Can an Electric Tricycle Motor Still Run After Water Intrusion?
2 Answers
Electric vehicles can still be used after water intrusion. Water exposure affects electric vehicles in three main aspects: Damaging the controller: Although motor controllers are designed to be waterproof, their water resistance is generally not particularly effective. Water entering the controller can directly cause it to burn out. Short circuit at connections: If water enters the motor, it can cause short circuits at the connection points, especially in cases of deep water immersion. Battery damage: If water enters the battery compartment, it can directly cause a short circuit between the positive and negative terminals. The mild consequence is battery damage, while the most severe outcome could be the battery burning out or even exploding.
I've been repairing electric tricycles for over a decade and have seen countless cases of motor water damage. You're asking if it can still run? Generally speaking, if it's just been submerged, you might get a few weak movements out of it, but that's pure luck. Water ingress easily causes short circuits - at best frying the controller, at worst completely destroying the motor. I once had a customer who rode through a flooded area in the rain and kept using the vehicle, only to have the motor start smoking halfway, nearly catching fire. You must immediately cut power and dry it out - use a hairdryer on low heat or leave it ventilated for two days. Even after drying, don't rush to use it; get a professional shop to check the insulation. Water also accelerates internal corrosion, causing worse problems over time. For prevention, avoid flooded roads when possible, regularly inspect sealing rings, and adding a waterproof cover helps tremendously. Bottom line - if it gets wet, stop using it immediately. Safety comes first.
