Battery warranty for one year six months or “strike”
Industry: new battery for six months after the renovation of damaged cells is norm
Mr. Zhang, the provincial capital to buy a brand of electric vehicle batteries, with no electricity for half a year, and had business commitments this year falls far short shelf life, Ms. Wang to buy another brand of bike, 10 months after Battery capacity is significantly less than to the business gave her a free replacement battery for a refurbished battery, very poor. Recently, this reporter received a lot of readers of the phone are reflected in electric car battery problems. Why do battery electric cars are more problems? Reporters have conducted some research.
readers to reflect:
After six months battery warranty for one year but can not charge
Mr. Zhang, the provincial capital in March last year to change a battery electric car, 36 volts, and spent more than three hundred dollars, but less than electric Juji six months, and I never ride no more, the battery can no longer charge. Zhang told reporters, when buying batteries, the business commitment to ensure that the battery can be used for one year. But when he hurriedly ran to find businesses, they found that the business has been empty. Mr. Zhang provided by merchants battery is definitely suspect a problem, when he asked around friends, you have the battery life of the warranty period of one year to challenge, “many of my friends and I have encountered the same problem a few months on battery not uncommon uphill climb. ”
The battery is new for the “old”
And compared to Zhang, Wang lucky. Last year, Ms. Wang bought a brand of electric car, 10 months later, the battery there is a clear lack of capacity, greatly reducing the mileage of the phenomenon, according to the standard warranty period of one year, Ms. Wang also rushed to the requirements for dealers new battery. Dealers said the can to replace the battery, but Wang found that not only looks new for some of the old battery, but after use, or the emergence of the same problem. Wang questioned the dealer, the dealer told her that after six months can only be replaced to maintain the battery, that is, the old battery refurbished “new” battery, which, Ms. Wang said it is difficult to accept.
Industry Secret:
There are two main reasons for reduced battery life
With these readers’ questions, the reporter interviewed the electric vehicle industry, the provincial capital, a senior person, the person told the reporter, resulting in reduced battery life of electric vehicles, for two reasons, one is the electric vehicles commonly used lead-acid batteries, life expectancy is only 500 charge and discharge; the second is the user overweight speeding, making the battery discharge current is too large, damaging the battery life. “Subject to technical constraints, the current widespread use of lead-acid batteries, can only charge and discharge 500 times.” Remind the public that the industry, if the electric car does not run out of battery power, do not frequent charging. Meanwhile, the electric car designed load capacity of only seventy to eighty kilograms, the design speed is generally about 25 kilometers, driving in this condition, in order to ensure a year of use, if the public often with people or cargo, road time and speeding driving, and will definitely hurt the battery life.
According to this industry sources, in general, well-known brands of electric vehicles, an optional battery quality is relatively good. Some brands of electric hybrid vehicles, the competition for the market, then to compete with low-cost, quality of the selected battery is not good. “Some battery manufacturers, care for immediate benefits, as cost savings, more money, they cut corners, so many electric vehicles use batteries, but the quality is related.” Six months later, the battery is the norm for maintenance
The source told reporters, according to national standards, the warranty period, the battery capacity falls below 60% of the original can be replaced, but the data must be obtained after a scientific test, that is not braking, not climbing without people, do not turn on the lights in the case shows the data, and electric car industry in accordance with the unspoken rules, businesses will change after six months to maintain battery, replacement batteries in electric vehicles, the business keeps on saying that the battery replacement for one year In fact, a new battery before the battery replacement for six months, half will be replaced to maintain the battery, so-called “maintenance battery” is actually the old battery renovation, the effect is certainly less than the original battery capacity and mileage, the industry revealed that this is their norm, the battery is a consumable, the factory did it out of cost considerations.
CASE reminder:
The two sides should be clear “three guarantees” responsibility
Reporters learned from the Provincial Consumer Association, complained of several categories of electric vehicles, which is part of a considerable number of complaints about battery capacity, reflecting the mileage and the product description promised a large gap, there are some after-sales Service does not regulate the lights and electric cars, carriages, speakers, batteries and other parts of the lock quality complaints. Relevant department official told reporters, because electric cars did not explicitly state the “three guarantees”, the end of 2006, Consumers Association of Anhui Province, Anhui Province Franchise Association Professional Committee of electric vehicles jointly issued a “consumer dispute resolution Anhui Electric Bicycle approach, “clearly sellers, special repairer, producers of electric bicycle repair, replacement, return (three packs) of after-sales responsibilities and obligations, the battery warranty period is one year, if there is leakage or less than 60% of capacity failure should be repaired and replaced, but the official said, for the exchange of in the end is to maintain the battery or new battery, and not clearly defined, should be subject to agreement between consumers and businesses.
Therefore, the Consumer Association reminds consumers to buy electric cars to try to buy a brand of electric cars, buy electric car, the dealer should be observed there is no special maintenance station. Some shops do not repair to the factory for professional staff training, technology is difficult to ensure, together with parts failure, service is difficult to keep up. Ask for a car to pay attention to after-sales service warranty card, invoice, and warranty for all parts written specifically to avoid future dispute. Also, do not believe in the verbal commitment to the business, maintenance, service agreements or written materials to be included in the invoice form, so that there is a dispute as evidence.
