Do Electric Cars have a 'standard' operating voltage?? Or does it
vary from one manufacturer to another??

Ah!! Good to read there is consistency ...... *NOT* !! ;-P

Â*More volts requires more cells. Better to standardise on the size of a
cell, set a maximum operating current and alter the number of cells
according to cost/power requirements.


Better still, standardised voltage and standardised packs where a small
town car may use one, while a larger, longer range car may use two or
three. Make the packs so they can be slid in or out - it doesn't matter
if each car puts them in at different locations, in different directions
or around different obstructions - and "battery stations" could use
robot arms, pre-programmed for all different models, to swap out
discharged batteries for fully charged ones. The service paid for at a
fixed sum, plus a rate for the increase in charge level.

That makes recharging an electric vehicle as fast as a petrol or diesel
one from the driver's point of view and ensures that failing batteries
are removed from circulation, with the cost spread amongst all drivers
rather than an individual being hit by a high fee.

It would also mean that as battery technology improved, all cars would
benefit, not just the latest model.
