(3) work as V MIN≤ V BAT<V MAXThe time, start constant current charge.
(4) work as V BAT〉=V MAXThe time, start constant voltage charge, charging current I BATTo reduce gradually, be reduced to I FULLThe time charging circuit automatic disconnection, prevent to overcharge battery caused damage, and realize the purpose of energy savings according to this.
Fig. 4 is a User Defined charging interval model program flow chart of the present invention, and charger of the present invention can be operated under two kinds of patterns: User Defined charging interval charge mode and system default charge mode.
(1) if the user does not set the charging interval, then charger according to the charging flow of system default and rate of charge to battery charge, and the user can set the charging interval at any time under this pattern, and after this charger then can be operated under the User Defined charging interval pattern;
(2) after the user sets the charging interval, system goes out suitable rate of charge by the time value set in conjunction with the dynamic battery calculation of parameter of current collection, adjusts battery charging mode according to user then and realizes charging to battery.
Fig. 5 is battery capacity, voltage and temperature relation schematic diagram, this graph of a relation is stored in the chip of charger with the form of numerical tabular, the charger master controller obtains the open circuit voltage (OCV) and the Current Temperatures of battery respectively by voltage detection module and temperature detecting module, obtain the battery capacity information match therewith then by tabling look-up, the parameters of setting in conjunction with the user such as time can calculate information needed.
The relation of battery capacity, voltage and temperature method is by experiment determined: (sample size is many more as the sample body to get a certain size battery, precision then can be high more as a result), under different temperature, selected battery is carried out repeated charge, record the capacity of every battery and voltage, temperature relation curve, can obtain capacity, voltage, the temperature relation curve of such battery then by mean value.User to different display precisions requirements, can suitably regulate test point density (such as precision can select battery capacity 1%, 5% or 10% etc.), the temperature interval value also needs to divide according to different required precisions, has only provided T1 in the schematic diagram, the data under the T2 temperature.
Fig. 6 is rate of charge calculation process under the User Defined charging interval pattern of the present invention.The method step that calculates suitable rate of charge according to the charging interval of setting is as follows:
(1) the real account constant volume of counting cell at first;
The detection method of battery actual capacity is: after system inserts battery, at first, whether test current voltage is the nominal voltage value, if then write down this magnitude of voltage, if not the nominal voltage value is carried out charge or discharge to battery and (if the battery that inserts has charged finished, then measuring capacity need calculate by discharging), and continue monitoring battery voltage up to a nominal voltage value, and establishing this magnitude of voltage is V1, this is t1 constantly.Same method finds second voltage calibration point V2, is t2 constantly, the battery capacity percentage P1 when drawing cell voltage by tabling look-up and being V1, the volume percent P2 when cell voltage is V2.The charge/discharge electric weight C of this section period BdBe the electric current of this section period and the product of time, then the actual capacity of battery is:
C=C bd/(P2-P1)
Wherein:
When battery is in preliminary filling or constant current charging mode:
C Bd=I*t=I* (t2-t1) I is a charging current
When battery is in the constant voltage charge pattern:
C bd = ∫ 0 t f ( t ) Idt = ∫ t 1 t 2 f ( t ) Idt F (t) is a charging coefficient
(2) calculate the electric weight Ce of current battery storage then;
The computational methods of Ce are: whether the charging beginning back current voltage of test earlier is the nominal voltage value, if then write down this magnitude of voltage, if not the nominal voltage value, battery is charged, and continue monitoring battery voltage up to a nominal voltage value, establishing this magnitude of voltage is V1, constantly t1.Same method finds second voltage calibration point V2, t2 constantly, the battery capacity percentage P1 when drawing cell voltage by tabling look-up and being V1, the volume percent P2 when cell voltage is V2.The charge/discharge electric weight C of this section period BdBe the electric current of this section period and the product of time, then the current capacity of battery is:
Ce=C bd*P1/(P2-P1)
Wherein: when battery is in preliminary filling or constant current charging mode:
C Bd=I*t=I* (t2-t1) I is a charging current
When battery is in the constant voltage charge pattern:
C bd = ∫ 0 t f ( t ) Idt = ∫ t 1 t 2 f ( t ) Idt F (t) is a charging coefficient
Trickle preliminary filling stage and constant current charge stage current value are constant, charge into electric weight C BdCalculate very conveniently, be the product of charging current I and charging interval t.In the constant voltage charge stage, battery current reduces gradually along with the lengthening in charging interval, estimate the method for charging capacity more accurately, can adopt integral way, from begin to be charged to complete charge during this period of time between in, current value on each time point gets up to time integral, can obtain charging capacity very accurately.So the charging capacity of stage battery can be calculated according to following formula:
C 3 = ∫ 0 t 3 f ( t ) Idt
In the formula:, f (t) is a charging coefficient, t3 is the charging interval.
This kind method requires hardware system to have integrating function, and in order to simplify the hardware designs of charger, charger also can dispense integrating circuit, adopts discrete mathematical computations mode to estimate charge capacity, so following formula can be designated as:
C 3 = Σ 0 n ( I * Δt )
In the formula: I is the charging transient current, and Δ t is the sampling interval, and n is a sampling number, and the big more then estimated value of hits precision is high more.
So charging into the electric weight of battery can be expressed as:
C ch = I 1 * t 1 + I 2 * t 2 + ∫ 0 t 3 f ( t ) Idt
Or: C ch = I 1 * t 1 + I 2 * t 2 + Σ 0 n ( I * Δt )
(3) calculate the electric weight that the needs of preliminary filling stage, constant-current phase, constant-voltage phase charge into respectively according to the real account constant volume:
The battery peak capacity percentage of the preliminary filling stage that the system of setting up departments is set, constant-current phase, constant-voltage phase correspondence is respectively P YC, P HL, P HY, each charging stage, the required electric weight that charges into was respectively: C1, C2, C3, and the volume percent of charging beginning battery is P, the actual capacity of battery is C, then
If P≤P YC, then:
C1=C*(P YC-P)
C2=C*(P HL-P YC)
C3=C*(P HY-P HL)
If P YC<P≤P HL, then:
C1=0
C2=C*(P HL-P)
C3=C*(P HY-P HL)
If P HL<P≤P HY, then:
C1=0
C2=0
C3=C*(P HY-P)
(4) calculate definite rate of charge at last
If the charging interval that the user sets is T, the charging interval that the three phases trickle preliminary filling stage of battery charging process, constant-current phase, constant-voltage phase need is respectively t1, t2, and t3, then:
T=t1+t2+t3
Wherein:
T1=C1/I1 (C1: the electric weight that the trickle preliminary filling stage will charge into, I1: trickle-charge current, getting I1 is the electric current of a fixing little electric current or I2*1%, this value needs less than maximum preliminary filling electric current I Yc);
T2=C2/I2 (C2: the electric weight that constant-current phase will charge into, I2: the constant current charge electric current, should be smaller or equal to the maximum I of cell safety constant current charge electric current MAX);
T3=C3/I3 (C3: the electric weight that constant-voltage phase will charge into, I3: the constant voltage charge average current).
Then can draw constant current charge times electric current I 2:
I2=C2/(T-C1/I1-C3/I3)
Trickle preliminary filling stage and constant current charge stage current value are constant, and the charging interval equals charge capacity C divided by charging current I.But in the constant voltage charge stage, battery current reduces gradually along with the lengthening in charging interval, and charging process satisfies following condition:
C 3 = ∫ 0 t 3 f ( t ) Idt = F ( t ) I | 0 t 3
dF(t)=f(t)dt
Can calculate constant-voltage phase charging interval t3 by following formula, and calculate the battery charge in each stage thus, the charging current that design is calculated is I CH, maximum charging safe current is I MAX:
If I CH≤ I MAX, then getting the constant current charge electric current is I CH
If I CH>I MAX, then getting the constant current charge electric current is I MAX
The above only is the specific embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
