better integration of BYD's proprietary blade battery technology with an improved pure electric frame structure with doubled torsional stiffness, a newly upgraded 8-in-1 module for the drive system allowing the overall efficiency to exceed 89%, a direct cooling and heating system for the battery pack (utilising residual heat from surroundings, powertrain, passenger compartment, and even the battery itself) to increase thermal efficiency by up to 20%, and shorter front overhangs, lower body profile, and a longer wheelbase to improve aerodynamics (0.21 cd) and passenger space. Power consumption per 100 kilometers is reduced by 10%, and the cruising range is 10% longer in winter. The platform enables all-electric ranges exceeding , with 800-volt fast charging technology for a range up to after 5-minutes of charging and allows an all wheel drive (AWD) system with 0-100 km/h (62 mph) acceleration of 2.9 seconds, though not all cars designed with this platform will reach this max performance. It also allows for the use of cell-to-body (CTB) battery integration. CTB replaces the previous cell-to-pack (CTP) technology which had been launched by Contemporary Amperex Technology and then dismissed by them in 2019. The first car designed using this platform was the Yuan Plus (also known as "Atto 3" in Singapore and Australia), followed by all electric cars in the new "Ocean Series" such as the Dolphin (also known as "Atto 2") and Seal (also known as "Atto 4").

The BYD Qin replaced the aging BYD F3DM, and quickly became the best-selling electric vehicle of early 2014. BYD followed the Qin with the launch of BYD Tang in 2015. This series marked the formal transition of BYD's focus into developing new energy vehicles.
