Digital twin for material optimisation

Henkel is launching digital twin modelling and simulation capabilities combined with real-world validation of structural materials used in e-mobility designs, writes Nick Flaherty. Henkel is combining its expertise in material application with in-house testing and validation to close the loop between digital and real-world design and testing.

Busbar connector alternative to electroplating

Penn Engineering has developed a new technique to reduce the cost of busbar connections in electric vehicles, writes Nick Flaherty. “The challenge is how to connect busbars,” says John O’Brien, global technologist at Penn Engineering. “One of the things we have seen is a move from cabling to busbars, driven by cost. Busbars are much cheaper for the same current than cables and more suited for automated assembly, which also gives lower cost.”

Metal rupture discs offer robust relief

OsecoElfab has developed a family of pressure-relief systems for lithium ion battery applications for heavy-duty, offroad e-mobility applications, writes Nick Flaherty. The low-profile, specialised, metal rupture discs support custom battery design to improve safety. They provide robust emergency relief and pressure equalisation in a single device in the event of outgassing by the battery cells.

Having a whale of a time in an offshore vessel

Corvus Energy is to supply a 25 MWh battery system for the world’s first fully-electric offshore sea vessel, writes Nick Flaherty. The vessel is an electric Commissioning Service Operation Vessel (eCSOV) that will be constructed by Armon shipyard in Spain for UK-based shipowner Bibby Marine. Corvus Energy will supply its Blue Whale Battery Energy Storage System (BESS) with 25 MWh of lithium iron phosphate (LFP) batteries.
