How do I prolong my EV battery's lifetime? - Prof. David Howey

Our guest for today's show is Prof. Stefano Passerini. As battery researcher he works for the Austrian Institute of Technology (AIT) in Vienna, he is the former director of the Helmholtz Institute Ulm (HIU) and Senior Distinguished Fellow of the Karlsruhe Institute of Technology (KIT).

Before purchasing a second-hand battery-electric vehicle, every buyer and seller asks themselves how the battery state of health (SoH) can be determined as precisely as possible.

Our guest for today's episode is John S. Kem, President of American Battery Factory. ABF is currently building up a 4-GWh LFP gigafactory in Tucson, Arizona. A business approach, you wouldn't necessarily see in Europe.

How battery modeling saves unnecessary investments and time! Today, we are talking to Gavin White (CEO About:Energy), a #battery software company from London. About:Energy operates an interesting business model!

As electric vehicles are getting more popular, battery technology has become a focus of interest. EV owners regularly ask themselves how to treat a vehicle’s battery: How should an EV be charged, parked or driven if the inside batteries should be kept in best possible shape?

Battery manufacturers around the world have been announcing solid-state cells for its groundbreaking characteristics. Yes, we see multiple outstanding (almost-) solid-state lab cells (some of which are already on the market!) but the high expectations have never really met reality: Not a single car manufacturer is currently placing all-solid-state cells in their EVs. So, whats taking them so long?

This podcast episode deals with an energy storage technology that is still underestimated in materials science: Hybrid battery supercaps. Supercaps are installed, for example, for regenerative braking (recuperation) in vehicles such as buses, trains, cranes and trains. The powerful energy storage systems are also found in wind turbines. Now, the Estonian company Skeleton Technologies invented a new hybrid form of battery supercaps.

EV sales in India surpassed 150,000 units for the first time in May 2023. An outstanding annual growth of 64% compared to last year 2022. Market observers as well report a sharp rise in electric two-wheeler sales due to national subsidies and an expanding charging infrastructure.

Self-healing materials have the ability to automatically repair damages to themselves without any external diagnosis or intervention. Soon, they could be used in battery electrodes as well! This would impact the entire battery world - since everlasting cells definitely change the business for nearly every manufacturer.

Before purchasing an electric vehicle, all eyes are on the battery: Among first questions concerning range anxiety and charging speed, most people ask how much loss of capacity the battery will suffer over its average useful life. In this podcast, we talk about (the very normal) degradation of batteries, state of health (SOH) measurements and the research of predicting a battery's lifetime.
