Embodiment Construction

[0097] The block diagram of the first embodiment of the system of the present invention is shown in figure 1 .

[0098] In this embodiment, three functional modules can be identified, namely the battery charger 1, the rechargeable power supply device 2 and the bicycle electronics device 3, which in the most general embodiment of the system of the invention are devices external to the system itself.

[0099] The bicycle electronics 3 and the rechargeable power supply 2 can actually be housed in separate housings, denoted by the same reference numerals 2 and 3 hereinafter, which can be removably connected to each other mechanically and electronically. Alternatively, the bicycle electronics 3 and the power supply 2 can be accommodated in the same housing 2a.

[0100] The battery charger 1 and the power supply device 2 can also be accommodated in separate housings, denoted by the same reference numerals 1 and 2 hereinafter, which can be removably connected to each other mechanica...

Abstract

In order to allow the charging of a battery power supply unit (4) for a bicycle electronic device (3) to be carried out even in critical temperature conditions, it is provided to supply heat energy to the power supply unit (4) when its temperature is lower than or equal to a lower temperature threshold within a closed charging temperature range characteristic of said power supply unit (4).

Description

Technical field [0001] The present invention relates to a method and a system for controlling the charging of a battery-powered unit, in particular for powering electronic devices mounted on a bicycle. Background technique [0002] Bicycle-mounted electronics, for example for controlling the electronic transmission and / or for acquiring, displaying and controlling riding parameters and various functions, require the use of a power supply unit. [0003] The power supply unit typically consists of one or more cells, often connected in series, also known as a battery pack. When batteries used for such electronic devices are of the rechargeable type, they need to be charged by an external energy source such as the power grid or a car battery through a cigarette lighter. [0004] The battery charging process should take into account certain characteristic parameters of the battery itself, which depend on its type and especially its chemical composition. This characteristic param...
