From 2010 till now, EV charging system has been in great progress, from the beginning outpower 1.9KW, charging time 12~18 hours; Then to 3 phases AC fast chargers output power 43KW, reduce the charging time to 4~6 hours; But even 4 hours, it’s not convenient to our life since people cannot wait so long time. Thanks to engineers’ hard working coming out DC fast charging station output power meet 400KW, the voltage from 400VDC increase to 1000VDC, it only takes 30mins, a coffee time, then we can continue enjoy the trip. Really great improvement to electrical vehicle.

Since ABPower is a company mainly focus on all fuses(Bussmann,  Littelfuse，Mersen,) study, here we are trying to summarize the main 1000VDC fast acting fuses in Bussmann for engineers’ reference.
