Supercapacitors Improve Energy Storage in Medium, Heavy-Duty Trucks

Hybrid transportation is becoming more important as demands for reduced carbon emissions and increased vehicle efficiency increase. Manufacturers of medium and heavy-duty trucks are under pressure to implement better energy storage solutions to adhere to government standards and help consumers combat rising fuel prices. As a result, manufacturers are using ultracapacitors more frequently as an improved energy storage solution to help meet these demands.

Ultracapacitors, or supercapacitors, are often combined with batteries in a hybrid system, enabling battery-powered systems to operate more efficiently. An ultracapacitor can store a significant amount of power in a small package and when combined with a battery, it improves the power density of the hybrid supply. The battery size is also reduced, decreasing the gross weight of the vehicle and in turn, improving fuel efficiency. Ultracapacitors protect batteries from being degraded by large current spikes, which lengthens the operating life of batteries. The number of battery replacements is therefore reduced, and fleet managers can save time and money.

Ultracapacitors further improve the efficiency of trucks by cutting down on wasted energy. While trucks are stopped in traffic or at a stoplight, ultracapacitors capture energy that would otherwise be lost. Once the truck is ready to move again, the ultracapacitor quickly releases the stored energy for acceleration. Cold weather can negatively impact engine cranking when the engine relies on a battery for energy.  Since ultracapacitors provide a high energy density even at low temperatures – as low as -40 degrees Celsius – they ensure a quick cold start and eliminate failed starts.

Adopting improved energy storage solutions such as ultracapacitors is important for trucking manufacturers who strive to meet customer and government demands. By using better energy storage systems, manufacturers increase the overall efficiency of trucking applications and significantly reduce harmful emissions.

  • Ioxus uSTART® Battery Replacement for Heavy Equipment Increases Starting Reliability

    ONEONTA, N.Y., April 2, 2019 /PRNewswire/ -- Ioxus, Inc., a leading developer and manufacturer of ultracapacitors and energy storage products, announced today that the 24V uSTART® battery support system is now being offered as the heavy equipment industry's only drop-in replacement product that needs no special wiring. Using two group 31 batteries in series, with one 24V uSTART in parallel, users can replace their 4D battery in heavy equipment.

    The ultracapacitor-based product is designed with smart power electronics to assist in starting engines up to 50L for large off-road equipment.  Using the available Smartphone Bluetooth app, once the uSTART is connected to the batteries, users can look at the voltage of the batteries, the charge level of uSTART, initiate a jump start without connecting any wires, or put the unit into maintenance mode for safe removal or repairs.

    The goal of the uSTART system is to provide the vehicle with a start, no matter the condition of the existing batteries or external temperature. If the batteries run too low duread more...
