BYD Introduces new Blade Battery Design for BEVs
BYD, the Chinese electric vehicle manufacturer, has launched its Blade Battery, a development that it says will mitigate safety concerns.
At an online launch event, Wang Chuanfu, BYD Chairman and President, highlighted a video of the Blade Battery successfully passing a nail penetration test, and the company said that while undergoing such tests, the battery emitted neither smoke nor fire, and its surface temperature only reached 30 to 60°C. Under the same conditions, the company added ‘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. This implies that EVs equipped with the Blade Battery would be far less susceptible to catching fire – even when they are severely damaged’.
BYD also said that the Blade Battery passed other extreme test conditions, such as being crushed, bent, being heated in a furnace to 300°C and overcharged by 260 per cent, and that none of these resulted in a fire or explosion.
The singular cells are arranged together in an array and then inserted into a battery pack. Due to its battery pack structure, BYD said the space utilisation of the battery pack is increased by over 50 per cent compared to conventional lithium iron phosphate block batteries.
The Han EV, BYD’s flagship sedan model slated for launch this year, will come equipped with the Blade Battery, and the new model will lead the brand’s Dynasty Family, boast a cruising range of 605km and an acceleration of 0 to 100km/h in just 3.9 seconds.
In related news, BYD AND Toyota have announced that development of their joint venture company to conduct research and development of battery electric vehicles has reached a new milestone and operations are scheduled to commence in May 2020. The name of the new company is BYD TOYOTA EV TECHNOLOGY CO., LTD. (BTET).
This joint venture company will focus on the research and development of battery electric vehicles with technology and know-how from both China and Japan,” said Zhao Binggen, newly appointed CEO of the company. “The company is committed to promoting and populating high-quality technologies that make battery electric vehicles more environmentally friendly, safe, comfortable, and intelligent.
