3 Key Goals of Electric Vehicle Charging Systems
Whether you are developing an alternating current (AC) charging system that provides AC power to an automotive onboard charger, or a direct current (DC) fast charger that provides DC power to an automotive battery system, Littelfuse can help build safety, efficiency and reliability into your design.
-
User electrical safety is of utmost importance when working with equipment that could expose people to electric shock or other hazards.
-
Power conversion efficiency is a key issue for fast charging systems and is measured by the power supplied to the vehicle versus the power drawn from the AC grid.
-
For infrastructure that is expected to be used for more than 10 years in harsh environments, system reliability is a key factor in ensuring return on investment.

JLS Series - UL Class J Fast-Acting Fuse
JLS series fuses save space and provide fast overload and short circuit protection for non-inductive loads. When used for motors or other inductive load devices, the rated current of the JLS series fuse must be increased to prevent the phenomenon of inrush current breaking the circuit.
JTD Series - UL Class J Time-Delay Fuse
Littelfuse® POWR-PRO® JTD_ID Indicator Class J Fuses provide intuitive blown fuse indication and maximum protection in a compact package. The compact Class J package is designed for circuits where space is extremely limited. The current-limiting, time-delay JTD_ID offers a patented true dual-element design for circuits with high inrush currents. The JTD_ID Indicator Fuse's superior operating characteristics reduce false fuse trips, and blown fuse indication reduces downtime and increases safety.
PSR Flush End Series - High Speed Square Shape Fuse
Littelfuse PSR Series Square Fuses are designed to protect power semiconductor devices such as diodes, triacs, IGBTs, SCRs, MOSFETs, and other solid-state devices commonly used in power conversion and power conditioning equipment. Variable frequency drives, inverters, UPS, rectifiers, and soft starters are typical examples of equipment equipped with sensitive power semiconductor devices that cannot withstand any line surges or overcurrents and require high-speed protection.
Ground Fault Relay
If current flows from the power source to the electrical grounding system via an undesigned route, a ground fault may result. This can be very dangerous to nearby personnel and may cause damage to equipment. Littelfuse ground fault protection relays provide the necessary protection against these situations.
UltraMOV Series - High Surge Current Radial Leaded Varistors
The UltraMOV metal oxide varistor series is used in applications that require high peak surge current rating and high energy absorption capability. UltraMOV varistors are primarily used in AC line voltage control products such as transient voltage surge suppressors (TVSS), uninterruptible power supplies (UPS), AC power taps, AC power meters or other products.
Silicon Carbide MOSFET
Optimized for high frequency switching of power converters. Very low gate charge and output capacitance, low gate resistance for high frequency switching. Ultra-low on-resistance, RoHS compliant, lead-free, halogen-free.
