摘要:
The invention relates to a device for digitally displaying the electric charge stored in electriticy storage devices. According to the invention, a charge meter (1), a monitor (8) and a monitor controller (6), formed using flexible printed electronics, are incorporated into a flexible plastic support (9), in which the tracks of the corresponding electronic circuits have been printed with conductive ink, said circuits being soldered to the tracks. The resulting device is fitted externally to the wall of the battery, at any visible point thereof, and the output cables of the electronic module measuring the charge level are connected to the battery terminals. The entire assembly is secured and protected by means of external plastic coating.
