An integrated self-sustainable power supply includes a piezoelectric energy harvesting (PEH) beam, a power management unit (PMU) circuit located on the PEH beam, a rechargeable battery located on the PEH beam, and a positive regulated power supply output and a negative regulated power supply output. The PMU circuit includes electrical inputs/outputs. The rechargeable battery includes a negative access pad and a positive access pad, which are in electrical communication with the electrical inputs/outputs of the PMU circuit. The positive regulated power supply output and the negative regulated power supply output are also in electrical communication with the electrical inputs/outputs of the PMU circuit.

Integrated self-sustainable power supply

A case includes a base for receiving a portable phone and a flap hinged to the base and including a housing configured to receive a microcircuit card. A first contactless communication antenna is provided in the flap for coupling to an antenna of the microcircuit card. A second contactless communication antenna is provided in the base for coupling to an antenna of the portable phone. The first and second first contactless communication antennae are electrically connected to each other.

A method for managing the lifetime of a battery is disclosed herein. An ambient temperature is measured near a battery. The ambient temperature rises above a first threshold and, in response to detecting that the ambient temperature has risen above the first threshold, the battery is discharged. A battery system and a device operable with a battery are also disclosed.

Battery life time management

A method for managing the lifetime of a battery is disclosed herein. An ambient temperature is measured near a battery. A discharge of the battery is triggered when the ambient temperature exceeds a first temperature threshold. The battery can then be charged when the ambient temperature decreases below a second temperature threshold.
