Question 1 The voltage measured when connected to the solar cell is the charging voltage, which indicates that it is charging, and this voltage increases as the battery voltage increases.
If you measure the current, it means that the charging current is 200mA
When the charging time is longer, the higher the voltage will be, and the highest will be about it.
Question 2 For lithium batteries, there is a charge protector on one board, and the voltage is controlled within it.
Therefore, you don't need to consider this to directly charge the lithium battery, you can directly add a diode, and if you use a bare lithium battery, you need to simply design the following circuit.
Q3 Voltage Shutdown? This is to be protected, the voltage of the solar panel is much higher than that of the AA battery, and it is necessary to make an anti-overcharge.
Question 4 This does not affect the charging effect, it may actually be better, the role of the controller is mainly to protect the battery.
Question 5 Positive and negative negative.
-
Question 2: How to make a simple voltage limiting circuit to control the battery not to overcharge (the simpler the better)? Pressure limiting.
Question 3: Is it possible for this solar panel to charge 4 AA batteries directly and stop charging through voltage?
Question 4: Will the charging efficiency be reduced if the solar panel directly recharges the battery without step-down management and only relies on the load to pull down the voltage?
Question 5: If you directly use solar panels to recharge the battery, how to connect the electrodes is reasonable, whether it is positive and negative or reverse (positive and negative.
-
If the battery is directly rechargeable with solar panels, it is reasonable for the electrodes to be positive and negative to negative.
-
To connect a diode output to prevent backflow to the battery at night.

It should be noted that the Taineng battery is a current-type device, usually the output voltage of a battery is limited, and multiple pieces are required to be connected in series, because the output current of each battery is different in different situations, resulting in the current after series connection is not the best state, but parallel connection can avoid this situation, and the different currents are collected together with the highest efficiency. If one of them fails, it will not affect the other panels.
Solar cells, also known as "solar chips" or "photocells", are thin sheets of optoelectronic semiconductors that use sunlight to generate electricity directly. As soon as it is exposed to light, it can output voltage instantaneously and generate current in the case of a loop. In physics, it is called solar photovoltaic (photovoltaic, photolight, voltaics volt, abbreviated as PV), referred to as photovoltaic.
A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. Thin-film solar cells that work with photoelectric effects are the mainstream, while solar cells that work with photochemical effects are still in their infancy.

1. Lithium batteries can be charged with solar chargers.
1. The power provided by the solar panel is a 'current-limited' power supply. The maximum charging power of the solar panel to the lithium battery is realized: when the total current required for the charging of the system and the battery exceeds the output current capacity of the solar panel, the system bus voltage near the MPP needs to be adjusted by reducing the charging current.
The key elements for designing a reliable solar panel-powered system are the system power and battery charge power control architecture.
2. Solar energy is the most attractive source of energy to power portable devices, however, the power provided by solar panels is highly dependent on the working environment, including factors such as light source density, light exposure time, and location. For this reason, batteries are often used as energy storage units. The battery is charged when there is enough power from the solar panels, and when the power provided by the solar panels is insufficient, the battery can power the system.
Battery charging systems require matching solar cell characteristics in order to extract maximum power from the solar cell more efficiently.
3. The core components of the solar charger are composed of solar cells and solar charge controllers, and the photosensitivity of solar cells is generally the entire visible light, whether it is sunlight or light. In fact, solar cells are just people's common name for this device, and the accurate name of this period should be "photosensitive cells" or "photocells", which are divided into silicon photocells and selenium photocells according to the manufacturing materials, and its principle is the photoelectric effect. The reason why it is called a photocell means that the device generates electrical energy under the condition of light.
Second, the advantages of solar chargers.
1. The solar charger does not need AC power supply in the sun, and directly converts sunlight energy into DC electricity. You can charge small electrical appliances such as mobile phones, digital cameras, power banks, and *** anytime and anywhere. It is a must-have companion for people who love to travel, frequent business travelers, outdoor sports people, and business workers.
2. The solar charger is a high-efficiency solar battery with a built-in energy storage lithium battery, which can be charged at leisure and used in an emergency. It is suitable for a variety of mobile phones and other electrical appliances. Completely eliminate the troubles of power shortage, power outage, and occasional battery running out for outdoor activities.
3. The solar charger charges quickly, and the mobile phone can be charged after 3 minutes of sunlight exposure when there is no electricity, and the mobile phone can be charged while the solar battery is charged in the sun.

Pro, the solar battery can be charged with a special charger, and the solar panel can also be used to charge the battery through the controller, 1The solar panel charges the battery, and the complete voltage of the two does not match and cannot be charged. All you need is a controller.
2.The working voltage of the solar panel is 35V, change the battery to 24V and then charge it with the 24V solar panel. If it is directly connected to the solar controller, it will not charge the battery, and the corresponding maximum voltage of the 12V battery is connected in series with a resistance in the wiring circuit to control the charging current, and the battery board, battery, current limiting resistor, and ammeter need to be connected in series.
Select the charging current according to the battery capacity, if the battery is 10VA, you can adjust the resistance size, control the charging current to the controller can detect the power generation voltage of the solar panel in real time, and track the highest voltage and current value (VI), so that the system can charge the battery with maximum power output. Applied to the solar photovoltaic system, it is the brain of the photovoltaic system to coordinate the work of solar panels, batteries and loads.

New energy vehicles can be solar charging. The proportion of electric energy used by new energy vehicles is less than 1 10 of new energy sources such as wind energy, solar energy, nuclear energy, etc., because the lack of energy storage has led to a lot of new energy generation being wasted, so electric vehicles are charged at night is also an auxiliary consumption of wasted electric energy, and direct electricity consumption is also a way to save energy and reduce emissions.
The use of solar energy in new energy vehicles to supplement energy saving models are mainly medium and large buses, the roof area of such cars is large enough and the model is unified can see obvious results, but the actual and adjust the peak and valley power consumption is somewhat contrary.
The installation of solar panels is calculated in terms of power, which is about 150 250 watts per square meter when converted into area, and the panels vary greatly depending on the technology. Taking the moderate 200 watt flexible solar panel as an example, one hour of normal sunshine is 200 watts without excluding conversion loss, and 10 hours of sunshine a day is only 2 kWh. This is only a theoretical value, the normal average sunshine is basically 6 7 hours, one square meter of power generation is only more than 1 kWh, and the battery pack capacity of new energy vehicles is between 40 and 80 degrees; The roof area that can be used by ordinary A0 class cars is only about 1 square meter, and it can only be fully charged once a month by relying only on solar panels to generate electricity, so the practicality is very average.
Only a large car with a roof area of more than 20 square meters such as a bus has a certain value, and this kind of car can make up about 1 10 of the capacity, while ordinary private cars can only do 1 40 1 80 or even less, and the actual effect is minimal.
There are some models of existing vehicles that use solar energy to replenish electricity, but most of them are fuel vehicles auxiliary lead-acid batteries that use in-car electrical appliances when parking, or RVs are used as supplements, even if the capacity of such cars is only seven or eight degrees, so there is still a certain significance, and there is no need to toss electric vehicles.
Therefore, there is no need to invest in the cost of installing solar panels that is not proportional to the return, and it is possible to charge normally, and the charging is best chosen at night, because it can assist in adjusting the peak and valley power consumption.
The proportion of electric energy used by new energy vehicles is less than 1 10 of new energy sources such as wind energy, solar energy, nuclear energy, etc., because the lack of energy storage has led to a lot of new energy generation being wasted, so electric vehicles are charged at night is also an auxiliary consumption of wasted electric energy, and direct electricity consumption is also a way to save energy and reduce emissions.

Solar panels do not charge the battery directly. Generally, solar panels charge batteries, there are protection circuits and charging circuits, that is, solar controllers have 12V, 24V, 48V, 20A, 30A. Controller Protection Circuit Function:
Battery overcharge, overdischarge, output overload, overvoltage, overtemperature protection function.
Charging is a Chinese word that refers to the process of replenishing power to a device such as a battery. The principle is to let the direct current pass in the opposite direction of the discharge, so that the active substances in the battery can resume their effects. It has extended meanings such as study, work, etc.
The working process of the battery receiving electrical energy from the external circuit and converting it into the chemical energy of the battery. After the energy of the battery is consumed by discharge, it can be restored by charging and can be re-discharged, constituting a charge-discharge cycle. Generally, it is charged with DC current (also with asymmetric AC current or pulse current).
In different cases, different charging methods are used, such as constant current charging, constant voltage charging, floating charging, trickle charging, emergency charging or a combination of these methods.
When the solar panel charges the battery, it is not possible to connect it directly, because the solar panel is greatly affected by the light, such as shadows and angles, so the output voltage is unstable and cannot be stabilized at 5V;
Generally speaking, it can be used with a mobile power bank that can output and input at the same time, and it is of course better if the solar panel itself has a built-in battery, but if the working voltage of your solar panel is about 18V, you can directly charge the 12V battery;
However, it is best to use a solar controller to prevent overcharging and reverse charging, protect the battery, if it is 24V or other voltage, the working voltage of the solar panel is more than 30% higher than the nominal voltage of the battery.
Solar panel is a device that responds to light and can convert light energy into electricity, and there are many kinds of materials that can produce photovoltaic effects, such as: Qinlao monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium, indium selenium, copper, etc.; The principle of their power generation is basically the same, and the process of light power generation is described by using crystalline silicon as an example. P-type crystalline silicon can be doped with phosphorus to obtain n-type silicon, forming a p-n junction.

Of course. The charging current of the 12V100 Ah battery should be 10A, you can connect the two boards in parallel, and then connect the positive and negative to the negative, and the light can be fully charged after about 10 hours.
In addition, the problem of whether to install the controller or not, is to see if you are not near the battery board power generation system, if you can use the controller at any time, if you are unguarded for a long time, just want to use it at night or the controller is better.
If you use it for three people, you can use a 58 pipe diameter, 18 pipes, 160 liters, or 20 pipes, 180 liters. >>>More
