On-board device for providing engine starting power even when vehicle or vessel batteries are dead.

KBI has been providing supercapacitor-powered engine starting systems for decades to the commercial transportation market. Ten of thousands of installations nationwide.

A smaller, consumer orientated product has been developed for the Recreational & Commercial Marine Market, the Specialty Vehicle market, and the RV Market. The system is scalable, various sizes and voltages available.

These systems provide the electrical power needed to start the engine every time the engine is started, even if the vehicle’s primary battery system is dead.

The key is the power and energy density stored in the Supercapacitor. The system receives a charge from the vehicle’s electrical system and then holds that charge, isolated from the vehicle electrical system, until the next engine starting event.

Regardless of the vehicle battery state of charge the KBI system will engage and provide the needed starting power, every time the engine is started. Vehicle battery life will be extended.

Absolutely no maintenance, no electrolytes to consider, no corrosion, can be installed in any orientation, even upside down. Cycle duty life is rated upwards of one million 1,00,000 cycles. It will not wear out or degrade from being used or being stored. The system will outlast the life of the vehicle.

The KSM Kompact consists of multiple components configured together to store and deliver power to start your engine. All these components work together to ensure the flow of power and keep the power cells in optimal condition, providing engine staring power.

The capacitor module—An array of five 1200F cells power the device.

Buck boost charger—Part of the charge controller, the buck boost charger helps accurately charge the power cells, even when the primary engine starting battery power is insufficient to start the engine.

Charge timer—The charge controller has an integrated timer circuit that will activate the buck booster when the batteries are connected, and the vehicle or vessel battery switch is turned “on”. The buck boost will stay on for approximately 10-12 minutes. When the timer expires, the device will enter low power mode (Deep Sleep). The purpose of this feature is to ensure your device is always fully charged, even when your Boat or RV is taken out of storage.

Starter input—Sends the signal from the engine starter to activate the device. It only needs about 5-6 volts from the engine starter circuit to activate the capacitor contactor, perfect for low battery conditions.

Ignition signal input—When an ignition signal is received, it activates the charge controller and buck booster, which will remain active the entire time the ignition is active and the vehicle or vessel is in service. This ensures the capacitor is fully charged for the next engine starting event.

Emergency start switch—If the vehicle or vessel’s batteries are too deeply discharged to activate the capacitor module through the starter input, the ESS (Emergency Start Switch) can be used to bring the capacitor system online.

Don't get stranded with dead batteries!
