BYD once again carries a blow of authority in the field of electrification with the extension of the warranty for its emblematic Blade Battery, a technology that the Chinese brand has made the focus of its electric range. This battery, entirely developed by the company, Not only does it stand out for its unique structure and durability, but it has established itself as a reference in terms of security within an offer which, in Spainalready covers 12 models with 10 bodies.
More warranty, more peace of mind
The most relevant novelty is the extension of the specific warranty for the Blade Battery up to 8 years or 250,000 kilometers, with the additional guarantee that the health status will not drop below 70% within this time frame. This measure is retroactive, so any customer who already owns a BYD rechargeable model will automatically benefit from the new coverage without the need for additional steps.
This strengthening is accompanied by the continuity of remains of the brand’s official guarantees. THE anti-corrosion protection is maintained for 12 years without mileage limit, while the warranty of the traction machine (which includes the propulsion system and its controller) is set at 8 years or 150,000 kilometers. Added to this is the general vehicle warranty, which remains in 6 years or 150,000 kilometers, offering a framework of trust that goes beyond usual market standards.
The Blade Battery has achieved this position through a radically different design from conventional batteries. Her “blade” shaped structure It allows each cell to act as a structural element of the pack, increasing torsional rigidity and improving impact protection. In addition, This configuration halves the space occupied by traditional batteries, which gives greater freedom to optimize vehicle interiors.
Built with LFP (lithium ferrophosphate) chemistry, the Blade Battery does without materials such as nickel or cobalt, promoting durability and increasing thermal resistance. According to tests carried out by BYD, exceeds 3,000 charge and discharge cycles, which is equivalent to a useful life close to 1.2 million kilometers. Its performance in extreme tests (such as the nail penetration test, with temperatures below 60°C; overloads of 260%; oven tests over 300°C; crushing, salt water immersion or drops from height) revealed a margin of safety far superior to international standards.
Added to this is an advanced motor control module with silicon carbide Mosfet technology, capable of reduce energy losses by 87% And add up to 10% battery life. This efficiency is reflected in the actual figures of models such as the BYD seal design, which approves 570 kilometers in the combined cycle, i.e. the Sealion 7 Excellence all-wheel drive, whose fast charging up to 230 kW allows from 30 to 80% in just 18 minutes.
