Detailed description of the invention
In order to make technical scheme of the present invention and advantage more should be readily appreciated that, be described in further detail below in conjunction with accompanying drawing.Should illustrate, specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Use lithium battery on a large scale in current automobile, but be all generally offhand in lithium battery, in vehicle traveling process, detonation occurs, so we are for such problem, design a kind of fire extinguishing system.
A kind of fire extinguishing system, this fire extinguishing system is applied in automobile, current electric automobile very universal, but what provide electric energy for electric automobile is the battery pack be arranged in electric automobile, particularly lithium battery group.Because lithium battery is in an environment relatively closed, so, when lithium battery group has some batteries to go wrong time, easily cause detonation.So be arrange some sensors around lithium battery group in this fire extinguishing system, in the processor that the Signal transmissions to collected by sensor is attached thereto, a fire-extinguishing apparatus is arranged on battery pack side, and this fire-extinguishing apparatus is connected with processor, whether processor is compared according to the signal of sensor collection and battery pack normal operating condition signal and is judged, determine to use this fire-extinguishing apparatus to battery pack cooling fire extinguishing.
In the present invention, what sensor was arranged respectively is electrolyte sensor, Smoke Sensor and temperature sensor, and electrolyte sensor gathers the electrolytical situation in lithium battery group, is arranged in battery pack; Smoke Sensor is the situation of the smog gathered in current environment, be arranged on the top of battery pack, temperature sensor is the temperature gathering surrounding environment and battery pack, arrange on the battery pack, according to the related data gathered with upper sensor, Real-Time Monitoring battery pack, to ensure that battery pack works in the environment of safety and stability.
In the present invention, fire-extinguishing apparatus can be similar to current fire extinguisher, also can be other more senior fire-extinguishing apparatus, a control valve is provided with at the opening of these fire-extinguishing apparatus, control valve is the duty controlling fire-extinguishing apparatus, control valve is connected with processor, processor determines whether opening controlling valve according to comparison result, and then controls the duty of fire-extinguishing apparatus.So include microprocessor, memory cell and comparing unit in the middle of processor, memory cell is connected with sensor, be used for the normal operating parameters of storage battery group, comparing unit is connected with memory cell, the signal parameter that sensor collects by comparing unit and normal operating parameters contrast, then transfer in microprocessor by comparison result, microprocessor controls the duty of fire-extinguishing apparatus according to comparison result.
Because at present in car battery be that strip is placed in a casing successively, the Battery case that formation one of connecting between each battery is large, but between some little strip cell, have certain space, be provided with the pipe of some openings in each space.Concrete, these pipes are just similar with the drip irrigation system in current green house of vegetables, but what spray in pipe in the application is extinguish material.Like this, when some independently batteries occur abnormal, control fire-extinguishing apparatus and fill extinguish material in pipe, and spray from the opening of pipe, to this battery cooling extinguishing operation.
One warning device is connected with processor, and when the state of lithium battery group is not very stable time, processor can send alarm signal in advance, remind surrounding people, when the state rather unstable of battery pack time, then fire-extinguishing apparatus starts work, carries out cooling fire extinguishing to battery pack.In the present invention, warning device can be buzzer, also can be light alarming device, preferably buzzer, can send ear-piercing sound like this, reminds personnel around.
In this application, the processing module be provided with in processor, such as the data processing module etc. of the sensor data acquisition, the parameter of the real-time residing environment of lithium battery that these data processing modules collect according to sensor, then carries out computing.For in current conventional environment, security context parameter residing for battery pre-enters in processor, there is a reference value like this, then for this reference value, namely in environment residing for this battery pack, any one has independent reference value, after inputting these numerical value completely, each numerical value that sensor collects compares with reference value, after wherein any one exceedes warning value, warning system will work, and carries out pre-alarm work.Now also not to when fire-extinguishing apparatus work, because be also provided with a fire-extinguishing apparatus operating point within a processor, namely a warning value is provided with within a processor, because reference value is before as a prevention effect, inspection is done again late when the real catching fire of battery gets up time, so, preset one defence line, then, when in sensor, any one instantaneous value exceedes warning value time, this fire-extinguishing apparatus works.Whether the reference value preset can reminding user or staff check the battery in battery case in time, be maloperation, or some place exceeds normal range (NR) a little really, overhauls timely, avoids dangerous generation.And the warning value of setting operates under to be this battery case be in a more dangerous situation really timely.May not be sometimes that internal battery pack generates heat reason on fire, may be extraneous temperature or humidity etc. beyond scope, namely whole battery pack is normal, also can work like this carry out cooling protection work to battery pack for fire-extinguishing apparatus.Ensure that lithium battery group runs under the environment of a safety in real time.
Also data memory module is provided with in processor, above-mentioned various data are all stored, also have one in processor and optimize module, be optimized according to the data that these equipment produce, because battery pack has certain life-span, when battery pack is run under a unsound state, the data that sensor collects are to processor, and the optimization module in processor just can be modified to the reference value of artificial setting before and warning value.For such situation; can protect according within the scope of the certain ability to work of battery pack; when battery pack be in operate under later stage unsound state time; processor can be monitored battery pack according to the reference value of change and warning value, and optimization module ensure that the safety in battery pack long-term work situation.
In addition, a communication module is also provided with in fire extinguishing system of the present invention, this communication module is connected with processor, the Various types of data stored in the signal of sensor collection and memory module is sent on remote data capture equipment by this communication module, like this, the manufacturer of battery pack just can be regular to these data analysis and arrangement, draws more optimization data, battery pack and whole fire extinguishing system are upgraded, produces the product that yield is higher.
