It can be said that all the new energy vehicle manufacturers have a headache. Due to the existence of three electric systems and batteries, the causes of vehicle fire are various. But no matter what the cause of the fire, the brand manufacturers are still the most injured. Even BMW, a car company, can’t escape the embarrassing situation of spontaneous combustion of new energy vehicles. Recently, according to foreign media reports, there are problems with the power batteries of BMW’s plug-in hybrid models. As impurities may be mixed in the production process, spontaneous combustion may occur after full charge. Meanwhile, it is reported that BMW has recalled 5000 hybrid vehicles in the United States because of the risk of battery fire. < / P > < p > it is reported that BMW has been affected by a large number of models, with a total of 26700 vehicles. One third of them have been delivered to consumers and the rest are at dealers. A BMW spokesman said it was possible that only one of the two suppliers had the problem of “impurities in the production process of the cell”, which is why only some cars have problems. In rare cases, these impurities can cause a short circuit in the cell. < / P > < p > in addition, foreign media have revealed that these vehicles are in danger of fire only when the battery is fully charged, which is why the recall statement also requires consumers to stop charging through the cable and to use the electric mode in a limited way, so there is no risk of fire. However, it is not known whether this defect has caused vehicle fire accidents. Last week, however, BMW reported three fires on its plug-in hybrid. Whether the two are related or not needs follow-up investigation and accident analysis report. < / P > < p > in fact, at present, not only BMW has suffered from the fire quality crisis of new energy vehicles, but Hyundai of Korea is also deeply trapped in the mire of vehicle spontaneous combustion. < / P > < p > after it was revealed by the media that its Kona pure electric vehicles had been burning for 13 times in succession, Hyundai announced that it would recall more than 26000 Kona electric vehicles and replace the battery of the whole vehicle after inspection without fully identifying the cause of spontaneous combustion. It is understood that Kona’s battery supplier is LG Chemical of South Korea. It has been revealed that Hyundai of Korea may consider replacing the battery supplier due to this incident, and it is more likely that the new battery supplier will be China’s Ningde era. Global Tech
