Applications for Ultracapacitors
Telecommunications
STC Ultracapacitors, celebrated for their reliable discharge performance, have gained considerable acclaim within the power industry, notably in power automation applications like Feeder Terminal Units (FTU). Their direct current (DC) power supply solution, known for its real-world efficiency, continues to garner increased industry understanding and recognition. Boasting ultra-low internal resistance, high power density, and a strong current output, these batteries offer dependable performance with a long cycle life of 20,000 charges and discharges, an impressive lifespan of 25 years, and a broad operating temperature range.
Additional features like rapid charging, compact size, light weight, easy installation, and maintenance-free operation further bolster their attractiveness. Additionally, these environmentally friendly batteries, made from safe, non-toxic materials and customizable to specific needs, demonstrate scalable potential. They provide reliable energy solutions for both on and off-grid applications, enduring drastic temperature differences, and making them suitable for electric power systems of all sizes.
Solar Street Lights
The solar LED street lighting system with STC Ultracapacitors is of high value in road lighting, forming a part of composite energy systems. This system, structured as displayed in Picture 1, comprises a photovoltaic battery array. The energy generated by the photovoltaic cell is first stored in the STC Ultracapacitors, which then supplies power to the battery via pulse or constant current when suitable. This process enhances the solar energy utilization rate and light comfort of the system, with the controller as the core component managing the energy transmission between various components.
UPS
Experience unparalleled reliability with STC Ultracapacitors, offering excellent performance across a range of applications including commercial, industrial, defense, humanitarian, automotive, and residential. Traditional storage batteries, such as lead-acid and Lithium-ion batteries, despite being popular choices for backup power supply systems, possess significant drawbacks including slow charge/discharge, high-current charging difficulties, complex maintenance, and limited temperature operation. Over time, these issues lead to a decline in capacity and power supply performance, highlighting the need for safer and more reliable energy storage systems. STC Ultracapacitors fill this gap effectively. They offer rapid charge/discharge, extended cycle life, high power density, superior low-temperature performance, efficient charge/discharge cycle, and a wide operating voltage range. They are also maintenance-free, eco-friendly, and provide higher quality and efficiency compared to traditional energy storage devices.
Marine Applications
In recent years, the global emphasis on environmental protection and reduction of harmful gas emissions has been intensifying, steering boat energy sources away from fossil fuels and towards low-carbon alternatives. As power battery technology continues to advance and costs decline, the push towards boat electrification grows stronger. As part of this trend, STC Ultracapacitors are being increasingly endorsed and implemented in marine applications.
AGV
With the rapid evolution of computer and information technology, AGV (Automated Guided Vehicle) smart cars have become integral to industrial sectors like transportation and warehousing, especially in the modern logistics industry where cost efficiency is paramount. In addressing the demand for automation, AGVs have become essential for flexible production lines and automated logistics systems. However, designing an effective power source for AGVs, which directly influences their functionality and size, has been a challenge. Conventional power sources such as lead-acid or lithium-ion batteries come with limitations. STC Ultracapacitors offer key benefits such as quick charging, wide temperature operation, long lifespan, energy efficiency, and environmental friendliness. They provide high capacity, lightweight, and the ability to be charged and discharged completely, making them an excellent choice for powering AGVs.
