Efficient power distribution modules and dependable disconnect switches improve Li-ion battery management in electric vehicles. This block diagram highlights components Littelfuse can supply for commercial and passenger EVs. Our solutions include capacitors, contactors, and dc disconnect switches. We also make high-voltage fuses specifically engineered to provide overcurrent protection in EVs.

EVs rely on dc–dc converters to step up or step down current from batteries. This block diagram shows the power conversion solutions Littelfuse offers. Our IGBTs and MOSFETs work with our gate drivers to ensure sensors, control modules, and dc motors receive the electricity they require. We also make diode arrays to keep noise from ESDs out of signals and thermal protectors to prevent overheating.

Ensure efficient and safe energy storage in EVs. Choose Littelfuse overcurrent and overvoltage protection devices shown on this block diagram to prevent short circuits and damage from current surges. Available solutions include high-voltage fuses, battery fuses, TVS diode arrays, and thermal protectors.

Onboard battery chargers convert alternating current from charging stations to direct current for electric truck, bus, and heavy-duty EV batteries. A block diagram highlights Littelfuse components that can serve as rectifiers, dc–dc converter gate drivers, and circuit protection devices for OBCs. Available products include thyristors, TVS diodes, and high-voltage fuses.

Traction inverters perform dc-to-ac conversion for drivetrain motors in EVs. A block diagram shows Littelfuse power converters vehicle makers can use, as well as devices that provide overcurrent, overvoltage, and overtemperature spikes protection to inverters and motor controllers. Available solutions include IGBTs and gate drivers, surface mount fuses, TVS diode arrays, and thermal protectors.
