Electric vehicles are low in price and easy to operate, and have become one of the main tools for more families to choose short-distance travel, even if the family buys a car, it is necessary to prepare an electric car for the family to use. On this more convenient, inexpensive and high-quality electric vehicle, there are many people who complain about it, such as less endurance, more problems in usual, and more problems on the road today.
There is a question that many car owners pay attention to, why is the electric car full as soon as it is charged, and two blocks of electricity will drop when the acceleration instrument display is displayed? This phenomenon may be encountered by every car owner, which does not occur in the early stage of battery replacement, and will occur in the later stage. Some netizens and customers consulted me, is this normal? Is there something wrong with the charger or is there a problem with the battery? How can we avoid or improve maintenance? Duo Bin believes that car owners usually need to know more about these maintenance knowledge, so that electric vehicles have fewer problems, batteries are used for a few more years, let's take a look.
Why is there an electric car that is full when charged, and loses two blocks when it accelerates, depending on the battery time
Everyone knows that electric vehicle charging is very long, like the new battery is generally 8 to 10 hours, used for more than a year of battery charging is about 7 to 8 hours, if there is a charge on the full situation, most of the reasons occur in the battery use time.
Why? First of all, to analyze the capacity and charging changes of the normal battery, the electric vehicle's power display meter power volt number is judged according to the battery capacity, the general power display meter will be determined by 5 cells, some are 4 boxes to display, from the left of the first cell capacity display 20%, 5 grids show 100%.
The battery's power display has a law, the new battery can reach 100% of the full charge each time, according to the full charge of 50 kilometers to calculate, a one-time full can run 50 kilometers, a grid of electricity can run 10 kilometers, the use of more than a year and a half of storage power can only reach 90%, the endurance will also drop to 40 kilometers. And so on, the later the battery stock is less, which is gradually declining according to the material and manufacturing structure of the battery, and the power display of the mobile phone that everyone is used to is the same.
We must understand that whether it is the battery of the electric vehicle or the battery of the mobile phone, it is designed to have a life, and it is based on the number of cycles of charge and discharge to determine the decline of the battery.
When the electric vehicle appears to be full of charging, no matter how to charge it, there are usually two situations, one is that the charger is faulty, so that the battery is not charged, and the second is that the battery has a problem, and the power storage is so much. When these two situations occur, it is necessary to go to find out the cause and carry out the "right symptom" to solve the repair.
If this is the case of a new battery, it is not normal, if it is a battery that has been used for about two years, what causes this situation to occur, how to solve the problem of extending the service life of the battery? Duo Bin will focus on analyzing these causes and solutions for you below.
As soon as the charge is full, the reason is in the charger or battery
The charging time of the bought car or the newly replaced battery is generally about 10 hours, and these problems need to be paid attention to when charging. For example, the charger plugged in a few minutes on the jump green light or plug in the direct unchanged light, charged for two or three hours on the full, fully charged riding about 10 kilometers without electricity, these phenomena, there may be a charger or battery failure, the car owner further to make a check:
Charger, line failure: When the owner is charging, first of all, plug in the charger directly unchanged light, continuous swing a few times and then recharge, generally is the charger line or charging port and line problems. Secondly, plugging in the charger can be charged normally, after a few hours the owner sees a green light to disconnect the power display fully charged, only to find that it is not much to walk during the ride and there is no electricity. The charger fully charged green light does not completely make the battery fully charged, there will be charger or line failure caused by insufficient battery stock.
Battery capacity becomes lower: whether it is a lead-acid battery or a lithium battery has a design life, with the loss of raw materials and the weakening of physical reactions, the storage capacity will be less and less, and finally it will affect normal use.
More than 80% of electric vehicles are installed with lead-acid batteries, the actual design life is about two years, the number of cycle discharges is 300 to 500 times, the first year reaches 100%, the first year and a half can reach about 80%, and it can only reach 45% in two years, and the battery will be reduced more and more severely with the longer the use time, and there will be a charge that will be full, the reason is that the battery declines.
As soon as the electric car accelerates, it loses two blocks of electricity, and there are factors such as batteries and riding methods
The power display of electric vehicles changes, which is the most accurate in cycling, when someone accelerates and finds that the battery drops 2 blocks of electricity, the owner will realize that it is not far to run. Usually, it takes more than 10 kilometers to run 1 block of electricity, and the entire 5 blocks of electricity must reach 40 to 50 kilometers after running. Now going down 2 blocks is basically a 60% drop in power, and the battery life will become worse. When you encounter this situation, the battery and riding style will have the most problems.
Battery problem: usually everyone rides an electric car to start the power basically no change, go down a grid of electricity to run 10 kilometers, a single acceleration will not lose power. If you find that the throttle will drop a block of electricity, it is related to the way of riding, if you find that a throttle will drop two blocks of electricity, the battery will have a large virtual power, there will be a smaller battery capacity or other reasons. The power-on gate loses power quickly, that is, the virtual power drops off, and the remaining 3 blocks are real electricity.
The problem of riding mode: Usually many car owners are accelerating at a uniform speed, the power has not changed, the current of the electric vehicle entering the controller and the motor will be small, the power consumption will be small, and the battery will have a certain protection. If it is habitually slammed with the throttle, the battery will discharge with a large current, and the fuel gauge will be faster in an instant, and when it returns to the average speed, the power will return to normal.
The electric vehicle is full as soon as it is charged, and two blocks of electricity are dropped as soon as it accelerates, and these points can be avoided by doing a good job
The above reasons will affect the electric vehicle charging on the full speed of the battery on the drop of two blocks of electricity, want to let the electric vehicle run far, do not affect the normal travel, these points are very simple to grasp, duo Bin will share with you one by one, to try, help you.
(1), charger attention point, the owner habitually put the charger in the seat bag, bumps will occur during the ride, put a cotton lining or fixed well below, charge the electric vehicle for a long time, the temperature of the charger is overheated, the loss of parts is too fast, the charging time should not be too long, the red light has changed, disconnect the power supply in the floating charge for an hour, use two or three years to consider the use of a new one, the battery will be better protected.
(2), battery capacity reduction or water loss, the capacity of the battery shrinkage has two reasons, one is the natural decline of normal service life, the other is that improper operation is easy to occur in use" overheating or power loss operation, so that the battery loses water too fast, declines too fast, too much water loss can be considered to add 5 to 8 ml of supplemental liquid page.
Note: Buy a new car or change the battery to replace the brand, good quality durable battery, how to choose it? The most important thing about heavy weight is durability, which can take more than one year more than the average battery. The car stops and rests for half or an hour and then charges, it should not be charged in the hot sun, the charging time should not be too long to fill, and avoid using a high-power charger to charge.
(3), the door is easy to consume electricity, young people love to like this operation, in fact, this method of operation has errors, the throttle consumes fast, uniform acceleration will make the battery more durable, the three major pieces are not easy to break, and electric vehicles are used longer.
The above multi-bin to everyone analyzed the electric vehicle charged full, an acceleration on the drop of two blocks of electricity, and the damage caused, these wrong operations do not pay attention to correct, battery damage will be faster, endurance will be less, the three major parts of the electric vehicle will be more likely to break, the charger will also be prone to charge and failure. If you want to avoid these situations, do the following three points that I share with you, the above problems will appear very little, and electric vehicles will run farther.
I hope that you read this content to help you, you can share with friends and family, solve these problems that often occur, let the electric car run farther, welcome everyone to leave a message in the comment area to communicate, have questions to raise, I will reply, remember to pay attention to me, like the Wide Hair Collection.
