In addition, the inverter had to be customized so that it is closed and has appropriate HV-connectors.

The inverter needs some serious machining to make it usable in another car, so its not a plug-and-play thing.

I can see some work on the housing being required to operate without the charger mounted on top, but in other cars the charger could be retained. If the charger is kept, there would be no customization of the inverter, right?

You're using the Leaf inverter and motor, but are you also using the Leaf transaxle (reduction gearing and differential)?

How much did you have to modify the original chassis?

It obviously has a nicely built fully custom subframe (all the unpainted steel fabrication in the photos), which makes sense to me, but it also appears to have custom lower control arms... I'm curious about the reason for this.

I managed to get in touch with this builder (ESDI EV Technologies). I've been following them on Instagram:

The subframe is from KJB Technologies in the UK which has been modified to attach the Leaf motor.

Interesting, because one of their photos including the subframe tags allspeedengineering, which would be All Speed Engineering Ltd, which makes subframes. In fine Instagram tradition, the posts are full of irrelevant tags, including for instance "teslabattery", but in an attempt to find the photo with that tag again I found one with this comment:

First try to fit the #Nissan #Leaf drivetrain into the front frame from #allspeedengineering

I didn't find KJB Technologies in a web search, but I didn't look for long.

Anyway, clearly the easiest way to get a Leaf or other similar EV drive unit into a classic Mini is to buy the conversion subframe which fits it most closely, and modify that. There appear to be multiple subframe suppliers.

The photos here indicate 17 Leaf modules, which would be ~128V nominal.

I ran out of patience for scrolling through random photos; however, the Instagram photos show a long stack in the trunk labelled as the "battery compartment", but also frames for Leaf modules to be stacked on the interior floor in place of the rear seat. The photos in this thread show only the long (17 module) stack across the trunk. Do we know if only the trunk stack was used?
