Generally speaking, the service life of electric vehicles ranges from 3 to 5 years, but the batteries of electric vehicles need to be replaced in one and a half to two years. Recently, many users have reported that their electric vehicles still cannot run far after replacing the new battery. After testing, they found that the battery is good. What is the problem?
will tell you today that electric vehicles cannot run far in winter, but the battery test is fine. You can try these few tips. Most users feel that electric vehicles cannot run far because of the quality of the battery. However, the battery life of the electric vehicle is still not good after replacing it with a new battery, which may be related to these four points.
: The power consumption of electric vehicles increases
As the service life of electric vehicles increases, the electrical components are gradually aging. Like motors, controller , wiring harnesses, etc., these will increase power consumption. To give a simple example, the efficiency of converting electric energy into kinetic energy for an original 800W motor was as high as 90% when the car was new. After two years of use, the efficiency may be only 70% or even lower.
Suggestion: If the electric vehicle has been used for too long, the owner can trade it in for a new one. New electric vehicles must be paired with new batteries to achieve optimal battery life.
2: The charger is aging
Although car owners know that when the battery life of electric vehicles deteriorates, they should replace the battery with a new one in time, but many people do not realize that the charger has already aged. Some chargers even have threads falling off, but they are just tied with tape and continue to be used. This method will affect the charging and discharging efficiency. The electric vehicle battery may be undercharged for a long time, and the battery life of the electric vehicle will naturally be insufficient.
suggestion: When replaces a new battery, it can be equipped with a new charger. This can optimize the battery charging and discharging efficiency and avoid the situation where the electric vehicle still cannot run far after replacing the new battery.
3: More functional accessories
In the past, electric vehicles only had some basic configurations, but now electric vehicles are becoming more and more intelligent, including anti-theft, NFC card swiping to unlock, automatic locking, etc. As the number of functional accessories increases, the electric vehicle's power will also be consumed. As the vehicle is used for longer, the battery will naturally become less durable.
suggestion: It is not enough for to check that the battery is OK. You can go to the car dealership to check whether the efficiency of the motor, controller and other accessories has dropped. Only by "prescribing the right medicine" can the problem of insufficient battery life of electric vehicles be solved.
Four: Poor battery quality
Looking at the battery brands on the market, in addition to big brands such as Tianneng, Chaowei, Haibao, and Jingqiu, there are also many small and medium-sized battery brands, and even no-name batteries. Some car owners are cheap and choose unknown brands when replacing new batteries, or after-sales, turnover, and maintenance batteries. It is not surprising that electric vehicles cannot run far.
suggestion: should believe that "you get what you pay for". Batteries from big brands have better quality and after-sales service, and are more reliable to use. Although the price will be more expensive, in terms of comprehensive service life, it is actually more cost-effective to choose branded batteries.
Of course, as the temperature drops in winter, it is inevitable that the cruising range of electric vehicles will deteriorate, and this factor must also be taken into consideration. Compared with this force majeure factor, car owners still need to learn to check the root cause. Electric vehicles cannot run far, so don’t just blame the battery. Have you learned this?
