Currently all General Motors PHEV battery packs are built at Brownstown Battery Assembly Plant in Michigan, but that's all about to change.

Autoblog is reporting GM will shift some battery production to the Peoples Republic of China in order to qualify for green vehicle incentives. Currently GM's strategy of building them in Michigan and shipping them to China for final install is fine, but the country's 'Made in China 2025' manufacturing initiative may force a change.

Bill Wallace, GM's director of global battery systems, said battery production is "evolving," and it's safe to assume some battery production will happen in China eventually.
