In 2019, WAE entered a strategic technical partnership with Lotus, with the companies sharing research and development into advanced propulsion technologies. Central to that partnership was the Evija, featuring the world’s most power dense EV road-car battery, outputting 2000kW, and delivering world-leading fast charge times.
Following the success of delivering batteries into Formula E, WAE went on to win the battery contract for an all-new fully electric off road series, Extreme E. Designed to highlight the impact of climate change around the globe, Extreme E races races across everything from Arctic tundra (-10°C) to desert sand dunes (40°C). Despite these harsh environments, the battery system has delivered 99.9% in-race reliability whilst delivering sporting equity and ultra-high performance.

Electrified Mine Haul Trucks
Elysia’s Embedded algorithms and Cloud Platform are powering the next generation of electrified mining trucks for Fortescue. Elysia’s Embedded algorithms enable fast charging of the 1.4MWh battery system within 30 minutes, whilst ensuring minimal downtime through always-on balancing. The Elysia Cloud Platform supports remote monitoring of battery health and life forecasting, whilst safety is ensured through advanced prognostic algorithms which analyse every parallel cell group.
Elysia worked with a major OEM to assess tens-of-thousands of vehicles for potential safety concerns. The OEM had cause for concern around component quality, after experiencing a small number of thermal events in the field, wanting to understand the prevalence of the issue as well as relative risk across the fleet. The cloud platform analysed over 7 million charges and 50 million drives, identifying specific production windows of concern, where different quality issues could be attributed to prognostics flagged. This in-turn led to specific service actions being taken and further investigation to be actioned.

As exclusive battery supplier to the Le Mans-Daytona Hybrid (LMDh) set of regulations, WAE were tasked with developing an ultra-high power battery system capable of relentless operation over a 24-hour race period. Powered by Elysia Embedded, the system can operate continuously in-part due to the use of Elysia’s Always-On Balancing algorithm, ensuring the system remains reliable and in balance throughout the race event. Furthermore, Elysia’s model-based State-of-Power algorithm increases the system’s usable-energy density by more than 30%, by enabling ultra high-power operation even at extreme low and high states of charge.
