Described herein are improved capabilities for a source resonator having a Q-factor Q 1 >100 and a characteristic size x 1 coupled to an energy source, and a second resonator having a Q-factor Q 2 >100 and a characteristic size x 2 coupled to an energy drain located a distance D from the source resonator, where the source resonator and the second resonator are coupled to exchange energy wirelessly among the source resonator and the second resonator.

Wireless energy transfer systems

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To charge, the machines employ electrical current from an external source, such as the electrical grid or an electrical service of an installation location. By default, each portable electrical energy storage device is disabled from accepting a charge unless it receives authentication information from an authorized collection, charging and distribution machine, other authorized charging device, or other authorized device that transmits the authentication credentials. Also, by default, each portable electrical energy storage device is disabled from releasing energy unless it receives authentication information from an external device to which it will provide power, such as a vehicle or other authorization device.

Apparatus, method and article for authentication, security and control of power storage devices, such as batteries

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.

Power supply system and method of controlling power supply system

A maximum value selecting part (50) receives battery voltage values (Vb1,Vb2) to output the maximum one of the received battery voltage values to a lower-limit-value limiting part (54). A maximum value selecting part (52) receives voltage request values (Vm1*,Vm2*) to output the maximum one of the received voltage request values to the lower-limit-value limiting part (54). Limiting a voltage target value (Vh*) such that it is not below the output value of the maximum value selecting part (50), the lower-limit-value limiting part (54) outputs the limited voltage target value. Switching commands (PWC1,PWC2) are generated based on a control calculation using a combination of a voltage feedback control element and a voltage feedforward element and based on a control calculation using a combination of a current feedback control element and a voltage feedforward element, respectively.

A converter ECU obtains allowable power total value including at least one of discharge allowable power total value .SIGMA.Wout of discharge allowable power Wout1, Wout2 and charge allowable power total value .SIGMA.Win of charge allowable power Win1, Win2. Then, the converter ECU determines which of the allowable power total value and an actual power value is greater. If the actual power value is smaller than the allowable power total value, the converter ECU controls a converter such that an input/output voltage value Vh attains a prescribed target voltage value, and at the same time controls a converter such that a battery current value Ib2 attains a prescribed target current value.
