It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Since some tiny defects of the lithium battery are not detected during manufacturing, the internal short circuit of the lithium battery can occur during the use process. The internal short circuit can convert the electric energy stored in the lithium battery into heat energy, so that the internal temperature of the lithium battery is too high, and thermal runaway of the lithium battery is further caused. Lithium batteries release a large amount of heat when thermal runaway occurs, resulting in high temperatures. If this heat is transferred to a nearby lithium battery to cause its temperature to be too high, thermal runaway spreads. At this moment, heat insulation is needed to avoid the generation of thermal runaway propagation, but the heat insulation is contradictory to the heat dissipation requirement of the lithium battery in normal operation, and the prior art is difficult to meet the heat dissipation requirement at the same time.
Therefore, the embodiment of the invention adopts an innovative scheme, changes the resistance of the heat generated by thermal runaway into the sparse, and aims at the characteristics of the energy storage application of the lithium battery to purposefully solve the problem of the contradiction.

Meanwhile, the water inlet is also connected with a water inlet pipe, and the water outlet is also connected with a water outlet pipe. Normally, the water inlet is in a closed state.
Under the condition that thermal runaway appears in the lithium cell in a certain subrack like this, pour into this subrack through the cooling water of water inlet in with the inlet tube, simultaneously because the outlet is located the top of water inlet and is less than the up end of lithium cell, unnecessary cooling water can discharge from the outlet in the drain pipe, thereby the cooling water can contact the surface of lithium cell as much as possible and can not touch the electrode of lithium cell, guaranteed that the water and electricity separation can not cause under the prerequisite that the lithium cell intake damaged, the heat that a large amount of lithium cell thermal runaway produced is taken away to the heat absorption capacity of water, effectively prevent heat conduction to neighbouring battery heat-forming stretch, and then can effectively avoid the emergence of energy storage station lithium cell conflagration.

Under normal conditions, the air can be followed and passed through in this through-hole, can carry out ventilation cooling to the inside lithium cell of plug-in box. And under the condition that thermal runaway appears, because hollow space bar has sufficient intensity, can bear the pressure that the lithium cell is bloated, by extrusion deformation and can not invade the space of reserving between the lithium cell when preventing the lithium cell from bloating, the cooling water can smoothly pass through in the inside through-hole of hollow space bar, thereby the heat that a large amount of lithium cell thermal runaway produced is taken away to the heat-absorbing capacity of utilization water, effectively prevent that heat conduction from spreading to adjacent battery formation heat, and then can effectively avoid the emergence of energy storage station lithium cell conflagration.

In this embodiment, in order to accurately and quickly determine which lithium battery in which plug-in box in the cabinet body has temperature abnormality and the possibility of thermal runaway exists, a plurality of first temperature sensors and a plurality of second temperature sensors are respectively arranged. Meanwhile, Battery Management Units (BMUs) are correspondingly arranged in the plug boxes respectively, wherein the BMUs are components of a Battery Management System (BMS).
Preferably, each first temperature sensor is arranged on the upper end face of each lithium battery of each plug-in box, each first temperature sensor is connected with a corresponding Battery Management Unit (BMU) in the plug-in box, each corresponding Battery Management Unit (BMU) is connected with a fire-fighting controller through a communication bus, and the acquired temperature information of each lithium battery can be transmitted to the fire-fighting controller in time. Simultaneously, the bottom outside at each subrack has also set up second temperature sensor respectively, and makes each second temperature sensor all be connected with the fire control controller, can in time transmit the temperature information of each subrack of gathering to the fire control controller.
Therefore, through setting up a plurality of first temperature sensor and a plurality of second temperature sensor, can master the temperature of every lithium cell and the temperature of each subrack in time, the fire control controller can detect the too high lithium cell of temperature rise and the subrack that locates as early as possible to the accessible is to this subrack water injection to inside lithium cell cooling, is prevented taking precautions against the accident.

In this embodiment, for when detecting that thermal runaway appears, can open the water inlet of each subrack automatically, still set up automatically controlled valve respectively on each water inlet, and equally divide and do not be connected with the fire control controller.
When thermal runaway appears, the fire-fighting controller enables the water inlet to be opened by controlling the electric control valve, so that water is injected into the corresponding plug-in box through the water inlet, and heat generated by thermal runaway of a large number of lithium batteries is taken away by utilizing the heat absorption capacity of water.
On the basis of the structure of each embodiment, the following will describe the working process of the automatic fire-fighting energy storage cabinet for lithium batteries in detail.

Initially, the electric control valves at the water inlets of the plug boxes are all in a closed state, and the fire-fighting controller receives information collected by the first temperature sensors, the second temperature sensors and the smoke sensors in real time. Meanwhile, the fire-fighting controller has a self-checking function of the fire-fighting system, and performs self-checking on the whole system at regular time in a daily cycle, including checking of fire-fighting water pressure, an electric control valve at a water inlet, a smoke sensor, a first temperature sensor and a second temperature sensor, and the like. Once a fault occurs, the fire-fighting controller can send an alarm prompt to require operation and maintenance personnel to maintain so as to ensure the integrity of the fire-fighting system, and the fire-fighting system is online and available at any time.
When a lithium battery in a certain plug box rapidly rises and thermal runaway occurs, the temperature information of the collected lithium battery is transmitted to the fire-fighting controller by the first temperature sensor arranged on the upper end face of the lithium battery, the temperature information of the collected plug box is transmitted to the fire-fighting controller by the second temperature sensor arranged at the bottom of the plug box, and meanwhile, the collected smoke information is transmitted to the fire-fighting controller by the smoke sensor.
