Skeleton Technologies has unveiled a 24V engine start module (SkelStart ESM) that leverages high-performance ultracapacitor technology to ensure that the engine starts at any time, in any conditions. The module fits with European vehicles and can easily be fitted in to the D02 box types commonly used by battery manufacturers, noted the company.

Dead batteries in trucks are always a nuisance. In low temperatures long-haul drivers often leave the engine idling for long periods of time just to make sure that the battery is charged. Start failures also occur when trucks are not used for periods of time or when lifting systems consume too much energy from the battery. A novel energy storage unit from Skeleton Technologies promises to eliminate the problem.

Ultracapacitors are highly efficient and able to provide much higher currents of power than lead acid batteries. They can also charge and discharge millions of times, offering lifetimes up to 500 times longer than batteries. Crucially for drivers in colder climates, the technology can operate in temperatures as low as -65°C. With the SkelStart ESM, the ultracapacitors, not the batteries, provide the power required to start the truck engine, stated the company. The batteries are then only required to provide low power loads once the engine is up and running. This effectively eradicates the problem of an engine not starting due to cold, depletion or periods of inactivity, the company added.

According to the vendor, the unit delivers fuel savings, up to 50 per cent extended battery life, faster cranking, reliable starting, well-rested drivers and reduced pollution.

Ultracapacitors are used in a range of applications including regenerative braking in hybrid buses and trucks, cold starting of diesel engines for trucks and trains, and backup power for industrial machinery.
