Yoshino is the guy who pretty much invented the lithium-ion battery back in 1985, so he knows a thing or two about the technical and economic problems which must be overcome in order for electric cars

automated electric cars – the ones which will supposedly be used to game-change the car business by rendering obsolete the concept of individual ownership, to be replaced by transportation on demand. To be provided by fleets of automated electric cars.

For them, the technical and economic problems are even more serious than for the individually owned electric car – because they will be expected to operate almost continuously, without major downtime for recharging. Consider the implications of this.

Yoshino has. The industry ought to.

“A car shared by 10 people means it will be running 10 times more,” he explains.

“Durability will become very important.”

And durability is a problem when a battery pack is in near constant use, subjected to repeated daily discharge/recharge cycling – which would be necessary for the transportation as a service idea to work.

And to get power back into the battery takes time – perhaps the electric car’s biggest functional problem..
Fast charging works on a battery in much the same way that rapid pressurization/depressurization cycling works on the fuselage of an airplane: It fatigues the metal faster. Which shortens its useful life.
