Embodiment Construction

[0063] figure 1 An equivalent circuit diagram of an inrush current limiting system 2 with an inrush current limiting device 2 a and a disconnecting device 2 b is shown. It is also shown that the starting current limiting device 2 a has a first contact 4 and a second contact 6 . The first contact 4 corresponds to the battery 8 . The second contact point 6 corresponds to the electric starter motor 10 .

[0064] therefore figure 1 The electric starter circuit is shown. During starting, the starter current flows from the vehicle battery 8 , in particular from the positive pole of the battery 8 , to the starter 10 via the starting current limiting system 2 .

[0065] The starter 10 requires a high electrical power during starting, ie both during a warm start and during a cold start. This results in a very high current from the battery 8 to the starter 10 in the circuit shown. Particularly in the case of a hot start, when the auxiliary consumers have been switched on, a sudden...

Abstract

For the electrical protection of a current control device 12 against overcurrents, a starting current limitation system is proposed with a first electrical connection 4 connectable to a motor vehicle battery pole 9, a second electrical connection 6 connectable to a starter 10, and a parallel circuit connected between the first connection 4 and the second connection 6, comprising a branch with a current control device 12 and a branch with an electrical resistor 14, in such a way that, at the beginning of a warm start of the motor vehicle, a starter current is conducted via the resistor 14 and that, after the beginning of the warm start, the starter current is conducted via the current control device 12 and the resistor 14.

Description

technical field [0001] The present invention relates to a starting current limiting system, an operating method of the starting current limiting system and an application of the starting current limiting system. Background technique [0002] In discussions about the savings potential of automobiles in terms of fuel consumption, automatic start / stop control technology is often mentioned. In this technology, the car's internal combustion engine is automatically switched off during prolonged idling. If the user wishes to continue driving, he only needs to depress the accelerator pedal and the engine will restart automatically. [0003] During this so-called hot start, the electric starter of the internal combustion engine, simply called a starter or starter motor, must be driven with very high power. If only a single battery, for example a lead-acid battery or a lithium-ion battery, is installed in the vehicle, voltage disturbances occur at the battery poles due to the high p...
