Supercharged Solutions for EV Charging
Littelfuse application expertise has helped to engineer some of the most advanced systems for EV charging stations. Let our team of experts show you how you can build safety, efficiency and reliability into your designs.
Whether you’re developing alternating current (ac) charging systems, which provide ac power to a vehicle’s on-board charger, or direct current (dc) fast chargers, which provide dc power to a vehicle’s battery system, you need a partner that can help you meet three key goals.
- Safety: Considering the use by the public year-round, it’s important that your EV charging equipment remains safe by minimizing the threat of electrical shock or other hazards.
- Efficiency: Power conversion is crucial for dc fast charging systems. Minimizing losses in power conversion ensures the maximum amount of power is delivered for charging the vehicle’s battery.
- Reliability: Once installed, you’ll want to ensure that your EV charging equipment remains functional for 10 or more years, even in the harshest conditions, to ensure you deliver the best return on investment.
With Littelfuse circuit protection, power control and sensing expertise, Littelfuse can help extend the life of your ev charging equipment and improve the system’s overall performance. Littelfuse offer guidance on what solutions work best for your unique system plus have insights on codes and standards for the EV market.

AC Charging Station
Although simpler in nature than DC chargers, AC charging stations safely deliver AC power from the electrical grid to the vehicle. Due to space and weight constraints in the vehicle, on-board chargers and AC charging stations are typically limited to lower amounts of power (22 kW or less), which means charging time is slow — taking several hours. These systems also rely on a vehicle’s on-board charger to enable the conversion of AC power from the grid into DC power to charge the vehicle’s battery. It is critical that proper measures are taken to safeguard both the charger and vehicle.

DC Charging Station
DC charging stations are designed to convert the electrical grid’s AC power into DC power that can then be fed directly into a vehicle’s battery system for fast charging — in 30 minutes or less. Because the conversion from AC to DC power is being done in the charging station, these units can provide higher levels of power (50 kW to 350 kW and beyond) to the vehicle than AC charging stations. Working with tens to hundreds of kilowatts of power, efficient conversion, reliability of the system, and user safety are critical.
