OBC invented the NiMH rechargeable battery technology that is used globally in most hybrid-electric vehicles, and in many consumer and commercial rechargeable batteries. However, Lithium Ion technology is now preferred by virtually all automakers in new development programs. It is also heavily subsidized by taxpayers through various government grants.
