Lithium batteries are dangerous to charge at home. Let's take Yadi electric vehicles, Mavericks electric vehicles and Emma electric vehicles as examples. When charging the lithium batteries of these electric vehicles, do not charge them at home as they will cause safety hazards. Vehicle lithium batteries are filled with explosive and combustible substances, once the lithium battery is overcharged or surrounded by combustible materials, it will easily explode and catch fire after thermal runaway.
Precautions for charging lithium batteries
1. Sequence: When charging, first connect the battery, then turn on the power. After fully charging, first disconnect the power, then disconnect the battery and charger. Keep the key cover closed when connecting the battery to the vehicle.
2. Danger of surcharge: Unplug the charger in time after it is fully charged, and do not charge continuously for more than 8 hours.
3. Do not charge in a subzero temperature environment.
Recently, an electric vehicle exploded while charging in Hefei, causing serious injuries to two delivery drivers. The reason why such accidents often occur is, in fact, this. also has an important relationship with the battery technology installed in today's electric vehicles. It is true that electric vehicles have been developed for a long time and a large number of electric vehicles are now being produced. However, the huge breakthrough in the field of batteries is still relatively small, especially in the case of batteries used in electric bicycles. are actually different from many. Those used a few years ago are not very different and wet made greater progress in terms of battery life, but in terms of their essence, they are still chemical batteries. Such batteries themselves will present certain safety risks. .
Second, electric vehicles will explode when charging, which is also closely related to daily use, improper charging method and location. Chemical batteries themselves have many restrictions on use. For example, battery life is significantly shorter in winter, and too many recharges will affect battery life. There are many things to pay attention to when charging. This type of battery is also a significant reason why many communities and residential areas do not allow electric vehicle charging. There are still many such restrictions,so that incorrect charging methods or unstable voltage input are used during charging, or else. if it receives a lot of heat during charging, etc., the battery will be damaged or even explode.
Plus, events like this happen frequently, and another big reason is the ubiquity of electric vehicles. Nowadays, electric vehicles account for a high proportion in various cities, because they are more convenient to use and the cost is not very high. Basically every household can afford the cost of their use, so the ubiquity of electric vehicles is great. It has also become the current social norm. So many electric vehicles are used every day, with some of their own drawbacks, which will naturally lead to frequent explosions. However, this is relatively difficult to change. A means of transport environmentally friendly, inexpensive and easy to use.
So from my point of view, if we want to do our best to prevent such explosions, we need rapid development of battery technology, and we also need that users increase their vigilance and master correct use. Only by doing it correctly can we reduce the number of explosions and minimize the loss of people and property. The current technological progress is still relatively rapid, and many large companies such as BYD, etc., we are also working hard to develop more secure systems. batteries and electric vehicles still have a very bright future.
