Tesla Motors has opted not to pursue the development of battery packs for Think Global, according to Darryl Siry, Tesla Vice President of Sales, Marketing and Service.
In May, Tesla Energy Group, a newly-formed division of Tesla Motors, announced an agreement to supply Think Global with lithium-ion battery packs (derived from Tesla’s battery pack design for the Tesla Roadster) for the Th!nk City cars. That supply agreement covered the development and delivery of battery packs starting in December 2007 and continuing through 2008.
After Michael Marks became CEO of Tesla Motors, one of the first actions he took was to inform Think that we would not pursue the development of battery packs for them at that time because we had to be focused entirely on our own vehicle programs. We hope to work with Think in the future, but for now it is important that we stay focused on our own vehicle programs.—Darryl Siry
In October, Think Global announced it had selected EnerDel as the supplier of choice for prismatic large format Li-ion batteries that will be used to power its Th!nk City electric vehicles. (Earlier post.)
To counter a growing perception that problems with the Tesla battery pack were behind the delays in delivering the electric Roadster—and Think’s shift to EnerDel—Siry wrote that:
The primary cause of our delay has been and continues to be issues with durability and reliability of the transmission, as we have reported before.
