When some EV customers selecting the fuse, we find that they are using normal high speed fuse instead of EV fuse. This is abnormal. 

Here is a brief difference between EV fuse and high speed fuse. for your reference if there is confusion.

1, Approval standard

2, Fuse type

3, Breaking capacity

4, Mechanical testing

5, Electrical testing

6, Thermal Testing

7, Chemical Testing

8， Safety testing

What's More: 

9, Fuse application different: EV fuse is mormal used in a moving surroundings, high speed fuse is used in stable, fixed environment;

10, The design between EV fuse and high speed fuse is different, EV fuse need to design base on JASO and TS16949, High speed fuse  mainly design base on UL standard;

11, The Process:

Due to EV fuse is working in moving environment, The arc-quenching filler and the fixing process is totally different when normal high speed fuse;

Also, the curing time is at least 10~50% longer than high speed fuse, Normally in 1 week time;

12, Installation way

EV fuse, mostly are assemblied with screw to avoid poor contact;

High speed fuse, with multiple installation, no limitation.

More EV fuse, Pls find in: 500V dc EV fuse, 800VDC EV fuse, 1000V dc EV fuse.

Also where is fuse needed in EV, Bussmann with full range.
