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

Welion

WeLion is a Chinese developer of semi-solid-state lithium-ion cells

Beijing WeLion New Energy Technology was founded in 2016 as a spin-out from the Institute of Physics at the Chinese Academy of Sciences, and develops lithium-ion cells using hybrid solid-liquid electrolytes. The company supplies semi-solid-state cells for high-capacity passenger vehicle packs and produces high-power pouch cells for drones, eVTOL aircraft and other uncrewed platforms. Its SHP model codes denote high-power variants, with the trailing figure indicating rated capacity, while ESS-suffixed cells target stationary storage. WeLion operates production in Beijing and Zhejiang and is scaling toward all-solid-state chemistry. Its relevance lies in being one of the few manufacturers shipping semi-solid-state cells in commercial volumes.
