Why do electric cars ignite spontaneously

1. The internal wiring of the electrical appliance is aging. The only solution to this situation is regular maintenance. Don't go to the repair shop since you can't buy it. It's best to go to the repair shop every year. 2. Water enters inside the appliance. In this situation, be waterproof, try to beware of outdoor charging in rainy weather. The failure of charger and electric vehicle protection board is caused by overcharge, overcurrent, over-temperature, etc. This type of problem is basically formed by the failure of the two layers of the charger and the electric vehicle protection board (of course, some chargers do not have this function). This type of problem is obviously difficult to check, and the probability of occurrence is very Low, and new and old models are likely to happen, so it is proposed to be placed in the house as much as possible to guard against chain reactions. The battery is subjected to violent bumping and kneading, which are special conditions, formed by the external environment, and generally present the current accident situation. External reason: In fact, the number of spontaneous combustion of new energy cars does not occur more than that of traditional fuel vehicles. Why is it that we are so fascinated today? The reason is that we pay too much attention to the shortcomings of new things. Perhaps we do not accept this new thing from the bottom of our hearts. Internal reason: The new energy car itself has defects in its own skills, and the most critical and difficult technical bottleneck at present is the battery. Lithium batteries used in new energy cars, as far as today are concerned, are the same as car engines, and it is impossible to achieve 100% without problems. And because new energy cars use thousands of lithium batteries, as long as one has a problem, it will cause problems for all, which is tantamount to greatly increasing the probability of presenting problems. (At present, the safety of ternary lithium batteries is lower than that of lithium iron phosphate) In addition to the technical bottleneck of lithium batteries, there are problems in the battery management system. The current battery management system cannot effectively control a single cell, only a single module. In addition to the thermal management system, etc., there are certain technical deficiencies. These technical deficiencies may lead to the abnormality of spontaneous combustion of new energy cars or ineffective control.
