Toby Hagon, an automotive journalist who has driven everything from McLarens to "boring golf cart type" EVs, breaks down the practical realities of electric car ownership. The conversation centers on one crucial distinction that even energy ministers get wrong: kilowatts versus kilowatt hours. "Kilowatt hours is like litres in your fuel tank," Hagon explains. Most EV batteries hold between 50 and 100 kilowatt hours — roughly the same range as petrol and diesel cars hold litres of fuel. Kilowatts, by contrast, are the speed at which you use or shove in that energy, like speed versus distance.
The Charging Landscape: Home, Speed, and Confusion
Charging at home comes in several speeds. A standard power point delivers 2.3 kilowatts — the slowest option, giving roughly 10 kilometres of range per hour of charging. A proper home charger typically delivers 7.4 kilowatts, which will fully charge most EVs overnight in about 10 to 11 hours. For most people, Hagon says, "just put in a single phase 7.4 kilowatt charger. That'll cover off everything."

Show Notes
Motor journalist Toby Hagon joins Shirtloads of Science to talk all things electric vehicles. We break down the often-confused difference between kilowatts and kilowatt-hours, compare EVs against petrol cars on performance, energy use, and cost, and explore everything from single to quad-motor setups.
Toby unpacks AC vs DC charging and battery basics, looks at how servicing costs stack up, and separates real EV fire statistics from the hype. This was a big one, so we split it in two - catch part two next week
