Said temperature compensation coefficient adjusting module, its temperature signal input links to each other with the temperature signal output of said temperature sensor, and its signal output part is connected with said voltage regulator module;
Said voltage regulator module, its control signal output ends is connected with the voltage control signal input of said charger;
Said temperature sensor is arranged on the said charger, monitors the ambient temperature of charger in real time.
The operation principle of full-automatic intelligent charger according to the invention is following:
Charger is when beginning to charge, and said Fuzzy control system charges to storage battery by the charge parameter of having stored in it.
Charger is in charging process, and said collector is gathered charging voltage and the electric current of charger in charging process in real time; Then, give said calculus computing module with the voltage and current transfer of data; Said calculus computing module is made up of differential calculation module and integral and calculating module; Said calculus computing module and integral and calculating are received from the voltage and current signal of said collector input respectively; And above-mentioned voltage carried out differential calculation, the variation tendency of voltage when drawing charging; Current signal is carried out integral and calculating to the time, draw the electric weight that current storage battery has charged.At this moment, the electric weight of the storage battery of the said calculus computing module input of the real-time reception of said fuzzy control model, and in real time this electric weight and the capability value stored in it are compared; When two values were identical, said fuzzy control model can judge whether storage battery is full of according to the charging voltage variation tendency, when being downward trend as if the charging voltage variation tendency; The control command that output immediately stops to charge; If not the control command of output resume charging is accomplished until charging.At this moment, said fuzzy control model can draw the battery capacity identification error, and the charge parameter that upgrades in time and stored.When recharging, fuzzy control model can charge to battery by the charge parameter of this storage next time.
In addition, the present invention also is provided with temperature sensor, temperature compensation coefficient adjusting module and voltage regulator module.Its reason is: the float charge voltage value that the explanation that existing storage battery producer is provided provides is meant that all ambient temperature is 25 ℃ a value.When temperature was higher than 25 ℃, accumulator internal resistance reduced, and floating current increases, the corrosion aggravation of the conducting element in the storage battery, thereby the life-span of having reduced storage battery; When temperature was lower than 25 ℃, the internal resistance of storage battery increased, and can not effectively release energy to load, so the float charge voltage of varying environment temperature should be adjusted by certain temperature compensation coefficient.When temperature was high, float charge voltage should be lower than standard value; When temperature was hanged down, float charge voltage should be higher than standard value.The adjusting formula of the float charge voltage of cell is shown below:
The U=U mark+(25-t) * (t ')
In the formula, U is the float charge voltage set point; U is designated as the float charge voltage standard value; T is an ambient temperature, and t ' is a temperature compensation coefficient, and this coefficient can rule of thumb be worth acquisition.
After temperature sensor according to the invention detects ambient temperature; This temperature signal is transferred to said temperature compensation coefficient adjusting module; Said temperature compensation coefficient adjusting module is according to the height output temperature penalty coefficient of temperature; After said voltage regulator module receives the temperature compensation coefficient of said temperature compensation coefficient adjusting module input, by above-mentioned principle, output charging voltage adjustment control signal; Said charger is by the control signal adjustment charging voltage of said voltage regulator module output.
Fuzzy control model is based on fuzzy control technology described in the present invention, and fuzzy control technology is based on fuzzy mathematics theory, through anthropomorphic dummy's approximate resoning and integrated decision-making process, controllability, adaptability and the reasonability of control algolithm is improved.The principle of fuzzy control of the present invention is: when battery begins to charge; Fuzzy control model is promptly exported a charging control signal, and charger promptly charges by this control command, when charger charges by this control command; The voltage that detect the battery two ends this moment does not also reach battery and is full of magnitude of voltage when above; The signal of detection system output this moment battery capacity identification error, fuzzy control model is exported a charging control signal once more, continues to charge the battery; When the voltage at battery two ends rises to when being full of magnitude of voltage; Fuzzy control model can be changed the relevant charge parameter of its stored automatically, and through change several times, Fuzzy control system just can be discerned the D.C. capacity of the battery of current use.If charging next time, battery changes, and Fuzzy control system just experiences the process of such learning and memory again.
For example, electric car charger, the general charger battery that only charges; Charging is for the first time charged by the battery parameter (corresponding electric current and voltage) of 10AH, is not full of voltage 14V when above if also arrive during charging 10AH energy near battery, representes the battery capacity identification error; If it is too big that recognized capability differs; It is very little to detect the cell voltage rising, rises to more than the 14V the relevant charge parameter of change immediately up to cell voltage; Like this through just discerning the D.C. capacity of the battery of current use, the line correlation of going forward side by side memory after twice charging cycle.
More than; Be merely preferred embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical staff who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range that claim was defined.
