Mesha, Inc. has developed the Mesha Integrated Storage Technology (MIST) that consists of the following components:

  • Hybrid UltraCapacitor (HUC)
  • Battery (Lead Acid or Li-Ion)
  • Energy Management System (EMS)

The MIST technology is the first of its kind in the marketplace that addresses the requirements of the users in the off grid marketplace. It brings the following benefits:

  • Leverages and smoothens the load requirements
  • Improves overall efficiency of the system
  • Extends life of the battery
  • Quick charging capability (under variable weather conditions) makes more usable watts available for daytime applications

Mesha has developed the Mesha Integrated Storage Technology (MIST) that consists of the following components:

Hybrid UltraCapacitor (HUC)
Battery (Lead Acid or Li-Ion)
Energy Management System (EMS)

  • Hybrid UltraCapacitor (HUC) - The HUC is a form of super-capacitor combining faradic and non-faradic elements.t The cathode or positive side is similar to a lead acid battery. The negative or anode side is similar to an Electric Double Layer Capacitor (EDLC). HUCs offer the following advantages over traditional batteries

    •    Higher power density
    •    Quick charge and discharge times
    •    Higher charge currents
    •    Longer life (more than 100,000 cycles)
    •    Low capacity units which can deliver high discharge currents thereby reducing the size of the units

The HUC technology has been patented in the following regions:

  • USA - Two patents
  • Japan - One patent
  • South Korea - One patent
  • China - One patent
  • South Africa - Two patents
  • Australia - One patent and one is under review
  • EuroZone - Two patents under review
  • India - Two patents under review

 

  • Battery (Lead Acid or Li-Ion) - The batteries are commercially available.  Either of Lead Acid or Li-Ion battery is used with the HUC's to form a hybrid energy storage system. 
  • Energy Management System (EMS) - The EMS has Maximum Power Point Tracking (MPPT) along with the intelligence of charging and discharging of both Battery and HUC for different voltage levels. It has various protections like input and output short circuit, high temperature, over input voltage, over load, output low voltage and other protections as per the IS/IEC standards. The EMS software also supports various subsystems like Charging Algorithm (P&O technique), temperature compensation, discharging algorithm and user interface. The EMS software also has inbuilt communication facilities available through the USB port with a proprietary protocol.
