When it comes to winter car use, friends around me basically know a little bit about it. Of course, more senior old drivers even have a "classic" routine, but when it comes to new energy vehicles, they seem to be ignorant. In the future, you will undoubtedly be the owner of new energy vehicles, so it is necessary to know and understand the different precautions of new energy vehicles in advance. After all, some old traditional knowledge needs to be updated and some rumors need to be ended. New energy vehicles are mainly divided into plug-in hybrid cars and pure electric cars. When it comes to plug-in hybrid cars, you will feel that the use of vehicles in winter is no different from that of fuel vehicles. If there is no charging environment, the plug-in hybrid cars can only be used as "fuel electric hybrid cars" or "fuel vehicles". In addition to the clever use of "kinetic energy recovery system", the difference in other aspects is really small. However, if there is a convenient charging environment or habit, you must pay attention to it when charging in winter. At least it is the same as the car at this point. Before charging, you must ensure that the charging gun head is dry and clean, especially when you use it outdoors in public. After all, the current situation of littering the gun head is often seen. In terms of charging, no matter in that season, when charging plug-in hybrids or pure electric vehicles, it is more recommended to use AC slow charging for new trips, which can make the service life longer, but you will feel that slow charging is too slow and anxious. However, if there are good charging conditions and habits, night charging can be completely achieved, while DC fast charging is usually used occasionally in emergency and long-distance travel. In addition, if there is a charging setting, it's better. The pure electric vehicle also eliminates the hot car link. At present, the mainstream pure electric vehicles are usually equipped with the function of battery pre heating, or directly a more intelligent temperature control management system, so we don't need to worry about the phenomenon that the lithium battery can't be charged in the winter, and it's with the addition of these functions that the battery attenuation of pure electric vehicles in the winter is not so serious, and it's impossible to happen like a crouching nest. Therefore, some car owners will customize the charging scheme according to their own use conditions, but some "obsessive-compulsive" car owners prefer the diligent "on demand charging". In fact, this habit of "always keep the power" is bound to be very good, at least to avoid the daily "mileage anxiety" worry. Although some people say that charging too frequently also has disadvantages, after all, in trickle or pre charging state, there will be power loss, so frequent charging will have part of the economic loss (just like the amount of gasoline volatilized from the fuel tank mouth is a meaning), but this small loss can be completely ignored. When it comes to hot cars, many of my friends subconsciously think that plug-in hybrid cars are needed, while pure electric cars are not. In fact, for pure electric vehicles, especially when they enter the temperature of 0 ℃ earlier in the north, if it is not for overnight charging, when the pure electric vehicles are placed overnight, it is better to "heat" them for 30 seconds to 1 minute before using the next day. After all, after the whole circuit is preheated after power on, it is beneficial to extend the service life of the parts in the vehicle. In addition to making the circuit system of the whole vehicle have a preparation link, the vehicle should accelerate slowly after moving, which is similar to the fact that the fuel vehicle just started. At the same time, if the power of the whole vehicle is less than 25%, remember not to turn on the warm air and "floor oil" to accelerate rapidly, because in this case, the sudden excessive current will cause certain damage to the battery diaphragm. As the core component of new energy vehicles, especially for pure electric vehicles, in winter, due to the higher overall power consumption, we should keep the battery in a normal cycle state, so it is necessary to charge frequently in winter. Usually, the discharge depth of dynamic battery is 70% - 50% Time charge is the best, which will make the battery life and performance better. New travel also suggests that you should avoid frequent deep discharge as much as possible, but it is OK to occasionally recharge the battery by a proper deep discharge. In addition to the correct theory of charging and discharging batteries in winter, especially after the snow in the north, if the pure electric vehicle stops on both sides of the road, it is recommended to clean the chassis (where the battery is located) when conditions permit. After all, the sanitation workers use snow melting agent when cleaning the snow, and this chemical also has a certain corrosive effect, although the pure electric vehicle bottom The plates are processed before delivery, but it is better to clean the chassis. In winter, rain and snow often occur, and the road is easy to freeze, which affects the safety of driving. At this time, the advantages of new energy vehicles are highlighted. We all know that it's easy to lose the grip and sideslip when we step on the accelerator or brake on the slippery road, while the new energy vehicle is equipped with a "kinetic energy recovery system", which can usually adjust the strength of the third gear. If we set the level of "kinetic energy recovery system" to the strongest level on rainy and snowy roads in winter, it will not only reduce the number of times to step on the brake, but also recover part of kinetic energy every time "automatic deceleration", but the core role is to help reduce the speed steadily to ensure safety, which will be very useful after use. In the hybrid car, some "old drivers" can also use this to control the speed, so as to achieve the purpose of fuel saving. Make complaints about the electric car in winter. The electric car is always the focus of the "keyboard warrior". It also laughs that every electric vehicle owner is wrapped like a bear in winter. In fact, the new winter trip is actually tested in winter. For the pure electric vehicle at present, the effect of constant temperature on the whole life is not big. You can use warm air to drive safely. If it's not enough, you can also turn on the warm air to keep warm. At this time, as long as you keep the speed, do not step on the accelerator with big feet. It must also be explained here that the speed of the car can affect the overall endurance mileage more than the warm air. After all, the power of the warm air (resistance wire) is fixed. As long as it is adjusted to a fixed gear, the power consumed is the same. At the same time, the car can be closed for a while to save power if it is not cold. Therefore, the influence value of the warm air is only related to the opening time. ▲ the influence value of warm air on the endurance mileage is not as frightening as that of Internet transmission. This is a reasonable range and the vehicle speed is totally different. If you drive frequently and intensively, it is not difficult to find that the average power consumption of 100 kilometers will increase accordingly. At this time, even if you do not turn on the air conditioner or warm air, the remaining endurance mileage will also drop very fast. In fact, this principle is the same as the strength of the throttle control of the fuel truck handle, so the heating fee does not cost electricity actually has nothing to do with the speed. In the end, in addition to the above-mentioned notes related to its own characteristics, the winter use and maintenance of plug-in hybrid cars are basically the same as that of traditional fuel vehicles, while the basic problems of pure electric cars such as replacing glass water in winter, anti fog in winter and inside the car are also the same as that of fuel vehicles. Apart from the same winter use and maintenance as traditional fuel vehicles, in fact, new energy vehicles have a set of exclusive solutions in terms of battery pack, charging, hot car, driving and cleaning according to their own characteristics and three electric systems. In addition to these small skills that must be learned, the rumors about the great influence of warm air on the endurance have also been ended, as long as they are positive Constant temperature heating and size are often used, so you can use it safely. In addition, due to the advantages of battery constant temperature technology, there is no need to worry about charging and battery performance degradation in winter. If you want to use a pure electric vehicle to run in the middle and long distance, it's better to do the strategy of charging pile in winter, and at the same time, you need to frequently charge to eliminate the anxiety of mileage.
