BYD transfers its advances in charging, safety and artificial intelligence from the laboratory to production vehicles

Innovation in the automotive sector acquires its true value when it moves from laboratories and motor shows to the roads. With this premise, BYD is transferring various technologies developed in-house to its series-production vehicles to improve safety, facilitate driving and reduce the environmental impact of mobility.

The company’s global research and development strategy is supported by a workforce of more than 120,000 engineers, distributed across more than 30 industrial parks and 11 research centres. BYD says it has invested more than 250 billion yuan — 32.397 billion euros — in R&D throughout its history. In the first quarter of 2026 alone, investment reached 11.3 billion yuan, equivalent to 1.464 billion euros.

The result of this effort is reflected in technologies applied to areas such as ultra-fast charging, body control, structural safety, manoeuvrability and driving assistance systems.

FLASH Charging: ultra-fast charging to reduce waiting times

One of the main challenges of electric mobility is reducing the time needed to restore range. BYD’s FLASH Charging technology aims to bring the charging experience closer to refuelling, with power outputs of up to 1,500 kW through a single connector.

This solution is used in DENZA models, BYD’s premium high-technology brand, and enables the commitment known as «Ready in 5, full in 9 and cold +3» to be met. Under this approach, the vehicle can go from 10% to 70% charge in five minutes and from 10% to 97% in nine minutes. During the press presentation of the DENZA Z9GT in Spain, the brand said that the latter figure was exceeded with a time of eight minutes and 51 seconds.

The system is also designed to operate in extremely cold conditions. Specifically, it can go from 20% to 97% in 12 minutes at temperatures as low as 30 degrees below zero.

The charging stations feature a T-shaped connector and suspended cables. This configuration is intended to make handling easier for users from either side of the vehicle, while also keeping the cables off the ground.

To support the rollout of this technology, BYD has announced the installation of 3,000 FLASH Charging stations in Europe before the end of 2027. Of these, 300 will be located in Spain and 50 in Portugal.

DiSus and e3 Platform: greater control over vehicle dynamics

The company has also developed the DiSus family of systems, a series of intelligent technologies designed to control body movements. In their most advanced configurations, DiSus-X and DiSus-Z enable vehicles from YANGWANG, BYD’s luxury brand, to react actively to acceleration, braking and uneven road surfaces.

The YANGWANG U9 equipped with DiSus-X has publicly demonstrated capabilities such as dancing, jumping and moving with just three wheels. These demonstrations serve to illustrate the scope of BYD’s body-control system.

In high-performance vehicles, the e3 Platform combines three electric motors, two of them integrated into the rear propulsion unit. The platform uses a 15-in-1 architecture, and one of its motors can reach a maximum speed of 30,000 revolutions per minute.

In the DENZA Z supercar, this technology is combined with DiSus-M magnetic adaptive damping, which controls damping rapidly and precisely during both extension and compression.

The e3 Platform also integrates the Vehicle Motion Control system, with a data transmission speed of 10 milliseconds. Thanks to this architecture, models such as the DENZA Z9GT and the DENZA Z can perform a compass-style turn, pivoting on the front axle while the rear wheels rotate around it. The turning radius is 4.62 metres.

The system also enables diagonal movements at angles of up to 15 degrees, a function intended to facilitate certain parking manoeuvres. It also incorporates the Tyre Burst Control System, which detects a tyre blowout and adjusts the torque of the wheels that remain operational within milliseconds to maintain stability and correct the vehicle’s trajectory.

Cell to Body: the battery as part of the structure

Passive safety occupies another prominent position in BYD’s technology strategy. The Cell to Body (CTB) architecture directly integrates the Blade Battery cells into the vehicle’s frame structure.

In the DENZA Z, this solution raises torsional rigidity above 40,000 Nm/degree and enables it to absorb up to 30% of the energy generated in a side impact. The company also says that some of its integrated architectures have withstood impact tests involving two-tonne palm trees without the passenger compartment undergoing deformation.

The strength of the structure is complemented by the chemical safety characteristics of the second-generation Blade Battery. This battery has passed an assessment combining FLASH Charging ultra-fast charging with a nail penetration test after 500 continuous charging cycles. The test recorded no thermal runaway, smoke or combustion.

The Blade Battery 2.0 also passed a simultaneous short-circuit test involving four cells at temperatures above 700 degrees Celsius without fire or deflagration, according to information provided by BYD.

Artificial intelligence for assisted driving

Artificial intelligence is also applied to driving assistance systems. BYD’s intelligent driving strategy is embodied in the update to the God Eye system, already available across the company’s range in China.

This system uses LiDAR sensors, high-definition cameras and millimetre-wave radars to build a three-dimensional map of the surroundings with different levels of redundancy. Its operation is supported by the XUANJI A3 chip, described by BYD as the first 4-nanometre driving-processing unit developed in China.

The chip is prepared to support Levels 3 and 4 of autonomous driving and offers computing power of more than 2,100 TOPS per vehicle. The artificial intelligence ecosystem also draws on real-time information from more than 2.65 million vehicles, which travel over 160 million kilometres every day.

Inside the passenger compartment, the system is combined with DiLink AI Intelligent Cockpit, a digital assistant with advanced reasoning capabilities that can proactively perform tasks to simplify certain actions for the driver.

Zhengzhou: a test track for validating the technologies

BYD’s test-track complex in Zhengzhou, China, serves as a development, validation and demonstration site for these solutions. The facility has eight functional areas for reproducing different driving conditions and types of terrain.

These include a speed circuit for testing longitudinal and lateral acceleration, a low-friction ring simulating ice and snow surfaces, and a dynamic paddock for slalom, evasive manoeuvring and automated parking exercises. It also has a Kick-Plate platform, designed to recreate losses of grip and assess assistance systems.

The complex also has an indoor dune, a vehicle pool with underwater windows, off-road tracks and a camping and rest area. The dune reaches 40 metres in height and has an inclination of 28 degrees. More than 6,000 tonnes of sand and 68 material tests were needed to build it, until a stable and safe mixture was achieved.

The facility also includes a dedicated intelligent-driving area for assessing advanced driver-assistance systems and autonomous-driving technologies.

With this approach, BYD argues that the advances developed in its research centres must translate into specific functions for users: faster charging, greater vehicle control, structural protection, easier manoeuvres and intelligent assistance. The company was founded in February 1995, has been present in Europe since 1998 and holds more than 65,000 proprietary patents related to batteries, electric motors, electronic control systems and semiconductors.
