Vehicle battery, vehicle battery pole clamp as well as a system for operating a vehicle. In the vehicle battery, an energy storage device is provided, wherein at least a first storage module 30 and a second storage module 32 each have an energy storage dev...

A method for jump starting a vehicle comprising causing a control unit to set a reference voltage by choosing a point from a chart plotting voltage across a starting battery versus time during a vehicle start; determining whether the voltage across a start...

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 batter...

The present invention is an installation of an emergency starting switching device and/or direct current boosted boost circuit device. When the power of the starting battery is insufficient, the electric energy of the auxiliary battery is used to drive the...

A main power source (2) is, for example, an ordinary Pb battery and generates a voltage of 12-13 V. At the time of starting an engine, the main power source (2) supplies power to a starter (8a). The main power source (2) is given a higher priority than an ...

The present invention aims at obtaining a power circuit for a battery which is capable of, even when an idle-stop operation is continuously performed, preventing reduction of an electric power supplied to a motor at start-up to obtain a predetermined engin...

The system has a generator (120), a battery (150), a starter (110) and a capacitor (400) of high capacitance for storing electrical energy for the engine starting process. A voltage converter (310) and an interrupter (320) are connected in parallel between...

The source for storing electrical energy is connected (D) to the normal power supply, if at the time of operating a load the temperature is below a set threshold. After use the additional source is recharged (R) ready for further use. The source may be a s...

The system has a starter battery (2), an electrical supply battery (3) and loads divided into starting-related loads and supply-related loads. A switching arrangement between the starter battery and the starting loads and between the supply battery and the...
