BYD’s Blade Battery Meets the European Market

With BYD’s updated market launch plans for the Tang model in Norway, BYD is also bringing its new Blade Battery to Europe. BYD’s Blade Battery is a new approach to a lithium iron phosphate (LFP) battery, that aims to significantly increase safety and volumetric energy density as well as reduce costs.

The Han EV is the first mass-produced model that uses BYD’s ultra-safeBlade Battery. The BYD Han is known for improved affordability, longevity, good charging capability, and over-all safety.

BYD explains that the batteries went through rigorous testing icluding, but not limited to “a stringent nail-penetration test confirmed the Blade Battery’s surface temperature reached a remarkably low 30º – 60º C while emitting no smoke or fire” as well as a “300º C furnace test and 260% overcharging test, neither of which resulted in fire or explosive response.”

Isbrand Ho, BYD Europe Managing Director, commented on the new battery: “Our new Blade Battery is a game-changer for the EV industry, our highly skilled team of engineers have worked tirelessly to deliver even higher levels of safety – and this is a crucial factor for passenger car buyers. The Blade Battery, is the culmination of over 25-years of experience in rechargeable battery innovation, combining the latest technologies with the latest in creative thinking and production techniques.”

BYD has invested 10 billion yuan (€1.3 billion) into Blade Battery production in Chongqing, China, in hopes of achieving a yearly output of 20 GWh.

General information regarding BYD Blade Batteries is as follows:
-Lithium-iron-phosphate (LFP) chemistry
– “The Blade Battery refers to a single-cell battery with a length of 96 cm, a width of 9 cm and a height of 1.35 cm, which can be placed in an array and inserted into a battery pack like a blade”
-Cell-to-pack (CTP) system: skips the module stage through using thinner and longer cells (designed to become structural parts – beams – of the pack)
-About 50% greater volumetric energy density compared to conventional LFP battery pack
-The batteries take 60% of pack volume instead 40% in conventional system
-High longevity of 3,000 charging/discharging cycles or 1.2 million km (nearly 750,000 miles) of mileage
-High safety – BYD showed the results of a nail penetration test – of NCM, LFP and Blade Battery cells, in which the Blade Battery “emitted neither smoke nor fire after being penetrated, and its surface temperature only reached 30 to 60°C”
-Reduced cost compared to conventional LFP battery pack
-Can provide range comparable to ternary lithium batteries (NCM)
-BYD Han is rated at up to 605 km (376 miles) NEDC
-Can be charged from 10% to 80% of its full capacity within 33 minutes
