New Delhi: Shenzhen-based electric carmaker BYD has officially launched a new blade-shaped battery to mitigate concerns about battery safety in electric vehicles.
The company unveiled its new battery at an online event themed “The Blade Battery – Unsheathed to Safeguard the World”.
According to the company statement, Wang Chuanfu, BYD Chairman and President, said that the Blade Battery reflects BYD’s determination to resolve issues in battery safety while also redefining safety standards for the entire industry.
“In terms of battery safety and energy density, BYD’s Blade Battery has obvious advantages,” said Professor Ouyang Minggao, Member of the Chinese Academy of Sciences and Professor at Tsinghua University.
Due to its optimized battery pack structure, the space utilization of the battery pack is increased by over 50 percent compared to conventional lithium iron phosphate block batteries, claims BYD.
BYD further highlighted that while undergoing nail penetration tests, the Blade Battery emitted neither smoke nor fire after being penetrated, and its surface temperature only reached 30 to 60°C.
“Under the same conditions, a ternary lithium battery exceeded 500°C and violently burned, and while a conventional lithium iron phosphate block battery did not openly emit flames or smoke, its surface temperature reached dangerous temperatures of 200 to 400°C,” BYD said adding this implies that EVs equipped with the Blade Battery would be far less susceptible to catching fire – even when they are severely damaged.
Besides, BYD also stated that the Blade Battery also passed other extreme test conditions, such as being crushed, bent, being heated in a furnace to 300°C and overcharged by 260 percent. “None of these resulted in a fire or explosion,” BYD pointed out.
According to He Long, Vice President of BYD and Chairman of FinDreams Battery, many vehicle brands are in discussion with the comapny about partnerships based on the technology of the Blade Battery. He added that BYD will gladly share and work with global partners to achieve mutually beneficial outcomes for all industry players.
The Han EV, BYD’s flagship sedan model slated for launch this June, will come equipped with the Blade Battery. The new model will lead the brand’s Dynasty Family, boasting a cruising range of 605 kilometers and an acceleration of 0 to 100km/h in just 3.9 seconds, said the company.
