The function of the charging pile is similar to that of the fuel dispenser in the gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, and charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected with the AC power grid. The output terminals are divided into AC and DC, and are equipped with charging plugs to charge electric vehicles.
Safety and reliability must be considered in the design of charging pile. Therefore, safe and reliable protection devices must be used for overcurrent and overvoltage protection at input end, output end and communication interface. Here we recommend a high voltage and high current fuse spfj160 from Littelfuse, a leader in the fuse industry. This model is an ideal circuit protection solution for the DC output of the charging pile and has been widely used in the field of charging pile.
Spfj series is the first fuse listed in the ul2579 certification catalogue in the electrical industry, which is used to protect 1000VDC, 70-450a high voltage and high current equipment. Its design and manufacture meet the requirements of IEC standard 60269-6, and has passed VDE 125-450a application certification. These strict standards can ensure the safety of equipment and personnel, making spfj series truly a global product. 125-450a products provide J-Class housing size, which can save a lot of space for equipment manufacturers and greatly reduce costs. At the same time, Littelfuse of Shiqiang agent can also provide 1000VDC fuse holder for this series to meet the unique application needs of some customers.
The rated voltage of spfj160 is 1000VDC / 600vac and the rated current is 160A, which can meet the requirements of DC charging piles of various levels. Rated breaking current up to 200KA@600VAC perhaps 20KA@1000VDC , higher rated breaking current means that the fuse is less likely to burst under limit conditions, so it is more safe and reliable.
