>Information request from Tesla Motors

>
Compared to my previous analysis on the topic, Tesla Motors’ current vehicle offering has almost unfathomable capabilities. A 220 mile range, 180 watt hours per mile, and a full charge in 3.5 hours means that the battery has to store upwards of 39 kWh ($4.00 worth of electricity), but it has to transfer that energy at 11 kW. As I have previously analyzed, that should require a significantly more powerful electrical connection than the typical wall socket we plug most devices into.

I have put in an information request with Tesla Motors to ask what special equipment is used to charge the vehicle, and what electrical system upgrades they recommend for a homeowner that wants to get the 3.5 hour charge performance listed on their website.

If I hear from them, I’ll be sure to write up their answer. Update — It looks like someone from Tesla Motors may have left the answer in an anonymous comment.

    >Tesla Motors recommends you dedicate a 70Amp circuit for the high powered connector which is supplied FOC with every vehicle. It is specified at the bottom of the page on their website.However, the charge station is adjustable depending on your home’s available cicuit.http://www.teslamotors.com/efficiency/charging_and_batteries.php

    >Thanks! I’m not sure if our anonymous poster was from Tesla, or an astute reader. I’ll assume 70 amp, 220 V service, which is almost certainly the most powerful electrical connection in your house.
