Hereinafter, describe the power management apparatus that is used for portable electric appts with reference to the accompanying drawings in detail.Should notice that following description only is exemplary, and the present invention is not limited to disclosed embodiment and available multi-form enforcement.In addition, should note in the following description, make the function that theme of the present invention obscures and the detailed description of configuration in this area omitting.
Fig. 1 illustrates the power management of use one better embodiment according to the present invention and the portable electric appts 1 of control device.Referring to Fig. 1, portable electric appts 1 according to the present invention comprises having the system body 20 of electric battery 51 of coupling on it, and the power input terminal 10 that is connected in system body 20 is connected 12 fuel cell group 30 with bus.
The power input terminal 10 that the data terminal of fuel cell controller 36 is connected to system body 20 in the outlet terminal of DC-DC current transformer 34 and the fuel cell group 30 is connected 12 with bus.
Power management and control module 50 comprise consumed power sensor 53, the consumed power of its real-time sense operation piece 40, are connected in and are used for being stabilized in the voltage with predetermined level by the voltage of power input terminal 10 input and voltage as the operating voltage of operating block 40 is provided; Discharge switch 54 is used in response to discharge control signal the voltage of electric battery 51 being connected in the entry terminal of consumed power sensor 53; Charger 55 is used for the voltage transitions at the outlet terminal place of voltage entry terminal 10 or consumed power sensor 53 is become to have the charging voltage CV of predetermined level, in response to charging control signal CSS electric battery 51 is charged; And control module 56, be used for detecting the generating capacity of fuel cell group 30 and the charging residual capacity of electric battery 51, and be used for by according to producing charging control signal CCS by the generating capacity of the consumed power of the operating block 40 of consumed power sensor 53 sensings, fuel cell group 30 with the corresponding voltage of the charging residual capacity of electric battery 51 and performance limitations signal PLS carries out power management by connecting via bus to send and receive data from it to fuel cell group 30 and electric battery 51.
As shown in Figure 1, the BIOS57 that is used for the basic I/O of control system is arranged between control module 56 and the operating block 40, thereby BIOS57 provides system performance restricting signal SPLS to operating block 40, is used for reducing system clock frequency and reducing ODD or the revolution speed of FDD in response to the performance limitations signal PLS from control module 56 outputs.Yet, should be appreciated that, if control module 56 can directly be regulated the frequency of operating block 40, do not need BIOS57.
The power management of the portable electric appts 1 of Gou Jianing preferably provides from the formation voltage of fuel cell group 30 outputs to operating block 40 when fuel cell group 30 is connected with system body 20 with control device as shown in Figure 1, and stops the discharge path of electric battery 51 simultaneously.
Afterwards, the power management of portable electric appts 1 and control device the output voltage that only uses fuel cell group 30 according to system body 20 in the consumed power of operating block 40, the voltage capacity of fuel cell group 30, when driving operating block 40 electric battery 51 is charged with the voltage capacity of electric battery 51, simultaneously provide the voltage of fuel cell group 30 and the charging voltage of electric battery 51 to operating block 40, perhaps reduce the performance of the system clock frequency of operating block 40, thereby even when the consumed power of operating block 40 temporarily surpasses the voltage capacity of fuel cell group 30 and electric battery 51, can prevent that also locking system is closed with restriction system.
When the consumed power of operating block 40 does not surpass the output voltage of fuel cell group 30, when the output voltage that uses fuel cell group 30 drove operating block 40, as above the power management and the control device according to portable electric appts 1 of the present invention of Gou Jianing charged to electric battery 51.
When the consumed power of operating block 40 surpasses the output capacity of fuel cell group 30, power management and control device discharge to the charging voltage of electric battery 30, to replenish not enough power by the output power of interoperable fuel cell group 30 of suitable management and electric battery 51.
When the voltage sum of fuel cell group 30 and electric battery 51 is not enough to reach the consumed power of operating block 40, the power management of portable electric appts 1 and control device reduce the system clock frequency of operating block 40, and reduce the velocity of rotation of the CD-ROM drive motor of ODD, FDD etc. simultaneously, thereby even when temporarily increasing, consumed power also can suitably control the operation of portable electric appts 1.
Fig. 2 illustrates the process flow diagram that is used for power management and control method, and this method is programmed in the ROM zone of control module 56.
The operation of the power management and the control device of portable electric appts 1 is described in more detail with reference to Fig. 1 and 2.
When the portable electric appts 1 that makes up as shown in Figure 1 moves, the control module 56 of power management in the system body 20 and control module 50 reads and is carried in bus in the scheduled time slot and is connected data on 12, to determine whether fuel cell group 30 is connected (S10) with system body 20.
If determine that in step S10 fuel cell group 30 is not connected in system body 20, then control module 56 output switch control signal SCTL are with closed discharge switch 54 (S12).Therefore, the voltage of electric battery 51 offers operating block 40 as operating voltage by discharge switch 54, consumed power sensor 53 and DC-DC current transformer 52.
If fuel cell group 30 is connected in system body 20, then the output voltage of fuel cell group 30 offers operating block 40 by consumed power sensor 53 and DC-DC current transformer 52.
When as mentioned above the voltage of fuel cell group 30 or electric battery 51 being offered operating block 40 as operating voltage by consumed power sensor 53 and DC-DC current transformer 52, operating block 40 is consumed power in the various operations of carrying out based on the speed of predetermined internal system time clock frequency handling according to user's needs or task.
Like this, be connected consumed power sensor 53 sensings between power input terminal 10 and the operating block 40, and provide consumed power (CP) to the entry terminal A1 and the A2 of control module 56 according to load by operating block 40 consumed current amounts.Though consumed power sensor 53 can some multi-form realizations, it uses the current-sense resistor among the present invention to realize.
Simultaneously, the control module 56 of system body 20 sends data and receives data from it by the fuel cell controller 36 that bus connects to fuel cell group 30, with the connection status of identification fuel cell group 30.Control module 56 also sends data and receives data from it to the fuel cell controller 36 of fuel cell group 30 and the battery controller of electric battery 51 respectively by bus connection 12 and data bus 13 in succession, with the generating capacity of inspection fuel cell group 30 and the charging residual capacity (S14) of electric battery 51.Bus connection 12 and data bus 13 are to can be used as to be used for clock and system management (SM) bus of data transmission or the serial data bus of internal integrated circuit (I2C) bus.
That is, control module 56 compares the consumed power (CP) of the controll block 40 formation voltage capacity (FCVC) with fuel cell group 30, to determine that whether greater than the consumed power (CP) of operating block 40 (S18) formation voltage capacity (FCVC).If the formation voltage capacity (FCVC) of determining fuel cell group 30 in step S18 is greater than consumed power (CP), then control module 56 disabled switch control signal SCTL are to turn-off discharge switch 54 (S20).
Afterwards, control module 56 is analyzed in step S14 by via the information of data bus 13 with the charging residual capacity of the relevant electric battery 51 of the data communication acquisition of electric battery 51, so that determine whether need be to electric battery 51 charge (S22).If determine that in step S22 electric battery 51 has been full of electricity, then control module 56 turns back to above-mentioned initial step.If determine electric battery 51 underfill electricity, then control module 56 activating charge control signal CCS (S24).
In response to the control signal CCS that is activated, charger 55 becomes to have the charging voltage (CV) of predetermined level by the voltage transitions of consumed power sensor 53 with fuel cell group 30, thereby electric battery 51 is charged.
After electric battery 51 chargings, control module 56 is by the battery controller communication data of data bus 13 with electric battery 51, to determine whether accumulator has been full of electricity (S26).If determine the accumulator underfill in step 26, then control module 56 returns above-mentioned initial step.If electric battery 51 is full of electricity, then control module 56 is forbidden charging control signal CCS, thereby makes charger 55 invalid.
Therefore, if the formation voltage capacity of fuel cell group 30 greater than the consumed power of operating block 40, then the voltage of fuel cell group 30 is used for stably driving operating block 40 and electric battery 51 is charged.
If in step S18, determine the formation voltage capacity (FCVC) of the consumed power (CP) of operating block 40 greater than fuel cell group 30, then the discharge path (S30) of control module 56 closed discharge switches 54 to set up the accumulator in the electric battery 51 checked the consumed power (S32) by the operating block 40 of consumed power sensor 53 sensings then.
When discharge switch 54 closures, the charging voltage of electric battery 51 (BAT) is cooperated consumed power sensor 53 with the formation voltage of exporting from fuel cell group 30 (FCVC).That is, the charging voltage of electric battery 51 (BAT) is added on the formation voltage (FCVC) of fuel cell group 30.
In step S32 the consumed power of checked operation piece 40 (CP) afterwards, control module 56 determines whether the consumed power (CP) of operating blocks 40 surpasses the formation voltage capacity (FCVC) of fuel cell group 30 and voltage (BAT) sum (S34) of electric battery 51.
If the consumed power (CP) of determining operating block 40 at step S34 is less than the formation voltage capacity (FCVC) of fuel cell group 30 and voltage (BAT) sum of electric battery 51, then control module 56 jumps to step S16 and uses two driven operating blocks 40 then.
Yet, surpassing the formation voltage capacity (FCVC) of fuel cell group 30 and voltage (BAT) sum of electric battery 51 if in step S34, determine the consumed power (CP) of operating block 40, control module 56 provides performance limitations signal PLS (S36) to BIOS57.
In response to performance limitations signal PLS, BIOS57 reduces the system clock frequency of operating block 40, and the velocity of rotation of motors such as ODD, FDD is limited to than low value.The performance of this process restriction operating block 40, thus its consumed power reduced.
Increase fast if consumed power is temporary transient when operating block 40 is carried out a plurality of task, then control module 56 is no more than the motor rotational speed that the mode of the formation voltage capacity of fuel cell group 30 automatically reduces the system clock frequency of operating block 40 or consumes many power with the consumed power of system body 20.
As mentioned above, if the consumed power of system body 20 surpasses the formation voltage capacity (FCVC) of fuel cell group 30, the discharge path of setting up electric battery 51 according to the power management and the control device of portable electric appts 1 of the present invention then is so that replenish not enough power with the charging voltage of electric battery 51.If the consumed power of system body 20 is no more than the formation voltage capacity of fuel cell group 30 and the voltage underfill of electric battery 51, then power management and control device start charger 55, thereby make the level of the charging voltage of electric battery 51 always be in full state.
If the voltage sum of the formation voltage of fuel cell group 30 and electric battery 51 is less than the consumed power of operating block 40, then power management and control device carry out suitable power management by the performance of restriction operating block 40, and the mode that next consumed power with operating block 40 is no more than the formation voltage capacity of fuel cell group 30 reduces total power consumption.
Portable electric appts is not limited in notebook, and can be the various battery powered electronic equipment such as PDA, communication facilities, portable data assistance and camera.
As mentioned above, according to the present invention, undertaken by the performance of electric battery being carried out charge/discharge and restriction operating block from the consumed power of the power management in the battery-powered portable electric appts of fuel by real-time policer operation piece, according to the formation voltage capacity of the operating block consumed power of institute's sensing and fuel cell group.Even when many power temporarily consume, can prevent that also this system is closed in system body therefore.
