Following the self ignition accidents caused by Tesla, NIO, and BYD in April this year, Tesla and NIO experienced a series of safety accidents in May. The safety issue of electric vehicles has become a focus of social attention. Although none of the above-mentioned accidents have caused casualties, they have triggered consumer distrust and panic towards electric vehicles.
The specific reasons need to be investigated, but this undoubtedly sounds an alarm for ternary lithium batteries that blindly pursue energy density. If the decline in winter driving range of pure electric vehicles is still a customer satisfaction issue, the continuous occurrence of pure electric vehicle self ignition accidents is a safety hazard, and with the increase of electric vehicle ownership, it is more likely to become a public safety hazard in the future. "On May 17th, an industry expert told 21st Century Business Herald reporters about the recent frequent incidents of electric vehicle fires.
In fact, Tesla, NIO, and BYD have had five accidents in China, which is just the tip of the iceberg that has surfaced. According to incomplete public data statistics, with the increase of ownership, the number of electric vehicle fire accidents in China has been increasing year by year in the past few years. According to statistics from relevant departments, there were over 40 electric vehicle fire accidents in China in 2018. According to the data collected by the charging station company, there were 11 incidents of electric vehicle fires from April 21st to May 10th alone.
On the one hand, the constant pursuit of higher specific energy and larger charging rates in power batteries has led to an increase in safety hazards; On the other hand, after several years of operation, immature new energy vehicles gradually enter a high-risk period. Calmly considering the rapidly developing electric vehicle industry over the past decade, battery safety remains the most fundamental challenge and an important threshold that requires high attention.
