I expect the automobile companies are unhappy with people
who modify the cars and add banks of batteries because these cars are
carefully engineered, high-tech gadgets. Adding batteries probably voids
the warranty. If there is a malfunction or is the main batteries wear out
quickly there could be disputes and lawsuits over who is at
fault.
Nevertheless, it is a good idea to extend the range of these cars with
onboard batteries. Electricity at $.16 per minute is rather expensive. I
think in most locations an electric car would be cheaper than hybrid
gasoline car.
