Energy Density
3.2.2.1 Energy density. The energy density is defined as the amount of electrical energy available per unit of either mass or volume. It thus deviates from the energy density of a pure fuel, due to the volume and weight of storage system components, and losses in the conversion process. Therefore, the energy density depends on the fuel ...
