There are two schools of thought out there and over time one school of thought might win out and the other will pass away. It’s difficult to tell at the moment which one will prevail but I have my suspicions.
There are many EVs with small battery packs which rely heavily on DC fast charging to take them on longer trips. The benefits of this school of thought are that you do NOT have to lug around extra battery weight and capacity that you will only use once in a while. This keeps the cars initial purchase price low and in many cases can easily satisfy the USAs average distances of 40 miles. This does however, limit you on your year’s vacation trip that is 400 miles from your home. This group of EV pioneers has managed to complete some crazy stories of nightmare DC fast charging ordeals and very long trips indeed because of malfunctions, freak weather patterns and overall neglect.
The Electric cars in this camp are the Mitsubishi iMiev, the Smart EV, the Ford Focus EV and the Nissan Leaf EV.
The second EV big battery school of thought is currently sitting with Tesla. Tesla has the most of any current EV offering and yet also has the highest price tag. It does however, also boast of the lowest cost per watt of energy storage. This makes the 260 miles range Model S has into an EV camel. It can easily travel great distances because of the marrying of Tesla’s Fast Charging network but if these Tesla owners only travel short distances they wouldn’t need the extra battery capacity. I realize there are many other reasons for wanting to own a Tesla but that isn’t what I’m talking about here.
If the average US person drives only 40 miles a day or less, then a double that range battery would satisfy a great deal of the populations needs however that 400 mile vacation would be much more doable in the Tesla S but the rest of the year it is just carrying around extra battery capacity for no reason. You see my point.
As the EVSE (Electric Vehicle Supply Equipment) continues its roll out into America, small battery packs will be much more easily accommodative of small EV battery packs. Once the DC fast charging infrastructure is rolled out, the less difficult it will be to take the small EV battery pack cars on longer trips.
