PCThat is all, the operation that the question blank 80 that microcontroller 60 does not need to be noted down in the reading cells 70 is inquired about.
In the present embodiment, storage unit 70 is made up of the internal memory of rewritable (re-writable), therefore, the user can increase and decrease arbitrarily and is stored in the corresponding relation in the question blank in the storage unit 70, for example the user can see through the corresponding relation of software 30 one group of new model of input and its charging specification, this corresponding relation can be sent to microcontroller 60 via bridge interface 50 by computer installation 20, and is deposited in the question blank 80 in the storage unit 70 by microcontroller 60.Method then is via the network on-line of computer installation 20 supplier to charging device 10 more easily, by stored corresponding relation in supplier's regular update question blank 80, the action that the user only need download and upgrade gets final product, and does not need to key in voluntarily data.In addition, the function of voltage appointment can also be utilized to add an adjustment switch (showing in the diagram) on charging device 10,110, utilizes this switch to set needed voltage to reach the function of voltage appointment.
Above-mentioned all signals by computer installation 20 input charging devices 10 are transmitted by the communication interface of general computing machine, for example general serial connection bus (USB) interface, IEEE 1394 interfaces or RS-232 serial port interface etc., so the bridge interface 50 of charging device 10 also must be and computer installation 20 corresponding general bus (USB) interfaces that are connected in series, IEEE 1394 interfaces or RS-232 serial port interface, and these interfaces all provide power supply terminal (power pin) to use for external device, so the input power supply P of charging device 10 can also be is directly provided by the power supply terminal of bridge interface 50, see also Fig. 2, Fig. 2 is the functional block diagram of the charging device 110 of second embodiment of the invention.Among this embodiment, input power supply P directly transfers to power-switching circuit 90 by bridge interface 50, and thus, charging device 110 just can save power supply input adapter 40, all makes moderate progress on cost and small product size.
For charging device shown in Figure 2 110, though it is because application bridge connection interface 50 receives control signal S in the lump from computer installation 20
cCan reach the purpose that reduces production costs with product size with input power supply P, but have now as industry, the power supply that above-mentioned Computer Communications Interface (for example USB interface, IEEE1394 interface or RS-232 serial port interface) can provide has its upper limit, so, the needed charging voltage V of the rechargeable battery in electronic installation 11
COr charging current I
CWhen big, the power-switching circuit 90 in the charging device 110 just can't produce enough charging voltage V from the input power supply P that computer installation 20 is drawn according to bridge interface 50
COr charging current I
C, that is 110 voltage range or the range of current that can support of charging device are less.For charging device shown in Figure 1 10, it is provided with independently power supply input adapter 40, therefore can capture enough power supplys from computer installation 20, so, the needed charging voltage V of the rechargeable battery in electronic installation 11
COr charging current I
CWhen big, the power-switching circuit 90 in the charging device 110 still can directly draw input power supply P from computer installation 20 by power supply input adapter 40 and produce enough charging voltage V
COr charging current I
CThough charging device 10 causes the increase of production cost and product size because power supply input adapter 40 is set, yet 10 charge voltage ranges that can support of charging device or charging current scope can be bigger than charging device 110.The user can be according to selecting a use in its demand self charger 10,110.
Please note, the stand-alone product that charging device 10,110 of the present invention can be arranged on outside the computer installation 20, for example charging device 10,110 itself is for can being external in the portable apparatus of computer installation 20, and links via power lead/transmission line and computer installation 20.Yet, charging device 10,110 also can in be built in the computer installation 20 so that computer installation 20 (a for example mobile computer) itself promptly has charge function, for instance, charging device 110 can be directly and the motherboard in the computer installation 20 be incorporated into same printed circuit board (Printed Circuit Board, PCB) on, and on computer installation 20 casings, establish a charging connectivity port so that power-switching circuit 90 can charge the connectivity port and is connected to each other with an electronic installation that need charge 11 via this, suppose that bridge interface 50 is to be a pci interface, then charging device 110 just can receive control signal S via the pci bus of computer installation 20
cWith input power supply P.In addition, charging device 10,110 also can make general integrated circuit board (add-on card), therefore its can be inserted on the expansion slot of motherboard and as existing integrated circuit board usually be installed on the housing of computer installation 20, suppose that above-mentioned expansion slot is that then charging device 110 just can receive control signal S via the pci bus of computer installation 20 for the bridge interface 50 in a PCI expansion slot and the charging device 110 is to be a pci interface
cWith input power supply P; In addition, suppose above-mentioned expansion slot be for the bridge interface 50 in a PCI expansion slot and the charging device 10 be to be a pci interface, then charging device 10 also can be provided with a power supply input adapter 40 separately, the output terminal that makes its power supply unit that is connected in computer installation 20 to be capturing required input power supply P, and receives control signal S via the pci bus of computer installation 20 simultaneously
