EMW is working on a range of products to improve electric vehicles, primarily focusing on charging. They've developed some very high power chargers (12 kilowatt, 25 kilowatt) that are very inexpensive. The chargers are pseudo-open-source, and controlled via Arduino boards, set up in a way so anyone can customize the firmware for their own purpose.

The video below demonstrates one of those chargers coupled with a CHAdeMO controller box coupled with a CHAdeMO plug. All this was designed in the open by several people.

The end goal is being able to grab a CHAdeMO fast charge at, say, an RV park where there's NEMA 14-50 (240 volts 50 amps) service.
