Intelligent explosion-proof charging cabinet, lithium battery, electric vehicle battery storage cabinet with temperature control alarm, fire extinguishing and exhaust system

Description :

　　Intelligent explosion-proof charging cabinet is a centralized charging and storage safety facility designed specifically for high-risk energy storage equipment such as lithium batteries and electric vehicle batteries. It solves the risk of fire and explosion caused by battery thermal runaway in traditional charging methods by building a closed-loop safety system of "monitoring warning disposal isolation". This device is typically used in residential property management, food delivery stations, factory workshops, underground garages, and other scenarios. Its core functions include real-time temperature monitoring, smoke sensing alarms, automatic ventilation and heat dissipation, and active fire suppression with hot aerosols. It ensures that the device can intervene and handle abnormal battery heating or smoking in the early stages, preventing accidents from expanding and providing a physical isolation space that complies with fire safety regulations for high-density battery storage.

　　The intelligent explosion-proof charging cabinet is made of high-strength cold-rolled steel plate bent into shape, and the surface is acid washed and phosphated, then sprayed with weather resistant yellow epoxy powder, which has anti-corrosion and anti rust properties. The internal layer board is made of galvanized material, which has strong load-bearing capacity and resistance to electrolyte corrosion. The electrical system is equipped with a leakage switch protection to prevent short circuit and electric shock; The top integrated microcomputer real-time temperature controller has an accuracy of ± 1 ℃, and is paired with a high-level smoke alarm to achieve dual monitoring. The back of the cabinet is equipped with ventilation holes for exhaust fans, forming a negative pressure convection heat dissipation structure. The door lock adopts a dual lock control mechanism to enhance management security. Wear resistant and silent casters are installed at the bottom, two of which have braking functions, making it easy to move and fix on flat indoor surfaces, meeting the protection level requirements of relevant energy storage equipment safety standards such as GB/T 34015.

　　When selecting an intelligent explosion-proof charging cabinet, it is important to distinguish between ordinary metal cabinets and specialized security cabinets of this type. Ordinary cabinets only have physical storage functions and do not have active safety intervention capabilities. They are strictly prohibited from being used for lithium battery charging. This device is suitable for scenarios that require 24-hour unmanned charging, such as express logistics sorting centers or electric bicycle battery swapping cabinets. If the environment humidity is extremely high or there are strong corrosive gases present, it is recommended to customize a stainless steel liner version. For large capacity power battery packs, it is necessary to check whether the socket format (such as pin plug, Anderson plug) in the cabinet matches the battery interface, and confirm whether the single-layer load meets the weight requirements of the battery pack to avoid deformation of the laminate caused by overload and affecting the smooth flow of the heat dissipation duct.

　　The installation of intelligent explosion-proof charging cabinets should be placed in a dry, well ventilated, non flammable and explosive area, away from water sources and direct sunlight. Before use, it is necessary to check whether the grounding wire is reliably connected to ensure the effectiveness of the leakage protection module. In daily maintenance, the sensitivity of the smoke alarm should be tested once a month, and the dust accumulation at the inlet of the exhaust fan should be cleaned to prevent rapid temperature rise in the cabinet due to air volume attenuation. Regularly check the status and expiration date of the pressure gauge of the hot aerosol fire extinguisher to ensure normal eruption in emergency situations. Common faults such as abnormal display of temperature controllers are often caused by poor contact or damage of sensor probes, which need to be replaced in a timely manner; If the door leaf is not tightly closed, adjust the hinge screws or check the tongue position of the door lock to ensure the sealing of the cabinet and maintain stable internal airflow organization.
