How Does a Fuse Protect the Battery Charger From Overloads?
A fuse protects the battery charger from overloads by acting as a safety device. When the current flowing through the charger exceeds the fuse’s rated limit, the fuse melts or breaks the circuit. This interruption stops the flow of electricity, preventing damage to the charger and the battery. The main components involved include the fuse, the battery charger, and the power source.
When current flows through the charger, it usually stays within the fuse’s limit. If a fault occurs, such as a short circuit, the current spikes. The fuse detects this spike quickly. It operates based on the principle of heat generation due to electrical resistance. When the excessive current heats the fuse beyond its threshold, the metal inside melts. This melting disconnects the circuit and halts the power.
By stopping the electricity flow, the fuse protects both the charger and the connected battery from potential failure or overheating.
