Motorsports
McMurtry Automotive: Faster cell evaluation
McMurtry Automotive used The Voltt and validated cell models to evaluate the transition from the Molicel P45B to P50B during early pack concept development.
Side by side modelling enabled rapid comparison of electrical and thermal behaviour, avoiding lengthy physical test campaigns. This approach reduced cell evaluation time by seven months, allowing the team to lock in cell selection and pack assumptions earlier while lowering technical risk and accelerating vehicle development.

Manufacturer Background
EVE Energy
EVE Energy is a Chinese lithium-ion cell manufacturer producing cylindrical and prismatic formats
EVE Energy was founded in 2001 in Huizhou, China, and produces lithium-ion cylindrical and prismatic cells alongside a long-established primary lithium business. Its range covers lithium iron phosphate and nickel-based chemistries, with cylindrical 21700 and large-format prismatic cells serving electric vehicles, stationary storage, power tools and consumer products. The company operates plants across several Chinese provinces and has added capacity in Hungary, Malaysia and the United States to supply customers closer to their end markets. Its cylindrical range spans high-power and energy-led variants built on shared production lines. EVE is one of the broadest Chinese suppliers by application, rather than one concentrated on a single market.
