There are often electric vehicle users complaining: the new battery replaced at the same time, why his electric vehicle battery can be "replaced every three years", while his own is "replaced once a year"? For this problem, my personal opinion is that the user's improper use leads to the shortening of the battery life, resulting in "one change a year", mainly in three aspects.
1. Charging
Some users prefer to recharge after use, and this method will shorten the life of the battery, causing it to overcharge or overshoot. Once the battery is damaged for a long time, the most direct manifestation is that the charging and discharging performance of the battery decreases, and it needs to be replaced with a new battery every year. Therefore, don't use it up and recharge it, learn to charge it properly to maximize the battery life, and "three years of replacement" is also possible, or even longer.
2. Driving
Some users like to use electric vehicles to carry people or pull goods, and this practice is more likely to damage the battery and reduce its lifespan. For example, if the same electric car is driven by a single person, it can last 50km when fully charged, and the battery can be replaced every three years, or even longer. If it is driving with people and goods, it can last up to 30km when fully charged, and the battery may need to be replaced once a year. So, from this point of view, different driving styles have a big impact on battery life.
3. Use the charger
Some users like to mix chargers, and this way will cause unstable voltage and current, charge the battery, shorten the service life of the battery, and even the problem of "replacing the battery once a year". Therefore, the correct way is to choose the right charger for charging, and do not mix chargers, so that the battery is likely to be "replaced every three years", or even longer.
In short, the same battery and different ways of using it will cause the battery life to be shortened. For electric vehicle users, adhering to the correct way of use and avoiding the above three wrong ways can reduce the situation of "one replacement a year" of the battery to a certain extent, and even "one replacement every three years", or even longer. Of course, the above is only a personal opinion and is for reference only.
