With the advent of midsummer, more and more robot batteries are involved in vehicle accidents. "As long as the temperature exceeds 35 degrees, the rate of vehicle anchorage is increasing rapidly. Those who are sick on the road are thrown away. Mr. Zhang of a Towing Co in Guangzhou told reporters.


      It is understood that all the leading causes of car parking, due to battery loss accounted for nearly 7 of the total, become the "culprit". In the face of such a huge car family, good use of car habits and regular self-examination is put on the agenda, for this reason, booli technical personnel and the public to share the experience of the battery for the field, and summed up the "one calculation, two look, three test" self-examination tips.

Case 1: import new cars two times without fire


Mr. Zhu told bloomer that the new imported Volkswagen Beatle car in his home was not on fire for the first time during the Spring Festival this year. At that time, Mr. Zhu used the "crossing the river dragon" to fire the vehicle spots, and there was no similar problem for some time.


Until the end of May this year, Mr. Zhu's new car was not fired again, and the situation was even more serious than before. "Even after a bit of fire, driving vehicles in the high-speed open dozens of kilometers, on the way did not open air conditioning and sound, stop one hour after the fire, once again ignition and no point, even with the" dragon "point after the fire, the situation is so, so I think the battery must not do. Mr. Zhu said as if.


In addition, Mr. Zhu added to Bo Li Mei, because the vehicle battery has no electricity at all, and the vehicle's burglar alarm is invalid.


Mr. Zhu later carefully studied the battery that had been changed, and knew that the original factory of the new car was equipped with ENERTEC battery, Mexico's Korean Daewoo accessories brand.


Case 2: a new battery suddenly doesn't catch fire


The same story about the battery, which also happened on Mr. Zhu, was more coincidental in the early summer of this year. It was not the Beatles but a new Volkswagen. Mr. Zhu believes that if the vehicle does not catch fire, there is no mistake in its operation, but "the quality problem of the battery itself". Mr. Zhu said, "there is really nothing to say about that thing. In the parking lot of Guangzhou Panyu, Decathlon stopped for a long day, and in the evening, the car could not fire. "


Mr. Zhu told bloomer, "I am not the first day to drive. I think my habits are very standard. There will be no mistakes. Is it equipped with automatic headlights, even if it does not turn off the lights? That is to say, in the ten thousand step, it is not to turn off the lights automatically, and it is impossible to remove the battery in one day, which is definitely the quality problem of the battery itself. Mr. Zhu added: "the battery must have been removed, and the remote control key can not be used to unlock the vehicle, or to lock the vehicle. It can only be operated by mechanical keys. According to reason, new vehicles and new batteries should not be in such a situation.


remind


Quality guarantee of large chain maintenance shop


In addition to brand names, the replacement of car batteries depends on businesses. It is understood that the current automotive supplies market, the battery industry generally exist shoddy, repair and renovation of waste batteries as new products sales.


Remind consumers that, although the 4S shop "original spare parts" has quality guarantee, but if you do not want to spend a lot of money to do small things, you can buy a large car chain repair shop, the confidence, the price is two. Once the unqualified battery is purchased, the best way is to immediately complain to the Consumer Council.


Knowing more than D


How to choose the car battery?


The first factor in selecting the battery is to choose the size of the battery; secondly, it needs to choose the right number of hours, and generally similar to Peugeot, the number of batteries for Ford, such as Ford, is around 60~65; if you are a ABB (Mercedes Benz, BMW Audi) fan Then your battery will have a good driving experience at least 75.


Mr. Zhuang suggested that on the basis of the original safety hours, a few additional hours should be increased to meet the daily and future demand for electrical appliances. For the battery, the size of the starting current is the key to judging the performance of the battery. The PowerFrame volt sharpening technology increases the grid conductivity by 70%, and the starting current is larger and more smooth.


Teach you three ways to self check battery

　First recruit: age


Master Zhang said to bloomer, the effective shelf life of the battery is ~24 months in December, the service life of the car battery is 2 years ~3 years, and the battery quality of different brands and models is not the same. In the summer, the owner of the car must pay attention to the expiration date of its own battery, and the owner who has passed the shelf life needs to pay more attention to it. Even if it can start the vehicle successfully, it needs to be detected in time. Battery is consumables rather than durable goods. When the shelf life is reached, the inner core material is in a "sub health" state, and there is the possibility of turning on the car at any time. Therefore, it is necessary to uphold the good habit of raising the car for 3 years.


Of course, the battery life of excellent quality starts with more times and has a relatively long time to use. It is undoubtedly an economic account for the owners of large electric power in the car to choose the leading battery. Mr. villa, a technical engineer, said that the main technologies in the Chinese market are: the gravity casting grid, the metal mesh grid, the exclusive research and development of the PowerFrame double volt positive grid patent technology of the United States Johnson automatic control. Gravity casting grids and metal grid grids are all traditional technologies. At present, small businesses in China still use these two technologies. The advantage of the PowerFrame double volt positive grid technology is that the starting current is increased and the corrosion resistance is improved.


Second: look at the car condition


In the day-to-day driving process, there are many details that imply that batteries need to be replaced immediately. This is closely related to the car owner's use of the car, Master Zhang gave a "seven attention" self-examination list, in these 7 notes, if the 3 items, the replacement of the battery must be put on the agenda:


Attention time: battery use over 3 years


Attention to ignition: when ignition is launched, it has been launched smoothly in the past, but it has to be played several times recently.


Attention to headlights: when driving at night, especially when the speed is slow, the brightness of headlights appears to be darkening than usual.


Attention to car: when listening to vehicle music, the sound quality is not as stable as before.


Pay attention to the window: the door glass is not used smoothly


Pay attention to double flash: Double flashlight is hard to open


Attention to remote sensing: the difficulty of opening the door by remote control


In the three years of active replacement, special attention should be paid to the timely replacement of batteries with larger current hours and more stable current when installing vehicle mounted equipment. With the advent of the Internet of cars, a car magazine pointed out that "the stability of the current is related to the overall uniformity of the grid and the quality consistency of each battery".


Third trick: measuring voltage


For the car owners who can intuitively observe the battery and the hands-on ability, Master Zhang gives more objective self-examination methods, and can judge by measuring the voltage by the multimeter at home. Voltage is the reason for driving the charge to generate current. The voltage is divided into open circuit voltage, charging voltage and discharge voltage. The open circuit voltage of the battery that represents 12V is generally above 13V. The test result is insufficient. 12.4V needs to be charged in time. The test result is insufficient. 12V recommends replacing batteries.


On the basis of safety considerations, Master Zhang gave the last suggestion, with a car with a car with a fire line, once the accident occurred, the owner of the car was begged for a fire to start the car and immediately replace it. Therefore, the daily maintenance of the battery is taken seriously, and the habit of "two years self inspection, three years to replace" a good automobile electricity use is the "King way" that truly allows the car to provide long - term service.
