We had our first IRC modules based on the G120 live in December
There is still allot of software development to do but all the needed functionality to get this project running is finished.
We developed a generic instruction set that’s interpreted at run time on a G120 based custom board.
In the current setup the IRC module is controlling all communication between the battery management system, the slow night charger (20Kw), the inductive charging system from Bombardier (140Kw), the main vehicle controller and the Siemens drive train.
At this stage storage, state machine, interpreter and redundancy, CAN communication, general IO, analog input and outputs and serial communication are implemented.
Next faze is IFU, Ethernet, wifi, Bluetooth and expansion from the instruction set.
In general, we are surprised about the stability of the G120 based board.
If you get it running and everything is tested as it should be done, the netmf proves to be a really stable platform
We did have “some” EMC problems but then again, if you charge a 35Kw battery in 8 minutes… and have choppers at 350amps and 650Volts…
