Estimating the term…
A power supply circuit supplying power to components of a fixed or mobile electrical or electronic device includes a main battery, an auxiliary battery, and main and auxiliary switch units. The main battery and the main switch unit form a main power supply circuit, and the auxiliary battery and the auxiliary switch unit form an auxiliary power supply circuit. The main switch unit includes a lighting unit controlling the switching on or off of the auxiliary switch unit. When the lighting unit is switched on, the auxiliary switch unit is switched off and the auxiliary power supply circuit is disabled. When the lighting unit is switched off, the auxiliary switch unit is switched on and the auxiliary power supply circuit is enabled. An electronic device including such a power supply circuit is also provided.
