Hytech Racing Project Notes and Status

Electrical Systems Current Status:

• CAN Bus
• Function in loopback mode
• Error during bus communication (most likely due to transmission identification)
• Pedal Node
• Both accelerator pots tested and working
• Both brake pots giving bad values
• Serial communication confirmed
• Engine Node
• Function voltage divider and servo control code for maintaining lower nominal voltages.
• Racing error when approaching 72V. I think this is because the voltage curve non-linear. Possible fix, larger resolution with custom gearbox.
• IMPORTANT: need to remove common bus between 12V and 72V line
• Motor Node
• Further testing needed for successful RS232 communication with Kelly Controllers
• Battery Node
• Need battery protocol
• Display/Safety Node
• Successful serial communication
• Successful LCD output
• Low power schematic and functional circuit defined

**NOTE: Serial communication is not the same as CAN Bus communication

Electrical Systems Add-ons: 

• Display/Safety Node
• Netbook or old Android Phone: 
• Large full color GUI with live monitoring
• Computationally powerful and WIFI enabled.
• Would allow real time network communication over WAN
• GPS enabled
• Client/Server Application
• Allow real time monitoring/tweaking
• Real time analysis and graphing
