The invention relates to an activation device with a circuit-breaker unit for a dual-battery system, which system comprises a power battery system connected to an electrical system comprising a starter motor and an ignition lock circuit for a vehicle, and a starter battery system adapted to being connected in parallel with said power battery system via said circuit-breaker unit, which circuit-breaker unit is switchable between an open state and a closed state, in which latter state said starter battery system is adapted to supplying said electrical system with energy. The activation device comprises a control unit adapted to switching said circuit-breaker unit between said open and closed states, a signal unit adapted to generating a voltage signal y1 and conveying a voltage signal y via an ignition lock connection to said ignition lock circuit, a monitoring unit adapted to monitoring a voltage signal y from said ignition lock connection and generating a monitoring signal on the basis of said voltage signal y monitored, and a processor unit adapted to comparing the monitoring signal with at least one predetermined detection criterion and generating on the basis of said comparison a control signal which is conveyed to said control unit which is adapted to switching said circuit-breaker unit on the basis of said control signal. The invention comprises also a method for activating a circuit-breaker unit in a dual-battery system. |
