- Key Application Requirements • HEV (40kW battery full hybrid system example) – High specific power: >2,000W/kg (<20kg battery) – -30C cranking capability: 5kW – Extremely high shallow cycle life: 500k cycles – Long operating life: 15 years – High power/energy ratio: >20:1 – Cost: goal of $20/kW ($800) @ 100k/year • PHEV (Ford Escape Plug-in Hybrid battery system example) – Higher energy power battery: 10kWh / 25mi / 140kg / 5800 in3 – Requires full power over a wide temperature range – Both high deep (5,000) and shallow (500k) cycle life required – Must be fully abuse tolerant when packaged in the crash zone – Power/energy ratio: 5:1 to 15:1 – Cost: $1,000/kWh ($10-15k); goal = $200-300/kWh @100k/year • EV (30kWh electric vehicle battery system example) – High energy density: >120Wh/kg (30kWh / 100mi / 250kg battery) – High deep discharge cycle life: 3,000 cycles to 80-90% DOD – Power/energy ratio: 2:1 to 3:1 – Cost: $600/kWh ($18k) at volume; future high volume prospect = $300/kWh
