Why Doesn't the Electric Car Move on Rainy Days?

Controller speed limit plug short circuit due to water ingress. Below are the fundamental principles of pure electric vehicles: 1. Working principle of electric vehicles: Battery—current—power regulator—motor—power transmission system—driving the car. 2. Technical principle: Pure electric vehicles use motors to replace internal combustion engines, analogous to automatic transmissions. Traditional internal combustion engines can only generate efficient torque within a narrow speed range, which is why traditional internal combustion engine vehicles require large and complex transmission mechanisms. Pure electric vehicles do not need gear shifting devices during operation, making them easier to control. Compared to hybrid vehicles, pure electric vehicles use a single electric energy source, and the electronic control system significantly reduces the internal mechanical transmission system, also lowering energy loss and noise caused by friction of mechanical components, saving space and weight inside the vehicle.
