In recent years, new energy vehicles, especially pure electric vehicles, have been developed very rapidly, and many consumers have changed their attitude towards its attitude, and market sales are also climbing. However, there is no problem with electric vehicles. On the one hand, the mileage anxiety of electric vehicles has always been difficult to solve, and the instability of the electric vehicle battery pack also adds some spontaneous risk of spontaneous combustion. Just in January this year, South Korea has once again happened a pure tram for no reason, and knocked the alarm for people.

At the end of January this year, a self-ignition accident occurred in the streets of Kona, and the firefighters were burst, and the accident did not cause greater losses. However, it is worth mentioning that this car was taken in 2020 because of the recall of the battery, and then a self-ignition occurred again, and it could not help people doubt it. It is to know that the brand’s model has taken at least 15 self-ignitions since 2018, bringing great hidden dangers to consumers.

Under this pressure, the Korean Modern Group has not announced the recall of 32,854 KONA electric vehicles in the country and 236 electric buses and more than 21,000 or more Ioniq, which is completely replaced by the LG chemical battery equipped. Such a large-scale multi-batch replacement power battery is still the first time. From a cost-input, such a large number of models need to be replaced, and the total cost is more than 1.8 billion US dollars, which is a very large input for any company.

At this incident, many people suspect whether the chemical power battery of LG is reliable. In fact, the power battery produced by LG Chemicals accounted for 23.5% in the power battery market in 2020, ranking the second place in all brands, can say that there is a pivotal position. So can the car manufacturer have replaced the battery, can it ensure that the vehicle is absolutely safe?

If you want to answer this question, you have to start with the battery itself. Among the composition of many chemical batteries, the three-dimensional lithium battery is adopted by many manufacturers with high strength and energy density. However, the disadvantage of the three-dimensional lithium battery’s own thermal stability has never been solved, which has become a large vocabulary of many electric vehicles. However, in order to strive for more market share, manufacturers usually use a large number of freight kilometers as a major indicator of vehicle assessment, so that the three-yuan lithium battery will occupy a great market guarantee.

On the other hand, the blade battery launched by domestic manufacturers has experienced strict “acupuncture experiment”, with strong safety, and manufacturers also increase the energy density of lithium iron phosphate batteries to the level of three-yuan lithium battery, and endurance. It has also been well guaranteed. Therefore, BYDo, which is equipped with a blade battery, can have such excellent sales. It turns out that whether it is a fuel or electric vehicle, safety is the greatest reliability of a car.
