求翻译：以上参数随着电池的老化、使用时极化内阻的变化，以及随着车辆行驶过程中很多耦合因素的存在，使得建立一个统一的电池的准确模型变得极为困难。是什么意思？

Above parameters as the battery ages, the changes in polarization resistance with time, and as many vehicles during the existence of coupling factors, makes the establishment of a unified battery of precise models have become extremely difficult.

The above parameters when used with battery of aging, and traffic blockage polarization as vehicles, as well as the changes in the process, there is a lot of coupling factor has allowed the creation of a unified battery accurate model has become extremely difficult.

Above parameter along with when battery aging, use polarizes the interface resistance the change, as well as along with the vehicles travel process in the very many coupling factor existence, causes to establish a unified battery the accurate model to become extremely difficult.

Above parameters when it is used as battery aging, changes of polarization resistance, as well as with the vehicle in the course of many coupling there is an element of, makes the establishment of a unified exact model of the battery becomes extremely difficult.

Above parameters as the battery ages, when use of the polarization resistance changes, and as a vehicle traveling a lot in the process of coupling factors exist, makes the establishment of a unified and accurate model of the battery becomes very difficult.
