New software that could enable OEMs to reduce battery size without reducing performance or range has gone on display at the IAA Mobility 2023 motor show in Munich.

Elysia battery intelligence software enables a reduction in battery size of up to 19%, for the same performance and range

Developed by WAE Technologies, the Elysia software is said to have proven a reduction in battery mass of up to 19%, without impacting range.

The suite of battery intelligence technologies draws on WAE’s background in providing high-performance batteries to a top-tier electric motorsport series, as well as the design and development of batteries for road cars, electric hypercars and 250-tonne mining trucks.

Its suite of algorithms hasa been designed to unlock extra performance from an electric vehicle battery, bringing a host of benefits for car makers that can also be passed on to consumers.

Commercial lead Joe Jones explained: “Every OEM wants to reduce cost and improve performance across a range of metrics. We are now seeing questions being asked of the EV industry from consumers becoming more aware of the impact of the weight of heavier electric vehicles and the resources required to produce batteries.

“By using software alone to enable a reduction in the number of cells required, an OEM can deliver consumers the same performance with less cost, lower environmental impact and reduced weight.”

The software solution has been developed to unlock a battery’s ability to accept more of the energy recovered by regenerative braking, extending the useable state of charge windows, thanks to accurate, health-adaptive state estimation algorithms.

Jones finished up: “We can see that efficiency of energy use is becoming something that is becoming more important in the EV market and Elysia Battery Intelligence can help OEMs get more from less.”
