Background
The problem of mismatching of space-time distribution between a power source and a load in new energy power generation in recent years influences the stability of a power system. With the increasing maturity of power electronic technology and battery technology, energy storage becomes an excellent solution to this problem.
The existing energy storage scheme is mainly based on lithium batteries, and compared with other energy storage modes, the energy storage device has the advantages of high energy density, long cycle life, high efficiency and the like. However, due to the characteristics that the spontaneous combustion risk of the lithium battery is high and the batteries in the box body of the energy storage system are densely stacked, the high fire safety is a vital technical requirement of the battery energy storage system; meanwhile, the charging and discharging of the lithium battery need to be operated within a proper temperature range, otherwise, the service life of the battery is seriously influenced, and even thermal runaway is caused. Therefore, the battery pack in the battery energy storage system needs a cold and hot air pipeline for temperature control and a pipeline for spraying a fire extinguishing medium.
However, it is difficult to accommodate multiple pipes in the limited three-dimensional space inside the battery energy storage system, otherwise a large amount of extra space is consumed, and the system volume is increased. Therefore, how to save the inner space of the precious battery energy storage system and simplify the pipeline becomes the problem that the battery energy storage system needs to be solved urgently.

Preferably, the mode selection valve is two electromagnetic valves, the two electromagnetic valves are respectively arranged on a manifold connected with the temperature control subsystem and the fire protection subsystem, and the two electromagnetic valves are connected with a control system of the energy storage system and controlled by the control system of the energy storage system.
Preferably, the mode selection valve is a check valve, and the check valve is arranged on a manifold connected with the temperature control subsystem.

The invention has the beneficial effects that:
in order to meet the technical requirements of temperature control and fire safety of the battery energy storage system, corresponding cold and hot air pipelines and fire-fighting and fire-extinguishing medium pipelines need to be respectively deployed in a box body of the battery energy storage system, but in the space and the limited battery energy storage system box body, the size of the box body is greatly increased by the deployment of double pipelines. In order to save the inner space of the precious battery energy storage system and simplify the pipeline structure, the invention skillfully utilizes the characteristic that a cold and hot air pipeline and a nozzle controlled by the internal environment temperature are also the best outlets for spraying fire extinguishing medium to the battery pack in the energy storage system, and a mode switching valve is used for sharing the same pipeline and nozzle.
Meanwhile, the invention provides two control modes of the mode selection valve, wherein one mode selection valve control mode also utilizes the characteristic that the running pipe pressure of fire-fighting fire-extinguishing medium is far greater than the cold and hot air pipe pressure of the temperature control subsystem, adopts a simple and convenient low-cost manifold check valve, and avoids adopting an expensive and heavy program control valve switching device such as an electromagnetic valve to switch the use mode of the pipeline.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1, the invention is a multi-purpose pipeline structure of a battery energy storage system, the multi-purpose pipeline is installed in a box body 1 of the battery energy storage system, one end of the multi-purpose pipeline is respectively connected with a temperature control subsystem 3 and a fire protection subsystem 4 of the battery energy storage system through two manifolds 2, the other end of the multi-purpose pipeline is provided with a plurality of branch pipelines 5, and the branch pipelines 5 are provided with a plurality of nozzles 6 capable of spraying to the arrangement positions of stacked battery packs; the multipurpose pipeline is also provided with a mode selection valve, and the multipurpose pipeline can be occupied by the temperature control subsystem 3 or the fire protection subsystem 4 through the mode selection valve.
The temperature control subsystem 3 is used for injecting air or other gases with lower or higher temperature than the inside of the energy storage box body into one end of the multipurpose pipeline so as to maintain the normal working environment temperature of the battery pack. The fire fighting subsystem 4 is intended to feed a pressurized extinguishing medium in liquid or gaseous form to one end of the multi-purpose pipeline. It should be noted that the temperature control subsystem 3 and the fire protection subsystem 4 of the battery energy storage system, as well as the stacked battery pack, are all in the prior art. In addition, a plurality of sets of the multipurpose pipelines can be installed in the box body 1 of the battery energy storage system, and the nozzles 6 of the multipurpose pipelines are respectively aligned to the battery packs at different positions in the energy storage system.
The multipurpose pipeline provides the following two control modes of the mode selection valve:
control mode one
As shown in fig. 2, the mode selection valve is two solenoid valves 7, the two solenoid valves 7 are respectively disposed on the manifold 2 connected to the temperature control subsystem 3 and the fire protection subsystem 4, and the two solenoid valves 7 are connected to and controlled by the control system of the energy storage system.
When the temperature control subsystem 3 is required to inject air or other gas with lower or higher temperature than the inside of the energy storage box into one end of the multipurpose pipeline so as to maintain the normal working environment temperature of the battery pack, the control system of the energy storage system controls the electromagnetic valve 7 on the manifold 2 connected with the fire protection subsystem 4 to be closed, and simultaneously controls the electromagnetic valve 7 on the manifold 2 connected with the temperature control subsystem 3 to be opened. When the fire fighting subsystem 4 is required to inject liquid or gaseous pressurized fire extinguishing medium into one end of the multipurpose pipeline, the control system of the energy storage system controls the electromagnetic valve 7 on the manifold 2 connected with the fire fighting subsystem 4 to be opened, and controls the electromagnetic valve 7 on the manifold 2 connected with the temperature control subsystem 3 to be closed.
Control mode two
To further simplify the overall piping system, the mode selection valve is designed as a check valve 8, the check valve 8 being provided on the manifold 2 connected to the temperature control subsystem 3, since the use of a programmable valve such as a solenoid valve 7 is expensive and heavy.
Under this kind of control mode, when the fire control subsystem 4 took this multipurpose pipeline, because the pipe pressure of the liquid or gaseous fire-extinguishing medium through the pipeline is greater than cold and hot control by temperature change gas manifold 2 far away, consequently, the automatic pressure-bearing of the one-way check valve 8 that corresponds manifold 2 is closed, and the fire-extinguishing medium can not get into control by temperature change subsystem 3. The check valve 8 is not required to be arranged in the manifold 2 of the fire fighting subsystem 4, and when the temperature control subsystem 3 occupies the multipurpose pipeline, cold and hot temperature control gas can not cause any harm when entering the manifold 2 of the fire fighting subsystem 4.
In order to further ensure the sealing performance of the check valve 8, an inner ring step-shaped sealing ring 9 is arranged at the sealing part of a valve plate of the check valve 8 and the manifold 2.
