The 2025 BYD Seal hits the market, what is e-platform 3.0 Evo?

On August 8, the 2025 BYD Seal officially went on sale. The new car has launched four configuration models, and the price range is 175,800-239,800 RMB. The e Platform 3.0 Evo carried by the 2025 BYD Seal belongs to the upgraded version of e Platform 3.0, which features five major technology clusters, namely CTB overall vehicle safety architecture technology, twelve-in-one intelligent electric drive technology, intelligent wide thermal domain efficient heat pump technology, all-domain intelligent fast charging technology and intelligent motion control technology. Each of these technology clusters is further subdivided into multiple technologies.

1. The world's first CTB overall vehicle safety architecture technology cluster

Main rear drive safety power architecture: The safety buffer space in the front cabin increases by 100mm, and the frontal collision safety performance increases by 60%;

Front-mounted steering architecture: The anti-deformation ability of the passenger cabin has increased by 50%;

Internal skeleton type CTB safety architecture: The regional body strength is more than 60% higher than the industry;

New integrated vehicle safety architecture: The collision intrusion amount of the passenger compartment is less than 5mm, and the collision acceleration of the passengers can be as low as 25g.

2. The world's first twelve-in-one intelligent electric drive technology cluster

It includes a 23000rpm high-speed motor, efficient reducer, silicon carbide electric control, vehicle controller, battery manager, DC converter, on-board charger, high-voltage distribution module, intelligent boost module, intelligent lift flow module, intelligent self-heating module and energy management smart control system. It can make the highest efficiency of the electric control reach 99.86%, the system comprehensive working condition sales volume reach 92%, increase the cruising range by 50km and the extreme speed by more than 230km/h.

3. The world's first intelligent wide temperature range high-efficiency heat pump technology cluster
