Zusammenfassung:	Embodiments herein relate to an arrangement (1) and a method for improving the performance of an electrical system of a vehicle having an internal combustion engine provided with a start/stop system. The electrical system further comprises a primary battery (V1) which is selectively connectible to a starter motor (S) for the internal combustion engine via a starter solenoid (SS). A secondary battery (V2), an alternator (A) and additional vehicle electrical loads (Z) arranged in parallel with each other and selectively connectible in parallel with the primary battery (V1) via a charge switch (S1). In parallel with the secondary battery is further arranged a DC/DC converter (DC/DC) in series with a third source of electrical energy (V3).
