Product Overview

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 traditional g type fuse, designed to protect sensitive electric and hybrid vehicle equipment, including high-voltage high-capacity batteries, power equipment, contactors, cables, and other ancillary circuits, thus to enhance the safety ofelectrical systems. EV fuse is able to provide as low 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 capacityr, more efficient vehicles battery. it can meet the vehicle seismic, 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 ofproducts meet the requirements of JASO D622 and IS08820, 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:

lb=In.kt.ke.kv.kf.kb

Lb: Maximum allowable continuous load current

In: Rated current of the fuse
