Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the generator merge charger according to an embodiment of the present invention.

First, as can be seen through Figure 1, the generator merge charger 100 according to the present invention, the charger 110, 120 including the general charger 110 and the rapid charger 120, and the generator 130 is integrated And the electromagnetic shielding shield S and the vibration absorbers P and C are inserted between the chargers 110 and 120 and the generator 130, and they are accommodated in the charger case B.

The general charger 110 includes a charging wire 111 and a charging power connection plug 112 connected to an end of the charging wire 111. Similarly, the generator 130 includes a power generation wire ( 131, and a power supply plug 132 for generation, the general charger 110 is a commercial power supply (AC 60Hz, 220 [v], may vary by country) through the charging power connection plug 112 In response to the input, the generator 130 is operated by receiving commercial power through various fuels, as well as the power supply plug 132 for power generation.

Accordingly, the secondary battery B (hereinafter, referred to as a battery) is charged using the general charger 110, the battery B is charged using the rapid charger 120, or the generator 130 is charged. To charge the battery (B). Of course, it is obvious that the battery B can also be charged using these simultaneously.

In addition, in the present invention, the rapid charger 120 may be charged using the general charger 110 or the rapid charger 120 may be charged using the generator 130.

In addition, by the electromagnetic shielding shield (S) and the vibration absorber (P, C), various noises and vibrations generated during operation of the generator 130 is not transmitted to the general charger 110 or rapid charger 120, This improves the charging properties and at the same time improves the durability.

In more detail, the generator merge charger 100 according to the present invention, the charger (110, 120) to charge the battery (B) by using the power supplied from the outside, and mechanical energy by electrical power generation as electrical energy Generator 130 and a controller 160 for controlling the charging of the battery (B) through the generator (110, 120) or the generator 130 to convert to generate a charging energy, wherein the charger (110, 120) ) Includes a general charger 110 and a quick charger (120).

In addition, in addition to the charge monitoring unit 140 and the various control in the controller 160 to monitor the state of charge of the fast charger 120 and the battery B, respectively, and transmits the monitoring result to the controller 160. It includes a program memory 150 in which an application program or reference value to be used is stored.

Here, the general charger 110 receives a commercial power of 220 [v] through a charging power connection plug 112 and converts it (for example, DC 48 [v]) and supplies the battery B by supplying the battery B. ), A power conversion circuit, an overcharge protection circuit, and the like are provided therein, and an output terminal thereof is connected to an input terminal of the battery B.

In addition, the output terminal of the general charger 110 is also connected to the input terminal of the rapid charger 120, the rapid charger 120 made of a large capacity capacitor (see 'C1' of FIG. 4) through the general charger 110 is also Allow it to charge.

The case of directly charging the battery B with the general charger 110 is an example of charging the battery B gradually by inserting the charging power connection plug 112 into an outlet at home, and using the general charger 110. In this case, the rapid charging is performed by charging the rapid charger 120 first and then rapidly charging the battery B using the voltage balance between the rapid charger 120 and the battery B. FIG.

In particular, when the rapid charger 120 is charged by the general charger 110, the power charged in the battery B consumes a certain ratio or more (for example, the power charged in the battery B by driving the electric vehicle is When exhausted), the rapid charger 120 charges the battery B rapidly so that the continuous power supply may be prevented.

The fast charger 120 is composed of a large capacity capacitor (for example, 800 Ah or more) to be sufficient to fully charge the battery B, as shown in FIGS. 3A and 3B. Likewise, the positive and negative electrodes of the large capacity capacitor are connected to the positive and negative electrodes of the battery B, respectively. That is, the positive electrode of the large capacity capacitor is connected to the positive electrode of the battery B, and the negative electrode of the large capacity capacitor is connected to the negative electrode of the battery B.

In addition, as shown in FIG. 3A, a supply switch 121 is connected in series to the output side of the quick charger 120, and the supply switch 121 is controlled to be controlled by the controller 160. Switching control can be used in a variety of ways, including how the controller 160 activates a relay (not shown) installed adjacent to the supply switch 121, and can only be switched rapidly when the supply switch 121 is turned on. Charging is done.

Therefore, when a voltage imbalance condition in which the magnitudes of the voltages charged in the battery B and the large-capacity capacitor constituting the rapid charger 120 are different from each other occurs, the large-capacity capacitor is in the process of voltage balancing between the large-capacity capacitor and the battery B. Charges the battery B rapidly. In this sense, the present invention uses the term 'fast charger'.

However, the high-capacity capacitor constituting the rapid charger 120 as described above also performs the role of a buffer capacitor that can maintain a relatively constant voltage characteristics and supply the power (ie, charging) stably compared to the chemical battery. Obvious at the level of those skilled in the art.

The generator 130 is a small generator attached to a vehicle and used to move by supplying power by converting mechanical energy into electrical energy through self-generation, and an output terminal of the generator 130 is connected to an input terminal of a battery B. The battery B is charged with electrical energy generated by the generator 130.

In addition, the output terminal of the generator 130 is also connected to the input terminal of the rapid charger 120, so that the rapid charger 120 can also be charged through the generator 130.

The generator 130 charges the battery B first during the movement. However, after the charging of the battery B is completed or when there is the remaining power generation after charging the battery B, the rapid charger 120 is charged. This means that even when the battery B takes a long time to be charged, the battery B needs only to replenish the power consumed for the movement by supplying the generated power to the battery B immediately. This is because the charger 120 does not need to be charged first.

In addition, the present invention can significantly shorten the charging time of the battery B by charging the battery B through the generator 130 even when not in motion. For example, compared to the case of charging using the general charger 110, the output is 1.5 [kwh], and the charging is much faster by using the generator 130 having a rated output larger than that of the general charger 110. Allow charging.

Of course, by operating the generator 130 and the rapid charger 120 at the same time can use both of them at the same time to charge the battery (B) more quickly, similarly using the generator 130 and the general charger 110 at the same time You can also charge (B) even faster.

On the other hand, the energy source (that is, fuel) for operating the generator 130 as described above is a commercial power supplied from the outside, such as an outlet provided in the first home, or LPG / CNG supplied through the fuel tank attached to the second vehicle It is an energy source having a relatively small amount of carbon dioxide generation such as / LNG / hydrogen or a rotational energy transmitted from a wheel of a third vehicle.

When the generator 130 is operated by receiving commercial power supplied from the outside, the generator 130 is operated by receiving a commercial power supply by inserting the power connection plug 132 for generation in an outlet in a stationary state while not moving. If it is.

In the case of using an energy source such as LPG / CNG / LNG / hydrogen, the generator 130 is operated by receiving energy such as LPG / CNG / LNG / hydrogen in a moving state. The charger 100 is equipped with a small 1.5kw generator 130 and is provided with a fuel tank having a capacity of 3 kg (250 × L 250 diameter), and filled the LPG, LNG, CNG or hydrogen fuel with the generator 130 and then To provide the necessary fuel.

Therefore, when LPG, CNG, LNG or hydrogen fuel is supplied, for example, when the crankshaft is rotated by the compression and explosion stroke of a two-cylinder engine, a rotor of the generator 130 may rotate to generate electricity for charging. do. This embodiment is an LPG taxi and a CNG bus, except that the engine is only used to turn the generator 130.

In addition, in the case of using the rotational energy transmitted from the wheel, for example, the generator merge charger 100 is mounted on an electric vehicle (or a hybrid vehicle), the rotor provided in the generator 130 is connected to the rotating shaft of the wheel In this case, the generator 130 is operated by the rotational force transmitted from the wheel at the time of the other road running with only the acceleration force without stepping on the accelerator of the vehicle or when the brake is pressed to generate electricity for charging. That is, in the case of traveling on a vehicle, the wasted energy is reused as a power source of the generator 130.

The controller 160 controls the charging of the battery B through the charger or the generator 130. Specifically, the controller B may be charged using the general charger 110 or the rapid charger 120. Allow the battery B to be charged, or allow the battery B to be charged through the generator 130, or merge two or more of them (for example, using the rapid charger 120 and the generator 130 simultaneously). Control to charge the battery (B).

The charging control is basically any one of the battery B, the general charger 110, the rapid charger 120, or the generator 130 through switching switching of a supply line in which power supplied or generated power is supplied to the battery B. This can be easily done by selecting the connection of. In FIG. 3, one of the charging control methods of the controller 160 is to control the charging of the battery B using the rapid charger 120 to be intermittently performed by the on / off of the supply switch 121.

Of course, as described above, the switching may be switched to connect two or more of the general charger 110, the quick charger 120, or the generator 130 to the battery B at the same time.

In addition, in the process of rapidly charging the battery B by using the voltage balance between the quick charger 120 and the battery B, the controller 160 balances the charging capacity of the quick charger 120 and the battery B. It includes a PID proportional gain control function to detect when 50%: 50% is balanced or 100%: 100% balanced by continuous charging.

Therefore, the execution value when the closest charging state value (for example, the charge capacity error between the quick charger 120 and the battery B is close to 0.1%) is calculated to recognize the closed loop scanning value, The blue light is turned on through the same display unit 40a to display "full charge", thereby generating a signal of "stabilized", thereby performing a function as a stabilization unit. Indication of full charge is possible through the flashing light 161 as shown in FIG.

The charge monitoring unit 140 monitors the state of charge of the rapid charger 120 made of a large capacity capacitor and the battery B, which is the secondary battery, and the monitoring terminals are respectively connected to both electrodes of the rapid charger 120 and the battery B. The terminal, which is connected and outputs the monitoring result, is connected to the controller 160 to transmit the state of charge of the rapid charger 120 and the battery B to the controller 160.

Therefore, when the charging capacity of the rapid charger 120 made of a large capacity capacitor exceeds 800 Ah, for example, the charge monitoring unit 140 detects this and notifies the controller 160 so that the rapid charger 120 is not overcharged.

Of course, the battery B may be controlled to prevent overcharging by referring to the reference value (depending on the reference capacity of the battery B) set in consideration of the charging capacity of the battery B.

On the contrary, when the charging capacity of the quick charger 120 is 20 Ah or less, for example, by operating the generator 130 or the general charger 110 to charge the rapid charger 120, the rapid charger 120 is always appropriate size. To be charged. Therefore, the battery B may be rapidly charged by using the quick charger 120 when the battery B is discharged.

Of course, when the charge capacity of the battery (B) is below the reference value, the generator 130, the general charger 110, or the rapid charger 120 to operate the battery (B) to be charged.

The program memory 150 stores programs or reference values used for various controls in the controller 160. In this case, reference values for stopping the charging of the rapid charger 120 are used as reference values (eg, 800 Ah, overcharge protection). Set value) or a reference value (eg, 20 Ah, over-discharge prevention set value) for starting charging of the rapid charger 120, and the program includes various applications required for operating the generator-merge charger 100 of the present invention. Include the program.

On the other hand, the generator 130 merge charger 100 according to the present invention as described above, may be configured as a circuit as shown in FIG.

That is, the present invention includes a general charger 110, a rapid charger 120 made of a large capacity capacitor (C1), a generator 130 and a controller 160, which are connected to the battery (B). In addition, a constant current supply device 122 is provided between the large capacity capacitor C1 and the battery B, which are the rapid charger 120.

At this time, the general charger 110 is configured to include a transformer (T1) and a rectifying bridge diode (BD) for transforming the commercial power supplied from the outside through the charging power connection plug 112, and is output through this The positive electrodes are connected to the positive electrodes of the battery B so as to supply the electrostatic source to the battery B, respectively.

In addition, not only the output terminal of the generator 130, but also the large-capacity capacitor C1 constituting the rapid charger 120, both of the electrodes are connected to both electrodes of the battery B, so that the battery output from these Allow (B) to charge.

In addition, the constant current supply device 122 includes two Darlington transistors Q1 and Q2 connected in series, a variable resistor VR1 and a distribution resistor R1 connected in parallel to each other. According to the magnitude of the power input to the base terminal of the Darlington transistor Q2, the current supplied to the battery B is constantly constant by interrupting the current flowing through the emitter and the collector stage of the second Darlington transistor Q1. To lose.

As described above, the present invention differentiates the charger 110 and 120 and the generator 130 from the prior art so that they can be charged at a normal speed or rapidly charged when they are moving or stopped through them.

In particular, the present invention is environmentally friendly because LPG, LNG, hydrogen fuel without the generation of low carbon can be used as the fuel of the generator 130 which is the main part.

In other words, LPG is protected by the government as a fuel for ordinary people at the price of 100 diesel, and is applied to a variety of vehicles from taxi, handicapped and car rental to general use. It is a trend that is applied to prevent the smoke of LNG city bus, and is a fuel that is getting a good response to the global green movement, hydrogen is a fuel that is spotlighted as the future energy because only water is discharged, not soot as an alternative fuel, in the present invention Since 130 may be driven using such green energy, it may be referred to as an environmentally friendly product that contributes to preventing environmental pollution and preventing global warming.

In addition, the effect of LPG fuel compared to diesel is 100: 50 in terms of price. For example, if the diesel price is 1600 won per liter, LPG is 800 won, resulting in a 50% reduction in fuel costs and the effect of LNG fuel. As it is a quarter price of diesel, it is 400 won per liter and the calorie is 30000kcal when LNG is 10000kcal, so it can run three times more mileage than diesel, and hydrogen is one-tenth the price of diesel. Because it is 160 won per liter and the heat is 34158kcal, it is effective to run 3.4 times the mileage compared to diesel.

On the other hand, the electromagnetic shielding shield (S), which has not been described in detail above, is formed in a partition shape so as to block between the chargers 110 and 120 and the generator 130, and various materials having a shielding effect of a conductive or non-conductive material are used. As a result, electromagnetic noise generated when the generator 130 is operated is prevented from affecting the charging current of the chargers 110 and 120.

In addition, the vibration absorber (P, C) is provided between the charger (110, 120) and the generator 130, the mechanical noise generated during the operation of the generator, that is, vibration is transmitted to the charger (110, 120) to reduce the charging characteristics or Prevents the charger from deteriorating its durability.

Such a vibration absorber (P, C) may be made of a structure in which a plate-like spring (C) is interposed between a pair of support plates (P), as shown as an example, plate-shaped between the other pair of support plates (P) Various vibration absorbers may be used, including a structure having a plurality of coiled springs instead of the springs (C).
