About the brand
BYD is a global leader in battery technology
In just a few years, BYD has grown from a manufacturer of innovative batteries into a major automotive group with electric vehicles for almost any type of buyer. The battery, electric motor, power electronics, and software control work in synergy and create not just another Chinese device, but a real car.
In Europe, BYD sells everything from the small Dolphin Surf to the Seal sedan and the powerful Sealion 7. At the same time, the company also sells DM-i plug-in hybrids, which should not be confused with fully electric vehicles.
The history of the BYD brand
BYD was founded in Shenzhen, China, in 1995. Initially, it produced batteries for electronics, including mobile phones and portable devices. Its experience in cell chemistry, automation, and mass production became the foundation for further development.
The BYD Auto division appeared in 2003. Unlike traditional automakers, the company came to cars from the battery industry. It gradually localized electric motors, controllers, power electronics, and semiconductors, reducing its dependence on external suppliers.
Today, the name BYD is presented as Build Your Dreams, although this is more of a later marketing interpretation. More important to the brand’s history was vertical integration: BYD develops not only passenger cars, but also buses, trucks, energy storage systems, solar solutions, and rail transport.
Why BYD started producing electric vehicles
Entering the automotive industry was a natural continuation of the battery business. BYD already had knowledge of batteries and saw an opportunity to use them in transport, but in the beginning, charging infrastructure and battery costs limited the spread of fully electric vehicles.
The Dual Mode system became a transitional technology. In 2008, BYD released the F3DM, which the company calls the first mass-produced plug-in hybrid. It could drive on electricity, but retained a petrol engine for longer routes. Later, this idea was developed into the DM-i and DM-p systems: the first focused on efficiency, the second on higher power.
At the same time, BYD was creating fully electric vehicles. The e6 model worked in taxi fleets and corporate fleets, where high mileage made it possible to test battery durability. In March 2022, the company stopped producing vehicles powered only by internal combustion engines and focused on BEVs and plug-in hybrids.
Modern trends and features of BYD electric vehicles
The brand’s main technology is the Blade Battery. It is a lithium iron phosphate battery with long, thin cells that are densely packed into the casing. LFP chemistry is inferior to some nickel-based batteries in terms of energy density, but it better tolerates frequent full charging, does not use nickel or cobalt, and has high thermal stability.
Most modern models are based on e-Platform 3.0. The integrated 8-in-1 module combines the motor, gearbox, controllers, and charging components, saving space. The heat pump helps reduce winter losses, while the Vehicle-to-Load function allows external devices to be powered from the traction battery.
The Seal and Sealion 7 use Cell-to-Body technology: the battery is part of the body’s load-bearing structure. This improves rigidity and space efficiency, but makes high-quality repair after serious damage especially important. Charging speed depends on the model: early Dolphin and Atto 3 versions are noticeably slower than the Sealion 7 and the new Atto 3 EVO.
BYD interiors usually feature a large rotating screen, voice control, Apple CarPlay, Android Auto, and generous standard equipment. Weak points remain the complex menu structure and active driver-assistance warnings, which can sometimes interfere too insistently on European roads.
Popular BYD electric vehicles
The Dolphin Surf opens the brand’s lineup. It is a four-seat city hatchback with 30 or 43.2 kWh batteries and a range of up to 322 km WLTP. The regular Dolphin is larger, has five seats, a 60.4 kWh battery, and up to 427 km WLTP, so it is better suited as a family’s only car.
The Atto 2 occupies the niche of a compact urban SUV, while the Atto 3 is a more spacious family crossover. The updated Atto 3 EVO received rear-wheel drive or all-wheel drive, faster charging, and up to 510 km WLTP depending on the version. The older Atto 3 is simpler and charges more slowly, which should be taken into account when choosing a used car.
The Seal is a low electric sedan with rear-wheel drive or all-wheel drive. The long-range version offers up to 570 km WLTP, while the all-wheel-drive version focuses on performance. The Seal U EV has a more practical SUV body, but it is not sold in all European countries.
The Sealion 7 sits higher in the lineup as a powerful coupe-like crossover with a battery integrated into the body structure. It has a heat pump, a front trunk, and an AWD version that accelerates to 100 km/h in 4.5 seconds. The larger Han and Tang remain flagships in certain markets, but their availability depends on the country.
Where BYD is heading today
The next stage in Europe is localization. BYD’s first regional passenger-car plant is being built in Szeged, and the Dolphin Surf has been announced as its first model. The timeline for the start of mass production has changed, so the direction itself is more important: European assembly, local suppliers, and the gradual adaptation of cars to regional requirements.
In Budapest, the company is creating a European headquarters and research center. Its first areas of focus are electrification and intelligent systems. This should reduce the gap between Chinese development and the expectations of European buyers regarding chassis tuning, interfaces, driver-assistance systems, and service.
At the BYD Group level, Blade Battery 2.0 and ultra-high-power Flash Charging have already been presented. In Europe, the premium DENZA Z9GT was the first to receive these solutions, not the current BYD models. Therefore, the advertised 1500 kW and nine-minute charging cannot yet be applied to the Dolphin, Atto, Seal, or Sealion 7.
BYD is suitable for buyers who want a safe LFP battery, generous equipment, and a competitive price. The compromises remain different charging speeds between models, a young service network, confusing names, and a residual value that is still not fully clear.
For the city, it is worth looking at the Dolphin Surf or Atto 2; for universal family use, the Dolphin, Atto 3, or Seal U EV are more suitable. The Seal better matches the request for a sedan and long-distance routes, while the Sealion 7 is about space, all-wheel drive, and high power.
