As an electrical engineer, I
As an electrical engineer, I can attest that this article is completely incorrect.
The author confuses very basic concepts such as battery voltage and battery power. The battery voltage has nothing to do with battery power.
Power is not measured in Volts. It is measured in Watts or Kilowatts.
Boosting battery voltage to 650 volts doesn't increase battery power. And I'm sorry but the boost converter does not (quoting the author here) "instantly gives you more power on demand".
Using authors incorrect logic we can replace Prius battery with a flashlight AA battery. Just add a boost converter that will increase battery voltage to 1000V and Voila! We get a formula one Prius! After all, per the author's logic, higher voltage means more power.
When someone gets zapped by static electricity the voltage gets up to 20,000 volts. Following the author's train of thought, it means even more power, and the next generation of hybrids can be powered by static electricity. Just rub a plastic ball with a wool sock and get an instant power boost of 20,000 volts before climbing this hill!
The author claims that he is an automotive consultant and a technology instructor who teaches students. I feel bad for the author's clients and his students.
