What should I pay attention to when charging new energy vehicles in summer?

With the continuous development of new energy automobile industry, the number of automobiles is also increasing. According to statistics, as of 2065438+June 2009, the number of new energy vehicles in China was 3.44 million, accounting for more than 60% of the global total. With the increase in the number of new energy vehicles, the use of vehicles has become the focus of consumers' attention. So what should I pay attention to when charging new energy vehicles in summer? First, the temperature. In summer, the temperature is generally high, so charging for a long time in the hot weather with direct sunlight is easy to cause damage to the power battery, and even serious danger of spontaneous combustion may occur. Because the power battery is sensitive to temperature, when the ambient temperature of the battery exceeds 60 degrees, there is a risk of overheating or explosion. Therefore, when charging in summer, try to avoid charging in the outdoor sun for a long time, which is also conducive to preventing the paint from being damaged by exposure. Secondly, pay more attention to charging in rainy days. Although the waterproof design level of pure electric vehicles and charging piles is very high now, they are electrical equipment after all. If rainwater flows into the charging port, it is likely to cause a short circuit. Light damage to the car, heavy may endanger the charger. Especially in the case of rainstorm weather or the charging pile being submerged by rain, more attention should be paid. Finally, charging should be done every day. The charging of power battery should follow a principle, that is, shallow cycle charging. Don't wait until the power battery is exhausted before charging. Because if this method is adopted, it will damage the inside of the power battery, thus reducing the power storage capacity and affecting the cruising range. Therefore, I also reminded many times during driving, don't wait for the vehicle to lie down and charge. In addition, you should also grasp the time and times when charging. Both overcharge and undercharge will have a certain impact on the power battery. I don't know what other reasons you have. Welcome to leave a message for discussion! With the arrival of summer, the outdoor temperature rises gradually, and new energy vehicles will face the problem of outdoor charging. What should I pay attention to when charging new energy vehicles in summer? From the nature of charging, charging needs a suitable ambient temperature. In the process of charging, for electric vehicles, try not to go outdoors in sunny conditions and have high temperature for a long time. In addition, in the process of charging and fast charging, the electrochemical reaction rate of the battery is improved, and water is decomposed into oxygen and hydrogen, and even the battery is easy to charge. It will cause certain problems to the battery. Secondly, it is suggested to choose a place with such sunshade facilities as far as possible, and charge in a cool and ventilated place to ensure an adaptive temperature when charging and to dissipate heat for the power battery of the vehicle. Secondly, after the vehicle is driving at high speed, it needs to stand for a period of time, so as to ensure that the battery has an optimal charging opportunity. In addition, according to the charging timing of the vehicle, the charging time should not be too long. Generally, the battery charging time of electric vehicles should not exceed 5 minutes. 8 hours; When the battery is fully charged, unplug it in time. Although the charging pile has the function of self-power-off, it needs attention for safety. When charging the battery, if the charger plug keeps heating for a long time, immediately check whether the plug is short-circuited or has poor contact, and solve the corresponding problems in time. For new energy vehicles, it is necessary to correctly grasp the charging time and form the habit of charging in time after using the vehicle. At present, for new energy vehicles driven by electric energy, charging with charging piles is the main way to obtain energy supplement. The lithium-ion battery used in the power battery of new energy vehicles is a chemical battery, and its charging process is a chemical reaction process. If you don't pay attention, it may cause battery damage and even cause a burning accident. Entering summer is followed by hot and rainy weather. What should I pay attention to when charging new energy vehicles in summer? 1. heatstroke prevention and cooling. The optimum working temperature range of lithium battery is about 18-25℃. Working in this temperature range, lithium batteries have the most stable performance and the longest service life. The data show that the lithium battery is continuously charged and discharged for more than 50 times at the charging speed of 1C above 55℃, and the battery capacity is obviously decreased, and the battery life is shortened accordingly. When the ambient temperature exceeds 60℃, the battery will be in danger of overheating and explosion due to too high temperature rise. The battery will heat up when it is charged. If charged in direct sunlight, it will not only accelerate the aging of paint surface and circuit insulation layer, but also accelerate the temperature rise of the battery, resulting in poor heat dissipation, thus making the battery lose control of heat. Therefore, the vehicle should be transferred to a cool and ventilated place for charging in summer to avoid charging in direct sunlight. 2. Pay attention to heat dissipation. Power battery will also generate heat when discharging, and the battery temperature may be higher than when charging. If you charge the car immediately after use, it is likely that the battery temperature will continue to rise due to poor heat dissipation, which will damage the battery and even cause thermal runaway. Therefore, after using the car in summer, you should stop for about 30 minutes, so that the battery temperature can be fully cooled before recharging. 3. Less dosage and fast charging. During fast charging, the temperature rise of the battery is obviously faster than that of slow charging, which is more likely to damage the battery, reduce the battery capacity and shorten the service life. 4. Beware of lightning. Thunderstorms often occur in summer. Although charging in rainy days will not cause adverse effects on vehicles, charging in rainy days may cause vehicles to be struck by lightning, which will not only damage on-board electrical appliances, but also ignite vehicles. Therefore, charging is not recommended in thunderstorm weather. 5. Avoid low-lying areas. Sudden rainstorms often occur in summer, so when parking and charging, you should pay attention to choosing places with high terrain and smooth drainage, avoid low-lying areas, and avoid sudden rainstorms and vehicles trapped in water. 6. It is forbidden to fly line charging. On the one hand, if it suddenly rains heavily, flying wire charging is easy to cause short circuit or electric shock accident; On the other hand, the insulation layer of flying wire charging cable has a special capacity aging under the sun exposure, coupled with the friction with the outer wall, the aging is accelerated, which is easy to cause short circuit. 7. Avoid overcharging. When using, you must develop the habit of shallow charging and deep charging to avoid overcharging. Overcharging is very harmful to the service life of the battery, and it is also easy to cause battery burning accidents. In today's hot weather, electric vehicles should not be charged for a long time in direct outdoor sunlight. One is to better maintain the electric vehicle, and the other is to avoid the risk of battery damage or even spontaneous combustion. The battery is very sensitive to temperature during use. At present, the working temperature range of lithium batteries is -20℃~60℃. However, when the ambient temperature of the battery exceeds 60℃, the lithium battery will have the risk of overheating and explosion with the heating of the battery, but the probability of spontaneous combustion of the electric vehicle is extremely small. If an accident occurs, it is mainly caused by the aging of the line and short circuit in case of water. Both the vehicle itself and the charging equipment will have over-temperature protection, and it is equipped with BMS system to control voltage and power and coordinate the balance between supply and demand of the vehicle. Theoretically, the electric vehicle is very safe during charging, but it does not rule out that the car will cause damage such as line aging under high temperature exposure. First, we need to know the electricity price. The peak and valley electricity prices of general civil electricity are around 0.6 yuan and 0.4 yuan respectively. The price of State Grid DC charging station generally fluctuates between 0.4-0.9 yuan, and the general electricity service fee for third-party AC charging piles is between 1.2- 1.8 yuan.. Charging efficiency, the general efficiency of AC charging piles can reach 88%, and the DC efficiency is about 93%. New energy vehicles At present, the battery life of mainstream electric vehicles is between 100 and 500 kilometers, and the price of each charge is different. Take a 200-kilometer car for example. Charging piles. At present, the charging prices of mainstream charging piles range from 1.6 yuan to 1.8 yuan. It takes about 3 1 kWh to fully charge, and the prices range from 49.6 to 55.8. If you use a household charging pile, the price is about 0.58 yuan. If it is full, the price is about 18 yuan. It's still relatively cheap, and if you charge it with household electricity, the price in each city is different. In some cities, the price is only 50 cents, and it only costs 15.5 yuan to fully charge, which is really affordable. However, if the third charging pile is charged, the charging pile merchants will generally charge a few cents per kilowatt-hour. Therefore, for a new energy vehicle with a cruising range of about 150km, the cost from zero to 100% is only about 30 yuan, so it is quite cost-effective to calculate the electricity bill. Moreover, the engine and gearbox of the new energy vehicle are all electrically driven, so there is no need for maintenance, and only inspection is needed within a certain period of time. As we all know, the maintenance of gasoline vehicles is still relatively expensive, hundreds or even thousands at a time. From this perspective, it's really much cheaper. What should be paid attention to when charging new energy vehicles in summer-hidden trouble 1. Don't charge in the sun in hot weather, and don't charge immediately after driving. 2. Try to choose a cool and ventilated environment when charging. Too hot and humid environment is not conducive to the charging state, but also destroys the battery and reduces the life of the charger. 3, in the process of use, according to the actual situation to master the charging time and charging times. Overcharging, overdischarge and undercharge will shorten the battery life. 4. It is recommended to charge the battery every day to keep the battery in a shallow cycle state, so that the life of the battery will be prolonged. 5. When charging the battery, if the plug of the charger remains hot for a long time, it is necessary to immediately check whether the plug is short-circuited or has poor contact. You should pull out the charger, check whether there are oxides such as rust on the plug, and then take it out immediately. The charging of new energy vehicles is generally much more important, and this rain is especially so. In rainy days, it is best to have a shelter to cover the charging pile. First, turn off the lights. Nowadays, more and more users build private charging piles. These charging piles are generally located in underground garages, which is convenient for charging. Some drivers will turn on the light when charging, but remember to turn the light on or off when leaving or going home. Moreover, the electric car has no engine idling, so remember to check whether the vehicle power supply is turned off before getting off. In general, the lights and low-power electrical equipment in new energy vehicles are powered by on-board batteries. If it is turned on for a long time, it is easy to lose power. After a night, the power battery was fully charged, but the power was exhausted and the car could not start. Second, try not to turn on the air conditioner when charging the electric car, and do not use the on-board equipment. Many car owners will choose to wait in the car, but because it is hot in summer and cold in winter, can the air conditioner be turned on at this time? The answer is yes, but try not to drive. This is because charging and discharging electric vehicles at the same time will reduce the service life of the battery pack. Third, how to distinguish between fast charging and slow charging piles? Some new drivers don't even know about fast and slow charging jacks, let alone fast and slow charging piles. Many people will call fast-filled piles DC piles and slow-filled piles AC piles. Looking at the size of the charging pile gun head is the most accurate way to distinguish, the big one is fast and the small one is slow. But when you enter a huge parking lot, how to quickly distinguish between fast-filling piles and slow-filling piles? The easiest way is to distinguish by observing the volume. Generally, slow-filling piles do not need large transformers because of their small current and voltage output, so the volume of charging piles can be made very small. However, this method also has some limitations. With the continuous innovation of technology, many operators begin to design small-sized fast-filling piles, which can save more space for users. Take Aishenwei as an example, its company has designed mini charging piles and portable charging guns, among which the portable charging guns only need to be connected to household electricity, even saving the space for installing charging piles. In fact, if you want to save charging time, you should choose high-power electric piles. Each fast charging pile has corresponding power. At this time, we only need to observe the nameplate on the charging pile. The greater the voltage and current, the faster the charging speed. Of course, it depends on how much your car can charge. Don't think so much. Find the powerful one. That's right. Slow-filling piles also have power. Not every slowly filled pile has an output voltage of 220V, but the output voltage is 32A, with 16A. If your car is over 30 kwh, it doesn't matter which one you choose. After all, four hours is no different from five or six hours. But if your car is over 60-70 degrees, then you have to choose a high-power charging pile, because charging for one night is not enough. What should I pay attention to when charging new energy vehicles in summer? The new energy era is an era that we only have in modern times, and new energy vehicles have also come to our lives with a large flow. With the continuous maturity of new energy technology, its application in the automobile market is more and more accepted by consumers. With the strong support of the country, choosing new energy vehicles has become the choice of more and more car owners. Whether it is a pure electric vehicle or a plug-in hybrid vehicle, the charging problem is the most concerned topic for the majority of car owners. So what problems should car owners pay attention to when charging in summer? In hot weather in summer, electric vehicles should not be charged for a long time in direct outdoor sunlight.
