is configured to Melted by the exhaust jet.

Description

technical field [0001] The invention relates to a battery system with an improved fire extinguishing system and a cooling system for a battery system, in particular a cooling system with an integrated fire extinguishing system. Background technique [0002] A rechargeable or secondary battery differs from a primary battery in that a rechargeable or secondary battery can be repeatedly charged and discharged, whereas a primary battery only provides the irreversible conversion of chemical energy to electrical energy. Low-capacity rechargeable batteries are used as power sources for small electronic devices such as cellular phones, notebook computers, and camcorders, while high-capacity rechargeable batteries are used as power sources for hybrid vehicles and the like. [0003] Generally, a rechargeable battery includes an electrode assembly including a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode, ...
