BYD has strengthened its commitment to Irish motorists by extending the warranty on its Blade battery to 250,000 kilometres or eight years, whichever comes first. The enhanced cover applies to both existing vehicles and new purchases. While the mileage limit has increased, the duration of the warranty remains at eight years, with a guaranteed minimum State of Health of 70 percent. BYD says the move is designed to further enhance customer confidence in its electric and plug in hybrid technology.
Blade battery technology underpins all of BYD’s New Energy Vehicles, powering both fully electric and Super Hybrid models. In addition to the battery warranty, BYD vehicles are covered by a six year or 150,000 kilometre general vehicle warranty. There is also a 12 year unlimited mileage anti corrosion warranty and separate cover for the electric drive unit for eight years or 150,000 kilometres.
The Blade battery uses lithium iron phosphate chemistry, a formulation known for its safety, durability and sustainability. This chemistry eliminates the need for nickel and cobalt, reducing reliance on scarce raw materials and lowering environmental impact. Its distinctive blade shaped design is another key feature. Each battery cell is integrated as a structural element within the pack, increasing torsional rigidity while also providing enhanced protection against impact and deformation.
In extensive load and endurance testing, the Blade battery has demonstrated more than 3,000 charge and discharge cycles, with a potential service life equivalent to approximately 1.2 million kilometres under laboratory conditions. These innovations contribute to strong real world performance. For example, the BYD SEAL Design offers a driving range of up to 570 kilometres, while the BYD SEALION 7 Excellence AWD supports DC charging speeds of up to 230 kW, enabling a charge from 30 percent to 80 percent in approximately 18 minutes.
With the extended warranty now in place, BYD is positioning its Blade battery technology as a benchmark for safety, longevity and performance in the Irish electric vehicle market.
