Description
Technical Field
The disclosure relates to the technical field of vehicle engineering, in particular to an internal combustion engine starting auxiliary device.
Background
In the related art, some motor vehicles include an engine that consumes fuel to output power, and a transmission that converts the power of the engine and outputs the converted power to drive wheels via a differential gear. As a core power portion of the engine, whether the internal combustion engine can be smoothly started is extremely important.
In conventional internal combustion engine starting schemes, the energy required to start the electric motor is typically provided by a lead-acid battery. At the moment of starting the internal combustion engine, the current required to start the motor is in the order of hundreds of amperes to two kiloamperes. Since the internal combustion engine is not normally operated at this time, the generator of the motor vehicle cannot generate electricity, and therefore all the electric energy needs to be solely borne by the lead-acid storage battery.
However, the lead-acid battery is damaged when a large current is discharged, and the service life of the lead-acid battery is shortened to a great extent. In addition, the normal operating temperature range for lead acid batteries is approximately-10 to 50 degrees. In low temperature environments, such as below-10 degrees celsius, lead-acid batteries have difficulty discharging large currents, resulting in difficulty in successfully starting the internal combustion engine. Furthermore, it is difficult to successfully start the internal combustion engine when the lead-acid battery is short of power.
Therefore, it is desirable to provide an engine start assist apparatus that reduces the difficulty of the engine failing to start.

In other instances, well-known structures have not been shown or described in detail to avoid obscuring aspects of the disclosure.
In the present exemplary embodiment, first, a start assist apparatus for an internal combustion engine, which may be, for example, a gasoline internal combustion engine, a diesel internal combustion engine, or the like, is provided. Referring to fig. 1, the internal combustion engine starting auxiliary device in the present exemplary embodiment mainly includes a lithium ion capacitor unit 11, a voltage detection unit 12, a capacitor equalization circuit 13, a first connection unit 14, and a package case 18; of course, those skilled in the art may add new component units, such as indicator lights, control switches, filter circuits, voltage regulator circuits, etc., as needed, and are not limited to the exemplary embodiments. The lithium ion capacitor unit 11 comprises a plurality of lithium ion capacitor groups connected in series; in the exemplary embodiment, the lithium ion capacitor has the advantages of high energy density, high power density, rapid charge and discharge, wide applicable temperature range, many charge and discharge times, no maintenance and the like. The voltage detection unit 12 is connected to each of the lithium ion capacitor banks, and is configured to detect a voltage of each of the lithium ion capacitor banks; the voltage detection unit 12 may be, for example, an AD voltage sampling circuit or a voltmeter. The capacitance equalizing circuit 13 is connected to each lithium ion capacitor group and the voltage detecting unit 12, and is configured to equalize the voltage of each lithium ion capacitor group according to a detection result of the voltage detecting unit 12. The first connection unit 14 is a connection port, the positive output end and the negative output end of the lithium ion capacitor unit 11 are integrated in the first connection unit 14, and the lithium ion capacitor unit 11 can be connected with the internal combustion engine starting battery through the first connection unit 14 and provide a power supply required for starting the internal combustion engine together with the internal combustion engine starting battery. The internal combustion engine starting battery may be, for example, a lead-acid battery, a lithium battery, a nickel metal hydride battery, or the like, and may be used for supplying power to electrical components such as an indicator lamp and an instrument panel in a motor vehicle, in addition to the internal combustion engine. The packaging shell 18 is used for packaging all parts of the internal combustion engine starting auxiliary device into an integrated structure, and the packaging shell 18 can be a resin shell or an alloy shell; the shape of the package housing 18 may be, for example, a cylinder, a cube, or a pseudo-shape, etc.; the package housing 18 may further have a plurality of openings to expose the connection unit and the indicator light.
Referring to fig. 2, the internal combustion engine starting auxiliary device in this example embodiment may further include a second connection unit 15, where the second connection unit 15 is a connection port, the positive input end and the negative input end of the lithium ion capacitor unit 11 are integrated with the second connection unit 15, and the internal combustion engine starting battery is connected to the lithium ion capacitor unit 11 through the second connection unit 15 and may charge the lithium ion capacitor unit 11 through the second connection unit 15. Of course, the second connection unit may be connected to an external dc charger, so as to charge the lithium ion capacitor unit 11 by using the current input by the external dc charger. In other exemplary embodiments of the present disclosure, the first connecting unit 14 and the second connecting unit 15 may have the same structure, and are not limited to the exemplary embodiments.
Referring to fig. 3, when the internal combustion engine starting battery 2 cannot supply a large current, the internal combustion engine starting auxiliary device 1 storing electric energy may be connected to the internal combustion engine starting battery 2 so that the large current required to start the internal combustion engine 3 may be supplied by the internal combustion engine starting auxiliary device 1 together with the internal combustion engine starting battery 2; for example, when the internal combustion engine starting battery 2 is generally insufficient or has too low temperature to discharge large starting current, and the lithium ion capacitor unit 11 of the internal combustion engine starting auxiliary device 1 is sufficient in electric quantity, the internal combustion engine starting auxiliary device 1 may be connected with the internal combustion engine starting battery 2, and the lithium ion capacitor unit 11 and the internal combustion engine starting battery 2 together provide the power supply required for starting the internal combustion engine, wherein the internal combustion engine starting battery 2 provides most of electric energy. For another example, when the internal combustion engine starting battery 2 is severely deficient in power or has too low temperature to release large starting current, and the lithium ion capacitor unit 11 of the internal combustion engine starting auxiliary device 1 is sufficient in power, the internal combustion engine starting auxiliary device 1 may be connected to the internal combustion engine starting battery 2, and the lithium ion capacitor unit 11 and the internal combustion engine starting battery 2 together provide the power supply required for starting the internal combustion engine, where the lithium ion capacitor unit 11 provides most of the power. For example, when the internal combustion engine starting battery 2 is generally insufficient in power or has a too low temperature to discharge a large starting current and the lithium ion capacitor 11 of the internal combustion engine starting aid 1 is short of power, but the output voltage of the internal combustion engine starting battery 2 is still maintained at a voltage higher than a predetermined voltage (for example, 10V or higher), the second connecting means 15 of the internal combustion engine starting aid 1 may be connected to the internal combustion engine starting battery 2, and the internal combustion engine starting battery 2 may charge the lithium ion capacitor 11 of the internal combustion engine starting aid 1 slowly through the second connecting means 15, so that the lithium ion capacitor 11 may charge and discharge a large current quickly, and the internal combustion engine 3 may be started by outputting a large current instantly after the lithium ion capacitor 11 collects sufficient electric energy. For another example, when the internal combustion engine starting battery 2 is severely insufficient or has too low temperature to discharge large starting current, and the lithium ion capacitor unit 11 of the internal combustion engine starting auxiliary device 1 is insufficient in power, the external dc charger may be used to rapidly charge the lithium ion capacitor unit 11 (for example, within 5 minutes), or the second connection unit 11 of the internal combustion engine starting auxiliary device 1 may be connected to the internal combustion engine starting battery 2 with sufficient power in another vehicle to rapidly charge (for example, within 5 minutes), and then connected to the internal combustion engine starting battery 2 in the vehicle to provide the power supply required for starting the internal combustion engine together with the internal combustion engine starting battery 2, wherein the lithium ion capacitor unit 11 provides most of the electric energy.
In other exemplary embodiments of the present disclosure, the internal combustion engine starting auxiliary device 1 may be connected to the internal combustion engine starting battery 2 for a long time, and provide a large current required for starting the internal combustion engine 3 together, so that the current that the internal combustion engine starting battery 2 needs to provide alone can be greatly reduced, damage to the internal combustion engine starting battery 2 due to the provision of the large current is reduced, and the service life of the internal combustion engine starting battery 2 is prolonged.
Further, referring to fig. 4, in other exemplary embodiments of the present disclosure, the engine start assist device may further include an output circuit 16 and a charging circuit 17.
In the present exemplary embodiment, the output circuit 16 is disposed between the lithium ion capacitor unit 11 and the first connection unit 14, and is configured to convert the electric energy stored in the lithium ion capacitor unit 11 into a current of a specific magnitude and output the current. The charging circuit 17 is disposed between the lithium ion capacitor unit 11 and the second connection unit 15, and is configured to convert an external input current and then charge the lithium ion capacitor unit 11. The output circuit 16 may include a DC/DC conversion circuit, which is configured to convert the electric energy stored in the lithium ion capacitor unit 11 into a required direct current and output the direct current, and the DC/DC conversion circuit may be, for example, a basic chopper circuit, a complex chopper circuit, or the like. In the present exemplary embodiment, the charging circuit 17 may be connected to a dc charger. The direct current charger may include a transformer and a rectifying circuit. The transformer is used for converting the voltage of the external alternating current power supply to a preset voltage, and the transformer can be a thin film transformer, a PCB type transformer and the like. The rectifier circuit is connected to the transformer and used for rectifying the ac power, and the rectifier circuit may be, for example, a bridge rectifier circuit, a half-wave rectifier circuit, or the like. The dc charger may be a dc charger that can output a large current in the related art, or may be a dc charger that is produced specifically for charging the internal combustion engine starting aid 1 in the present exemplary embodiment. In addition, in order to charge the internal combustion engine start-up assisting apparatus 1 at any time, avoid the situation that the internal combustion engine start-up assisting apparatus 1 cannot be charged due to forgetting to carry the dc charger, and reduce the messy charging wires, in other exemplary embodiments of the present disclosure, the transformer, the rectifying circuit, and the like may be integrated into the internal combustion engine start-up assisting apparatus 1. For example, the charging circuit 17 may include the transformer and the rectifying circuit described above.
Further, in order to improve the voltage resistance of the lithium ion capacitor unit, the lithium ion capacitor unit 11 in this exemplary embodiment may include a plurality of lithium ion capacitor groups connected in series. In the present exemplary embodiment, the number of the lithium ion capacitor groups connected in series may be 2 to 10, for example, for a 12V internal combustion engine start-up auxiliary device, 4 lithium ion capacitor groups may be generally connected in series, and for a 24V internal combustion engine start-up auxiliary device, 8 lithium ion capacitor groups may be generally connected in series. With the technical progress of lithium ion capacitors and the improvement of voltage level, 3 lithium ion capacitor groups can be connected in series for a 12V internal combustion engine starting auxiliary device, and 6 lithium ion capacitor groups can be connected in series for a 24V internal combustion engine starting auxiliary device.
Referring to fig. 5A, in the present exemplary embodiment, each of the lithium ion capacitor sets 111 may include 1 lithium ion capacitor. Alternatively, as shown in fig. 5B, each of the lithium ion capacitor sets 111 may include a plurality of lithium ion capacitors connected in parallel. By providing lithium ion capacitors in parallel, greater capacitance can be provided, which in turn can provide greater current and greater energy. According to different capacitance requirements, the number of lithium ion capacitors that need to be connected in parallel is different, for example, in the present exemplary embodiment, each lithium ion capacitor group 111 may include 2 to 100 lithium ion capacitors that are connected in parallel. Alternatively, as shown in fig. 5C, each of the lithium ion capacitor sets 111 includes 1 lithium ion capacitor, and the plurality of lithium ion capacitor sets 111 connected in parallel are a lithium ion capacitor row 112; the lithium ion capacitor unit 11 comprises a plurality of lithium ion capacitor columns 112 connected in parallel; as described above, different capacitance can be provided by connecting different numbers of lithium ion capacitor arrays 112 in parallel, so as to meet different starting current requirements; in the present exemplary embodiment, the number of the lithium ion capacitor rows 112 may be, for example, 2 to 100.
Due to the limitations of materials and processes, the capacity and internal resistance of the same type of lithium ion capacitor may also differ. This causes a difference in voltage between the lithium ion capacitor groups 111 connected in series, and if the lithium ion capacitor groups are not equalized for a long time, the lithium ion capacitors may be finally unusable. In this exemplary embodiment, the capacitance equalizing circuit 13 may include a discharging circuit, so that a capacitor with a voltage higher than a preset voltage may be discharged to equalize the voltage of each lithium ion capacitor group 111, where the preset voltage may be set according to actual requirements. The voltage detected by the voltage detection unit 12 can identify the lithium ion capacitor group 111 with an excessively high voltage, and can select to discharge the lithium ion capacitor group. Alternatively, the capacitance equalizing circuit 13 may discharge the lithium ion capacitor group 111 having a voltage higher than the preset voltage to the lithium ion capacitor group 111 having a voltage lower than the preset voltage to equalize the voltages of the lithium ion capacitor groups 111, for example, the lithium ion capacitor group 111 having the highest voltage and the lithium ion capacitor group 111 having the lowest voltage may be identified by the voltage detected by the voltage detecting unit 12, and the lithium ion capacitor group 111 having the highest voltage may be discharged to the lithium ion capacitor group having the lowest voltage by a DC/DC converting circuit, thereby implementing voltage equalization of the lithium ion capacitor groups 111. Of course, the voltage equalization of each lithium ion capacitor group 111 may be realized by other manners by those skilled in the art, and is not limited to the manner illustrated in the present exemplary embodiment.
In summary, in the internal combustion engine start-up auxiliary device in the exemplary embodiment, by providing the lithium ion capacitor unit, the voltage detection unit, the capacitor equalization circuit and the connection unit, on one hand, by using the lithium ion capacitor which has high energy density, high power density, rapid charge and discharge, wide applicable temperature range, many charge and discharge times and is maintenance-free and which is used for providing an auxiliary power supply during the internal combustion engine start-up process, a large current required by the internal combustion engine start-up can be provided at any time and in more environments, thereby ensuring the internal combustion engine to start up smoothly; on the other hand, the voltage detection unit and the capacitor balancing circuit can ensure the voltage balance of each lithium ion capacitor group in the lithium ion capacitor unit so as to protect the lithium ion capacitor unit and prolong the service life of the lithium ion capacitor unit.
The present disclosure has been described in terms of the above-described embodiments, which are merely exemplary of the implementations of the present disclosure. It must be noted that the disclosed embodiments do not limit the scope of the disclosure.
