Batteries'charging levels managing method for e.g. smartphone and payment device of electronic payment terminal, involves transferring energy from one battery towards other battery based on charging levels of batteries

摘要

The method involves comparing charging level information of batteries with respective predetermined thresholds to obtain comparison results, where each comparison result is positive or negative when a charging level of the corresponding battery is greater than or less than the corresponding threshold, respectively. Energy is transferred (40) from one of batteries towards the other battery by a modular interface based on the charging levels of the batteries, where the batteries supply power to a payment device and a communication device, respectively. Independent claims are also included for the following: (1) a component for managing a charging level of two batteries supplying power to respective devices (2) a computer program comprising instructions for performing a method for managing a charging level of two batteries supplying power to respective devices.
