- Does electric vehicle lithium batteries have risk of burning?
As a energy storage and function device fornew energy vehicles, lithium batteries have the reputation of pure electric carheart. Power battery is the core component of electric vehicle, accounting forhalf of the cost of the whole vehicle. According to the structure of electricvehicle power battery, the battery pack used in a general vehicle is composedof a plurality of small batteries connected in series, and the battery internalmaterials include a negative electrode material, an electrolyte, a diaphragmand a positive electrode, which mainly rely on lithium ions between thepositive electrode and the negative electrode. According to thecharacteristics, when the electrode material inside the battery appears,overcharge, overheat, and puncture will explode. Although it is much better interms of safety, there is still a risk of burning.
Judging from the accidents that manyelectric vehicles are currently on fire, they basically have a certainrelationship with the battery. The number of lithium batteries on electricvehicles is as small as a few hundred and as many as several thousand. Especiallyin the battery management technology of vehicles, it is not easy to manage thetechnology. For the risk of self-ignition of vehicles, even the highest-end ofnew energy vehicles in the world. Tesla is not immune to this piece. The riskof burning has a certain relationship with the working environment of thebattery. The analysis is made from the perspective of design and production ofthe battery. It is impossible for the manufacturing equipment and the testingequipment to be 100% fully qualified batteries, especially for the battery.Internal positive electrode material, negative electrode material andelectrolyte.
One of the biggest bottlenecks in thedevelopment of new energy vehicles is the power battery. The risk ofspontaneous combustion is one of the biggest reasons for new energy vehicles.Of course, how to make lithium-ion batteries no longer burn is also a researchand solution of many car manufacturers and battery manufacturers.Contact: Ashlee PengEmail:email@example.comTel:+86-13360681526Navigation
