Embodiment one
Please refer to Fig. 1, it is the circuit block diagram according to the battery with multi-output voltages of preferred embodiment one of the present invention.Assembly 10 with multi-output voltages comprises a battery body 100, a plurality of battery unit 121 to 124 and a Power Management Unit 130.Present embodiment is to be example with four battery units 121 to 124, but not as qualification, assembly 10 can have two or above battery unit.Battery unit 121 to 124 all is arranged in the battery body 100 with Power Management Unit 130.Different electronic components 31 to 34 uses these battery units 121 to 124 in a plurality of different supply power voltage to electronic installations 30 in order to export.In the present embodiment, the supply power voltage of battery unit 121 to 124 for example is respectively 5V, 3.3V, 1.8V and 1.5V.Power Management Unit 130 is electrically connected to these battery units 121 to 124, in order to state according to these battery units 121 to 124, to convert an external voltage to a plurality of charging voltages, and corresponding these charging voltages of output to battery unit 121 to 124 with to battery unit 121 to 124 chargings, wherein, the size of the charging voltage of arbitrary battery unit is the size that is equal to its supply power voltage.In the present embodiment, external voltage for example is 19V, and corresponding these four battery units 121 to 124, supply power voltage and charging voltage are respectively 5V, 3.3V, 1.8V and 1.5V.Supply power voltage 5V for example provide keyboard controller, basic input/output system (Basic Input/Output System, BIOS), (Universal Serial Bus USB) waits electronic component to USB; Supply power voltage 1.5V for example offers system electronic elements such as memory, display card passage.And its core voltage of different central processing units and different, for example the highest 3.5V that can reach, minimum have only 1.475V.Yet the continuous evolution of the specification of electronic component and technology, each supply power voltage value of Ti Chuing is only for explanation usefulness, not as qualification herein.
When battery unit 121 to 124 is all under the state of electric weight abundance, in fact also need not be to battery unit 121 to 124 chargings, at this moment, battery unit 121 to 124 exportable enough voltages out of the ordinary use for the different electronic components in the electronic installation to electronic installation.Yet,, make the velocity of discharge of battery unit 121 to 124 also inequality because electronic component can have power consumption not of uniform size because of different factors such as its purposes, circuit structures.By the setting of Power Management Unit 130, after these battery units 121 to 124 used a period of time, assembly 10 itself was the action that the electric weight deficiency of discernable which battery unit need be charged.
Please refer to Fig. 2, it is the circuit block diagram that Fig. 1 further shows Power Management Unit 130.Power Management Unit 130 comprises an input 131, a testing circuit 133, a decision circuitry 135 and a bleeder circuit 137.Input 131 is in order to receive external voltage.Testing circuit 133 is in order to detect the state of battery unit 121 to 124.Decision circuitry 135 goes to judge whether to battery unit 121 to 124 chargings in order to the state of the battery unit 121 to 124 that detected according to testing circuit 133.Whether bleeder circuit 137 converts external voltage to charging voltage in order to the judged result according to decision circuitry 135 with decision, and corresponding output charging voltage is to the battery unit that needs charging.
Except the low excessively situation of electric weight, when the battery unit fault, also can't normally provide voltage to use to electronic component, therefore, can be aided with the use of a reserve battery unit, with temporary transient replacement abnormal battery unit of powering.
Please refer to Fig. 3, it is the circuit block diagram of the battery use reserve battery unit of Fig. 1.Assembly 10 is except having aforesaid battery unit 121 to 124 and Power Management Unit 130, and other has reserve battery unit 140, control transformation circuit 150 and a plurality of switch elements 161 to 164.Reserve battery unit 140 is in order to provide a standby voltage.Switch element 161 to 164 distinctly is electrically connected to the output of battery unit 121 to 124, and is electrically connected to electronic component 31 to 34 (see figure 1)s of electronic installation 30.Control transformation circuit 150 is electrically connected to reserve battery unit 140, Power Management Unit 130 and switch element 161 to 164.When Power Management Unit 130 detects the abnormal battery unit of a power supply, be to transmit signal to control transformation circuit 150, and control transformation circuit 150 can switch corresponding switch element according to this, and the standby voltage of reserve battery unit 140 is converted to the supply power voltage of this abnormal battery unit of powering, to output to corresponding electronic component.
Because reserve battery unit 140 only is used for a certain battery unit and powers and use when undesired, need not have bigger volume as other battery unit 121 to 124, and can make the electric weight of the electric weight of reserve battery unit 140 less than battery unit 121 to 124.Preferably, the electric weight of reserve battery unit 140 be about battery unit 121 to 124 electric weight 1/10th.
Be example with battery unit 124 equally, when Power Management Unit 130 detect battery unit 124 electric weight too small need the charging, or battery unit 124 faults and can't output voltage the time, Power Management Unit 130 can be transmitted signal to control transformation circuit 150, switch the switch element 164 of corresponding battery unit 124 by control transformation circuit 150, go to close the voltage output of battery unit 124, and make reserve battery unit 140 by control transformation circuit 150 and switch element 164, temporarily replace battery unit 124 output voltages.Control transformation circuit 150 is the supply power voltages (1.5V) that the standby voltage of reserve battery unit 140 are converted to battery unit 124.
The battery unit 121 to 124 and the reserve battery unit 140 of present embodiment all can be the replaceable type battery unit.Thereby, when aforementioned arbitrary battery unit fault, can directly battery unit be taken out to replace new battery unit from assembly 10.In addition, change the battery of fault, when Power Management Unit 130 also can be used to detect the abnormal battery unit of a power supply, produce a warning signal for reminding the user.
Above-mentioned explanation all is to be arranged in the battery body 100 with Power Management Unit 130 to explain, yet not as qualification, Power Management Unit 130 also can be arranged on outside the battery body 100, or can just be connected with battery body 100 when needs.Please respectively with reference to Fig. 4, Fig. 5, Fig. 4 is that the Power Management Unit 130 of Fig. 1 is arranged on the circuit block diagram outside the battery body 100, and Fig. 5 is that the Power Management Unit 130 of Fig. 3 is arranged on the circuit block diagram outside the battery body 100.When only using assembly 10 power supplies, in fact can not install Power Management Unit 130.When assembly 10 need go charging or will power to electronic installation by external voltage simultaneously by external voltage, again Power Management Unit 130 is connected with battery body 100, to carry out steps such as above-mentioned charging, power supply.Certainly, Power Management Unit 130 can not be connected with battery body 100 when being used for assembly 10 charging yet, with the state that detects battery unit 121 to 124 whether normally, electric weight abundance etc. whether.In addition, Power Management Unit 130 also can be set directly in the electronic installation of being powered by assembly 10.
