Beschreibung
Zusammenfassung:	Embodiments herein relate to an arrangement 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). 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 first switch (S1). A third source of electrical energy (V3) is provided, such that it is selectively connectible in parallel with the alternator (A) via a second switch (S2).
