Battery device
View Patent ↗The present disclosure discloses a battery device including a battery, a charging and discharging switch unit configured to control charging and discharging of the battery, a pre-charging unit configured to be charged during discharging of the battery, and a discharging unit configured to discharge the charge charged in the pre-charging unit.
1. A battery device comprising:
a battery;
a charging and discharging switch unit configured to control charging and discharging of the battery, wherein the charging and discharging switch unit comprises a first switch and a second switch provided between the battery and a load;
a pre-charging unit that is installed between the battery and the charging and discharging switch unit, and that is configured to be charged during discharging of the battery;
a discharging unit configured to discharge the charge charged in the pre-charging unit during turning off of the charging and discharging switch unit; and
a driving unit configured to control the first switch and the second switch,
wherein the discharging unit comprises a diode provided between the pre-charging unit and the driving unit.
2. The battery device of claim 1 , further comprising a load capacitor connected in parallel to the load.
3. The battery device of claim 1 , wherein the driving unit comprises:
a state detection unit configured to detect the state of the battery;
a control unit configured to generate a control signal for driving the charging and discharging switch unit using detected data of the state detection unit; and
a signal output unit configured to output the control signal to the charging and discharging switch unit.
4. The battery device of claim 3 , wherein the driving unit compares the detected data of the state detection unit with a reference data, and controls the first switch and the second switch.
5. The battery device of claim 2 , wherein the pre-charging unit comprises at least one capacitor provided between the battery and the first switch.
6. The battery device of claim 5 , wherein the at least one capacitor is charged when the first switch and the second switch are turned on and the battery is discharged.
7. The battery device of claim 6 , wherein the pre-charging unit is charged prior to the load capacitor, adjusting the charging time of the load capacitor.
8. The battery device of claim 1 , wherein the diode discharges the charge charged in the pre-charging unit after the first switch and the second switch are turned off.
