XPeng's 800V SiC Oil-Cooled Flat-Wire 3-in-1 E-Drive, Explained

XPeng's self-developed "800V high-voltage SiC oil-cooled flat-wire deeply-integrated 3-in-1 e-drive" was selected as an annual landmark technology.

Sounds convoluted, but it's just 800V + SiC + oil-cooled flat-wire.

800V: on national-standard fast chargers, the G6's 800V charges more than twice as fast as ordinary 400V cars.

SiC (rear motor): motor controller power modules today come in IGBT, Si, and SiC. Because of material limits, IGBT struggles above 200°C — so higher power density, higher temperature, and higher conversion efficiency all demand better power-device materials.

So stronger SiC arrived: 2.5× switching frequency, 10× blocking voltage, ~80% lower working loss, junction temperature from 175°C up to 600°C, and higher power density. Plainly: longer range and faster charging for EVs.

Thanks to 800V + SiC, the G6 adds 300 km of range in 10 minutes on S3/S4 superchargers.

Flat-wire + oil cooling: flat-wire has higher torque density; oil cooling helps heat dissipation. The G6 also comes standard with a heat pump and a more efficient thermal system.

Today the G6 580 Long-Range Plus launched at a limited-time 179,900 RMB — full-domain 800V platform plus high-level smart driving at that price is genuinely good value.
