In addition, by providing an independent power supply 67 to selectively apply a voltage or a current to the piezoelectric plate 65 so as to be independent of the power supply function of the battery 60 itself, there is a problem in the function of the battery 60. In this case, the sulfate removal function can be performed.

2 is a view showing the configuration of the electric bicycle 100 using the sulfate removal device according to the present invention. As shown in Figure 2, the electric bicycle 100 according to the present invention, a solar cell module including a plurality of solar cells arranged on the front surface of the bicycle (100); A battery 60 for accumulating electrical energy obtained from the module; A motor driving unit selectively connected to and driven by the rear wheel 80 of the bicycle 100 through the power of the battery 60; A piezoelectric plate 65 oscillating the electrode plates 61 and 63 of the battery 60; And an independent power source 67 for supplying power to the piezoelectric plate 65.

The motor driving unit is connected to the rear wheel 80 of the drive unit 100 and supplies power to the piezoelectric plate 65 and the piezoelectric plate 65 which vibrate the electrodes 61 and 63 of the battery 60. Independent power supply 67 is provided.

In addition, the handle (60) for the user's convenience and safety provided in the general bicycle (100), the support on which the user can sit, the front and rear two-wheel drive wheel 80, and the two-wheel drive wheel ( 80) is provided with a pedal for transmitting power manually through the user's foot. In addition, through the pedal to drive the generator mounted on the rear cradle of the bicycle 100, it is possible to charge the driven power to the battery 60.

As such, the present invention absorbs sunlight through the solar cell module 10, converts it into electricity, charges the battery 60, and drives the motor driving unit through the charged battery 60 to drive the wheel of the bicycle 100. It has a basic structure for driving 80. In addition, the present invention further includes a device for removing sulfate formed on the plates of the electrodes 61 and 63 of the battery 60. The removal device of the present invention includes the electrodes 61 and 63 as shown in FIG. A piezoelectric plate 65 is attached to each back side of the plate, and the piezoelectric plate 65 and the independent power source 67 are connected to each other with a conductive wire to selectively vibrate to form sulfates, which are milky crystals formed on the electrodes 61 and 63 plates. Will be removed.

Here, the independent power source 67 may be another battery 60, or may be formed through the solar cell module, but the rotational kinetic energy of the wheel 80 generated when driving the bicycle 100. It is preferable that it is a self-generating part 67 for use.

When the user drives the bicycle 100 as described above, the voltage or current applied from the self-power generation unit or the independent power source 67 is transferred to the piezoelectric plates 65 attached to the electrodes 61 and 63 plates of the battery 60. By applying and vibrating, the milky-crystal (sulphate) which adhered to the said electrodes 61 and 63 boards is dropped and removed.

There is an advantage to increase the efficiency.

3 is a view showing a control block diagram of a bicycle 100 according to the present invention, Figure 4 is a view showing a flow chart of the control method of the bicycle 100 according to the present invention. First, looking at the configuration of the solar cell module 10 used in the present invention, in a form similar to a conventional solar cell module, by arranging a plurality of solar cells in the form of a light collecting plate to easily absorb even minute sunlight photovoltaic power By effect is configured to generate electrical energy.

Specifications of the solar cell module 10 will depend on the capacity of the applied product, the purpose of use and the purpose of charging. In this case, the purpose of use may be divided into charging only, stabilizing only, charging and stabilizing simultaneously, and charging purposes may be classified as starting for natural discharge compensation or starting with the main charging device. Can be.

Therefore, the characteristic specifications of the solar cell module can be specified by appropriately adjusting according to the situation and environment. The biggest feature of the solar cell module 10 used in the present invention is that if the solar output voltage is lower than the minimum input voltage even though the solar output voltage is lower than the rated voltage of the battery 60 is sufficiently charged even when the incident amount of sunlight is fine. It is configured to generate the required voltage, and by supplying surplus voltage higher than the nominal voltage efficiently to the battery 60 at a time when solar incident rate is relatively low, it is possible to maximize energy efficiency and charging efficiency. It is manufactured in a form that can be attached to or detached from the vehicle body, and can be selectively used according to the environment used.

On the other hand, looking at the configuration of the booster 20, it has a configuration to boost the relatively low output voltage obtained in the solar cell module 10 above the rated voltage used for the general battery 60. By using the booster 20 as described above, a constant voltage can be maintained at all times even when the solar input voltage changes according to weather conditions and time zones, and as a result, a low output voltage is required for the solar cell module 10, resulting in solar cells. When manufacturing the module 10, it is possible to minimize the cell loss (Cell Loss) portion is configured to improve the mass production.

In addition, the voltage boosted through the boosting unit 20 is configured to be supplied to the battery 60 through the charging unit 30 to charge the battery 60, the charging unit 30 is the overcharge and over-discharge protection unit ( 31 and the battery 60, the smart charging display unit 32.

The charging unit 30 is basically configured to charge the battery 60 with the voltage supplied from the boosting unit 20, and this charging function keeps the battery 60 in a fully charged state only when it is not started during the day.

Since the power supply is smooth when the day and night start or daytime is not started, there are no restrictions on the operation, but when the power is not started at night, the power supply is limited. To solve this problem, the battery 60 The problem can be solved by receiving fine power from the battery, and the power supplied from the battery 60 is configured to not follow the discharge constraint because an extremely small level of power of about 1/40000 of the rated capacity is required.

The stabilization pulse generator 41 has a configuration in which a separate stabilization display unit 42 is provided to visually check the stabilization state of the battery 60. Finally, looking at the configuration of the microcomputer 50, it is configured to control the operation of the charging unit 30 and the feedback stabilization circuit unit 40 by sensing the voltage obtained from the solar cell module 10 and the boosting unit 20, the conventional It is a kind of non-memory semiconductor similar to MCU (Micro Controller Unit) used to control various characteristics of the product.

Looking at the operation of the present invention configured as described above, Note? When divided into night start and non-starting, first, during the daytime non-starting operation, when the solar light is incident on the solar cell module 10 is converted into 4V electrical energy by the photovoltaic effect and supplied to the booster 20 As the voltage is increased, the voltage is increased to 24V and then supplied to the battery 60 to maintain the state of charge up to the nominal voltage, and the battery 60 is stabilized through the feedback stabilization circuit 40. Works to perform.

On the other hand, the operation process during the daytime start and nighttime, to be charged using the power supplied from the generator mounted on the vehicle, and stabilized by the feedback stabilization circuit unit 40 using the power supplied from the battery 60 It is operated to perform a function.

Lastly, the operation process during the night non-starting is not supplied with power from the battery 60 and the sunlight, so the charging function is not performed and is supplied from the battery 60 and stabilized through the feedback stabilization circuit unit 40. Only function is activated.

As described above, the bicycle 100 according to the present invention proposes a configuration including a removing device for removing sulfate that degrades the performance of the battery 60 and a stabilizing device, thereby applying an electrical signal to the electrodes 61 and 63. By removing the sulphate in parallel with the physical method of applying vibration to the plates of the electrodes 61 and 63 by using the method and the self-generating unit, it is possible to provide the battery 60 with high efficiency. In addition, by controlling the driving system or the solar cell module according to the driving state of the bicycle 100, it is possible to perform a stabilization function of the bicycle 100 driving system or the battery 60.
