Statement of Work
Use existing autonomous controls of chargers
Implement optimized charge profiles Implement a GUI IAW 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
6
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 =>
GND P5 to J4P7
Data- P4 to J4P5Data+ P3 to J4P4
7
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

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
