I am happy to help them get some suitable solution.
You may suggest that they call me.
Several Universities are using LEAF Logging Systems,
of one form or another, usually logging the EV and
CAR CAN buses, and GPS data simultaneously.
For Logging one CAN bus only, like the CAR-CAN bus
in the iMiEV, the OBDLink SX device used with my
CAN-Do program (or RealTerm to just Log) appears
to be a good, inexpensive solution.
I do not know if the Battery Park amps and volts
are available on the LEAF's CAR-CAN bus, but that
data does seem to be available from the EV-CAN bus.
