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

Embodiment 1

[0037] Such as Figure 1-7 , a battery module storage and charging and discharging box system for liquid-filled fire protection, including a box system composed of one or more boxes 1 and a power supply 2 connected to the box system, a liquid storage tank 3, and a control system Module 4; the box body 1 includes a warehouse door 5 located at the front end of the box body, a composite sensor 6 located at the top inside the box body, a fire sprinkler 7 and a charging socket 8 located inside the box body, and set on the side wall of the box body The chute 9, the tray 10 that can slide in the chute, the liquid storage box 12 that is arranged on the top opening of the tray for placing the battery 11; the charging socket 8 is connected to the controllable on-off switch 13 and then connected to the power supply 2 , the preferred controllable on-off switch of the present embodiment is a contactor; all fire sprinklers 7 are respectively connected with a control valve 15 and then aggreg...

Embodiment 2

[0047] Such as Figure 8 The difference from Embodiment 1 is that the charging socket 8 of this embodiment is located on the side wall of the liquid storage box 12 inside the box, and is connected to the controllable on-off switch 13 through the openings on the liquid storage box and the side wall of the box.

Embodiment 3

[0049] Such as Figure 9 The difference from Embodiment 1 is that the charging socket 8 of this embodiment is located at the bottom of the liquid storage box 12 inside the box, and is connected to the controllable on-off switch 13 through the openings opened on the liquid storage box, the tray, and the bottom of the box.

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...
