Making next-level batteries

About:Energy, an innovator in battery development software, has partnered with McMurtry Automotive to enhance technology in the latter’s record-breaking Speirling and Speirling PURE electric vehicles (EVs).

The collaboration between the British companies brings together EV expertise, battery testing and modelling to improve the battery lifetime and vehicle performance by harnessing the latest high-performance Molicel P50B battery.

This battery, with its 5.0Ah 21700 form factor lithium-ion cell, presents the best power-to-energy ratio and highest-ever energy density of 260Wh/kg.

About:Energy will accurately model the battery-cell behaviour and characterise the P50B cell’s performance.

This will enable McMurtry engineers to integrate crucial data into the design and simulations of battery packs to maximise efficient fast charging and increased cycle life performance.

Gavin White, co-founder of About:Energy, says: “We’re working with McMurtry on the quickest and most in-depth battery knowledge transfer to accelerate the development process of its vehicles.

“Our aim is to eliminate the need for costly and time-consuming in-house testing by arming companies with direct access to world-leading advanced intelligence so they can build better batteries,”

McMurtry is renowned for pushing the limits of EV performance. Its Speirling hypercar, pictured, became one of the world’s fastest pure electric cars at the Goodwood Festival of Speed Hillclimb in 2022 when it set a record time of 39.08 seconds. It had since demonstrated a world-beating 0-60mph time of just 1.40 seconds.
