Electric Taxis in Tokyo

Posted September 08, 2009 9:23 AM by CarDomain

Anyone who's been to Tokyo is immediately struck by two things. First, the living spaces in Japan's capital make the Big Apple's cramped domiciles look like a suite at the Trump Tower, and second, the city is at the cutting edge of technology.

So while it's not surprising that the city will be a test bed for electric taxi cabs, I was struck by how simply the city's largest cab company and its partner, Better Place, are choosing to handle the problem of limited range.

Instead of pouring tons of money into the research and development of a long-range cell, the pair is aiming to make a battery which can be swapped out quickly at stations around the city, so that a fresh charge would take about as long as filling a conventional gas tank. Pretty cool idea, huh?

Quite an interesting concept. It would require a high degree of standardization. Questions I have are; 1. how far can you go on a single charge? 2. What if your battery is only partially charged. Do you pay for a full charge? 3. Is this a stand alone technology, or can it be done as a hybrid? Charging stations would have to be spaced close enough to ensure not running out of juice. Some sort of trickle charger would be desirable for overnight charging.

We are replacing one pollution by another. What about the pollution due to aged batteries? Cadmium and others to our earth or water?

Well, we can control aged batteries with the introduction of law and incentive but we can not control smoke so it is a step forward. Do you think?

GA. The autonomy of a car is already reasonably solved by the current technology with hybrid applications. The problem is still recycling, manufacturing, disposal of an enormous number of batteries using metals that are not easily disposable.

This problem is yet to be solved by developing less aggressive batteries compounds, regenerative fuel cells, and - if not a complete solution - batteries that have a real bigger autonomy, allowing the use of less units for a longer time. Add environment impact in the batteries manufacture chain...

This is as much a problem - or even worst - than smoke.
