High-voltage EV battery packs: benefits and challenges. More voltage, more better?
In 2020, Porsche delivered just over 20,000 units of its luxury Taycan EV—the first vehicle from a major automaker to sport an 800 V (nominal) battery, which is more than double the voltage of its competitors (and firmly into light-rail and switchyard locomotive territory, actually). It appears that many other EVs will soon follow in... Read …

How to select EV Fuses
So, we can say that the total clearing time is the sum of melting and arcing durations. We use the breaking energy calculation to check if the neighboring components can withstand until the fuse breaks the current. For instance, if the I 2 Rt energy limit of a contactor is less than the selected fuse, we should change the selected contactor.
