Embodiment
Below in conjunction with Figure of description, be clearly and completely described the technical scheme in the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent.To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.
As shown in Figure 1, the invention provides a kind of charging control system of electric automobile, comprising: for providing the converter 1 of AC field, the storage battery 3 be electrically connected with this converter 1; And keep with this converter 1 and storage battery 3 adjuster 2 that is electrically connected respectively; The electric field that this adjuster 2 exports for controlling described converter 1; This adjuster 2 also keeps being electrically connected with pressure sensor 4, and this pressure sensor 4 is arranged on the inside of the storage battery 3 be electrically connected with this converter 1, for the pressure of the gas of generation in this storage battery 3 of perception; The electric field that this converter 1 of gas pressure signal controlling that described adjuster 2 detects based on this pressure sensor 4 exports.
Converter 1 and adjuster 2 are all the state of the art, any supply unit that output current can be provided to complete charging to storage battery can use as converter here, adjuster is also the output electric field controlling converter with the control mode of routine, mainly controls the output current of converter 1 in this application.The converter 1 of a type and adjuster 2 and storage battery 3 is simply show in Fig. 1, it is to be noted, the converter 1 related in figure and the internal structure of adjuster 2 and storage battery 3 are only schematic, concrete structure does not affect the understanding to the disclosure of invention completely, because converter 1 and adjuster 2 and storage battery 3 have a large amount of examples in the prior art, do not do too much description to the specification of its internal structure the application, those skilled in the art can obtain completely from prior art.
The transmission characteristic of this pressure sensor 4 is when the pressure gas produced in storage battery 3 being detected is zero, pressure sensor 4 feeds back open circuit signaling to adjuster 2, now adjuster 2 controls the output current of the electric field that converter 1 exports towards the direction adjustment increased, until the pressure that pressure sensor 4 detects is greater than zero, the output current of the electric field of now converter 1 output reaches lowest high-current value, and adjuster 2 controls the outputting current steadily of the electric field that converter 1 exports at this lowest high-current value.The application is found by a large amount of tests, when the pressure of the gas produced in storage battery 3 is zero, the charging current ability to accept of storage battery 3 is maximum, and now adopting large charging current to carry out charging greatly can improve charge efficiency, shortens the overall charging interval.Find in process of the test, the application is tested to the storage battery adopted, actual charging current should more than the lowest high-current value of 90 amperes.When charging current is higher than this lowest high-current value, the useful life of this storage battery obviously shortens.Experimental data shows, the application is tested to the storage battery adopted, and the charging current of 90 amperes is equivalent to the electric current that storage battery can accept substantially, interval near the electric current that can accept at storage battery in other words.Certainly, this lowest high-current value is relevant with capacity with the kind of storage battery, and the storage battery of different electric automobiles has different lowest high-current values.
Along with the carrying out of charging, the ability to accept of storage battery to charging current declines gradually, and that is, acceptable electric current declines gradually.Test data shows, when pressure sensor 4 detects that the pressure of the gas produced in storage battery is elevated to 0.07g/m
2(gram every square metre, lower same) time, show that the gas evolution rate of storage battery has increased obvious critical value, if now continue to adopt lowest high-current value to charge, this lowest high-current value is the obvious current capacity that can accept beyond storage battery, the direct result caused be exactly exceed ability to accept this one part of current in fact for the precipitation of supply gas, and then cause charge efficiency to reduce, find in process of the test, now storage battery has completed the charging capacity of about 90%, the time be filled with before but often required in the process of charging capacity the completing 90%-99% time is substantially equal to needed for 0-90% capacity, that is, this way wastes the charging interval and causes the low of charge efficiency.
In order to avoid the problems referred to above, when pressure sensor 4 detects that the pressure of the gas produced in storage battery is elevated to 0.07g/m
2time, the output current making adjuster 2 control the electric field that converter 1 exports regulates towards the direction reduced, until the electric current that converter 1 exports is reduced to the minimum current value of 16 amperes.When pressure sensor 4 detects that the pressure of the gas produced in storage battery is elevated to 0.11g/m
2the second predetermined value time, adjuster 2 controls the outputting current steadily of the electric field that converter 1 exports at the minimum current value of 16 amperes.In actual charging process, when pressure sensor 4 detects that the pressure of the gas produced in storage battery is in 0.07g/m
2and 0.11g/m
2between time, can freely specify any current value between the lowest high-current value of 90 amperes and the minimum current value of 16 amperes to complete quick charge as charging current.Such as at room temperature, adjuster can by charge current stabilizes at 51 amperes.
In a typical automation operating system, usually charge from zero air pressure of storage battery, as long as the air pressure that pressure sensor 4 detects is zero, just can increase charging current always, until the air pressure that pressure sensor 4 detects is greater than zero, now charging current reaches lowest high-current value.Adjuster 2 controls the outputting current steadily of the electric field that converter 1 exports at this lowest high-current value, until the air pressure that pressure sensor 4 detects reaches the first predetermined value.Now adjuster 2 controls the output current of the electric field that converter 1 exports towards the direction adjustment reduced, until the air pressure that pressure sensor 4 detects reaches the second predetermined value.Now charging current reaches minimum current value.Adjuster 2 controls the outputting current steadily of the electric field that converter 1 exports at this minimum current value, until storage battery completes charging, that is storage battery is full of.
Those skilled in the art can understand completely, and for different storage batterys, above-mentioned lowest high-current value, the first predetermined value, the second predetermined value and minimum current value can have different values.But according to content disclosed in the present application; those skilled in the art can determine the actual value of concrete lowest high-current value, the first predetermined value, the second predetermined value and minimum current value completely by identical test method; without the need to spending creative work; therefore the concrete selection of above-mentioned numerical value should not be considered as essential improvement of the present invention, within the protection range that is falling into the claim of the application.
Specific to an embodiment of the application, the exemplarily explanation of property, above-mentioned lowest high-current value is taken as 90 amperes, and the first predetermined value is taken as 0.07g/m
2, the second predetermined value is taken as 0.11g/m
2, minimum current value is taken as 16 amperes.
This pressure sensor 2 inside arranges multiple micropore, this micropore is for removing the change slowly of the pressure of the internal storage battery caused because of variations in temperature, atmospheric pressure or a small amount of gas of producing due to electrolyte or pole plate impurity, and this micropore makes this pressure sensor only detect the Rapid Variable Design of the gas pressure produced in battery charging process.
Carry out deep contrast to storage battery can find, the charge characteristic of storage battery is nonlinear often, expresses a storage battery impossible only not with an accurate electric current or magnitude of voltage.The characteristic of storage battery is very responsive to temperature and time, and the conventional state kept according to voltage and current is carried out charging and produce many contradiction in actual mechanical process.Relevant achievement in research has been had in prior art, the corresponding relation of the charging capacity of storage battery and voltage and temperature is made the form of curve chart by lot of experiments, indicate the charging voltage of various temperature and charge percentage, but this curve chart is the real instantaneous state representing storage battery just, and also can not repeat completely accurately with same battery or any one other similar battery.
As the further optimization of the above-described embodiment to the application, the application also immerses temperature sensor in the electrolyte of storage battery, detect that the temperature of electrolyte is equal to or greater than when 60 DEG C at this temperature sensor, by the minimum current value of the outputting current steadily of the electric field of this adjuster control converter output at 16 amperes.Found by a large amount of tests, when being equal to or greater than 60 DEG C, any current value being greater than 16 amperes all can cause the state of overcharging.The applicant of this respect the application did part test, but effect is unsatisfactory, predetermined curve is handy to a kind of storage battery in sometime, but but provides different data in another time, and may not be suitable for other storage battery completely.Therefore the application only proposes protection request to the concrete numerical value of 60 DEG C and 16 amperes, lists dependent claims in, need further research to other numerical value.
As further optimization, when pressure sensor 4 detects that the pressure of the gas produced in storage battery 3 is at 0.07g/m
2to 0.11g/m
2between, and time this temperature sensor detects that the temperature of electrolyte is less than 60 DEG C, this adjuster is controlled the outputting current steadily of the electric field that converter exports at intermediate current value.Although point out above, when pressure sensor 4 detects that the pressure of the gas produced in storage battery is in 0.07g/m
2and 0.11g/m
2between time, can freely specify any current value between the lowest high-current value of 90 amperes and the minimum current value of 16 amperes to complete quick charge as charging current.But many experimental results shows, current value is stabilized in a median and is conducive to improving charge efficiency, this intermediate current value is set to 51 amperes, the charging interval can be shortened significantly.
In sum, be embodiments of the invention content, and obviously embodiments of the present invention are not limited in this, it can according to different application environment, utilizes of the present inventionly functionally to realize corresponding demand.
