A short circuit when the solar cell is connected will not affect the battery life of the animal

Battery short circuit, is a major manifestation of the internal damage of the battery, will cause a great impact on the use of the battery, but the impact of different batteries is not the same, short circuit will have the following impact on various batteries:

1. Dry battery, because the internal resistance of the universal battery is large and the energy is small, there will generally be no drastic phenomenon, for example: the appearance of the ordinary No. 5 short circuit can not see any change, when the time is a little longer, the battery will feel ambiguous and heated when touching the battery by hand. , which eventually leads to unusability.

2. Alkaline batteries or high-capacity batteries, this type of battery can see obvious sparks in the dark at the moment of short circuit, the current is larger than that of dry batteries, and the power cord will easily become hot, and finally cause the battery to heat up quickly, and then it is very hot, and a little longer may cause **.

3. Rechargeable battery. The internal resistance of this type of battery is very small, and if there is a short circuit, the consequences are quite serious. If two fully charged No. 5 rechargeable batteries are installed in the battery compartment and the positive and negative poles of the power supply are accidentally short-circuited, the current will immediately burn the power cord until it smokes and turns red.

Within a few seconds, the glue around the wire (which has a certain resistance) will melt. In the case that the wire is not blown, the battery will also heat up, hot hands and even**. If you choose a thicker power cord, the cord won't burn out, but the battery** is more likely.

4. The short-circuit phenomenon of lead-acid battery is mainly manifested in the following aspects:

1) The open-circuit voltage is low, and the closed-circuit voltage (discharge) reaches the termination voltage very quickly.

2) When the high current is discharged, the terminal voltage drops rapidly to zero.

3) When the circuit is open, the density of the electrolyte is very low, and the electrolyte will freeze in a low temperature environment.

4) When charging, the voltage rises very slowly and always keeps the value low (sometimes dropping to zero).

5) When charging, the electrolyte temperature rises very high and fast.

6) When charging, the electrolyte density rises slowly or almost non-changeably.

7) No bubbles or bubbling appears late when charging.

These are the consequences of short circuits in some commonly used batteries.

The solar cell is different from other power sources, it is a semiconductor, it has a great internal impedance, and after a short circuit, the solar cell returns to normal. Therefore, solar cells have short-circuit currents.

If it is only a short circuit for a short time, it will not have much impact. If it is short-circuited for a long time, it will affect the battery life and even damage the battery.

This one mainly depends on the type of battery, no.

It's not the same as a battery.

If it is charged with lead-acid, it will be fine, and if it is charged with high voltage for a long time, the life will be reduced.

Lithium battery has no memory effect, and shallow charging and shallow discharge will prolong the service life. However, it is best not to store at high pressure.

NiMH needs to be discharged and charged, and it is not necessary to charge and discharge repeatedly for a long time.

Therefore, it is better to use lithium battery for home systems. But as long as the lead-acid voltage is well controlled, there is no big problem.

The shallower the depth of cyclic discharge, the longer the battery life.

So it's best to charge when you have something to do.

"Doesn't it say that it's best to run out of batteries before flushing"This statement is seriously wrong.

Only nickel-cadmium batteries need to be recharged when they are used up.

Impact: Reasonable general configuration, 3-5 years lifespan.

It is recommended to use lithium batteries, which are not afraid of repeated charging, and can be fully utilized, and the charging current of lithium batteries is small.

If it is used to generate electricity, the short-circuit current will not change when the light intensity reaches a certain value.

If it is used for measurement, it is necessary to refer to the product manual, because the light intensity used is lower than that at constant output.

It cannot be short-circuited. Solar panel.

After the positive and negative connections, it will be short-circuited, it will ignite, and the smoke will likely burn the power supply. A single solar cell cannot be used as a power source directly. As a power supply, several single cells must be connected in series, in parallel and tightly packaged into components.

The light-heat-electricity conversion method uses solar radiation.

The generated heat energy is generally generated by a solar collector that converts the absorbed heat energy into steam from the working fluid, which is used to drive a steam turbine to generate electricity. The former process is the light-heat conversion process; The latter process is a heat-to-electricity conversion process, as is the case with ordinary thermal power generation.

There will be no short circuit during normal use.

When the solar cell is in use, the phenomenon of short circuit between the positive and negative poles will not occur if it is used normally. Solar cells are just like our ordinary batteries, in normal use, if there is a short circuit, it will cause the battery to overheat, or even **.

Solar cells make use of sunlight.

Optoelectronic semiconductor sheets that generate electricity directly. As long as it is illuminated by a certain illuminance condition, it can output voltage and generate current in the case of a loop. In physics, it is called solar photovoltaics.

Abbreviated as photovoltaics. <>

Of course, short circuits are not allowed. Just like our ordinary batteries, during normal use, if there is a short circuit, it will cause the battery to overheat, or even **.

When he is using the battery, sometimes the positive and negative poles will be short-circuited, and the connection is not good.

Electric energy batteries can be short-circuited when they are in use, and solar cells can be used according to different properties.

When this battery is in use, its positive and negative poles must be placed in the right place and must be placed correctly.

Can the positive and negative poles of Tianneng battery be short-circuited when in use? If these two exchanges are not good, it will definitely be short-circuited, so these two positive and negative poles must be separated, and there can be no connection between them, and if they are connected, there will definitely be some pain.

Open-circuit voltage and short-circuit current of the solar cell: open-circuit voltage UOC: The output voltage value of the solar cell when the solar cell is exposed to spectral conditions and a light source intensity of 100 MW cm2, and the two ends are open-circuited.

Short-circuit current ISC: The current value of the solar cell flowing through both ends of the solar cell when it is exposed to a light source intensity of 100 MW cm2 under spectral conditions and short-circuited at the output end.

Features of solar cells:

Solar cells are also known as photovolt batteries, referred to as photocells. It is a device that directly converts the light energy of the sun or other light sources into electrical energy. As long as it is illuminated by a certain illuminance condition, it can instantly output voltage and generate current in the case of a loop.

In physics, it is called solar photovoltaic (photovoltaic, abbreviated as PV), referred to as photovoltaic. The solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. Crystalline silicon solar cells working with photoelectric effects are the mainstream, while thin-film cells working with photochemical effects are still in their infancy.

Solar cell power generation is a renewable and environmentally friendly power generation method, which has the characteristics of light weight and safe use. No greenhouse gases such as carbon dioxide are produced during power generation, and no pollution will be caused to the environment. In the current world energy shortage and environmental protection situation is becoming increasingly severe, people have high hopes for solar cells, solar cells are likely to become an important part of the future of electricity.

At the same time, solar cells also play a very important role in modern detection and control technology, and are used as a power source in satellites and spacecraft. <>

Summary. The short-circuit current of the solar cell is in the sun. license in the case of his.

The maximum current when the output is short-circuited to the positive and negative terminals. Its current is related to the internal resistance of the solar panel. Therefore, at this time, it depends on how big the internal resistance of the solar cell is, the current of his circuit determines the open circuit, and the voltage is when there is no output.

And for rechargeable batteries, etc. The opening voltage that cannot be connected to the voltage is not connected to the electrical appliance, and its maximum voltage at this time is.

Solar cells are short-circuited, and under light conditions, of course, they are also called short circuits, and electrical energy is converted into thermal energy. There is a term in the photovoltaic industry called the hot spot effect.

The voltage remains the same, the current increases, remember that the battery voltage on each branch remains the same, the current increases, remember that the battery board on each branch should be the type to talk about the Pei Repentance, and the number is the same; The positive electrode is connected to the negative electrode, which belongs to the type of string plate, and the number is the same; The positive electrode is connected with the negative electrode, which belongs to series connection, the current remains unchanged, the voltage increases, and the positive note is the same - - on the branch, each link, the current remains unchanged, the voltage increases, remember that the same - on the branch, the power of each solar panel is the same, the model is the same, the power of the solar panel is the same, the model is the same

Solar panels repeatedly charge the battery does not affect the life of the battery, hello dear, the battery can not be overdischarged, or overcharged your battery is overdischarged, you must first check that the electrolyte in the battery can not be less than the limit, that should be used to activate the battery, metaphor 12 can be used old-fashioned manual charging, can not use the ordinary intelligent charger, some old rock-eliminating (there is a transformer of the ordinary rectification and the voltage is in the 12V battery, you can use 18V to activate (note that the battery, When the voltage is normal to 12V, use 12V smart charging, so that it will not overcharge and the ridge bridge will damage the battery. The minimum battery voltage can not be overcharged, and 12V can be used 18V solar energy, and he peaks up to 21V You must install a solar energy resistor to avoid overcharging and overdischarging.

Summary. When not in use, such as at night or when not in use for a long time, you can disconnect the battery cord inside. Distributed solar power generation systems are equipped with lightning protection devices, so it is also possible to disconnect the circuit breaker switch of the combiner box for safety, cut off the circuit connection with the solar cell module, and avoid the harm caused by direct lightning.
