电气传动系统损坏

电力传动系统是指使车辆运动的电气系统，包括电池、受电弓和牵引电机。碰撞可能会导致电动传动系统损坏，但主要是由于电流过大导致电气系统过载。如果操作不当和疏忽了电流表的测量，车辆可能会变得无法移动并着火。

Damage to such a powertrain subsystem can occur from collisions , but it is much more severe when caused by overloading electrical systems with excessive current , premature reverser operation, and traction motor overspeeding . Exposure to fire , or submersion in water, can also damage this subsystem.

High electrical powertrain damage can be catastrophic, potentially fully immobilizing the vehicle and setting it on fire.

Small amounts of electrical powertrain damage are also accumulated from normal operation of power sources and traction motors, which falls under regular wear and tear. The higher the current passing through traction motors, the more damage is inflicted. While this damage cannot be avoided, by operating the machines efficiently it can be reduced to a minimum.

Damaged electrical powertrains can be serviced .
