Along with the development trend of new energy technology products in my country, the field of new energy vehicles is also rapidly improving. More and more battery-powered vehicles have entered the homes of ordinary people. Pure electric vehicles are bringing convenience to everyone’s transportation. Everyone’s safety. In the past, low-speed pure electric vehicles often produced safety accidents, which caused damage to the personal safety assets of customers. According to the latest news, BYD’s electric car sales reached 26,000 in the first 10 months of 2018, not to mention the total output of many other manufacturers. In 2017, my country’s pure electric vehicle production, supply and sales reached 770,000 units, and it is estimated that it will reach one million in 2018. Guanghuida believes that even if it does not reach one million, it will at least have a very large improvement over the previous year. As pure electric vehicles enter every household, it also creates some confusion for many customers, such as whether the driving force battery of pure electric vehicles will have an attenuation coefficient? How to maintain the driving force lithium battery in winter?
1. In winter, there is no need to overcharge and lose power when using lithium batteries
Everyone knows that, in fact, lithium batteries can complete the entire process of charging and discharging electromagnetic energy based on chemical changes. Then the temperature is more harmful to chemical changes, so the attenuation coefficient of battery power consumption in winter is more reasonable. Therefore, in the case of safe driving of pure electric vehicles in winter, we must pay attention not to let the driving power lithium battery lose power. When the power consumption is reduced to 30% or 20%, we can take time to recharge. If you run out of power, over-discharge will cause bubbles inside the battery, which is why everyone’s batteries will have flatulence.
2. The concept of fire safety for charging in winter must be high
To charge pure electric vehicles in winter, it is necessary to check the charging equipment. At this stage, there are three charging methods commonly used. There are 30kw fast charging piles and 5kw slow charging piles. Finally, it is the simple mode with the correct guidance equipment. Way 2 charging pile is out. Because fast charging piles are more expensive, the total number of popularization at this stage is far from everyone’s application regulations. Therefore, many people consider that the principle of distance is not easy to apply fast charging. Slow charging piles are more than fast charging piles. But it is far from reaching the total number prescribed by the application. Then there is a problem. In addition to the centralized lease of pure electric vehicles, manufacturers will basically build some charging piles. As an individual customer, buying a pure electric car is probably because he is optimistic about the charging effect of his family with 380V. Many people will choose to use method 2 for charging. Because this kind of equipment is simple and easy to operate, the price is low, and the size is small. , You can take it with the car. Many individual car buyers will use this type of charging pile for charging, so it involves the problem of independent wiring. If your power socket is not enough, some people will wire it without authorization. At this time, you must be clear about how powerful your pile is. , What is the amount of current? Is your cable diameter considering such a large amount of current? In long-term work, if you can’t consider it, there is a risk of fusing. You must not wire without permission. You must consult a professional professional before wiring. Technicians, many fire accidents are caused by short-circuit faults in the power circuit, except for the lithium battery itself, so we need to pay attention to it when charging.
