At nearly 2 o'clock in the morning yesterday, a lithium battery fire accident occurred in the home of a resident in Yichuan Four Villages, Putuo District, Shanghai, and it was confirmed that 3 people had died, and many media reported it, but they did not disclose the details. In just over two years in the Shanghai area, a battery burning fire has killed 33 young people!
The news received by this station shows that the brand of the battery car provided to the deceased for use is the domestic head enterprise, but the lithium battery provided by the merchant and is a large-capacity lithium battery that exceeds the standard. Battery car lithium battery repeated fires kill people, and it is difficult to stop, making people feel fear and uneasiness. Here, we make the following analysis of the accident:
First, lithium batteries are strictly forbidden to be brought into the living room for charging, but they cannot be stopped, indicating that the perpetrators have not paid enough attention to the harm of lithium battery fire and combustion. Why bring it indoors for charging? No conditions for charging the battery outdoors? These are not yet known. Although the harmful propaganda of lithium batteries brought into the room for charging is everywhere, it still has not been effectively paid attention to, resulting in a tragedy that is both a perpetrator and a victim.
Second, the quality of lithium batteries in battery cars is worrying. According to the survey, at present, hundreds of thousands of takeaway courier brothers in Shanghai use battery cars, and more than 70% of the batteries carried by them are mainly lithium batteries that exceed the standard (the new national standard stipulates that the battery voltage shall not exceed 48v). Since the charging conditions provided by the community and the service enterprises are insufficient and insufficient, it is inevitable to bring the battery into the home for charging. The terrible thing is that there is a problem with the quality of the lithium batteries that are used in large quantities and the chargers that provide charging for lithium batteries. Due to the lack of effective market supervision, inferior lithium batteries and chargers are rampant in the market, laying hidden dangers for lithium battery fires.
Third, whether the lithium battery cells decommissioned by new energy vehicles and the lithium battery cells that are disassembled or scrapped by the equipment can be assembled into battery car power lithium batteries, there is currently a legal blind spot. In recent years, a large number of new energy vehicles have retired lithium battery cells and various starting equipment disassembled lithium battery cells into the market, the number is not cheap, and the battery car demand for large-capacity power lithium batteries is huge. Because this kind of waste lithium battery cell is assembled into a battery car power battery with cost-effective advantages, the market has formed a complete industrial chain. The whole process from dismantling to assembly to sales is lucrative, coupled with the lack of supervision and regulation, and the different attitudes of various places to the production and sale of this power lithium battery disposal, resulting in inferior lithium batteries being banned repeatedly. Waste lithium battery cells assemble battery power lithium batteries for battery cars, and the silence at the legal level has found an excuse for those who are lawbreakers to produce and sell.
Fourth, the waste lithium battery cell is assembled into a battery car power lithium battery and there is indeed an unshirkable responsibility. After several years of use, the life of the waste battery cell has expired or even expired. It is worth mentioning that the battery car use environment is extremely harsh, sun and rain, high temperature baking, low temperature torment, bumpy road, but also to withstand high rate discharge, high current charging of the day such a number of repeated torture. Under the test of such an environment, even the new battery must accelerate its life span, not to mention the old battery that has been used for six or seven years. However, driven by interests, the entire production of lithium batteries in assembled battery vehicles is unavoidable in its simple process and the effectiveness of the battery protection system.
Fifth, the deformed sales method provides space for sales stores to illegally operate inferior lithium batteries. Vehicle manufacturers have long adopted the model of naked car sales, which provides convenience for merchants to purchase inferior high-capacity lithium batteries and carry them on the whole vehicle. If it is said that the manufacturer provides the whole vehicle equipped with the battery to the merchant, and the state explicitly stipulates that the "one car and one electricity" method is used, so that the vehicle and the battery can enter the market for sale, then the inferior battery cannot flow into the market. However, now that the two channels of vehicles and batteries have entered the market, it is inevitable to sell vehicles and batteries under the drive of maximizing profits.
Sixth, the online booking platform is outside the supervision, which has caused conditions for the flood of inferior large-capacity lithium batteries, and also brought hidden dangers to the introduction of inferior large-capacity lithium batteries into the home for charging. Takeaway express delivery operators, hired riders and battery cars used by riders, are solved through a third party. This operation removes the burden of huge personnel use and equipment purchases, and improves operational efficiency. A third party outside the online booking company, providing battery car rental for riders, and riding riders to solve batteries by themselves, are aimed at maximizing benefits and efficiency, and the market cannot fully provide the corresponding resource allocation, and the battery assembled from this waste lithium battery cell has a cost-effective advantage. It is reported that at present, more than 300,000 riders in the city use battery cars, most of which are mainly battery cars provided by third parties for leasing and self-purchase. The centralized charging equipment provided by the market is incomplete and sufficient, resulting in the phenomenon of individuals bringing batteries into the home to charge.
The number of accidents that kill people due to burning fires in lithium batteries of battery cars last year exceeded 10,000 in the country, and showed an upward trend. If the phenomenon of heavy use of inferior lithium batteries is not curbed, the tragedy will continue to occur.
