Supercapacitor Lithium-Ion Battery Hybrid Electric Vehicle (HEV) Research Background

Objective Develop an energy storage system that is suitable for Hybrid Electric Vehicles (HEV) and renewable energy storage systems Develop an energy storage system that is suitable for Hybrid Electric Vehicles (HEV) and renewable energy storage systems Use active circuit components and a microcontroller to maximize the efficiency of the hybrid battery-super capacitor combination Use active circuit components and a microcontroller to maximize the efficiency of the hybrid battery-super capacitor combination SizeCostWeight

Project scope For safety reasons this design will be a smaller scale test model of systems used in HEV and renewable storage systems. A 1KW pulsating load will be used to simulate energy demand Super- capacitors With high power density, super capacitors are the perfect complement to rechargeable batteries. Super capacitors are used as a buffer between the battery and a load. Our load will receive pulse power from the super-capacitors Load Pulsating load with 48 volts + 20%, one kilowatt peak power for 18 seconds over every 2 minutes( almost zero kilowatts for the remaining 102 seconds of every 2 minute period). A microcontroller will be used to send feedback to the battery- super capacitor system from that load. That feedback will be energy demand at every instance in time. Design Specifications
