What happens to your EV battery after 10 years and 500,000 km? According to Dr. Jeff Dahn, it's still worth a lot — and it may be quietly powering your neighbourhood's electricity grid.
World-renowned battery researcher Dr. Jeff Dahn (Dalhousie University) returns to Canada Talks Electric Cars to break down the real science behind Vehicle-to-Grid (V2G) technology and second-life battery applications — with actual data, real-world examples, and a look at what's already happening in France, North America, and your own province.
Whether you own an EV, are thinking about one, or just want to understand where energy storage is headed, this is the episode to watch.
