Problems solved by technology
[0012] Since the hot exhaust gas may include metal parts of the battery cells in addition to graphite, thermal runaway in one battery cell may cause a short circuit, causing continuous thermal runaway of other battery cells leading to battery (battery group), battery system and vehicle are completely damaged
[0013] Because all the cells or modules are in the same battery case, contamination from graphite and metal parts can affect most of the cells or modules of the battery and cause a short circuit
Depending on the position of the battery cell relative to the case vent valve during thermal runaway, different airflows may occur and affect different parts of the battery

The present invention refers to a battery system, the battery system comprising a plurality of battery cells and a battery housing, wherein the battery housing comprises a chamber arranged between a bottom cover and top cover of the battery housing, wherein the chamber accommodates the plurality of battery cells; and at least one sidewall member connecting the bottom cover and the top cover, wherein the at least one sidewall member extends along an outer boundary of the chamber and comprises a channel inside the sidewall member and apertures connecting the chamber with the channel, wherein the apertures are arranged in a top half of the channel such that at least a bottom half of the channel is adapted for collecting solid matter; wherein the battery system is adapted such that in case of a thermal runaway, a venting gas vented from at least one of the battery cells is directed along at least one venting path leading from the chamber, through at least one of the apertures and the channel within the at least one sidewall member to an environment of the battery system.
Description
technical field [0001] The invention relates to a battery system configured for separating solid matter from exhaust gases in the event of thermal runaway. Furthermore, the invention relates to a vehicle comprising the battery system. Background technique [0002] In recent years, vehicles for transporting goods and people using electric power as a motion energy source have been developed. Such an electric vehicle is an automobile driven by an electric motor using energy stored in a rechargeable battery. Electric vehicles may be powered solely by batteries, or may be in the form of hybrid electric vehicles (hybrid vehicles) powered by, for example, gasoline generators. Additionally, vehicles may include a combination of electric motors and conventional internal combustion engines. Typically, an electric vehicle battery (EVB) or traction battery is a battery used to power the drive of a battery electric vehicle (BEV). Electric vehicle batteries are distinct from starting,...
