VIII. (Intermediate) power system
Abstract
- SJSU EE’s have created a solar power interface system to supply power to Superway/utilize solar energy
Introduction
- Two mains objectives:
i. Replace batteries for 1/12 scale w/ solar cells + conducting wayside system
ii. Create solar interface system to provide power to intermediate scale model
- We are going to make history
Technological Impact and Uniqueness of Spartan Superway
- Pollution by cars climbing dramatically
- Superway here to help
Project Specifications and Methodology
- 2 different scales of SMSSV were planned for production, a 1:12 scale model and an intermediate scale model
- 1/12th scale
i. Employs multiple pod car batteries
ii. Each pod car has a motor, a series of servos, a microcontroller, and a backup battery
iii. Energized using 3rd rail system
iv. All battery system being used instead
- Intermediate
i. Commercial off the shelf design used
Project details
- System converts captured solar energy to U.S grid compatible AC power
- AC will power another multiple-output power supply
- An array of 15 solar panels provide approximately 1 kW of peak power to a grid-tie inverter
- Connected to utility source is a battery charger
- Nominal 48VDC on the wayside rail will power the drive motor controller and a second 1500W inverter unit
Costs
- Estimated cost is $1128.63
Completed and Current Goals of the Team
- Production of 1/12th scale solar interface terminated at start of spring semester
Team Management and Performance
- Team was highly effective and adaptable
- Team involved in larger superway meetings
- Group email was used as primary medium of communication
Major Challenges Faced
- Lack of data needed to move forward with project
Conclusion
- Things went very well
- All hail the superway!!!
