As shown in Fig. 1 of schematic diagram embodiment, described power circuit provides galvanic current source for current controller
For being charged accumulator, it can be other circuit with stable on MCU controller and intelligence quick charge device
Working power.
Preferably, MCU controller uses saturated large current charge when selecting reversion mise-a-la-masse method, reaches in accumulator charging
Saturated gasification point moment allows current controller reversion electric discharge to absorb the saturated excess gas produced immediately, and current controller is continuous
Circulate saturated large current charge and reversion electric discharge until accumulator is full of.Preferably, described reversion mise-a-la-masse method can fill with cumulative
Electrical method, in critical mise-a-la-masse method, decrescence mise-a-la-masse method, pulsation mise-a-la-masse method, certain one or more being combined uses, different to be suitable for
The needs of charging rate.Such as, when charging rate is selected in ultrafast speed gear, the quick cumulative electric current of cumulative mise-a-la-masse method is first used to fill
Electricity scheme makes accumulator reach saturated charged state, then uses reversion mise-a-la-masse method to charge to the 80% of accumulator electric-quantity, finally adopts
Complete accumulator is fully charged with decrescence mise-a-la-masse method, stagewise combine different charging modes and be applicable not only to reversion and fill
Electrical method, is also applied for critical mise-a-la-masse method, pulsation mise-a-la-masse method, cumulative mise-a-la-masse method.

Increase in electric current charging process be also classified into the charging of the most cumulative electric current, the charging of middling speed cumulative electric current, quick cumulative electric current charge this three
The scheme of kind.Current controller receives the cumulative current charging signal that MCU controller sends, and accumulator is stepped up charged electrical
Pressure strengthens charging current, until detect accumulator charging reach voltage when saturated air is sent out occur slightly decreasing phenomenon-Δ V
Change, charging voltage value or charging current value when saturated air is sent out by MCU controller all lower a point value as critical charging
Magnitude of voltage and critical charging current value, recharge for next step and all to lower as foundation, charging voltage value and charging current value
Mode time more is remote critical method, downward fewer time mode be near critical method, mode during downward minimum is
Critical method, cumulative mise-a-la-masse method can be used for the initial charge process of various mise-a-la-masse method.At the width increasing electric current in cumulative charging process
What the degree one timing used time was longer be the most cumulative charging, the used time moderate for the cumulative charging of middling speed, what the used time was shorter is quick the most gradually
Increasing charging, such as charging current automatically progressively increases to 5A from 1A, and 60 seconds used times were the most cumulative charging, and 40 seconds used times were middling speed
Cumulative charging, 20 seconds used times were quick cumulative charging.The cumulative principle of cumulative mise-a-la-masse method is also used in other mise-a-la-masse methods, such as
During the cumulative charging of employing batch (-type), often fill a period of time just interval and within several seconds, carry out detecting charging effect, be then further added by charging
Electric current, is the most so repeated cumulative charging；During charging cumulative for example with pulsating, first with pulsation trick charge, then
With pulsation low current charge, then use pulsation large current charge, and pulsation critical current charges, pulsation saturation current fills
Electricity, the most progressive cumulative charging；During charging cumulative for example with critical formula, remote critical current is first used to charge, then
Use the charging of near critical electric current, finally use critical current charging；During charging cumulative for example with reversion, first use the most saturated
Reversion charging, the then charging of employing middling speed saturated inversion, finally employing are rapidly saturated reversion charging.As these of cumulative mise-a-la-masse method
Multiple embodiments also has more application mode in this intelligence quick charge device.
Preferably, described reversion mise-a-la-masse method has saturated inversion charging at a slow speed, the charging of middling speed saturated inversion, is rapidly saturated
Reversion three kinds of schemes of charging, difference be size and the time of charging saturation current during reversion charging number, be to perform instead
Discharge current size when relaying electricity and the number of time.Such as, when certain accumulator carries out inverting mise-a-la-masse method, set
The saturated charging current of saturated inversion charging is 4A at a slow speed, and the saturated charging interval is 60 seconds, inverts discharge current 0.8A, and reversion is put
The electricity time is 12 seconds；The saturated charging current of set middling speed saturated inversion charging is 4.5A, and the saturated charging interval is 45 seconds,
Reversion discharge current 1.2A, reversion discharge time be 8 seconds；The set saturated charging current being rapidly saturated reversion charging is
5A, the saturated charging interval is 30 seconds, invert discharge current 1.6A, reversion discharge time be 5 seconds.To different accumulator owing to holding
Amount difference, kind is different, when the charging interval requires difference, set saturation current full charge time and discharge current electric discharge
Between the most different, the preferred charge data mainly crossed with laboratory proofing is set.
Preferably, described critical mise-a-la-masse method is to carry out accumulator quickly by critical charging voltage or critical charging current
Charging process, its critical aspects is also classified into remote critical method, near critical method, critical method three kinds, during this charging voltage or
Electric current, all close to peak value, i.e. ensure that accumulator charging safety makes again the charging interval reach quickly and is worth.Such as fill in certain accumulator
Saturation current when electricity is saturated is 5A, and the charging of remote critical method selects 4A to charge, and near critical method selects 4.3A to charge, and critical method selects 4.7A
Charging.Such as the saturation voltage when the charging of certain mobile phone accumulation pond is saturated is 9.5V, and the charging of remote critical method selects 8.5V to charge, closely
Critical method selects 8.8V to charge, and critical method selects 9.1V to charge.Different due to capacity to different accumulator, kind is different, to charging
Time requirement is different, and set remote critical method, near critical method, the charging current of critical method and charging voltage are the most different,
The preferred charge data mainly crossed with laboratory proofing is set.When charging with critical mise-a-la-masse method, accurate pressure sensor is all the time
Detection charging saturated time-Δ V decline change occur, under when occurring, MCU controller is charged voltage or charging current
Mediate reason so that till critical charging lasts till that accumulator electric-quantity is full of.
Preferably, described decrescence mise-a-la-masse method is to use constant voltage or constant-current charge and gradually decrease voltage or current value to storage
Battery carries out safe charging, until accumulator electric-quantity be full of process, decrescence charging process is divided into the most decrescence charging,
Middling speed is decrescence charged, these three scheme of the most decrescence charging.Decrescence in the amplitude one timing used time reducing electric current in charging process
Longer for the most decrescence to charge, used time moderate decrescence charging for middling speed, the used time shorter for quickly decrescence to charge, such as fill
Electricity electric current automatically tapers to 1A from 5A, and 60 seconds used times, 40 seconds used times decrescence charged for middling speed in order the most decrescence to charge, 20 seconds used times
For quickly decrescence charging.During decrescence mise-a-la-masse method can be used for the later stage charging process of various mise-a-la-masse method.Decrescence mise-a-la-masse method is the most former
Reason is also used in other mise-a-la-masse methods or temperature anomaly processing scheme, and such as certain accumulator tail later stage decrescence charging process is followed successively by
1A constant current charge, 0.8A constant current charge, 0.6A, 0.4A, 0.2A, 0.1A, 0. 05A constant current decrescence charge, until electric power storage
Till pond is full of.Such as mobile phone later stage constant voltage decrescence charging process is followed successively by the charging of 5V constant voltage, 4.8V constant voltage charges,
4.6V, 4.4V, 4.2V, 4.0V, 3. 9V constant voltage decrescence charge, until accumulator is full of.Decrescence mise-a-la-masse method has a variety of
Implementation, when charging for example with decrescence batch (-type), often fills a period of time just interval and within several seconds, carries out detecting charging effect, so
After reduce charging current again, be the most so repeated and decrescence charge；When charging for example with decrescence pulsing, first saturated with pulsation
Electric current charges, then with pulsation large current charge, then uses pulsation low current charge, and pulsation trick charge, so connect
Continuous progressive decrescence charging；When charging for example with the most critical formula, first use critical current charging, then use near critical electricity
Current charge, finally uses remote critical current to charge；During for example with reversion charging, first use to be rapidly saturated inverting and charge, then
Use the charging of middling speed saturated inversion, finally use saturated inversion at a slow speed to charge.These multiple embodiments as decrescence mise-a-la-masse method
