Overview:

Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

What Are The Differences Between 400- And 800-Volt EVs? - Jalopnik (www.jalopnik.com)

One of an 800-volt system's greatest benefits is that it requires half the amperage of a 400-volt system to return the same charging speed, as multiplying voltage by amperage provides the charging speed. Higher charging rates incur more losses, so by lowering the current and raising the voltage, the whole process becomes more energy efficient.

Another win for the 800-volt system is that, due to the lower amperage current within the EV, thinner cables can be used.
