Description
Technical field
The utility model relates to electrokinetic cell field, particularly a kind of inerting battery case.
Background technology
Pure electric vehicle or hybrid vehicle have wide future develop.Electrokinetic cell is applied to electric power, communication, the field such as mining gradually, has shown good social economic value.Electrokinetic cell is placed in the battery case of sealing conventionally.
In above-mentioned electrokinetic cell application, the safety problem of electrokinetic cell system is one of principal element affecting its large-scale application always.According to domestic and international relevant report, there is the accidents such as spontaneous combustion in multiple electric automobile in succession, even caused individually serious loss of life or personal injury.The factor that causes electric vehicle battery system spontaneous combustion or blast is roughly divided into following five kinds.
1) thermal runaway that the situations such as the internal short-circuit of battery that battery quality problem causes because of technological reason in battery production manufacture, leakage cause, thermal runaway diffuses to the burning that whole battery system causes.
2) battery system heat management lost efficacy, battery system planted agent, rational heat management system to be set, and controlled battery system temperature rise under high rate charge-discharge operating mode repeatedly.If above-mentioned heat management system lost efficacy, battery core internal temperature rise surpasses its safe range, and pressure increases and causes electrolyte to overflow to cause partial short-circuit, then accident expanded range.
3) battery system is installed fixedly design failure, causes battery system mobile generation in battery case to clash into, and causes cell fracture or damage under critical conditions, causes burning.
4) battery system internal connection line bundle, because of long term wear, causes insulation damages, causes short trouble.
5) motor vehicle is subject to outside strong shock, causes vehicle gross distortion to damage, and causes that the battery case distortion that is squeezed causes accident.
Analyze above-mentioned accident cause and process, battery system burning immediate cause is that the oxygen concentration in battery case is high, and in battery case, the local spontaneous combustion of appearance fails to eliminate in time, then causes accident expanded range, has caused serious consequence.
Utility model content
The purpose of this utility model is to provide a kind of inerting battery case that fills inert gas, and the possibility of burning occurs to reduce battery case.
To achieve these goals, the utility model adopts following technical scheme: inerting battery case, comprise the casing of battery being installed for sealing, and casing is provided with inert gas input port.
Casing is provided with for discharging the exhaust outlet of oxygen-containing gas.
Described inert gas input port and exhaust outlet are arranged at respectively the both ends of casing.
Described inert gas input port is positioned at the upper right side of casing, and exhaust outlet is positioned at the lower left of casing.
In casing, be provided with for detection of oxygen concentration in casing whether lower than the oxygen content detector of the setting combustion limits value of battery case.
On casing, be also provided with power interface for being connected with external loading and control interface for being connected with external control devices, power interface and control interface are waterproof sealing connector.
The beneficial effects of the utility model: can input inert gas in casing by inert gas input port, thereby can reduce the oxygen concentration in casing, when local spontaneous combustion or short circuit appear in battery, cannot form burning condition, thereby can reduce the probability that burning occurs battery case.
Further, when filling inert gas in battery case, by exhaust outlet, the oxygen-containing gas in casing can be discharged, reduce the oxygen concentration in casing.
Further, inert gas input port and exhaust outlet are arranged at respectively the both ends of casing, are convenient to oxygen-containing gas to discharge casing, are convenient to the oxygen concentration in fast reducing casing.
Further, inert gas input port is positioned at the upper right side of casing, and exhaust outlet is positioned at the lower left of casing, can be so that fast oxygen-containing gas be discharged to casing, and the concentration of the inert gas in casing is raise fast.
Further, whether oxygen content detector can be for detection of oxygen concentration in casing lower than the setting combustion limits value of battery case, in casing, input in inert gas process, oxygen content in casing is during lower than combustion limits value, can stop inputting inert gas in casing, now by inert gas input port and exhaust close; In the use procedure of battery case, by oxygen concentration in periodic testing battery case, can judge that whether the flame-retarding characteristic of battery case is effective, can judge that the sealing of battery case is enough good simultaneously.
Further, power interface and control interface are waterproof sealing connector, can effectively keep the sealing of battery case, avoid battery to be subject to the corrosion of extraneous smog air.
