After entering the winter, some electric vehicles may encounter a situation where they are not fully charged and the battery is not durable. In this regard, some users have raised such a question, that is, the electric vehicle is not fully charged, and the battery is not durable, what are the reasons?Actually, in my personal opinion, there are three possible reasons.
1. Low temperature affects battery performance and charging effect.
First of all, due to the low temperature in winter, the overall charging effect of the vehicle will be poor, and at the same time, the battery performance will be reduced to a certain extent. At this time, it may be that the electric vehicle is not fully charged and the battery is not durable. For this situation, you don't have to worry too much, as the temperature rises, the battery life will gradually increase.
Second, the single battery is damaged, which affects the charging of the whole vehicle and reduces the durability.
Secondly, for electric vehicles, if a single battery is damaged in winter, it will affect the charging of the whole vehicle, and the most direct manifestation is that the charging is prematurely tripping the lights, but it is not actually full. Taking a 100% battery as an example, a single battery may only be charged to 50% to 70% or even lower after it is damaged. In addition, from the perspective of battery life, if a single battery is damaged, then the vehicle battery life will not be able to run far, and the durability is poor.
3. The battery has been vulcanized and the charging performance has declined.
Finally, there is also a possible reason that the battery has been vulcanized and the charging performance has deteriorated. Because in winter, many users place the electric vehicle for a long time or the battery has been used for many years and there is an aging problem, then there may be vulcanization failure, and the most direct manifestation after vulcanization is the reduction of charging efficiency, the battery is not fully charged, and the battery life is not durable.
In short, electric vehicles in winter are not fully charged, and the battery is not durable, which is generally caused by the above three reasons. For users, no matter what the cause is, it needs to be solved accordingly. Among them, if it is caused by the first reason, after the normal temperature rises, the performance of the battery can be restored to the same as before. But if it's the first.
Two or three reasons, then it is necessary to replace the new battery in time. Of course, the above is only a personal opinion and is for reference only.
