  1. Design Review LSV2 Autonomous Chargers Design Team: (from the left) Branden Carpenter Wayne Romine Jon Stoker Dr. Hess (Advisor) Maggie Richardson

  2. Statement of Work • Use existing autonomous controls of chargers • Implement optimized charge profiles • Implement a GUIIAW previous profiles • Charging technician to monitor, but not expected to interfere with the charge

  3. What We Have Learned • RS 232/485 • Previous Attempts • Board Operations / Capabilities • SCPI (Standard Commands for Programmable Instruments) • Schematic • Board V. 5 • Components not installed on our version shown on interface chard layout graphic

  4. Serial Interface Card Layout Support For GPIB J4: RS- 232/485 No GPIB Header PWR Supply

  5. What We Have Accomplished • Purchased a serial communications board produced by MOXA • Determined the required connections to the charger’s interface card • Connected to an individual interface card that is used inside the chargers • Received a positive communications response • RS-485 => Data- P4 to J4P5 Data+ P3 to J4P4 GND P5 to J4P7

  6. Our Plan • Communicate with the chargers using the RS 485 or RS 232 ports on the ICS 4861 board currently installed within the chargers • Connect the ICS 4861 boards to the PC using a Moxa CP-118EL serial board • Create a simple GUI to convert the SCPI commands programmed into ICS 4861 board into an easily used touch screen program

  7. Specifications • Able to control chargers from single work station • Control includes (for two chargers): • Remote charger startup and shutdown • Query and display: • output current/voltage • Front panel indications • Ability to change output levels

  8. Diagrams • Wiring diagram Chargers Touch Screen PC MOXA Card Comm Cards

  9. Parts/Price List • MOXA CP-118EL • $378.13 • MOXA CBL-M68M9x8-100 • $53.50 • DB9 Cables • 50ft: $9.55*8 = $76.40 • 100ft: $21.99*8 = $175.92 • 0.100” Socket • 10pin: $0.39*10 = $3.90 • Termination Crimp: $4.13/50units • U of I Budget Number : KKK188 • Available Funds: $767 • Total Cost • $516.06 • $615.58 • Touchscreen • Screen: $556.87 • Mounting hardware: $144..05

  10. Planned Deliverables • Detailed installation instructions • All necessary parts for installation • Moxa CP-118EL serial board • Requires a PCI express slot on motherboard • Connection wires • Touch screen display unit • Software package to control the system

  11. Timeline • See Gantt Chart

  12. Future Works (Spring 2010) Code program with the ability to: • Configure 4861 board with network address. (Used for RS 485 multi-drop) • Manually send SPCI commands • Change voltage/voltage trigger • Change current/current trigger • Stop charger. • Query voltage and current from charger.
