It's going to be a bunch of shitty 48v hybrids. Car companies have already started rolling them out since Europe is requiring the same thing.

- tuatoru 4y ago48V is "very low voltage" and consequently very high current for a given power output. (Power is the product of voltage and current.) Loss (waste) of the energy that was stored in the batteries is proportional to the square of the current. Higher currents also require thicker wires so that the wires don't melt, making the vehicle heavier and more expensive. Non-shitty (bidet-cleaned?) EVs use higher voltages so they can have lower currents and therefore have less waste and light-weight wires. Currently around 480V, with 800V - 960V starting to be rolled out.
