What are the reasons for the reduction of the battery capacity of the battery electric locomotive?

As the usage time of the battery electric locomotive increases, the battery capacity of the battery electric locomotive will inevitably decrease. What are the reasons for the decrease in battery capacity? Is there a way around this?

The reason for the reduction of battery capacity is that the battery itself is lost or damaged in various parts over time.

Some of them are not easy to handle or cannot be handled. For example, the battery is generally aging after several years of use and is close to the expected service life. In this case, we recommend replacing the battery directly. Another example is the vulcanization of the plate and the shedding of the active material of the plate. The former is not only a troublesome process, but also takes at least a few days, and even a few weeks if it is serious; the latter is almost impossible to solve. If the amount of shedding is small, Just clean it up. If there is a lot of falling off, it is recommended to replace the new battery directly. Some people may ask whether the polar plates can be replaced. First of all, most of the current batteries are not allowed to replace the polar plates. Secondly, the electric locomotive uses a battery pack. Random replacement of the polar plates may affect the consistency of the battery and lead to battery life. sharply shortened.

Perhaps the only thing that can be dealt with is the decrease in the density of the electrolyte, as long as the density of the electrolyte is adjusted to the standard value, or the electrolyte can be changed directly.
