Why does an electric tricycle not move when it has power on rainy days?

The reasons why an electric tricycle does not move when it has power on rainy days are problems with the handlebar, issues with the brake switch, or a blown fuse. Introduction to electric tricycles: An electric tricycle (Electrically-operated-tricycle) is a three-wheeled transport vehicle powered by a battery and driven by a motor, used for carrying goods or passengers. Introduction to the battery: Electric tricycles use tubular high-capacity, left-right lined, deep-discharge, traction batteries that can meet the requirements of continuous discharge for long working hours. The battery can normally be used for two years without a decrease in capacity. Introduction to the motor: The electric tricycle motor uses a DC series-wound traction brushed or brushless motor. The motor is equipped with a speed-regulating and power-increasing device, which is not easily damaged under normal use and ensures strong power output.
Last time I rode an electric tricycle in the rain, I encountered a similar issue. The vehicle had power but wouldn't move no matter how much I pressed the throttle. After inspection, I found that the controller had short-circuited due to water ingress, causing signal interruption. The wire connectors were rusted, and rainwater could easily oxidize and loosen them, potentially affecting the entire circuit. Another possibility was that the motor got damp, with the internal bearings seizing up and unable to rotate—this is related to regular maintenance, like not applying waterproof sealant in time. Alternatively, the brake system might have gotten wet, causing the brake sensor to misjudge and prevent operation. Muddy roads in the rain can also easily clog the wheels. I recommend first pushing the vehicle to a dry place and checking if the controller and main wire connectors are wet. Try drying them off simply; if that doesn’t work, take it for repairs. For prevention, park the vehicle indoors to avoid rain exposure, perform regular rust-proofing treatments, and try to minimize using electric tricycles in the rain—safety first!
