Embodiment
The embodiment of battery charger of the present invention and suitable rechargeable battery thereof is described below in conjunction with accompanying drawing.
As shown in Figure 1, the rechargeable battery in the present embodiment comprises, the lithium ion circuit that charges and discharge that electric core and the protective circuit that is connected electric core and reduction voltage circuit form that charges.
Because lithium-ion electric core to relatively strictness of voltage request, overcharges and overdischarge all can damage battery, so we have adopted the special-purpose single-unit li-ion cell protection chip U1 of company of Ricoh, model is R5426.By sealing in the break-make that the very little field effect transistor U2-A of two impedances and U2-B control charging and discharging circuit on the circuit charging and discharging, to reach the effect of protection battery, its circuit theory diagrams as shown in Figure 2.The described circuit that charges and discharge also comprises triode Q1, capacitor C 1～C2 and resistance R 1～R2; Described field effect transistor U2-A and U2-B are connected in series mutually, and their signal input end connects signal output part CO and the DO of chip U1 respectively.
Its operation principle is that the control signal of field effect transistor is by the voltage and the size that charges and discharge the electric current on the circuit of U1 detecting lithium-ion electric core.When electric core overtension, U1 control U2-A disconnects, and stops charging.When electric core brownout or discharging current were excessive, U1 control U2-B disconnected, and stops discharge.Prevent that electric core from overcharging and the purpose of overdischarge thereby reach.So its protective circuit is the combination of overvoltage protection, under voltage protection and overcurrent protection.
Lithium cell voltage generally arrives 4.2V at 3.6V, and is if directly to the power device power supply of nominal 3V voltage, obviously too high.Be to reduce voltage, we have used a transistor Q1 to seal between the charging negative pole of protective circuit and the discharge negative pole that is connected load.When battery operated, generally have electric current by the time have the 0.7V-0.8V pressure drop on the triode, like this, the voltage that the load two ends obtain will be dropped to about 3V.Certainly, this voltage is not steady state value, can change with cell voltage, but this changing value is an acceptable to electronic installation (as digital camera).
As shown in Figure 3, lithium-ion electric core 2 with charge and discharge circuit 1 usefulness bar shaped nickel sheet 6,7 and be connected; Charge and discharge circuit 1 and be fixed on the positive terminal of lithium cell 2 by support 3, double faced adhesive tape 14; The charging negative pole CH-and the discharge negative pole PACK-that charge and discharge circuit 1 are connected to box hat 8 and base plate 81 by bar shaped nickel sheet 5,4 respectively; The anodal BAT+ that charges and discharge circuit 1 passes the central authorities that rubber ring 11 places the top of box hat 8, constitutes the anodal PACK+ of battery; Be separated with fire prevention gummed paper 12 and 121 between lithium cell 2 and bar shaped nickel sheet 4,5,7 and the box hat 8; Inside and outside fast crust paper 9 and 10 of being equipped with respectively of base plate 81 are fixed on the negative pole end of lithium cell 2 by double faced adhesive tape 13.Be packaged in the plastic insulation sleeve pipe after the battery assembling, reserve the anode of battery top center and the charging negative pole of anodal outer ring, and the discharge negative pole of battery bottom.
As shown in Figure 4, battery charger of the present invention comprises the charging main body of input ac power, output low-voltage dc power supply; Circuit is adjusted in the control that is fixed in the charging base that is electrically connected with the charging main body; Be installed in the removable battery case of the contact of charging having on the charging base.
Control in the described charging base is adjusted circuit and is comprised the input circuit that can insert low-voltage dc power supply, connects linear adjustment circuit and charging output circuit successively, and draws and insert the linear feedback control circuit of adjusting circuit from output circuit.Its circuit theory schematic diagram is seen Fig. 5.Described input circuit, linear adjustment circuit and output circuit, and feedback control circuit are on the circuit board 23 of aggregate erection in charging base.
As shown in Figure 6, charging base also comprises: loam cake 21 and lower cover 22, and be fixed on connecing on the circuit board 23 from contact plate 25 of output circuit output etc.
In Fig. 6, have a pair ofly when the combination of battery case and charging base in the battery case, can be electrically connected the charging contact that the output circuit output of circuit is adjusted in control in the charging base respectively.One of them charging contact be installed in battery case one end can with the anodal contacted flexible member 26a of battery top center, another charging contact is the flexible member 26b that can contact with the charging negative pole of anodal outer ring, battery top that is installed in the same end of battery case.Battery case also comprises: battery bracket 27, protective cover 28 and the protective plate 29 of carrying rechargeable battery, the spring leaf 20 that is electrically connected with the charging contact etc.
Battery case can be quick installed on the charging base, when the combination of battery case and charging base, the spring leaf 20 of battery case bottom just with charging base on contact plate 25 conductings.Battery in the battery case is then by flexible member 26a and 26b, and spring leaf 20 and contact plate 25 link with the output circuit that circuit is adjusted in the control in the charging base.
