Advantages

Automated Meter Reader (AMR)

  • Broken passivation layer on lithium surface increases high leakage current, leading to battery exhaustion after 5-7 years.
  • Low performance in low temperature environment.
  • Coupling Cellergy Super-capacitor in parallel to battery.
  • Connect Supercapacitor to the load only during discharge.
  • Extends battery life
  • Allows proper devices functioning.

LED Flash

  • Short battery lifespan and underperformance of LED flash devices.
  • Coupling Cellergy Supercapacitor in parallel to battery.
  • Increases battery life.
  • Higher light output (brighter).

GSM/GPRS

PCCards

  • Typical GSM/GPRS transmitters exceed allowed current draw. As a result of internal resistance of supply lines, low output voltage is created.
  • Add Cellergy Supercapacitor in parallel to the power supply line.
  • Allows 2A current pulse necessary for proper performance.

Battery Operated Active RFID Tag

  • During transmission, high battery’s internal resistance causes high voltage drop, causing packet transmission disruption.
  • Add Cellergy Super-capacitor in parallel to Lithium battery.
  • Connect Cellergy Super-capacitor to the load only during discharge.
  • Extends battery lifetime.
  • Decreases voltage drop.

Solenoid

  • In many electro-mechanical devices, 2-3A peak current required. Typical Lithium battery not able to supply this.
  • Add Cellergy Super-capacitor in parallel to Lithium battery.
  • Allows necessary 2-3A peak current.
  • Decreases voltage drop.

USB Powered Devices

  • Audio power and quality degradation.
  • Add Cellergy Super-capacitor in parallel to USB Voltage.
  • Connect Cellergy Super-capacitor to the load only during discharge.
  • Causes an increase in peak power, leading to audio quality and power to improve.
  • Decreases voltage drop on USB port.

Energy Harvesting / Wireless Sensor Networks (WSN)

  • Batteries limited: constant recharging, frequent replacement, environmental concerns.
  • Replace battery with Cellergy Super-capacitor.
  • Buffers high power load from low power source.
  • Quick charging.
  • Continuously saves energy.
