In order to improve the performance of a battery power supply unit (4) for a bicycle electronic device (3) at low atmospheric temperature, when its temperature is less than or equal to a lower temperature threshold, electrical energy is supplied by the power supply unit (4) to a heating element (5) thermally coupled with the power supply unit (4) that, in this way, self-heats. Part of the electrical energy of the power supply unit (4) can be simultaneously supplied to the electronic device (3). |
