Code name REDTOP for Real-time Electrical Digital Twin Operating Platform. Behind this name hides a research program developed by Silver Power Systems (specialist in battery data analysis), Imperial College London, the London Electric Vehicle Company (which manufactures London’s electric black taxis) as well as the JSCA, the R&D division of the Watt Electric Vehicle Company.
All these specialists have collaborated in order to develop a tool for determining the lifespan of an electric vehicle battery. To carry out their study, since January 2021 they have analyzed data from 50 electric taxis from the London Electric Vehicle Company as well as from an electric sports car from the Watt Electric Vehicle Company.
These two machines traveled 500,000 kilometers equipped with a device developed by Silver Power System to collect vehicle data. Then, this information was analyzed by EV-OPS, a platform for machine learning designed by this same entity. This artificial intelligence is able to determine the performance of the battery in real time as well as its “state of health”. Most importantly, it can predict battery life.
Technology available to all manufacturers
If this technology is still in development, Liam Mifsud, responsible for the REDTOP program, explains:
In addition to using a combination of real-world data, machine learning, and the digital twin to predict future battery degradation, we can use this technology to update an electric vehicle’s software through the cloud to change algorithms or settings to optimize battery performance as cells age and maximize battery life.
This discovery marks a turning point in the development of batteries for electric cars since any manufacturer can integrate it into its vehicles. Better still, taxi companies or private drivers can have access to data to optimize trips, range, adjust charging times or anticipate battery change.
Other sectors may also benefit from this information. We are thinking in particular of insurers who currently charge a high price for their insurance for electric vehicles, or even transport companies. “For all automotive sectors, the potential for improving battery performance and overall lifespan is revolutionary” concludes Liam Mifsud.
