Pay attention to the safety of lithium ion batteries, why should the Tesla battery explode? Safety of lithium-ion batteries is one of the most concerned issues of power lithium batteries. Tesla's spontaneous combustion event sounded a new energy car, especially electric cars, and Tesla battery explosion is not one or two times. When the electric car is in fire, it is not a lithium-ion battery that is really unsafe? Please see text analysis.
Pay attention to the safety of lithium ion batteries, why should the Tesla battery explode? The Tesra s model hit the lamp column in two halves in the Los Angeles high-speed driving, and then the lithium-ion battery fired to burn the vehicle body. This is the sixth accident that happened within the year of Tesla. With the social progress, the lithium-ion battery is widely used in our lives, bringing us convenience, but also brought some trouble: except for electric vehicles being tired of lithium ion batteries, mobile phones, laptops, mobile power Safety hidden dangers in lithium ion batteries occurring with SLR cameras.
Therefore, pay attention to the safety of lithium ion batteries to prevent lithium-ion batteries from becoming "bombs" around us. 1 Quick charging Tesla is Panasonic 18650 battery, this battery is not very stable now, and there is a big safety hazard. If a collision occurs, it is easy to cause explosion.
Super charging safety hazard is particularly large. Fast charging can cause lithium-ion batteries overheating, if the car itself is not good, or the heat sensor has problems, then the dangerous coefficient is extremely high. In addition, the electric vehicle wants to have high-end, then the lithium-ion battery must be high-density.
But high-density battery will also bring higher risks. 2 The battery is damaged, causing the short circuit spontaneous combustion event vehicle that may occur aggressive or reserve before stopping the ground, resulting in damage to some of the battery cells in the vehicle chassis, and there is a small short circuit in the interior, and finally Bramnires caused by thermal out of control of the battery! Although Tesla type lithium-ion battery pack is well-designed, there is a perfect protection structure and cooling system. But this can not guarantee that it is still indestructible in daily relatively complex use.
3 The overheating of the battery has led to another situation of spontaneous combustion. In a hot state, eventually trigger partial battery overheat loss (failure of battery management system), leading to vehicle knockout. In addition, there is no problem that the vehicle may have a lithium-ion battery management system! 4 The old short circuit caused by the line is the end of an old long talk, and the vehicle part of the line is aging, causing short-circuit spontaneous combustion! 6 bad driving habits to the excessive performance of the battery, well-known, 100 kilometers, speed up the proud of the group, especially the car of Tesra "crazy mode" is a very large Test, the speed of the short time is instantaneous to heat the battery, and it will also bring pressure on the stability of the battery management system.
The stability of the system will also be disordered, which will be dangerous to the vehicle. Tesla's chassis is actually a large battery pack, the chassis supply to the protection of lithium-ion batteries, once a dramatic collision, exceeding the chassis protection, these active 18650 lithium ion batteries will be ignited or even detonated. Tesla Electric Vehicle Lithium-ion battery spontaneous cause or "thermal out of control", "thermal out of control" of the so-called lithium-ion battery, in fact, the safety power-off device and protection device of the vehicle cannot control the normal state of the original battery Thermal increases, and then combustion.
The lithium-ion battery of the new energy vehicle can quickly combust, because it is itself a closed system that can react itself. In each battery, there are both reducing agents, also have an oxidant, and can be slowly charged in normal time, but it will become severely burned in the out-of control. Once the battery is managed, the consequence is catastrophic.
Summary: "Safety" is the most basic requirement of the vehicle, and Tesla has repeatedly illussed due to safety problems. For Tesla, let investors believe that their products have excellent quality, Tesla may have a lot of work to be completed.
