DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to the drawings, in particularly to Figures 1 and 2, according to a preferred embodiment of the present invention, the mobile OAU CS JOl.dot//iv phone battery pack 1 with recording device for memorizing the recharged number of times of the present invention interacts with a battery charger 2 with a display 21 for displaying the total recharged number of times of the battery I on the display 21. Typically, the battery pack I is provided with a positive power terminal a negative power terminal GND, and a data output terminal
DATA.
The display type battery charger 2 is formed with a charging receptacle 22 having a number of metal contacts 23a, 23b, and 23c arranged thereon for contacting to the positive power terminal negative power terminal
GND,
and data output terminal DATA of the battery 1 respectively when placing the battery 1 in the charging receptacle 22. Usually, the charger 2 is further formed with a mobile phone charging receptacle 28 for a mobile phone being inserted therein directly and recharged.
Preferably, as shown in Figure 2, excepting a full charged indicator 24 and a charging indicator 25, the battery charger 2 is further arranged with a LCD display 21 for displaying the total recharged number of times of the mobile phone. Furthermore, a number of charging status indicators 26 may be arranged on an area near the display 21 for showing the charging condition and capacity of the battery.
20 With reference to Figure 3, the mobile phone battery pack 1 of the present invention comprises a battery casing composed of an upper casing and a lower casing 10b assembling together to form an inner space for Sreceiving a battery unit 3 therein. The positive power terminal the negative power terminal GND, and the data output terminal DATA are arranged on the upper casing 10a of the battery pack 1. The data output terminal DATA may be arranged in a line the same as the positive power terminal V+ and the negative power terminal GND or in another suitable place on the upper casing A printed circuit board 11 is fixed in a suitable place in the inner space between the upper casing 10a and the lower casing 10b, having a positive power line a negative power line GND', and a data output line DATA'.
The positive power line and the negative power line GND' are correspondingly connected to the positive power terminal V+ and the negative power terminal GND on the upper casing 10a respectively, and the data output line DATA' is connected to the data output terminal DATA on the upper casing A control circuit is arranged on the printed circuit board 11 for recording the number of recharged times. When placing the battery 1 in the charging receptacle 22 for recharging, the charged number of the times memorized in the recording device will be sent out from the data output terminal DATA of the battery 1 to the battery charger 2 and be displayed on the display 21 of the charger 2.
Figure 4 is a schematic circuit diagram of the control circuit of the present invention. The battery charger 2 comprises a charging circuit 27 and a display 21. The positive power line and the negative power line GND' of the charger 2 are connected to the positive power terminal V+ and the negative power terminals GND of the battery respectively when charging.
The recording device for memorizing the recharged number of times comprises a battery charging detecting circuit 41 connected with the battery unit 3 of the mobile phone battery 1. When detecting a charging current passing through the battery unit 3 of the battery 1, the battery charging S 20 detecting circuit 41 will generate a triggering signal S1 to the central processing unit 42.
A reference clock generating circuit 43 connects to the central processing unit 42 for producing a reference clock signal CLK. The central processing unit 42 can receive the triggering signal S1 produced by the battery charging detecting circuit 41 and the reference clock signal CLK produced by the reference clock generating circuit 43.
A recharged times recording unit 44 is connected to a data port of the central processing unit 42, capable of recording the total recharged number of times of the battery 1. When the central processing unit 42 receives the triggering signal S1 produced by the battery charging detecting circuit 41, the central processing unit 42 will start counting based on the reference clock signal CLK. When a predetermined accumulating recharging time, such as two hours in fast charging mode or eight hours in slow charging mode, the total number recorded in the recharged times recording unit 44 will be increased by one under control of the central processing unit 42.
Different type of mobile phone battery pack, such as Ni-H or Lithium battery, has different electric characteristic, therefore the recharging time needed is various. Besides, the habit differs from each user when recharging the battery. The problems of various types of the battery and different using habits may be easily overcome by modifying the program of the central processing unit.
Besides, a series data output device 45 has a data input terminal connected to an output port of the central processing unit 42 and an output terminal connected to the data output line DATA', for sending out the total recharged number of times memorized in the recharged times recording unit 44 to the battery charger 2 through the data output line DATA'. So, the recorded total recharged number of times of the battery may be displayed on the display 21 of the battery charger 2.
Furthermore, the battery pack of the present invention further comprises a battery information recording device 46 for recording various internal information of the battery 1, such as battery type, date of production, batch number, series number, rated voltage, and rated current. All these data may be also sent to the charger 2 through the data output line DATA' under control of the central processing unit 42.
Figure 5 shows the further control circuit of the battery charging detecting circuit in Figure 4, comprising a series resistor 410 and a current differential amplifier 411. The series resistor 410 is connected with the battery unit 3 in series. The current differential amplifier 411 has two input terminals connected to the two terminals of the series resistor 410 in parallel, so that the charging current Ic passing through the battery unit 3 may be detected. Upon detecting the charging current Ic, the current differential amplifier 411will generate a triggering signal S1 to the central processing unit 42.
The battery charging detecting circuit 41 further comprises a switch element 412 having a gate terminal connected to the output terminal of the current differential amplifier 411. When the triggering signal S 1 is produced, the switch element 412 will be switched on, so that the electric power of the battery unit 3 may be supplied to the power source terminal Vcc of the central processing unit 42. Alternatively, when the triggering signal S1 is not produced, the switch element 412 will be switch off to suspend the power to the central processing unit 42 so as to save-electric power energy.
Although the present invention has been described with respect to the preferred embodiment, it is contemplated that a variety of modifications, variations and substitutions may be done without departing from the scope of the present invention that is intended to be defined by the appended claims.
