    Quick question -- do EV chargers continue to consume/use electricity while plugged into the EV, after the EV has fully charged? I am trying to determine whether they use more electricity in this "dormant" (I don't know the correct term) state than a typical home appliance. I don't think I have seen that factored into discussions about how much it costs to charge a EV....

    Thanks in advance for your responses.

    The Tesla Roadster, under normal environmental conditions, consumes very little power when not charging. It loses less than 1% of the battery pack capacity a day. In Standard charge mode it will top up the car once a day. In Storage Mode it will allow the charge to slow deplete to a low level, then it will charge periodically to maintain that.

    Under more extreme conditions it will use some extra power; for example, if the garage temperature is well below freezing it will occasionally draw some power to keep the pack warm (unless in Storage Mode).
