The present disclosure relates to a system and method to enable power negotiations between a Quick Charge (QC) power source with no USB power delivery (USBPD) support and a USBPD device. The proposed method identifies the support of USBPD and QC in the devices; determines the possibility of direct communication between the devices over either the D+/D−lines or the CC lines, initiates the power negotiations between USBPD device and QC power source either by translating the USBPD messages on CC line to QC signalling on the D+/D−lines and vice versa, or by handling the USBPD messages independently or combination of both; enable the fast charging of USBPD device till the maximum capacity of QC power source complying with USBPD and QC specifications.

Disclosed is a charger for charging a rechargeable battery, comprising a control device and at least one electromechanical interface device for connecting at least one rechargeable battery to the charger and supplying a voltage to said battery. The interface device comprises at least a first terminal and a second terminal and can be set to at least one first position and to a second position; the first terminal can be used for charging a first rechargeable battery when the interface is in the first position, and the second terminal can be used for charging a second rechargeable battery when the interface is in the second position.

Examples relate to a smart bag for charging a set of electronic devices. An example smart bag may comprise a set of power sources integral to the smart bag, where the set of power sources may comprise multiple power sources. The example smart bag may also comprise a power management engine that manages provision of power from each of the set of power sources to a first electronic device.

A remote controlled battery cell monitoring and control system that utilizes empirical and theoretical data to compare performance, sensor data, stored patterns, historical usage, use intensity indexes over time and tracking information to provide a sophisticated data collection system for batteries. This tracking is designed to better the specifications, designs, training, preventative maintenance, and replacement and recycling of batteries.

Embodiments of the invention include a method of charging a rechargeable battery, the method comprising the steps of: detecting the presence of a rechargeable hearing aid in a hearing aid recharger; generating a unique random ID in the charger; transmitting the unique random ID to the hearing aid using an extremely low power protocol; demodulating the unique ID in the hearing aid; using the demodulated unique ID in a low power protocol to advertise the hearing aid on a network which includes the charger; associating the hearing aid to the charger when the charger which broadcast the unique ID receives that unique ID from a hearing aid using a wireless protocol; using the wireless protocol to communicate between the associated charging station and hearing aid; radiating power from the charger to the hearing aid; and ending the association when the hearing aid is removed from the charger.
