Abstract
A system for controlling supply of a device. The device can be a power retention device that requires to be permanently powered. To this end, it can be alternatively powered by a power supply, in a first mode, or by a battery, in a second mode. At least one sensor of the system acquires data related to the battery, such as environmental data, the voltage of the battery or the discharge current of the battery. Based on the data and at least one characteristic curve of the battery, a battery monitoring module is configured to switch between the first and second modes to improve the lifetime of the battery.
