1. A method for controlling a super capacitor module for a vehicle with a high voltage battery, wherein the super capacitor module is connected to the high voltage battery and_comprises:
a low voltage super capacitor, a high power control electronics for controlling and actuating charging of the low voltage super capacitor, a high-powered DC-DC converter connected to the low voltage super capacitor and connected to a low voltage power supply system, a voltage comparison circuit connected to the low voltage super capacitor and connected to a low voltage lead-acid battery, the super capacitor module being connected to at least one Electric Control Units (ECU) for a vehicle or a starter motor for a vehicle, wherein the method comprises the steps of:
detecting whether a low voltage lead-acid battery is attached to the super capacitor module, in response to detecting that a low voltage lead-acid battery is attached to the super capacitor module, operating the high-power control electronics for charging the low voltage super capacitor so that the voltage of the low voltage super capacitor is above a nominal voltage of the low voltage lead-acid battery,
detecting whether_a low voltage lead-acid battery is not attached to the super capacitor module, and checking whether at least one ECU is connected to the super capacitor module, in response to not detecting that a low voltage lead-acid battery is attached to the super capacitor module and detecting that an ECU is connected to the super capacitor module, operating the high-power control electronics for charging the low voltage super capacitor within allowable intervals for the at least one ECU,
detecting whether the starter motor is not attached to the super capacitor module, in response to not detecting that the starter motor is attached to the super capacitor module, utilizing the high-powered DC-DC circuit to convert high voltage power from the high voltage battery to low voltage and supplying the low voltage to the low voltage power supply system.
