Ultracapacitor European market leader Skeleton Technologies is now contracted to supply SkelSart Engine Start Module units on all Brush Traction Porterbrook Bi Mode Unit Class 769 flex prime movers. For more information see the IDTechEx report on Superapacitor Materials and Technology Roadmap 2019-2039.
The high-power density, inherent safety and tiny size of the 24V SkelStart module were decisive over other solutions during feasibility stage to start the Auxiliary Power Supply (APS) units. There was simply not enough allocated space available to integrate any other solution.
SkelStart is installed as a standalone starting powerpack with no power needed to top it up during standby periods as the case for long standby does not exist with this application. A Single Skelstart is powerful enough to start 27-liter engines at 20°C.
"We had limited space available for the integration of the APS starting power supply. The 24V SkelStart has the size of a regular car battery and with its 8kg weight, it solved the space restriction we had. Also, we do not need batteries for the APS start module as the BMU standby time is short. The expected lifetime of the SkelStart of at least 5 years also adds reliability to the system." said Mr. Chris Myatt, Engineering Director at Brush Traction.
Mr Taavi Madiberk, CEO of Skeleton Technologies added "It is a major stepping-stone for Skeleton Technologies to bring ultracapacitors to the rail industry. In this case, size matters, and the power density of our cells made the difference. Millions of rail passengers will benefit from our technology"
