An assembly of batteries includes a first battery and a second battery electrically connected in parallel. The first battery is configured to deliver a battery capacity in a first power supply voltage range. The second battery is configured to deliver a battery capacity in a second voltage range. An upper limit of the second voltage range is set between upper and lower limits of the first voltage range. In an operating system, if supplied battery power falls below a threshold, the parallel connected first and second batteries are disconnected from the load.

Protection of a battery against an extended chargeless period

An object containing electronic circuits and a rechargeable cell, wherein the cell is arranged close to a surface of the object, a charge coil being shiftable with respect to the cell between an operating position where it is arranged around the cell and a recharge position where it is axially offset with respect to the cell.

Rechargeable in-the-ear hearing aid

A method for protecting a thin-layer battery, including the steps of: periodically operating the battery at a forced discharge current, which is a function of temperature; and disconnecting the battery as soon as the voltage across it reaches a threshold, said threshold being greater than its critical voltage for a maximum discharge current under a maximum temperature.

Circuit for protecting a thin-layer battery

A method for protecting a thin-layer battery connected to an intermittent load including the steps of periodically operating the battery at its maximum discharge current, and disconnecting the battery as soon as the voltage across it reaches a threshold value greater than its critical voltage for the maximum discharge current.
