CHAdeMOSoftware

Software for Damien Maguire's CHAdeMO controller: https://github.com/damienmaguire/Chademo-Fast-Charge-Controller This code will help you add CHAdeMO DC fast charging to your EV, whether it is OEM or DIY.

Required hardware

• CHAdeMO connector
• 2x contactors
• Leaf VCU https://evbmw.com/index.php/evbmw-webshop/nissan-built-and-tested-boards/leaf-inverter-controller-fully-built-and-tested (new hardware is being designed and built, coming soon).
• Relay
• 1k pullup resistor
• Isabellenhutte IVT or IVT-S shunt

Required software

• This code
• SimpleISA library https://github.com/Isaac96/SimpleISA
• due_can library https://github.com/collin80/due_can
• due_wire library https://github.com/collin80/due_wire
• DueTimer library https://github.com/ivanseidel/DueTimer
• Wire_EEPROM library https://github.com/collin80/Wire_EEPROM

Notes

• There are a few configuration options in the software - press 'p' in the serial monitor to see them.
• I am open to adding support for different CAN-bus BMS systems, and possibly different voltage and current sensors. If you want something added please at least send me the entire protocol.
• The Leaf VCU requires a single modification to function correctly. Because its inputs are protected by voltage dividers, R17 (pulldown for IN2/D7) must be removed.
• If you don't have a Leaf VCU or don't want to dish out 300 euros, you can use a standard Due. You will need an M24M02 EEPROM, two open collector outputs, and two 12V-tolerant inputs, as well as dual CAN transceivers.

As of August 28, this code is in beta testing. In any case, use at your own risk - it is provided as-is.
