"The VW Milano Taxi Concept, with its top speed of 120 km/h is driven by an electric motor with a peak power of 85 kW (continuous power: 50 kW). The motor is supplied with energy via a lithium-ion battery integrated in the concept car's underbody. Thanks to the implemented battery storage capacity of 45 Kilowatt-hours (kWh) and the relatively low vehicle weight (1,500 kilograms), despite the battery, it is possible to cover distances of up to 300 kilometres (per NEDC) depending on driving style. The storage battery can readily be recharged to up to 80 percent of its total capacity in just over one hour, the exact time depending on the available recharging infrastructure and battery's momentary charge state."
So after every 4 hours of use or so the car will need to be charged for over an hour? Sounds like that will be effective.
Then again, if Italian taxi drivers are as industrious as the rest of the country has a reputation for... maybe this will work fine.
I share your concerns about the decreased productivity due to the need to charge them too often for long periods. Taxis are up and down on the road most of the day, some even 24h/day as some companies use several drivers for each car.
Having to stand the car down every few hours for at least an hour to recharge, plus having to drive to and from the recharge station rather than the closest gas station, will no doubt put many cab companies and owners off, even if the fuel saving is significant.
That said, electric cabs would do a lot of good to cities in terms of reducing pollution.
Looks like I picked the wrong week to quit posting...

What they need to develop is a standard size battery that can be swapped over to charge outside the vehicle, whilst a 2nd battery is running the car. Or a "filling station" where you swap your dead battery instantly for a fully charged one...
