Overcharge protection for electric motorcycles (e-bikes) | Case study of implementing Secondary protection fuse
- Protecting the battery and circuits in electric motorcycles
- Electric motorcycles, powered by batteries, have become increasingly popular worldwide in recent years due to their energy-saving features and low cost.
Electric motorcycles are equipped with high-voltage, high-capacity lithium-ion batteries, but they are susceptible to malfunctions due to impacts, high temperatures, etc., making circuit protection crucial. Dexerials develops and supplies Secondary protection fuse for electric motorcycle batteries.

Application
High voltage compatibility
Dexerials fuses meet the demands of high-power electric motorcycles, enhancing power output and long-range capabilities, and contributing to the realization of higher-performance electric motorcycles.
Safety in emergencies
When there is a high possibility that the battery may become uncontrollable due to some kind of problem, the charging/discharging circuit is cut off to ensure the safety of the battery.
Product characteristics
A heater is built into the element, allowing for arbitrary shutoff.
When the secondary protection IC detects an abnormality such as overcharging, it provides a "secondary protection" function that generates heat from the built-in heater and actively melts the fuse element to physically cut off the circuit.
Irreversible circuit interruption due to physical interruption
When an abnormality first appears, the circuit is physically cut off, preventing the battery from recovering once it has been compromised.
Compact and lightweight for automatic mounting
Dexerials fuses offer greater design flexibility for battery management systems (BMS) in power tools, garden tools, and cleaners where components must be mounted within limited space.
