Everything we know about the BYD e-platform 3.0

At Auto Shanghai 2021, BYD introduced its new electric vehicle platform called ‘e-platform 3.0.’ The first fruition of the BYD e-platform 3.0 is the BYD Dolphin (pictured), which is now on sale in China and due in Australia in H1 2022. This platform would give birth to a raft of models for different passenger vehicle segments.

Open source

The BYD e-platform 3.0 integrates and standardizes components and has a newly developed body structure. BYD packages a digital and electric architecture and an improved BYD vehicle OS also in this platform. Like Geely’s SEA, BYD’s e-platform 3.0 is an open-source platform.

Dedicated EV platform

The BYD e-platform 3.0 is a dedicated EV platform, which means that designers have more freedom and can create models with extreme proportions. With the axles offset far apart, it’s possible to keep the overhangs short for a sporty design and stretch the wheelbase for a more spacious cabin. Sitting low and featuring very aerodynamic designs, EVs based on this platform can have a drag coefficient as low as 0.21 Cd. The e-platform 3.0 EVs can have a wheelbase of anywhere between 2.5 and 3.5 metres.

Ready for eAWD 

The BYD e-platform 3.0 models can employ a front ASM with up to 150 kW (201 bhp) of power and 310 Nm (229 Lb.-Ft.) of torque and a rear PMSM motor with up to 270 kW (362 bhp) of power and 360 Nm (266 Lb.-Ft.) of torque. So, it’s possible to make EVs with eAWD on this platform.

Uses the Blade Battery pack

BYD has equipped the e-platform 3.0 with an upgraded 8-in-1 module for the drive system, enabling an overall efficiency of over 89%. The company’s “ultra-safe” BYD Blade battery pack that has successfully cleared nail penetration, extreme temperature, overcharging, and many other tests and comprises LFP cells is standard in this platform. The Blade battery pack is a part of the vehicle’s structure, which doubles the body’s torsional stiffness.

Unlike most (or all other) EVs with battery packs consisting of LFP cells, EVs with Blade battery packs can have a high system voltage of 800 volts. This means that it’s possible to offer rapid charging on BYD e-platform 3.0 EVs. BYD claims that using 800-volt technology in this platform allows achieving a range of 150 km (93 miles) with just five minutes of rapid or ultra-fast charging. The high system voltage reduces power consumption by 10% per 100 km and increases the cursing range by 10% in winter.

Standard heat pump

BYD has equipped the e-platform 3.0 with a new type of heat pump as standard. The company says that this heat pump works effectively at even -30°C. It improves the range by up to 20% in the winter.

Four-digit range

BYD says its e-platform 3.0 allows a range of up to 1,000 km (621 miles). Even if it’s an NEDC range figure, it’s impressive. Customers would buy such EVs with zero range anxiety and complete peace of mind, but initially expect extended range models only in the premium models and variants.


BYD e-platform 3.0-based EVs make use of the in-house developed BYD OS. The company says that the BYD OS makes the platform expandable, upgradeable, and fully open to developers.

Ready for autonomous driving
