[Original by Dongchedi Industry] On October 23, in response to battery swap-related issues that users are more concerned about, NIO official responded in a concentrated manner, which talked about: When the battery swap station is charging the battery for full load, the radiation amount is less than one-tenth of the radiation emitted by a mobile phone.

NIO said that the shell of the battery swap station uses aluminum alloy sheets with stronger anti-penetration barrier capabilities, which can absorb and shield more than 98% of the electromagnetic radiation ; therefore, when the battery swap station charges the battery at full load, the electromagnetic radiation power transmitted by these batteries to the outside is extremely low. Specifically, the radiation at this time is less than one-tenth of the radiation emitted by a mobile phone.

In response to users' concerns about the degree of battery tightening in battery swap mode, NIO said it has created the Bayobolt fastener bolt set, which can ensure that the vehicle chassis and battery pack lock in six degrees of freedom in the three-dimensional direction. Its high durability can support more than 3,000 battery swaps in the entire vehicle, covering 600,000 kilometers of travel during the life cycle of the entire vehicle.

Among them, for the fastener bolt set Bayobolt, NIO stated that its floating fastening, anti-loosening locking, automatic thread guide and positive engagement, and high load-bearing capabilities and characteristics ensure the reliable connection between the battery and the car body, and can firmly lock the battery pack even in extreme collisions.

Regarding the safety and reliability of the battery, NIO said that after each battery enters the battery swap station, NIO will conduct dozens of tests on it to ensure health, and the test results will be synchronized to NIO Cloud, and the battery dynamics will be tracked in real time in the future.

It is worth mentioning that NIO also revealed that NIO battery swap station has more than 1,400 patents, and NIO will conduct three-electric self-check on the vehicle every time it replaces the battery. In addition, as of October 23, NIO has built 1,185 battery swap stations.
