Can the electric vehicle charger be dried after getting wet?

The electric vehicle charger can be dried after getting wet, but it must be disassembled to ensure the circuit board and electronic components are thoroughly dried. After drying, let it cool naturally before use. Below are specific details about electric vehicle chargers: 1. Classification of chargers: They can be divided into two main categories based on the presence or absence of a power frequency (50 Hz) transformer. Freight tricycle chargers typically use chargers with power frequency transformers, which are bulky, heavy, and consume more power but are reliable and inexpensive. Electric bicycles and electric motorcycles usually use switching power supply chargers, which are energy-efficient and highly efficient but more prone to failure. 2. Correct operation of switching power supply chargers: When charging, first connect the battery, then plug in the power supply. After charging is complete, first disconnect the power supply, then unplug the battery. If the battery is unplugged first, especially when the charging current is high (red light), the charger is very likely to be damaged. 3. Charger classification: Common switching power supply chargers are further divided into half-bridge and single-ended types, with the latter subdivided into forward and flyback types. Half-bridge chargers are more expensive but perform better, often used in chargers with negative pulses. Single-ended chargers are cheaper and have a higher market share.
