Application of supercapacitor combined with battery in solar powered equipment

The energy storage characteristics of the physical process of supercapacitors determine that their combination with batteries has a natural application advantage in solar energy, absorbing weak and unstable solar energy that batteries cannot absorb in the morning, evening, rainy days, etc. Thus enabling
Maintaining more electrical energy in the battery, in terms of the characteristics of battery life maintenance, protects the battery, extends its service life, enhances the stability of the entire solar energy system, and achieves the goal of energy conservation and environmental protection.
The two main reasons why batteries are prone to damage are high current discharge and discharge when there is insufficient electrical energy. The solar powered equipment used in the wild usually has the following phenomena due to insufficient electricity. Due to changes in natural temperature, there is usually a decrease in battery discharge capacity; Due to climate change and geographical factors such as cloudy, rainy, snowy, sunny, partly cloudy, and north-south sunlight, there is usually a shortage of battery power.

Principle of combination of supercapacitor and battery

By utilizing the characteristic of supercapacitors that can absorb weak currents, when the current generated by the solar panel is not large enough, the supercapacitor is first charged, and then the electrical energy in the supercapacitor is controlled to be stably charged into the battery. By replenishing the energy that the battery cannot absorb into the battery, it ensures that the battery has sufficient power to provide for device use, thereby ensuring the lifespan of the battery and achieving the goal of ensuring the stability of the solar energy system.
Application of pure supercapacitors in solar powered equipment
The energy storage characteristics of the physical process of supercapacitors determine that their combination with batteries has natural application advantages in solar energy, absorbing all the electrical energy generated by solar panels and achieving the true goal of energy conservation and environmental protection.
