    These will never be higher than 600VAC/850VDC in the US, due largely to protection requirements.

    6 minutes is about 5x faster than the Primes regeneration is capable at peak with no fast charging designed in. The smaller the cell capacity the fast it is to charge. A pack with many small cell/charger pairs recharged in parallel could get close to this charge time using current cell design. The on board bus bar would be the critical component as we already have seen problems with oxidation of the connection terminals in the previous battery packs. Maybe the only problem with these packs and not the cells but could cause damage to the cells if not fixed.

    Fast charge and discharge is what NiCad's were good at. To bad we have wasted this technology with hysteria

    With high voltage and current are we going to need a member of the Brotherhood to fill up our cars? Except in NJ where they got this covered by unions already?

    Ok not a substation in your car but to be viable an electric "gas station" or group of will need something like that. I can see the smoke rise from the two coal stations to my north from this former gas station where I sit but know that the miles of big copper grid needed to make this an EV station will never happen. Above 80% grid capacity now.

    Lots of companies boast only Toyota does. Hybrids, Hydrogen, ect

    Comments to an article on this pointed out that these aren't new batteries. Toshiba has had them for about 6 years now. They might even be going into iMiEVs at moment. The latest press release likely has to do with the fact that DC chargers capable of charging the pack at this rate appear to actually be coming out soon. Superchargers are at 120kW, CCS can go up to 200kW(perhaps also CHAdeMO), and VW has 350kW ones.

    While this battery can take multiple fast charge events without degradation, it is low energy density. The iMiEV is a sub 70 mile BEV. To get the same range in a BEV has now using different chemistry with these batteries means you would need a bigger pack physically. So even less trunk space.

    These batteries are better suited for short range city cars where chargers can be conveniently located, and the car owner may not have home charging. Smaller pack size mean less space lost to the battery, and cooling is easier.
