On page 28 of their last presentation they show pictures of their blue chip customers. They are all companies they are working with and projects they have worked on. Included in the photos is a picture of a Volvo bus which is clearly labelled (when cursor is over it) Volvo. You can draw your own conclusions from the presentation but IMO this shows they are working with three bus companies (Volvo, solaris and ebe-europa) and three forklift companies (Mitsubishi caterpillar forklift, Raymond and Mccall). Certainly placing the Volvo photo among the blue chip customers photos is indicating they are working with them. This is the photo they used in the presentation.http://www.eurotransportmagazine.com/16095/news/industry-news/gothenburg-welcomes-volvo-electric-buses/
