A power control system for a battery system includes a resistor including a first terminal and a second terminal. A normally closed transistor includes a first terminal, a second terminal and a control terminal. The first terminal of the transistor is connected to a second terminal of the resistor and the second terminal of the transistor is connected to a second terminal of the battery system. A capacitor includes a first terminal connected to the first terminal of the resistor and a second terminal connected to the second terminal of the battery system. A power inverter includes a first terminal connected to the first terminal of the resistor, a second terminal connected to the second terminal of the battery system and an output connected to a load.
