Device for voltage stabilization in a motor vehicle

摘要

A voltage stabilization device is proposed for use in a motor vehicle. The voltage stabilization device comprises a first terminal for connecting the device with an energy source, in particular to a vehicle battery; a second terminal for connecting the device having a starting device of a motor vehicle; a current limiter module for limiting a starting current; a control unit for controlling the current limiting module, and at a starting operation detector coupled with the control unit for detecting a starting operation, wherein the current limiting module carries out a starter current limiting action on the basis of a start signal of the process startup detector.

1. A device for stabilizing the electrical system of a motor vehicle responsive to a voltage drop comprising:
a first terminal configured to couple the device with an energy source, wherein the energy source comprises a vehicle battery; a second terminal configured to couple the device to a starting device of a motor vehicle; a current limiting module configured to limit a starting current; a control unit configured to control the current limiting module; a power line directly connecting the first terminal and second terminal via the current limiting module, wherein the current limiting module comprises a primary power line portion having a primary switch and a secondary power line portion having a secondary switch coupled with a resister in serial; and a starting operation detector coupled with the power line and the control unit, wherein the primary switch turns to an open state and the secondary switch turns to a closed state limiting a starter current in response to the starting operation detector detecting a flow of the starter current to at least a portion of the power line and, in return, activating the control unit to control the current limiting module to carry out a starter current limiting action, wherein the primary switch is coupled parallel to the secondary switch.
