電氣動力總成損壞

電氣動力總成是指使車輛運動的電氣系統。包括電池、集電弓和牽引馬達。碰撞可能會造成電氣動力總成損壞，但更多是由於電流過大導致電氣系統過載。如果操作不當、忽略電流表、時速表讀數，最終可能導致車輛會變得無法運作並著火。

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 .
