Tricycle Battery Connector Melt Under High Current Fix
Melting battery connectors is a dangerous high-current fault of electric tricycles, which not only affects normal vehicle operation but also easily causes short circuits, spontaneous combustion and other safety hazards. The fundamental reason for connector melting is excessive contact resistance under high-current operating conditions. When the tricycle starts with heavy load, climbs slopes or runs at high speed, the battery outputs a large instantaneous current. If the battery connector is loose, oxidized, rusted or covered with dirt, the contact area between the plug and socket will decrease, resulting in sharp increased contact resistance. According to the Joule heat principle, high current passing through high-resistance parts will generate a large amount of heat in a short time, which exceeds the heat dissipation capacity of the plastic connector shell and metal terminals, eventually causing melting, deformation and even burning of the connector.The first step to fix melted connec
