Chademo is go

 After quite a few trips round to the rapid charger resulting in failure, I finally had success. The code needed some tweaks, the software wasn't sending quite the right messages (the extended flag on the can messages was randomly being set and unset, explicitly setting it to false was needed).  The charger performed it's checks and then fired in to action. I'd set the max charge rate at 50 amps for this test, so a nudge under 20kw. This particular charging unit was reporting it was capable of 125 amps and 475V, the logs of this charge show the station ramped up to 50amps and I charged for 5 minutes, as I was only testing.  The hardware requirements for this are quite minimal, as the heavy lifting is done by the charging unit. I put together a basic shield for the Arduino Due (https://oshwlab.com/jamie84.jj/duechademo) and started modifying the Chademo Control Software from GitHub, my fork is (https://github.com/jamiejones85/CHAdeMOSoftware).  A couple of contactors are nee

DVLA Inspection

I decided to try get the DVLA to update the V5 to electric for the 4th or 5th time, but this time I was told I'd need an inspection before the change could be made. The inspection was by a 3rd party company.  The guy turned up and took a load of photos, looking for the changes I'd made, and tallying up the points against the points system they use to decide if it's radically altered or not. Your vehicle must have 8 or more points from the table below if you want to keep the original registration number. 5 of these points must come from having the original or new and unmodified chassis, monocoque bodyshell or frame. Part Points Chassis, monocoque bodyshell (body and chassis as one unit) or frame - original or new and unmodified (direct from manufacturer) 5 Suspension (front and back) - original 2 Axles (both) - original 2 Transmission - original 2 Steering assembly - original 2 Engine - original 1 Given that I had the original gearbox, suspension, steering assembly and only
