On March 29, BYD announced the official launch of a 'blade battery' with super strength and safety. The battery needle test showed that the 'blade battery' had no open flame and smoke after penetration, and the battery surface temperature was only 30-60 At about ℃, the egg on the surface of the battery has no change and is still in a flowable liquid state. Wang Chuanfu, Chairman and President of BYD Group, said bluntly, “The blade battery embodies BYD’s determination to completely end the safety pain points of new energy vehicles, and it is more capable of completely erasing the word''spontaneous combustion'' from the dictionary of new energy vehicles.' The battery has been installed in BYD Han and BYD Tang EV models.

A few days ago, Funeng Technology announced the mass production of 'XX Fire' batteries in conjunction with GAC New Energy. GAC Aion V model is a project of XX equipped with a new thermal runaway technology power battery. The thermal runaway technology has undergone strict third-party thermal runaway experimental testing. After the battery was heated for 394 seconds, the first battery cell was triggered to run out of control. In the following 24 hours, the battery pack did not catch fire and gradually returned to a safe normal temperature state. After the battery pack was out of control, 'XX caught fire'. It is understood that the power battery equipped with this model has been mass-produced and installed at Funeng Technology’s Zhenjiang plant with Industry 4.0 standards in June this year and delivered to end users successively.
