Description
With the global trend of decarbonization, the production of new energy vehicles has risen sharply. As the main energy source of electric vehicles, people also have a lot of demand for charging stations. The voltage of modern charging stations is getting bigger and bigger, there are both AC high current fast charging charging stations and DC charging stations. Chifeng also provides circuit protection solutions for these applications.
EV Fuse is specially designed for the protection of vehicle system, EV Fuse is a full range over both overload and short circuit protection requirements.
EV Fuse features: It is fuse, but is different from the tradional g types fuse, designed to protect sensitive electric and hybird vehicle equipment, including high-voltage high-capacity batteries,
Power equipments, contactors, cables and other ancillary circuits, thus enhancing the safety of electrical systems. EV Fuse is able to provide as ow as 1.6 In rated current of the protection, suitable for
all kinds of over-current protection., can avoid the nuisance caused by cycle fatigue run. It is able to protect large fault current, large capacity, more efficient vehicles battery. It can meet the vehicle seseismic, impact resistant,
installation, Special requirements, such as resistance to high temperature, damp and hot. This series of fuses is suitable for the comprehensive protection of battery, circuit system and inverter in electric vehicles. The rated breaking
capacity can be 50kA.
This series of products meet the requirements of JASO D622 and ISO8820, AND gb31465. While meeting the above requirements, the current value of the fuse should also be modified to some extent. The maximum continuous load current
allowed by the fuse can be calculated by the following formula:
Ib=In.kt.ke.kv.kf.kb
Lb: Maximum allowable continuous load current
In: Rated current of the fuse.
Chifeng's new generation of CFB series high-speed semiconductor fuses adopts the North America round bolt structure in appearance. The fuses are designed according to both IEC60269 standard and UL248 standard. This series of fuses can perfectly protect your charging station.

FAQ
Q: What fuse should I use for the protection of the DC output side of the DC charging station?
A: Our CFB series high-speed fuses can effectively protect the output side of DC charging station.
Q: What are the advantages of CFB fuses?
A: Lower I2 t performance allows for quick response to protect devices from higher heat energy.
Q: Do I need an AC fuse if I use the DC fuse?
A: For the protection of the AC side of the charging station, because our fuse can be used for both AC and DC, we can use our CFB fuses or our special AC fuses.
