Key Features

UCR Series : High-Cycle Supercapacitor Cells

The UCR Series represents Ecosense's entry point into industrial supercapacitor cells. Built on carbon-carbon double-layer capacitor chemistry, these cells are engineered specifically for transportation and pulse power applications where cycle life and thermal stability are non-negotiable. The UCR27V3000B operates across a voltage window of 0 to 2.7V, delivers up to 2200A peak current, and holds its charge characteristics over one million cycles at reduced voltage depth (1.35V to 2.7V). Its wide operating temperature range of -40°C to +65°C makes it suitable for outdoor rail vehicles operating in both northern winters and tropical summers.

Frequently Asked Questions

A supercapacitor is an advanced energy storage device that stores electrical energy electrostatically rather than through chemical reactions. This enables extremely fast charging and discharging while maintaining excellent efficiency and long service life. Supercapacitors are designed for high-power applications where rapid energy delivery, regenerative energy capture, and frequent cycling are required. They are commonly used alongside batteries to improve overall system performance and reliability.

The primary difference lies in power delivery and cycle life. Lithium-ion batteries are optimized for storing large amounts of energy, while supercapacitors are designed to deliver and absorb power very quickly. Supercapacitors can be charged in seconds and can withstand hundreds of thousands of cycles with minimal degradation. In many applications, they complement batteries by handling peak power demands and reducing stress on the battery pack.

Supercapacitors are widely used in transportation, renewable energy, industrial automation, smart grids, logistics, and backup power systems. Typical applications include electric buses, trams, railways, automated guided vehicles (AGVs), cranes, wind turbines, solar energy systems, and industrial machinery. Their ability to provide high burst power and recover braking energy makes them particularly valuable in electrified transportation and energy management systems.

Yes. Supercapacitors are frequently integrated with battery systems to create hybrid energy storage solutions. In such configurations, the supercapacitor handles sudden power demands and regenerative energy capture, while the battery provides sustained energy. This approach improves system efficiency, reduces battery stress, extends battery lifespan, and enhances overall performance in electric vehicles, renewable energy installations, and industrial power applications.

Depending on operating conditions and application requirements, industrial-grade supercapacitors can achieve more than 500,000 to 1,000,000 charge-discharge cycles. Unlike conventional batteries, they experience very little performance degradation over time. Their long operational life significantly reduces replacement costs and maintenance requirements, making them a cost-effective solution for applications involving frequent cycling, high power demand, and continuous operation.

Yes. Supercapacitors are increasingly used in electric buses, hybrid vehicles, trams, and rail transportation systems. They are particularly effective for regenerative braking energy recovery, acceleration assistance, and peak power support. By rapidly absorbing and delivering energy, they improve vehicle efficiency, reduce battery loading, and extend battery life. Many modern public transportation systems use supercapacitor technology to enhance overall energy management.

Industrial supercapacitors are designed to operate reliably across a wide temperature range, typically from -40°C to +65°C. This makes them suitable for demanding environments where conventional batteries may experience performance limitations. Their ability to function efficiently in extreme temperatures makes them ideal for outdoor infrastructure, transportation systems, renewable energy installations, and industrial applications exposed to varying climatic conditions.

Selecting the appropriate supercapacitor depends on factors such as voltage, capacitance, power requirements, charge-discharge frequency, operating environment, and system integration needs. Ecosense provides technical consultation to evaluate application requirements and recommend suitable products. Our team assists with system sizing, module selection, thermal considerations, communication interfaces, and performance optimization to ensure reliable and efficient operation.
