    Hi Sean:

    They were all very early prototypes which was quite unusual for Toyota to allow a journalist to drive. Very unusual indeed!

    Missing was the std. STAR safety system that Toyota will employ before the production variants reach us and the usual fitment that Toyota is known for.

    The RAV4EV’s have a 0 to 60 time of ~ 9.3 sec. which is pretty darn quick for a small SUV, a AER of ~ 96 miles (36 kWh pack useable) and it handles better than the std. RAV4 due to the pack placement allowing a lower Cg. There was no extra instrumentation to mentions as it is still being finalized but I am sure it will arrive with a Prius like display including efficiencies, SoC, DTE plus the new AZURE telematics system with distance to nearest charging point, range of the car to furthest charging point before depletion stops you dead, remote and current charging profile to meet your needs, pre-conditioning of the interior…

    It had a terrible MAX regen action similar to the MiniE that we have all come to loathe. Toyota said they will probably dial that way down if not eliminate it altogether with a button/switch once in a final production form.

    Instead of a stick, it used buttons for D, R, L and P. Not a game changer but just different and it may or may not make it into the final production vehicle. And because this was a very early on production unit, it had the large Red Emergency Stop button on the driver’s side dash for that just in case moment. This button engaged the solenoids which then opened up the breakers from the pack to the inverter.

    And the most important thing of all provided at the Toyota Sustainability seminar was?

    While not even close to most important thing by comparison to the information the multitude of presenters provided, I arrived about 02:00 AM in the morning and Teresa Bacal of Mission Impossible (Toyota’s contracted event handlers) had made sure there was a cheese tray, beef jerky, an apple and banana for me to snack on when I arrived. It was a life-saver to put it bluntly.

    Sounds like the makings of an excellent vehicle to me!

    Too bad it didn't have any instrumentation that could give you an idea of miles per kW.

    I'm curious how the costs break out.

    If you have space/available amps on your home service panel, level 2 should cost about the same as wiring a central A/C unit. For a three hundred unit installation though, there'd probably need to be additional electrical infrastructure (maybe including dedicated transformers?).

    Hi Rich:

    The study was blind and they asked three local contractors for bids to wire (retrofit) an existing 3-story parking garage with a given number of chargers in an approximate 90% 240V and 10% Quick DC charger mix. All 3-bids came in within 10% of one another and the cost was 6X's what the DOE has continuously touted. This included core drilling for wiring from floor to floor but had no additional monies for a larger feeder and associated HW to the building itself.

    I don't know what code is for parking structures, but if surface mount conduit is acceptable the core drilling wouldn't account for much cost discrepancy--maybe 1 day's work for a rig at ~ $2,000/day. Even if you have to core drill each connection to comply with code I'd guesstimate coring costs at less than $250/connection. (for comparison $50 is the usual unit rate I pay for a simple drill rig concrete penetration in a street or parking lot; coring is more expensive, but makes a tidier hole.)

    The bids seem high, probably they put in a lot of cushion for dealing with an unfamiliar client and technology?

    Hi Rich:

    I only know the base job specs and detail that was provided. The study was completed to find out what the actual cost of installing all of those chargers vs. the DOE's cost estimates. The presenter did say a new building should be less expensive but there is not going to be much new construction for the foreseeable future.

    I do not know what the chargers themselves cost but I would assume a connected charger would cost no more than an extra $500 vs. a dumb charger?
