TRANSPORTATION

As the world rapidly moves towards greener modes of transportation, Ioxus stays at the forefront of developing that important technology. Our large cell ultracapacitors and modules provide large energy storage systems which significantly improve the efficiency of hybrid electric vehicles. By recycling the energy capture during braking, they will lower the peak power requirements on hybrid-diesel, fuel cell, or battery-based vehicles. This will dramatically change the way that diesel engines, such as the ones in mining trucks, heavy equipment, and locomotives, use energy. An Ioxus ultracapacitor stabilizes the power output of these devices, saving energy and resulting in significant life expectancy increases for fuel-cell and battery-based applications.

Ultracapacitors help satisfy the greatest diesel engine starting needs, especially starting time and reliability. Battery and capacitor combinations have been used in railway transport in Russia for over sixteen years, and now changes are being made all over the world to change these outdated “batteries only” systems. By combining an ultracapacitor with the power source, which is most often a lead acid battery, the strengths in both devices are maximized and the load on the power source will be drastically reduced. The advantages of this are shown at the very first moment that the engine is started at the maximum energy demand, shown by data of released energy versus starting time. Even under the most favorable starting conditions, the voltage drop in a fully charged battery was -40 percent at the initial starting moment. Ultracapacitors improve this and reduce that voltage drop by delivering more energy to the starter, and outperforming the battery within a short interval of 1.4 seconds.

There are two operating modes for ultracapacitors when installed in industrial equipment by application type: 1) Keeping the capacitors in the operating circuit in an uncharged state, and 2) a floating regime, which provides the highest system readiness. In the first application type, the capacitor is charged just before use. Then, after being discharged into the load, it is disconnected from the charging circuit until the next time it is needed. The advantage of this operating mode lies in the increased service life of the ultracapacitor, because its voltage stays close to zero during the time intervals between uses, which reduces “cell aging.” Locomotives commonly use the first operating mode with power from the on board battery system. The floating regime application keeps the ultracapacitors ready for immediate discharge. Special care is needed to equalize the voltages of stacked high-voltage circuits, and the service life of this operating mode would be slightly less than the first.

In conclusion, ultracapacitors, when paired with batteries, immensely improve the reliability, efficiency, and power of diesel engines. Whether it’s heaving mining equipment or a locomotive system, Ioxus ultracapacitors can make even the worst kind of starting system applications more effective. They guarantee engine starting with no dependence on the state of the on-board battery’s charge and perform well under less-than-ideal weather conditions, making the vehicle’s operation more reliable. Lastly, the application of ultracapacitors is very economically beneficial because they prolong the diesel starting system’s service life, reduce maintenance expenses and fuel waste, and increase engine shelf life.
