Riversimple Rasa (H2 FCEV micro mobility) weight investigation revisited
Revisiting my FCEV weight investigation My previous FCEV weight investigation for the micro-mobility, forever-in-development Riversimple RASA was first published in Jan 2018. After 3 years I thought it might be interesting to see what's changed and what has stayed the same. Summary of 2018 findings: The Rasa had a powertrain weight (not including motors or inverters which would also be on a BEV, or perhaps we can call it 'energy-train'?) of 151kg with 25.5kwh of usable H2 power and 0.5kwh of supercapacitor capacity giving a total energy capacity of around 26kwh or about 172wh/kg energy density. The Tesla model 3 at the time had a usable energy density of 156 wh/kg from its battery pack about 10% heavier than the H2 of the Rasa or about 2% of the total vehicle weight. Latest H2 figures. I couldn't find any updated documents for the specifications so I'll assume the general specs are unchanged, but I'll try to find updated component specifications. The Ras...
