Other important considerations for new energy steam: 1. Check whether the power is sufficient, whether the braking performance is good and whether the screws are loose. Before leaving the car every day. If there is any fault, it should be repaired and eliminated in time. Only after the inspection is completed can the car start. 2. Turn off the power switch every time you stop, pull out the key, turn the gear switch to neutral and pull the handbrake. 3. Children should turn off the key switch when playing in the car to avoid danger. 4. Charging should be carried out where children can't reach. 5. When repairing or replacing the charging fuse of the charging part, the plug of the 220V power supply must be unplugged first, and live operation is not allowed. 6, maintenance or replacement of batteries, electrical appliances, must turn off the power switch after operation. 7. Before driving the electric car, check whether the door is closed. 8. In case of fire caused by accident or other reasons, turn off the main power switch immediately. What are the precautions for the maintenance of new energy vehicles?
Hello. For new energy vehicles, the most worrying thing is that there is no electricity on the road and it is urgent to charge. But also pay special attention to the service life of the battery. After all, for new energy vehicles, the battery is the power, and its life determines the service life of electric vehicles. But when it comes to electricity consumption, many people don't know whether to recharge the battery after it is used up or charge it on demand. Are these two methods harmful? Batteries? Today, let's take a look. First of all, as far as the battery types of electric vehicles are concerned, there are mainly lithium batteries, iron batteries, titanate batteries and lead-acid batteries on the market, among which lead-acid batteries are mainly used in mini-cars, while lithium batteries, iron batteries and titanate batteries are used in other mainstream vehicles. In addition, these three types of batteries all support the functions of charging and using. This will not affect the life of the battery because of the charging method. In short, it can be recharged anytime and anywhere at present, and there is no need to recharge it after use. As for the battery itself, its power consumption is regulated by BMS (Battery Management System), and the charging current is regulated by conditions such as state and remaining power, so as to protect the battery. At the same time, due to the different working environment of the battery itself, especially in winter, it is best to save electric energy for heating the battery and keep the battery charging in a good active state. Fast charging is bound to damage the battery. If it is a lead-acid battery, the damage is still relatively large, because the fast-charging current and voltage can easily cause the battery to heat and deform. If the fast charge mode is used for a long time, the battery will easily age. The electrolyte in the battery will gradually decrease, the battery life will be reduced and the battery life will be shortened. If it is a lithium battery, the damage will be less, but this does not mean that it can be recharged quickly every day. Lithium batteries have a high density. When the battery is charged quickly, it will generate great current and voltage instantly. With the passage of time, frequent use will reduce the reduction function of the battery and the number of discharge cycles of the battery will also decrease. Now with the development of technology, many pure electric vehicles have higher and higher demand for batteries. Some pure electric vehicles adopt ternary lithium battery and low temperature protection system to avoid large current input. Risk of battery overheating and failure. Under this low temperature protection, fast charging does little harm to the battery. However, in either case, it is theoretically not recommended to use the fast charging mode frequently, because the current and voltage in the fast charging mode are too large, which will affect the battery life or durability for a long time. It is still recommended to use it in an emergency. I hope my answer can help you, and I hope it will be adopted.
1. What's the difference between a new energy vehicle and a fuel vehicle? Fuel owners mainly maintain the engine system and change the oil and filter regularly. The new energy vehicle is driven by a motor, so the routine maintenance items such as engine oil, three filters and belts are naturally omitted, and it can be kept clean only by maintaining the battery pack and motor. It can be seen from the difference of routine maintenance items that the maintenance of new energy vehicles is simpler and easier than that of fuel vehicles. Second, what parts of new energy vehicles need to be maintained? 1, appearance: check the appearance of the vehicle. The visual inspection mainly includes whether the function of the lamp is normal, whether the wiper strip is aging and whether the paint is damaged. 2. Chassis: As usual, mainly check whether the chassis is loose and aging. 3. Tires: Because tires are equivalent to shoes worn by people, they are in direct contact with the ground. Due to the factors of road conditions, various failures will occur. Mainly check the tire pressure, cracks, trauma and wear. 4. Liquid level: antifreeze. Unlike fuel vehicles, antifreeze for electric vehicles is used to cool the motor and needs to be replaced regularly according to the time specified by the manufacturer (generally, the replacement cycle is 2 years or 40 thousand kilometers). In addition, gear oil is also called gearbox oil, which is also the oil that electric vehicles need to change frequently. 5. Engine room: that is, check whether the wiring harness in the engine room is aging or virtual connection. Remember, don't clean the inside of the engine room with water. 6. Battery: As the power source of electric vehicles, batteries are the most special and important components of electric vehicles. Third, how to master the charging time? When the red light and yellow light of the electric meter indicator light come on, it means it's time to charge; Only when the red light is on, stop running immediately and charge as soon as possible, otherwise it will lead to excessive discharge of the battery and seriously shorten its life. After fully charged, charge the battery for a short time, and the charging time should not be too long, otherwise it will lead to overcharge, battery fever and shortened battery life. In general, the average charging time of a battery is about 8- 10 hour. If the battery temperature exceeds 65 during charging, please stop charging immediately. What needs to be noted here is that we accurately grasp the charging time according to the actual situation, refer to the usual frequency and mileage, and grasp the charging frequency. Fourth, how to protect the charger and battery 1 and keep the charger ventilated when charging, otherwise it will not only affect the life of the charger, but also affect the charging state. 2. Avoid plug heating when charging, which may be caused by loose plug or oxidation of contact surface. If the heating time is too long, it will also lead to short circuit or poor contact of the plug, which will directly damage the charger and battery. So, once you find the above situation, please deal with it in time. 3. It is necessary to discharge the battery deeply at regular intervals, which is beneficial to activate the battery performance and slightly improve the battery capacity. 4. Charging every day. Most chargers actually only charge about 97%~99% of electricity after the indicator light shows full. The power difference of 1%~3% has little effect on the continuous operation ability, but it will form undercharge accumulation. So when the battery indicator shows that the battery is fully charged, try to charge it for a while. However, if the battery is charged every day, it can be in a shallow cycle state, which is conducive to prolonging the life of the battery. 5. It is forbidden to be in a power-off state during storage. Power loss means that the battery is not charged in time after use. If the battery is stored in a state of insufficient electricity, it is easy to be sulfated, and the lead sulfate crystal adheres to the electrode plate, which will block the ion channel, cause insufficient charging and reduce the battery capacity. The longer the battery is idle, the more serious the battery damage is. So even if the battery is idle, it should be charged once a month to keep the battery healthy. 6. In order to avoid heavy current discharge, electric vehicles should try to avoid slamming on the accelerator to accelerate when starting, carrying people and going uphill. Because the instantaneous high current discharge will produce lead sulfate crystals, which will destroy the physical properties of battery plates. Of course, some friends will ask, if there is a problem with the battery pack, will there be signs? During the use of electric vehicles, it was found that the continuous driving mileage suddenly dropped by more than ten kilometers in a short period of time. It is very likely that there was a problem with at least one battery in the battery pack. At this time, you should go to the 4S shop for inspection, repair or selection in time. Some friends will also say, why is it difficult to charge electric vehicles in winter? This is due to the influence of cold, and the power battery of pure electric vehicles will also be affected. Due to the influence of temperature, the activity inside the battery decreases, the power transfer effect is affected, and the cruising range is also reduced. It is precisely because of the reduction of transfer efficiency that the internal resistance of the battery pack increases, and it is impossible to charge efficiently and quickly, the charging speed decreases, and the electric energy cannot be fully charged at the same time. V. Maintenance precautions 1. What is the ambient temperature of vehicle charging? The ambient temperature range of vehicle charging is 0C-45C. When the ambient temperature is lower than 0C or higher than 45C, please try not to charge the vehicle. 2. Do I need to charge immediately when parking? Usually, we should correctly grasp the charging time and get into the habit of charging in time after using the vehicle. Due to the low ambient temperature in winter, it is recommended to charge the vehicle immediately after parking. 3. How to store the power battery? As a power source, the best charging environment temperature of power battery is 25℃. If possible, measures of keeping warm and preventing freezing can be taken in winter, such as putting it indoors and covering it with a warm tarpaulin. 4. Is it necessary to extend the charging time in winter? In winter, the charging acceptability of power battery is poor, which easily leads to insufficient charging and power, so it is necessary to extend the charging time of power battery. 5. What should I pay attention to when using a car in winter? In winter, the cruising range of electric vehicles will generally be affected, and the power consumption will be reduced, and the reduction range is generally 10%-20%, which is a normal phenomenon. Pay attention to the mileage of the day when using the vehicle. 6. Should the car be completely emptied when in use? When the electric vehicle is used repeatedly, it cannot be completely discharged. It is recommended to leave more than 20% power when driving. If discharged, it is very harmful to the power battery. 7. How to maintain the battery when the vehicle is not used for a long time? If you don't use the vehicle for a long time, you need to ensure that the remaining power of the vehicle is greater than 30%. It is recommended to replenish the power once a month when the ambient temperature is greater than 5C to maintain the healthy state of the battery. 8. What should I pay attention to when using vehicles in winter? In winter, the dynamic performance of vehicles is relatively poor. When the vehicle starts, carries people and goes uphill, try to avoid sudden acceleration, resulting in large current discharge, which is not conducive to the health of the battery. 9. How to care for the charging interface? The charging interface should be kept clean, and no water or other foreign matter can enter the charger interface, because it is easy to cause short circuit inside the charging interface of pure electric vehicles and affect the service life of the battery. 10. What should I pay attention to when going out in rainy and snowy weather? Pay attention to check whether the accessories of all new energy pure electric vehicles are in good condition and whether the batteries are fully charged before going out. In case of water accumulation in rain and snow, the hub center cannot be submerged by water, so as to prolong the life of battery and motor of pure electric vehicle. After rain and snow, special attention should be paid to the maintenance of electric vehicles. In Qin Ying, lubrication is also needed in winter. Scrubbing and lubrication of front axle, rear axle, middle axle, flywheel, front fork and rotation fulcrum of shock absorber of new energy pure electric vehicle.
