Definitely not your usual EV: China begins sea trial for world's largest electric ship — Ning Yuan Dian Kun is longer than a football field, weighs 10,000 tons, and uses 10 container batteries with a total 19MWh capacity

Ning Yuan Dian Kun.
  • Ning Yuan Dian Kun, a 10,000‑ton container ship, is powered by the equivalent of 250 Tesla‑grade batteries
  • It can swap all ten batteries at the dock like a giant phone
  • Two 875‑kW motors push this electric giant to 11.5 knots

When most people think of electric vehicles, they imagine a sedan or an SUV, not a vessel that underwent sea trials off Shanghai in February 2026.
