PARIS: BYD Europe has extended the warranty of its cars' Blade batteries to eight years or 250,000km – and making the switch applicable to existing cars as well as new purchases.
Blade battery technology is at the heart of all BYD's New Energy Vehicles – pure-electric and Super Hybrid.
These cars already feature a basic-coverage warranty of six years or 150,000km, along with a 12-year, unlimited-mileage anti-perforation warranty and cover for the electric drive unit of eight years or 150,000km.
Now BYD has increased the mileage limit on the specific warranty for the Blade battery to 250,000km, while retaining the existing duration of cover at eight years and a guaranteed minimum State of Health (SOH) of 70%.
It will apply to not only new cars but also all existing BYD models.
Existing European owners with a BYD EV (electric vehicle) or Super Hybrid will automatically benefit from the expanded coverage.
The Blade battery is made using lithium iron phosphate chemistry (LFP), and has been proven to exceed 3,000 charge and discharge cycles, with a service life equivalent to 1.2 million kilometres.
It has delivered outstanding results in extreme safety evaluations, such as the nail-penetration test, during which the surface temperature remains below 60°C – 10 times lower than that of a conventional battery.
It has also demonstrated exceptional resistance in overcharge tests of up to 260% and oven tests at temperatures above 300°C, as well as in crushing tests, saltwater-immersion tests and drop tests from significant heights, far exceeding international safety standards.
The blade-shaped design allows each cell to function as a transverse structural element, increasing overall torsional rigidity and providing exceptional protection against impacts and deformation.
Each compact and lightweight cell is integrated into a module that reduces occupied volume by 50% compared with traditional batteries, enabling designers to maximise interior space and optimise vehicle packaging.
The Blade Battery delivers significant driving ranges — such as 570km in the combined cycle for the BYD Seal Design — or high charging speeds, such as those of the BYD Sealion 7 Excellence AWD, which has a maximum DC charging power of 230kW and can charge from 30% to 80% in just 18 minutes.
