In step 1, by main power source device 20 and the 1st, the 2nd, the 3rd auxiliary power device 30,40,50 of charging device 10, carry out the charging of secondary cell 12.; the current control circuit 22 of main power source device 20 carries out work and with certain electric current, secondary cell 12 is charged; and the current control circuit 32,42,52 of the 1st, the 2nd, the 3rd auxiliary power device 30,40,50 carries out work and with certain electric current, secondary cell 12 is charged.In other words, as shown in the figure of Fig. 5, at time point t1, by 4 supply units 20～50, started secondary cell 12 to charge.Because charged by 20～50 pairs of secondary cells 12 of 4 supply units, can carry out rapid charge.By this charging, the voltage of secondary cell 12 progressively rises along with the process of time.
In step 2, whether the voltage of the secondary cell 12 in charging has been arrived to setting voltage Ve and judged.If "No" is returned to step 2; Till the voltage arrival Ve of secondary cell 12, repeatedly perform step 2 processing.The voltage of secondary cell 12 becomes after Ve, from the battery monitor circuit 53 output H level signals of the 3rd auxiliary power device 50; If be judged as YES "Yes" in step 2, enter step 3.
In step 3, the H level signal that controller 54 is exported according to battery monitor circuit 53 stops the action of current control circuit 52, so that the charging of the 3rd auxiliary power device 50 stops (the time point t2 of Fig. 5).In addition, the H level signal that latch circuit 55 can be exported battery monitor circuit 53 keeps predetermined time.
By stopping of the action of current control circuit 52, the electric current charging to secondary cell 12 reduces, and its result is, the voltage of secondary cell 12 exists internal resistance and causes it temporarily lower than the possibility of setting voltage Ve.But, because latch circuit 55 can keep predetermined time by H level signal, so controller 54 can not make current control circuit 52 move.Accordingly, can prevent that the vibrational state that repeatedly alternatively charges and stop and charging and start from appearring in the 3rd auxiliary power device 50.That is, the 3rd auxiliary power device 50 can be stable state.
In step 4, by main power source device 20 and the 1st, the 2nd auxiliary power device 30,40, continue secondary cell 12 to charge.
In step 5, whether the voltage of the secondary cell 12 in charging has been arrived to setting voltage Vd and judged.If "No" is returned to step 5; Till becoming Vd to the voltage of secondary cell 12, repeatedly perform step 5 processing.The voltage of secondary cell 12 becomes after Vd, from the battery monitor circuit 43 output H level signals of the 2nd auxiliary power device 40; If be judged as YES "Yes" in step 5, enter step 6.
In step 6, the H level signal that controller 44 is exported according to battery monitor circuit 43 stops the action of current control circuit 42, so that the charging of the 2nd auxiliary power device 40 stops (the time point t3 of Fig. 5).In addition, the H level signal that latch circuit 45 can be exported battery monitor circuit 43 keeps predetermined time.
By stopping of the action of current control circuit 42, the electric current charging to secondary cell 12 reduces, and with similarly above-mentioned, the voltage of secondary cell 12 exists internal resistance and causes it temporarily lower than setting voltage Vd possibility.But, because latch circuit 45 can keep H level signal predetermined time, so controller 44 can not make current control circuit 42 move (work).Accordingly, can prevent that the vibrational state that repeatedly alternatively charges and stop and charging and start from appearring in the 2nd auxiliary power device 40.That is, the 2nd auxiliary power device 40 can be stable state.
In step 7, by main power source device 20 and the 1st auxiliary power device 30, continued secondary cell 12 to charge.
In step 8, whether the voltage of the secondary cell 12 in charging has been arrived to setting voltage Vc and judged.If "No" is returned to step 8; Till becoming Vc to the voltage of secondary cell 12, repeatedly perform step 8 processing.The voltage of secondary cell 12 becomes after Vc, from the battery monitor circuit 33 output H level signals of the 1st auxiliary power device 30; "Yes" if the judgment is Yes in step 8, enters step 9.
In step 9, the H level signal that controller 34 is exported according to battery monitor circuit 33 stops the action of current control circuit 32, so that the charging of the 1st auxiliary power device 30 stops (the time point t4 of Fig. 5).In addition, the H level signal that latch circuit 35 can be exported battery monitor circuit 33 keeps predetermined time.
By stopping of the action of current control circuit 32, the electric current charging to secondary cell 12 reduces, and with similarly above-mentioned, the voltage of secondary cell 12 exists internal resistance and causes it temporarily lower than the possibility of setting voltage Vc.But, because latch circuit 35 can keep predetermined time by H level signal, so controller 34 can not make current control circuit 32 carry out work (action).Accordingly, can prevent that the vibrational state that repeatedly alternatively charges and stop and charging and start from appearring in the 1st auxiliary power device 30.That is, the 1st auxiliary power device 3 can be stable state.
In step 10, only by main power source device 20, continued secondary cell 12 to charge.
In step 11, whether the voltage of the secondary cell 12 in charging has been arrived to setting voltage Vb and judged."No", returns to step 11 if; Till becoming Vb to the voltage of secondary cell 12, repeatedly perform step 11 processing.The voltage of secondary cell 12 becomes after Vb, from the battery monitor circuit 23 output H level signals of main power source device 20; "Yes" if the judgment is Yes in step 11, enters step 12.
In step 12, controller 24 stops the action of current control circuit 22, makes the action of voltage control circuit 21 start (the time point t5 of Fig. 5) simultaneously.
In addition, the latch circuit 25 of main power source device 20 is when action switches to voltage control circuit 21 from current control circuit 22, can will keep predetermined time from the H level signal of comparator 27 outputs, accordingly, can prevent that action switches to current control circuit 22 from voltage control circuit 21 again in this predetermined time period.Like this, voltage control circuit 21 and current control circuit 22 can be stable state.
In step 13, whether the voltage of the secondary cell 12 in charging has been arrived to setting voltage Va and judged."No", returns to step 13 if; Till becoming Va to the voltage of secondary cell 12, repeatedly perform step 13 processing.When the processing action of carrying out this step 13, can make the charging current of the secondary cell 12 based on voltage control circuit 21 reduce as shown in the figure G1 of Fig. 5, like this, just can carry out high-precision charging to secondary cell 12, so that it arrives fully charged state.In addition, because auxiliary power device 30～50 only for setting the setting voltage Vc～Ve lower than the setting voltage Vb of main power source device 20, so auxiliary power device 30～50 is that the structure of charging device 10 is comparatively simple.
In charging, the voltage of secondary cell 12 is become after setting voltage Va, be judged as YES "Yes" in step 13, controller 24 stops the action of voltage control circuit 21.
Like this, by the action of the current control circuit 52～22 of each supply unit 50～20 being stopped at each time point t2～t5, can prevent that vibrational state from appearring in each supply unit 50～20, and then can prevent mutual interference and cause each supply unit 50～20 to occur unsettled situation.In addition, because charged by main power source device 20 and 30～50 pairs of secondary cells 12 of a plurality of the 1st～3rd auxiliary power devices, so can carry out rapid charge; Have again, because can reduce the capacity of each supply unit 20～50, so, can provide a kind of not only cheap but also can realize small-sized, light-weighted charging device.

The charging action that accordingly, can prevent current control circuit 32 stops after-current control circuit 32 and again moves the situation of (work).That is to say, resistance R 3 and switch element Q1 have formed the anti-stop element of vibration.
Like this, in the 1st auxiliary power device 30 of the 2nd embodiment, can not need to use latch circuit 35.
