“In 2025, EV battery deployment reached 1.2 TWh, an increase of almost 30% compared to 2024, and more than 7 times greater than in 2020.”
- Step 01
Take IEA’s figure for 2025: 1.2 TWh.
- Step 02
Convert the unit: gigawatt-hours × 1,000 = megawatt-hours, which gives 1,200,000 megawatt-hours a year.
- Step 03
Spread it evenly over a year of 31,557,600 seconds (365.25 days): about 2.28 megawatt-hours per minute.
- Step 04
Count from 00:00 UTC on 1 January of the current year, so the number resets every New Year.

- The result of those steps, recomputed four times a second in your browser. Nothing on this page is fetched live from the publisher.
- Why this can't be exact
- Real activity is not spread evenly: it clusters in working hours, weekdays and seasons, so the count runs ahead or behind the true figure at any given moment. It runs at the 2025 pace until a figure for the current year is published. Digits beyond the first two or three are the model ticking, not extra precision.
Frequently asked questions
Which published figure is the counter based on?
The International Energy Agency’s figure for 2025: 1.2 TWh.
How is the live number calculated?
Take IEA’s figure for 2025: 1.2 TWh. Convert the unit: gigawatt-hours × 1,000 = megawatt-hours, which gives 1,200,000 megawatt-hours a year. Spread it evenly over a year of 31,557,600 seconds (365.25 days): about 2.28 megawatt-hours per minute. Count from 00:00 UTC on 1 January of the current year, so the number resets every New Year.
How accurate is the counter?
Real activity is not spread evenly: it clusters in working hours, weekdays and seasons, so the count runs ahead or behind the true figure at any given moment. It runs at the 2025 pace until a figure for the current year is published. Digits beyond the first two or three are the model ticking, not extra precision.
Where does the data come from?
The International Energy Agency, “Global EV Outlook 2026” (20 May 2026). The record quotes the publisher’s own sentence, and nothing on the page is fetched live from the publisher.
