For decades, the battery has been the preferred form of energy storage as it offered a high energy density (10~100 Wh/kg). However, limited by operating temperature (typically 0°C to 40°C) and cycle life (2 years or 500 charge-discharge cycles), the battery is neither rugged nor durable enough for industrial applications. Most importantly, the battery life is affected dramatically by ambient temperatures. Studies have shown, in general, at -5.5°C, a battery’s energy storage capacity may be reduced by approximately 50%.
And for battery lifecycle degradation, the first 200 charge/ recharge cycles operating in a 25°C environment, the battery is degraded by 3.3% while operating in a 45°C environment, the same 200 charge/ recharge cycle saw a 6.7% degradation. The degradation rate doubled at the higher operating temperature, and the rate continues to multiply with the rising temperature.
Unlike battery cells, the Neousys SuperCAP UPS are composed of ultracapacitors and can operate in wide temperature environments from -25 to 65°C. They offer industrial-grade reliability and are highly durable lasting over 10 years while operating in demanding industrial conditions.
