4. Storage batteries (Li ion, solid polymer electrolyte) that have small volumes and masses and high energy storage densities are in demand for both electric and hybrid vehicle applications. Estimate the smallest weight battery that could be used to provide full vehicle power for one hour of urban commuting in a family-sized five-passenger sedan. And, do some research to determine if the range (energy and mass) you calculated is realistic. Explain why or why not in 2-3 sentences. You can assume: The minimum power levels for such vehicles are 20 hp at average speeds, and the maximum power levels are 40 hp at peak acceleration. One hour of driving = 40 hp for 15 minutes + 20 hp for 45 minutes Li ion solid polymer electrolyte batteries have a specific energy density of 1400 kJ/kg
