Abstract
There is provided a battery system including: a main switch configured to supply or cut off a voltage of a battery to a load; a semiconductor pre-charger module which includes a semiconductor switch configured to supply or cut off the voltage of the battery to the load, and a semiconductor switch driver configured to output a pulse signal for driving the semiconductor switch to turn on and off the semiconductor switch, and is connected in parallel with the main switch; and a controller configured to generate a control signal for controlling the main switch and the semiconductor pre-charger module, wherein the semiconductor switch driver of the semiconductor pre-charger module includes an isolation element configured to electrically isolate the controller and the voltage of the battery. Here, the semiconductor switch of the semiconductor pre-charger module may be a metal-oxide-semiconductor (MOS)-controlled thyristor (MCT).
