[0002]Existing fire-resistant batteries are mainly made of flame-retardant materials selected from materials or coated with flame retardants on the surface of materials to achieve flame-retardant and fire-resistant effects. The battery box is generally integrated Once the battery is set on fire, it is difficult to control. If the fire from the inside of the battery often spreads to the outside of the battery box, causing other components to catch fire, people will find the fire and take fire-fighting measures
The wires in the prior art are connected to the battery box, there is no blocking device during the period, once a fire occurs, the circuit is difficult to operate

The invention discloses a fireproof battery assembly for a new energy automobile, and relates to the technical field of new energy automobile batteries. The fireproof battery assembly comprises a base and an end cover mounted on the base in a matched manner, wherein the base and the end cover form a closed cavity, a plurality of battery modules are uniformly distributed in the base, and gaps formed by different battery modules and the inner wall of the base are filled with buffer parts; and a plurality of cavities I and cavities II which are distributed around the battery module are formed in the buffer part, are distributed at intervals, and are filled with flame-retardant gas. According to the fireproof battery assembly, the buffer parts are filled among different battery modules or in gaps formed between the battery modules and the inner wall of the base, so that deformation explosion of a battery pack inside the battery modules caused by extrusion among different battery modules or between the battery modules and the inner wall of the base in a vehicle driving process are effectively avoided, and the safety in the driving process is ensured.
Description
technical field [0001] The invention belongs to the technical field of new energy vehicle batteries, and in particular relates to a fireproof battery assembly for new energy vehicles. Background technique [0002] Existing fire-resistant batteries mainly select flame-retardant materials from materials or coat flame-retardant materials on the surface of materials to achieve flame-retardant and fire-resistant effects. The battery box is generally integrated, making it difficult to control the battery once it catches fire. , Often spread to the outside of the battery box, causing other components to catch fire, people will find the fire and take fire-fighting measures. The wires in the prior art are connected to the battery box without a blocking device, and once a fire occurs, the circuit is difficult to operate. Based on this, there is an urgent need in the existing market for a fire-resistant battery assembly for new energy vehicles that can prevent and control all aspects ...
