Filling fire-fighting battery module storage and charge-discharge box system

Abstract

The invention discloses a filling fire-fighting battery module storage and charge-discharge box system which is applied to the field of new energy automobile batteries and comprises a plurality of boxes, a power supply, a liquid storage tank, a control module, a controllable on-off switch and a control valve. Each box comprises a warehouse-out door, a composite sensor, a fire sprinkler, a charge socket, a tray, a sliding groove and a liquid storage box. At present, when a storage bin catches fire, fire extinguishing media are usually sprayed to a battery portion on fire, flames can only be suppressed by the method, but the fire cannot be thoroughly extinguished. According to the system, when the storage bin catches fire, the composite sensor transmits detected pyrotechnic signals to the control module, the control module controls disconnection of a circuit and connection of a pipeline by the aid of the controllable on-off switch and the control valve, the liquid storage box in each boxis filled with water until a battery is completely submerged, and thorough fire-fighting extinguishing is performed without affecting other storage bins.

Description

technical field [0001] The invention belongs to the field of new energy vehicle batteries, and in particular relates to a battery module storage and charging and discharging box system of a liquid-filled fire-fighting system. Background technique [0002] With the advancement of the national energy conservation and emission reduction policy and the increasing popularity of new energy vehicles, the share of electric vehicles in the automobile market has become larger and larger, and there is a trend of continuing to expand their applications. As an important part of electric vehicles, batteries are the energy source of electric vehicles. The charging and energy storage of batteries is an extremely important part of the development of electric vehicles. At present, it is common to use containers to store energy in battery packs and to charge spare batteries for battery replacement. Many of these solutions use a multi-position design, and the battery modules in each position ar...

AI Technical Summary

Problems solved by technology

Since most lithium-ion batteries catch fire, conventional fire extinguishing media are often sprayed onto the burning battery, but this method can only suppress the flames and cannot completely extinguish the fire. The effective fire extinguishing method is to use water or sand to extinguish the fire. Completely submerge or bury the battery, completely isolate the battery from air / oxygen for complete fire extinguishing
