Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, specifically a storage cabinet for power battery packs of new energy vehicles. Background Technology

[0002] A new energy vehicle power battery pack is an integrated, high-voltage, rechargeable energy storage system specifically designed to provide the electrical energy required for the drive motor of a new energy vehicle. It consists of multiple battery cells connected in series and parallel to form a battery module, and then multiple modules are integrated and packaged together with a battery management system, thermal management system, electrical system, structural components, etc., to form a physical and functional whole unit.

[0003] Currently, storage cabinets are commonly used to store multiple battery packs together. However, during storage, due to the dense arrangement of individual cells, if a cell experiences thermal runaway due to a short circuit, compression, or overcharging, the splashing of high-temperature electrolyte or the release of gas can trigger a chain reaction in adjacent cells, causing the fire to spread rapidly and posing a certain safety hazard.

[0004] Therefore, we propose to design a storage cabinet for power battery packs in new energy vehicles. Utility Model Content
