Detailed Description
The present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
According to the technical scheme of the embodiment of the invention, the charging and discharging circuit is packaged into the dummy battery with a preset size, and the dummy battery and any one or more columnar batteries with the same size are installed and used according to the existing battery pack assembly mode, so that stable output voltage can be obtained. In another embodiment of the present invention, a voltage regulation control circuit may be further packaged in the dummy battery, so as to further obtain an output voltage preset by a user.
Fig. 2 is a schematic structural diagram of a system with adjustable output voltage according to an embodiment of the present invention. As shown in fig. 2, the cylindrical battery connected to the positive electrode of the battery case is replaced with a dummy battery. The positive electrode of the dummy cell was connected to the positive electrode of the battery case, and the left side of the dummy cell was the positive electrode thereof as shown in fig. 3. The intermediate electrode of the dummy cell is connected to the negative electrode of the battery case, and as shown in fig. 3, the intermediate electrode of the dummy cell is connected to the negative electrode of the first cell in the battery pack through a wire. The negative pole of the dummy cell is connected to the cell group formed by other cells in the cell group, thereby forming a series circuit with other cells, and as shown in fig. 3, the right side of the dummy cell is the negative pole thereof, which is connected to the positive pole next to another cell. The other cells in the battery pack will be any cylindrical cell of the same type. In an embodiment of the invention, the middle electrode of the dummy battery and the negative electrode of the battery box may be connected by another cable.
For example, 3 lithium ion batteries (the total output is 9 volts at the lowest, and the maximum output is 12 volts) and a dummy battery are combined into a battery pack, and the constant output is 6 volts.
Fig. 3 is a schematic structural diagram of a dummy cell with adjustable output voltage according to an embodiment of the present invention. As can be seen from fig. 3, the dummy battery comprises a control circuit, two switches, an inductance and a capacitance. When the switch on the left side shown in fig. 3 is turned off and the switch on the right side shown in fig. 3 is turned on, the negative electrode and the middle electrode of the dummy battery are respectively connected with other batteries of the battery pack to form a closed-loop charging circuit, and the other batteries of the battery pack charge the inductance of the dummy battery. When the switch on the left side shown in fig. 3 is turned on and the switch on the right side is turned off, a discharge circuit is formed to output a predetermined voltage through inductive discharge, and the positive electrode and the middle electrode of the dummy cell are the two poles of the output voltage.
Wherein the control circuit comprises a switch control circuit for automatically controlling the opening and closing of the two switches shown in fig. 3.
In an embodiment of the present invention, the dummy battery further includes a voltage regulation control circuit, an output voltage detection circuit, a voltage setting detection circuit, and a voltage setting knob. Wherein, the user sets up the predetermined output voltage of whole group battery (non-single false battery) through the voltage setting knob, and voltage setting detection circuitry is used for detecting the user and sets up the predetermined voltage of knob through the voltage. The voltage regulation control circuit can automatically regulate the circuit according to the input voltage, the voltage of other batteries of the connected battery pack, and the output voltage, which is set by a user through the voltage setting knob, so as to ensure constant output. The output voltage detection circuit detects the output of the whole battery pack and feeds back the information to the voltage regulation control circuit in real time.
The input voltage in the control circuit may be higher than the output voltage or lower than the output voltage.
It will be appreciated by those skilled in the art that in one embodiment of the invention, the voltage setting may be performed by other paths than by the user setting the voltage via the voltage setting knob.
In an embodiment of the present invention, the dummy battery setting may not include a voltage setting knob, and in this case, may be implemented by setting a fixed output voltage in advance.
In an embodiment of the present invention, the voltage regulation control circuit may be a buck-boost circuit.
By utilizing the technical scheme provided by the embodiment of the invention, the column-shaped battery with the same size can be matched with any column-shaped battery with the same size through a section of dummy battery circuit which does not accumulate electricity, and a stable output voltage preset by a user can be obtained no matter how large the electricity accumulation amount of the column-shaped battery is (only a charging circuit which is enough to support the dummy battery is needed). Therefore, various columnar batteries can be replaced and used on any electric equipment.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
