When repairing electric trailers, battery problems are indeed one of the more common and prominent faults, but they are not the only common problem. The following is an analysis of the prevalence of battery problems and related situations:
Prevalence of battery problems
1. Battery attenuation and charging problems
Battery capacity attenuation is one of the common problems of electric trailers. For example, some electric vehicles will not be fully charged or charge slowly after a period of use. Especially in low temperature environments, the charging efficiency and endurance of the battery will be significantly reduced.
2. Battery bulging and deformation
Battery bulging is physical damage caused by excessive internal pressure, which is usually related to overcharging or battery aging. In this case, the internal structure of the battery is damaged and usually cannot be repaired and can only be replaced.
3. Damage to individual batteries in the battery pack
The battery pack consists of multiple battery cells, and damage to one of the battery cells may cause the performance of the entire battery pack to deteriorate. In this case, it can be repaired by replacing the damaged cell.
4. Deterioration of battery performance in low temperature environments
In winter, the charging speed and endurance of the battery will be affected by low temperatures, resulting in longer charging time and shorter driving range.
Are battery problems the most common?
Although battery problems are a common problem in electric trailer repair, they are not the only common problem. For example:
Charging system failure: Undercharging or overcharging may shorten the battery life.
Electrical system failure: The electric trailer’s electrical system, such as the motor and controller, may also fail, but these problems may be less difficult and less expensive to repair than battery problems.
Mechanical structure problems: The chassis and mechanical structure of the electric trailer may also be damaged due to the harsh operating environment.
Battery problems are indeed one of the common problems in electric trailer repair, especially in low temperature environments, where battery charging and endurance problems are particularly prominent. However, the repair problems of electric trailers are not limited to batteries, but also include charging systems, electrical systems, and mechanical structures. Therefore, although battery problems are common, they are not the only maintenance focus that needs attention.
