Summary

The likelihood that all vocations of heavy-duty truck converge on a single model for electrification remains uncertain as multiple technologies compete for market position. Considering the rapid rate of advance in low carbon combustion fuels, fuel cells, and batteries, the possibility of a fragmented market space taking hold short-term appears the likely outcome as these technologies continue to mature. Considering that combustion engines running low carbon fuels will also feature some degree of hybrid electrification, all three technologies will include battery as a critical component. This paper will explore the attributes and performance requirements for the diverse battery types: full electric, to combustion engine hybrid, to fuel cell companion. These batteries with their different energy and power needs, will require use of different chemistries to achieve optimized performance, with consideration applied to both the cathode and the anode. There are three main families of commercially available chemistries for deployment: phosphates, nickel-rich oxides, and titanates. Cummins is investigating all of these technologies, tracking their evolutions as they continue to develop, and creating products that allows us to apply optimized batteries to different powertrains in an optimized way.
