Yes, it is less efficient, under most conditions, to use the battery. There are energy losses (mostly as heat) when the energy is convertered from one mode to another for storage, then more loss when convertered back from the battery. Remember that the inverter gets hot enough to require it's own radiator/cooling system. Heat is energy.MiracleMax said:What confuses me about why Pulse and Glide is so efficent is, why is using the battery a bad thing? Is it less efficient to charge the battery with the ICE, then drive the power train with the EM, than it is to drive the power train directly with the ICE?
Does this mean that driving at low speeds using just the EM and not the ICE is also a bad thing?
TIA for info.
