Electric Vehicle Industry in China

Hello everybody,
I am currently working on a research paper concerning the Chinese Electric Vehicle Industry. I have alreay (which is obvious) identified China as the leader in this technology.

I am interested in any kind of information about OEMs,Tier1 and Tier2 companies in this new industry. I have already found information on the OEMs, but it is difficult to find information about Tier1 and Tier2 companies.

Especially it would be of interest with whom they cooperate or who they suppyl with the specific components.

THANKS FOR THE HELP!!!

Take care
your Schmauss
