Hello, can't the current from the solar panel pass through the booster chip? But lithium batter

The voltage of the solar panel can be increased by a booster chip. In practical applications, because the voltage of solar panels changes greatly with the intensity of light and the current of solar panels is generally small, batteries are usually used to store electrical energy first, and then a chip boost is used to increase the voltage. we need. .

What is your battery voltage?

It's very complicated

First of all, we need to consider the adequacy of the voltages of the two. If the voltages match, then under the ideal light intensity, an output of 3v200mA can be. reached, and the charging time is 1000mAh/ 200mA*1.2~1.4=5h~7h if the conditions are good - like in a desert area - it's better than nothing!

If the voltages do not match, this can in principle be achieved with a power conversion booster (the form ddepends on the nature of the load), but there is a problem: the power of the two is too unsuitable, and the power conversion must be taken into account. The loss of power is even more unsuitable. In addition, the solar panel only has an output of 3v200mA under ideal light intensity, which may be reduced in actual use.

Note that the power conversion booster mentioned above does not only refer to transformers. Direct current cannot produce an alternating magnetic field in the coil, so the secondary side of the transformer cannot produce induced current. However, if the DC power supply is transformed into a DC pulse form via components such as field effect transistors and corresponding circuits (the operating principle of a switching power supply), another pulse voltage increased or decreased can be obtained depending on the transformation ratio of the botransformer bine (the same principle applies to electric batons), then the pulse voltage is rectified and filtered back to direct current. The voltage can be designed according to your needs.

The above conversion circuit requires a power supply to ensure the stable operation of the converter components, because each chip (including many transistors) requires a certain voltage and current to operate. It looks like your solar panel is not working. be able to provide a stable power supply as well!

Judging from the characteristics of your diet, it seems that it can't handle this torment!

It's difficult!

If you have a mobile platform such as driving a car, you may want to configure 2-3 solar panels (determined by the voltage of your battery to charge) (plus the voltage of adaptation ofthe rectifier diode if necessary) charge in series and avoid boost devices.
