Device for voltage drop stabilisation in a motor vehicle

The voltage drop stabilizing device (1) has a primary terminal (3) to connect the device with a power supply such as vehicle battery (B). A secondary terminal (5) is arranged to connect the device with a starter (S) of motor car. A starting operation detector (17) is connected with a control unit (9) to detect the starting operation. The control unit is arranged to control a current limiting module (4). The current limiting module is provided to perform the starter current limiting action based on the starting operation signal of the starting operation detector.
