Detailed Description
The present invention will be further described with reference to the following specific embodiments.
Referring to fig. 1, the present invention provides a charger capable of increasing the service life of a rechargeable battery or the total charge/discharge capacity, including a central processing unit 4 for controlling the operation of the whole circuit; a control unit 8 for detecting and controlling the charging and discharging output voltage and current; a display unit 6 for displaying a charging state and a charging mode; a selection button 5 for adjusting a battery charge and discharge mode for a user; the control unit 8, the display unit 6 and the selection button 5 are respectively electrically connected with the central processing unit 4. The display unit 6 typically comprises a display screen.
Preferably, the power supply 1 includes a battery unit (not shown), an external ac power supply 2, and a power supply controller 3 that converts ac power to dc power. The power controller 3 is electrically connected with the central processing unit 4, the control unit 8 and the display unit 6 respectively.
Preferably, the control unit 8 includes a first resistor R1, a second resistor R2, a third resistor R3, and a MOS transistor 7 (i.e., a MOS transistor), wherein a first end of the first resistor R1 is electrically connected to the positive electrode of the battery unit, a second end of the first resistor R1 is electrically connected to the first end of the second resistor R2 and the central processing unit 4, respectively, a second end of the second resistor R2 is electrically connected to the central processing unit 4, a first end of the third resistor R3 is electrically connected to the positive electrode of the battery unit, the second end of the first resistor R1, and the first end of the second resistor R2, a second end of the third resistor R3 is electrically connected to the second end of the MOS transistor 7, and a first end of the MOS transistor is electrically connected to the central processing unit 4.
The battery charging mode generally includes 2 types, namely a deep charging mode in which the rechargeable battery can be fully charged and a protective charging mode in which the rechargeable battery is not fully charged, and generally can be charged to about 80%. In the protective charging mode, the battery has a longer service life. When the user first presses the selection button 8 to select the desired charger operating mode, the cpu 4 can detect the voltages of the first resistor R1 and the second resistor R2 and the current of the third resistor R3, and can know the total voltage and the total current of the battery. During charging, if the total voltage of the battery is detected to be too large, a protective charging mode is generally selected, in this mode, when the voltage of the battery reaches 80% of the full load, the central processing unit 4 controls the MOS transistor 7 to be turned off, and charging is stopped, so that the battery cannot be fully charged, the battery capacity is generally set to 80%, the rechargeable battery is protected, the service life of the rechargeable battery is prolonged, and the total charging and discharging capacity of the rechargeable battery is increased.
