EV Platform Index

platforms · voltage class · next generation

15 of 17 automakers now run an 800 V or higher platform. The platform, not the trim, decides how an EV charges, ages and updates.

Voltage class across the platform index: 15 of 17 automakers have at least one 800 V or higher platform; 2 are 400 V only. A platform decides charging (voltage, curve, thermal design), battery (pack design, serviceability) and software (compute and over-the-air headroom).

Finding

The platform, not the trim, decides how an EV charges, ages and updates, and most automakers now have an 800 V platform

An EV platform is the shared mechanical, electrical and software base under a family of models: battery integration, voltage class, thermal system, compute and the reach of over-the-air updates. 15 of the 17 automakers in this index now run at least one 800 V or higher platform, which halves charging current for the same power and is why Hyundai, Kia, Porsche and XPENG models charge 10-80% in under 25 minutes.

Most automakers run several platforms at once: a first-generation EV platform, often 400 V and adapted from combustion architecture, alongside a clean-sheet, software-defined successor - Neue Klasse at BMW, MB.EA at Mercedes, SSP at Volkswagen, IMA at Hyundai. Chinese platforms moved first and furthest: BYD's Super e-Platform runs at up to 1,000 V for megawatt charging. Two EVs of similar size can therefore behave very differently on a road trip, in their fifth winter, or after their tenth software update.
