Abstract
The utility model relates to a battery energy storage system security domain especially relates to power battery security domain. A fire -retardant device of battery energy storage system, the oxygen concentration of in with the battery box reduces to certain degree, avoids battery burn violently in the battery box to group battery thermal runaway chain reaction's a key ring has been nipped off, delay that can great degree and avoid thermal runaway chain reaction, when having produced combustible gas in the battery box, can pass through relief valve and exhaust duct, with the combustible gas safe region outside the battery box that discharges, orderly burning can bigger degree and the control batteries group thermal runaway reaction of longer time, reduces its extent of injury.
Description
Technical field
The utility model relates to battery energy storage system security fields, particularly relates to electrokinetic cell security fields.
Background technology
Under the trend of global new forms of energy revolution fast development, the industries such as photovoltaic, wind-powered electricity generation, electric automobile are all competitively being developed in countries in the world, and one of its core technology is energy-storage system, especially battery energy storage system.But under existing battery technology condition, battery can produce amount of heat in the course of work of charging and discharging, also may burn and explode overcharging, in the situation such as overheated and short circuit.As the battery pack of energy-storage system, battery is together intensive, and in use procedure, heat is easily accumulated, and cells burst explosion time occurs and easily causes chain reaction.Battery energy storage system is the object of energy-intensive, and the energy that burning and explosion time release occur is huge, and harmfulness is also very big.Safety is the necessary basis condition of new forms of energy development, and the safety management of battery energy storage system is a core technology in current new forms of energy revolution.
Solve the safety problem of current battery energy-storage system, mainly will solve the thermal runaway problem of battery pack, especially cause the cells burst problem of thermal runaway chain reaction.
Solve the cells burst problem causing thermal runaway chain reaction, fire-retardant is best bet.One of necessary condition of burning is oxygen, and when the Packing Sound of battery core, battery can not vigorous combustion, and when the breakage of packing of battery core, the air in Battery case enters battery core, and vigorous combustion occurs.If there is no air in Battery case, or there is no oxygen in Battery case, would not vigorous combustion when battery core is broken.
Utility model content
For solving the safety problem of current battery energy-storage system, the utility model proposes a kind of battery energy storage system fire-retarding device, stoping battery vigorous combustion, at utmost stop thermal runaway chain reaction.
The utility model solves the technical scheme that its technical problem adopts:
A kind of battery energy storage system fire-retarding device, comprises battery case, inflation inlet, exhaust outlet, relief valve and discharge duct.Battery case is the casing of sealing, battery tank wall is provided with inflation inlet, exhaust outlet and relief valve, and inflation inlet and exhaust outlet are symmetrical on battery tank wall to be installed, and keeps maximum distance as far as possible.Inflation inlet and exhaust outlet are provided with valve.The end of inflation inlet is provided with flow-stopping plate, presses close to the flowing of battery case inwall for guiding air-flow.Discharge duct is arranged on battery case outside, and one end of discharge duct is connected with relief valve, and the other end extends to safety zone.Pressure sensor and oxygen concentration monitor are also installed in battery case, the gaseous state in battery case can be fed back to battery management system in time.In battery case, oxidizable material bag is also installed, is used for catching oxygen remaining in battery case and the oxygen infiltrated in battery case that accumulates over a long period.
The process realizing the first method that the oxygen concentration in battery case is declined is, in battery case, inert gas is filled by inflation inlet, air in battery case is discharged from exhaust outlet, detect the oxygen concentration of exhaust outlet, when the oxygen concentration that exhaust outlet is discharged is stable reach desired value time, close exhaust outlet and inflation inlet.The process realizing the second method that the oxygen concentration in battery case is declined is connected with inert gas storehouse by the inflation inlet of battery case, the oxygen in exhaust outlet fuel cell case, after combustion reaction stops, closing exhaust outlet and inflation inlet.The process realizing the third method that the oxygen concentration in battery case is declined is, exhaust outlet is connected with vacuum pump, starts vacuum pump, the air in battery case is extracted into vacuum to a certain degree, then in battery case, fill inert gas by inflation inlet, then close exhaust outlet and inflation inlet.
The process realizing the safety zone be discharged to outside battery case by fuel gas is, when battery core breakage of packing or explosion time occur in battery case, the fuel gas produced makes the air pressure in battery case increase, when pressure reaches certain value, relief valve is opened, gas is discharged to discharge duct, and relief valve cuts out subsequently.Fuel gas, by discharge duct, discharged to safety zone, contacts with air, burns in order.
Inert gas described in the utility model can also replace with other fire-retardant gas.
The beneficial effects of the utility model are, oxygen concentration in battery case is reduced to certain degree by this technical scheme, avoid battery vigorous combustion in battery case, thus nipped off key one ring of battery pack thermal runaway chain reaction, can postpone largely and avoid thermal runaway chain reaction; This technical scheme is when creating fuel gas in battery case, by relief valve and discharge duct, fuel gas is discharged to the safety zone outside battery case, burns in order, can react with the control battery pack thermal runaway of longer time more, reduce its extent of injury.
