Most people obsess over EV range—but what really matters is energy efficiency. In this post, we break down why watt-hours per kilometer tell a more honest story than battery size, and how EcoSwift’s SANY FR601 outperforms competitors by delivering more mileage with less energy. If you're serious about cutting operating costs, this is the metric that matters.

Clocking 200,000 km on an EV doesn’t automatically mean your battery’s on its last legs. In fact, mileage alone is a poor predictor of degradation. This post dives into the real culprits — calendar aging, thermal stress, and charging habits — and explains why a well-managed EV can outlast expectations. We bust the myth, share data-backed insights, and offer tips to keep your battery healthy for the long haul. Mileage tells a story. But it’s not the whole plot.
