In recent years, with the development of new energy technology and the popularization of electronic products, new energy batteries, represented by lithium batteries, are increasingly dependent on people's daily life. However, the recent Samsung Note7, iPhone battery explosion and the serial burning of the Crab Island bus have attracted people's attention to new energy technologies. If the security problem is not solved, it will affect the arrival of the new energy era. Today, I will take you to talk about battery safety from the perspective of technology and relevant laws and regulations. With the rapid development of batteries and new energy equipment, while improving our lives, problems also arise. In the past year, battery accidents have occurred frequently: do you also worry about this, afraid of using mobile phones and new energy vehicles? First of all, for the continuous explosion and other accidents, we pay attention to the official reasons for the explosion: Samsung Electronics concluded that the battery was defective because Note7, which is the most concerned by the public, exploded frequently. On January 21, it was reported that the Samsung Galaxy note 7 smartphone battery survey showed that the battery had explosion defects, partly because the battery size did not meet the requirements, and other batteries had manufacturing problems. It is understood that Samsung started selling Galaxy note 7 in August last year. The battery is provided by its subsidiary Samsung SDI (Samsung SDI) and Hong Kong New Energy Technology Co., Ltd. According to the source, the battery provided by Samsung SDI does not conform to the size and cannot match the battery compartment of Galaxy Note 7, which may lead to overheating and fire. The battery defects provided by Hong Kong New Energy Technology Co., Ltd. are mainly related to manufacturing problems. It is unclear what the specific manufacturing problem is.
