Embodiment
The embodiment of rechargeable battery of the present invention and charging device thereof is described below in conjunction with accompanying drawing.
As shown in Figure 1, this rechargeable battery 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).
