The automotive industry's tightening embrace of electric vehicle (EV) technology means batteries hold the key: more energy, smaller packages, and significantly lower cost. A complementary solution, plug-in hybrid electric vehicles (PHEVs), incorporates range-extender devices. ETV Motors is developing advanced electrical automotive powertrain technologies: (a) High-energy, high-voltage Lithium Ion battery; (b) Ultra-low emission, highly efficient, high-power-density on-board charger. The Li-ion cell provides 4.7V per cell (cf 3.2-3.7V state-of-art Li-ion systems), with specific energy of 250-400Wh/kg. The cell chemistry incorporates novel Nickel Manganese spinel cathode material with inherent safety advantages and low-cost materials. High voltage requires new materials and treatments. Lab cells delivering 200Wh/kg and 500 cycles of 100% DOD (Depth of Discharge) have been demonstrated. Prototype cells (end 2010) will deliver 250Wh/kg, 1,000 cycles. As range-extenders, microturbines offer substantial advantages over ICEs: lower emissions, lighter, smaller, lower maintenance requirements. ETVM's on-board charger is a novel microturbine engine-generator (µ-TEG) producing 45-60kW. With combustor design based on Rich-Quench-Lean (RQL) principles, the µ-TEG has ultra-low emissions; high engine efficiency and low fuel-consumption over a range of part-power loads (10-45 kW). The modular architecture suits a range of applications starting from 60 kW/60 kg/*20% and up to 45 kW/120 kg/*>36% (* thermal engine efficiency).
