Overview

• Internal tests reportedly show a solid-state cell charging to 80% in 12 minutes and delivering more than 1,500 kilometers of CLTC range, though BYD has not confirmed these results.
• BYD plans to equip series vehicles with solid-state batteries from 2027 and start mass production by 2030.
• The new cells target energy densities of up to 400 watt-hours per kilogram, nearly doubling the output of modern lithium-ion batteries.
• The automaker denies current public-road trials of the technology in its Seal prototypes and has not disclosed official testing parameters.
• BYD is expanding its ultra-fast charging network and using AI-driven development to reach price parity with liquid-electrolyte batteries by the end of the decade.
