Apparatus, method and article for physical security of power storage devices in vehicles
ActiveUS8560147B2Registering/indicating working of vehiclesNavigation instrumentsPhysical securityIn vehicle
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.

InactiveUS20110074346A1Safety concern can be addressedFix security issuesMultiple-port networksBatteries circuit arrangementsForeign objectSystem identification
Wireless vehicle charger safety systems and methods use a detection subsystem, a notification subsystem and a management subsystem. The detection subsystem identifies a safety condition. The notification subsystem provides an indication of the safety condition. The management subsystem addresses the safety condition. In particular, undesirable thermal conditions caused by foreign objects between a source resonator and a vehicle resonator are addressed by sensing high temperatures, providing a warning and powering down a vehicle charger, as appropriate for the environment in which the charger is deployed.
