An energy storage technology that is proving popular in applications ranging from spacecraft to race cars may have the potential to eliminate the expensive downtime that truck drivers and fleet operators often experience as a result of dead batteries.
European manufacturer Skeleton Technologies has today announced the availability of a new 24V Engine Start Module (SkelStart ESM), which uses high-performance ultracapacitor technology to ensure engine start at any time, in any conditions. The SkelStart ESM is the only unit of its kind to be designed in a form factor that fits with European vehicles and can easily be fitted in to the D02 box types commonly used by battery manufacturers.
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. 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.
Dead batteries are a notorious problem in the trucking industry, particularly in colder climates. 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.
Priit Tamme manages a fleet on behalf a major freight forwarding and logistics company that operates across the Baltic region. After experiencing repeated problems with dead batteries in cold weather his company, Mareen, chose to trial the SkelStart ESM on its vehicles.
“Since installing the SkelStart ESM we have had no starting problems whatsoever”, he explains. “The unit is particularly useful when the engine cannot be kept idling because of local restrictions and when the batteries have been drained from using the lift gate”
“Previously we were changing the batteries every two years but we expect much longer battery life using the SkelStart ESM. We are now looking at installing the technology across our fleet”
Märt Pikkani, Head of Module Development at Skeleton Technologies explains: “With a very simple installation, truck owners and fleet operators can significantly improve the efficiency of their fleet. The SkelStart ESM delivers fuel savings, up to 50% extended battery life, faster cranking, reliable starting, well-rested drivers and reduced pollution.”
Ultracapacitors have proven to be a superior technology for heavy transportation and 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.
Skeleton Technologies is Europe’s leading manufacturer of ultracapacitors. The company’s market-leading technology has already been adopted by the European Space Agency, Tier 1 automotives and grid-scale energy storage companies.
