BYD’s battery leap: More range, less time at the plug Over 1,000 km on China’s CLTC test cycle sounds like marketing until you translate it — that’s roughly 725 km on the US EPA scale and around 900 km on WLTP. To put it another way, the old Blade Battery was doing 600 km CLTC and that was considered good. Recommended Videos The Model S Long Range, Tesla’s range king, barely clears 660 km on the EPA test. BYD just skipped past it in one go. BYD’s new “flash charging” system can go from 10% to 70% in five minutes flat, and 10% to 97% in nine. To put that in perspective, Tesla’s V4 Supercharger — currently the fastest widely deployed charging network — peaks at around 325 kW for some vehicles (though most are limited to around 250 kW) and takes roughly 15 to 20 minutes to cover the same ground. Even Porsche’s 800-volt Taycan, one of the fastest-charging EVs in the western market, needs around 18 minutes for a 10% to 80% charge. Brand
