In recent years, electric bicycles have won people's favor due to their convenience, quickness, and environmental protection. However, with the increase in the number of people using electric bicycles, complaints and disputes concerning electric bicycles have also been rising year after year. Among them, complaints about battery quality account for more than 75% of the total complaints for electric vehicles.
"China Quality News": There are four major hidden dangers of electric vehicle batteries.
Manufacturers fight price experts, the electric vehicle manufacturer's battery is generally provided by a professional battery manufacturer. The quality of batteries produced by different brands and different manufacturers is different, and the price is of course high or low. In order to share the big “cake†in the electric car market, some manufacturers have malicious competition, playing a price war on product sales, and cutting corners in the production process. Most of them use low-quality batteries purchased at low prices to assemble electric bicycles. In this regard, experts remind consumers that when purchasing electric bicycles, one cannot only unilaterally pursue low prices, but choose some brands with high quality and good market reputation.
Merchants earn money in accordance with the relevant regulations, the battery as the main component of electric vehicles, there is a corresponding "three guarantees" period. However, from the perspective of market research, some electric vehicle sales personnel do not have the battery maintenance expertise or related professional testing equipment. Generally, only adding some electrolyte to the batteries that fail during the “three guarantees†period can be considered as maintenance. pass. When the "Three Guarantees" period of the battery is over, consumers will need to buy new batteries for replacement. Some businesses simply do not admit to battery quality problems, and erode their responsibility to consumers on the grounds of consumer-induced damage. What's more, some businesses on the surface give consumers new battery replacements, but they use the oldest batteries for technical processing to fool consumers. Secretly, they asked the manufacturers for new batteries in the name of consumers to replace new batteries, and enjoyed the benefits. Therefore, consumers did a "big head."
Experts remind that, first of all, consumers want to buy electric bicycles to choose a fixed point of maintenance of the business or brand, the electric car after-sales service issues with the operator agreed in advance. Second, the battery "three guarantees" is a statutory obligation of the operator. The battery has quality problems during the "three guarantees" period. It is necessary to pay close attention to negotiating with the merchants to solve the complaints or to the relevant departments. Once again, when accepting repairs, replacements, etc., the relevant personnel must fill out the warranty on the warranty list and conduct a careful inspection of the replaced battery.
Less knowledge of maintenance It is understood that some consumers have problems with methods when using batteries. One is charging for a long time, thinking that the longer it takes to charge, the more electricity is enough. The second is the long-term loss of electricity, the voltage is close to the "red line" car did not move before charging. The third is charging when the temperature is too high or too low. The fourth is not paying attention to the regular inspection, maintenance and maintenance of the battery. Fifth, the correct operation was not performed according to the instructions.
Experts remind consumers that the length of battery life is not only related to the quality of the battery itself, but also related to the correct use of the consumer. Prolonged charging, prolonged loss of electricity and exposure to the sun will shorten the battery life. If the battery temperature is too low, the battery may have poor charging acceptance and insufficient charging. In addition, when charging, be sure to check the charging socket is loose, whether the line between the touch line, the use of the charger, wire diameter, voltage, etc. are consistent with the requirements of the electric vehicle instructions.
Disposable batteries Dispose of batteries for electric cars at random The batteries are usually lead-acid batteries. According to professionals, lead-acid batteries are mainly composed of lead, sulfuric acid, and some metals and plastics. The waste battery acid contains a large amount of lead. Random emissions not only seriously pollute the soil and water, but also cause diseases such as metabolism, reproduction and nerves. The relevant departments have made it clear that the electric vehicle sales industry must do a good job of recycling used batteries. In reality, some sellers regard waste battery recycling as an edgy wind, causing some of the old batteries to be collected by the “broken kingâ€. They dumped the lead-acid solution in used batteries and dumped the lead in the batteries and sold them to scrap collection stations.
Experts remind consumers that the number of used batteries for electric vehicles produced annually in the country is a considerable number. It is everyone's responsibility to protect the environment. On the one hand, operators must strictly abide by industry regulations and do a good job of recycling used batteries. On the other hand, consumers must not covet small profits and sell discarded batteries to small business hawkers.
Network Business Corps: Causes of Damage to Electric Vehicle Batteries The secrets of battery damage are complex and can be roughly classified into the following categories:
"Overcharging" causes damage to the battery. "Overcharging" is the cause of the charger first. Current electric vehicle chargers have a safe charging voltage setting. The charging voltage is generally set within 1.2 times of the standard battery voltage. For example, for a 48V battery, the charging voltage is set within 57.2V. During the discharging process of the battery, the voltage will gradually decrease. When the battery is charged again, the red light of the charger will light up, indicating that when the charging is performed, the voltage will continue to rise until it approaches or equals when the electric energy is continuously input into the battery. The green light of the charger will light when charging voltage, at this time, charging stops or trickle charge. If the charger voltage element fails, the charging will not stop, the charging current will be continuously input to the battery, the voltage will continue to rise, the result of the voltage increase will exacerbate the thermal reaction of the electrolyte, lightly the battery casing will be deformed ( Inflated), when it is heavy, the battery is charged.
"Loss of electricity" causes the battery to be damaged. "Loss of power" is a phenomenon that destroys the battery plate coating by forcing excessive discharge when the battery is low in charge and the voltage is low. Many users often use electric vehicles for charging for a few days, and some daily journeys exceed 60% of the nominal mileage of new batteries. It is necessary to know that a decrease in battery capacity will lead to insufficient battery voltage (undervoltage), and insufficient voltage will not be effective. Satisfy the basic voltage supply of on-board electrical appliances. When the voltage drops, the user is still using the electric vehicle, and the battery can not provide the normal voltage. Therefore, the battery undervoltage will appear “deficient†due to the load of the onboard electrical appliances. "Loss of electricity" will gradually strip lead from the battery plates until the plates are damaged.
The large current discharge caused by start-up, acceleration, and overload causes the battery to be damaged. The instantaneous current during start-up and acceleration of the electric vehicle is very large, generally reaching 20A-50A. According to the size of the motor power of the electric vehicle, the normal discharge current is generally controlled within 10A. it is good. As the instantaneous current is too large, the electrolysis reaction increases sharply, and the plate coating will inevitably be affected to a certain extent. As time passes by, the plate lead powder will gradually fall off due to the instantaneous large current pull, and the electrolyte will be blackened (lead powder To), the battery will be scrapped. Overloading will increase the discharge load of the battery. Long-term high-current discharge will directly affect the plate coating and accelerate the plate softening process. There is also poor road conditions that will make electric vehicles frequently brake and start. This is a factor that causes large current discharges. It is also worth mentioning that the greater the electric motor power, the shorter the service life of the battery, because the greater the motor power, the greater the discharge current, the greater the damage to the battery.
"Dehydration" makes the battery damaged and "lost water" is one of the basic reasons for the decrease of battery capacity. The majority of electric vehicles use maintenance-free lead-acid batteries. Many users will say that they are sealed and maintenance-free. Why is there a "water loss" phenomenon? The reason is very simple. Water is an important component in the electrolytic reaction of the battery. Once the battery is overcharged, large current discharge, increased internal resistance, short circuit, etc., it easily generates heat and forms water vapor. The water vapor is in the sealed battery box. Most of the time will be retained, but very few will be lost (as determined by the density of the battery case material), and as time goes by, the battery will have a "water loss" state. In general, the electric vehicle battery will have a “water loss†state for more than 6 months. The greater the motor power, the more severe the “water loss†state. Jiangsu News: Battery quality issues highlighted as complaint hot spots In September 2009, consumers Xu bought a brand electric bicycle. In November 2010, the battery was broken. Mr. Xu went to another electric vehicle maintenance department to replace four batteries. The use of two months is broken. The operator replaced the four “maintenance†batteries for Mr. Xu for free. It was broken in one month. The operator gave Mr. Xu another 4 “maintenance†batteries for the second time. On March 1, 2011, four "maintenance" batteries that had just changed for one month went "strikes." Mr. Xu explained to the operator that the operator explained: “Although it is a 'maintenance' battery, there is no quality problem because the weather is too cold this year. When the weather becomes warmer, the battery capacity increases.†Mr. Xu felt that Was å¿½æ‚ , and complained to the Municipal Consumer Protection Committee.
Since the beginning of the new century, the electric vehicle industry in mainland China has been developing rapidly, and in particular, the increase in the number of electric bicycles in recent years has become more significant. It has already entered the homes of thousands of ordinary families. However, with the increase in the number of people using electric bicycles, complaints and disputes concerning electric bicycles have also increased year by year.
Mainly include: 1, battery capacity decay, charging energy is not up to standard; 2, brake failure; 3, motor failure; 4, frame deformation; 5, manufacturers promise not to honor and so on. According to the reporter's understanding, in the electric vehicle battery quality complaints, most of the problems are that the electric charge does not go in or the battery capacity is insufficient, which is far from the usable time written on the manufacturer's instructions.
Cao Shengyue, Secretary General of Xuanzhou Consumer Association, said that electric vehicle batteries are generally provided by professional battery manufacturers. The quality of batteries produced by different brands and manufacturers is different. In order to engage in malicious competition among some manufacturers in the electric vehicle battery market, they played a "price war" and cut corners in the production process, resulting in uneven battery quality. In this remind consumers that the first choice to buy a car with a good reputation, good after-sales service, and a fixed point of maintenance business. Secondly, when the battery is subjected to maintenance, replacement, etc., the worker should be required to fill in the warranty form and the battery must be carefully inspected. Once again, when purchasing an electric car, pay attention to checking the warranty period and after-sales service commitment. If the product has problems within the warranty period, be sure to find the business in a timely manner, and do not delay the timing.
Netizen Xiaoliuzi: I bought a battery of ** (a well-known second-tier battery brand) in September last year. Marketers said that they can ride 100 kilometers. However, after spending two months, the electric vehicle can only ride 10 kilometers. At that time, it was thought that the weather was cold in winter. The reason is not too concerned about it. The result is that the sky is warm now, and it is still 10 kilometers. So I called it for free service. After the call is connected, let me call after-sales service. I call this after-sale service. A woman's answer call. She said that the 20A battery warranty is 5+4, which means that the five-month replacement, and another 4 months for the old, When I asked her about the after-sales service in Zhengzhou, she told me that she had been replaced for three months. I asked her: Is a large battery manufacturer's after-sale system different? She said yes, but also told me that my car is now riding 10 kilometers normal, tmd, my gas is nothing to say ... ...
User liling: The battery brand who dare not say that he is the best, because what kind of battery is useful and long-term, which group of battery is good, nobody knows, can only look at luck, can only say who The strongest strength.
