BYD Sealion 7 Fast Charging Review: Real-World Test at 120 kW DC Charger

Share

BYD Sealion 7

The electric vehicle journey is no longer about promises—it’s about real-world performance.

Among the latest models making waves, the BYD Sealion 7 stands out not just for its design and power but for something every EV owner truly cares about: charging experience.

We often see bold claims of fast charging in spec sheets, but the real test lies at the charging station.

Recently, I had an interesting charging experience with the BYD Sealion 7.

We often hear claims about EVs taking fast charging seriously, but when you actually see the numbers in action, that’s when the story gets real.

I plugged the Sealion 7 into a 120 kW DC fast charger, and the car consistently drew almost the full capacity all the way up to 80% state of charge (SOC). No dramatic tapering.

No sudden drops. Just a steady, strong pull—clear proof of how far EV battery technology has progressed.

For anyone following EV adoption closely, you know this is a big deal. Many cars promise fast charging, but only a few truly hold charge power this well till 80%. That’s the sweet spot for quick top-ups during highway runs.

Moments like this remind me how the EV ecosystem is maturing—where battery packs, BMS, and chargers are finally speaking the same language.

The Sealion 7 didn’t just charge fast—it showed that fast charging can also be stable and reliable.

Because the future of mass EV adoption isn’t just about bigger batteries; it’s about building confidence in the charging experience. And for me, the Sealion 7 offered a glimpse of that future.
