Abstract

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To avoid theft and tampering of the portable electrical energy storage devices, by default, each portable electrical energy storage device is locked in and operably connected to the vehicle to which it provides power unless the vehicle comes within the vicinity of a collection, charging and distribution machine or other authorized external device such as that in a service center. Once within the vicinity of a collection, charging and distribution machine or other authorized external device a locking mechanism in the vehicle or within the portable electrical energy storage device unlocks and allows the portable electrical energy storage device to be exchanged or serviced.
