Our power would be far less than an EV - but the same principles still apply (as they do to laptops as well...)

Yeah a good rule of thumb for EVs is that they leave about 5-10% at the top and bottom. Some are more conservative than others (I believe the Volt leaves the most at the top and bottom--probably why so many Volt owners report the battery holding up well after many years).
My old Focus Electric also left quite a bit in the battery (of the 23kWh battery, only about 18kWh was usable).
