VARTA Microbattery : Energy Supply of Smart Car Keys
Car keys get increasingly in the focus for automotive OEMs. Size, safety and extended user functions are targets for future key fobs. In the meantime inspiring functions in smart car keys are state of the art. The challenge in the next generation of smart key-fobs is to save space and provide more functionality. For this purpose a conventional primary cell does not provide enough capacity anymore. Respective space and capacity requirements do also not allow using a Lithium pouch type battery which is ineffective in volumetric energy density.
