What is the Problem we are solving?Fossil <strong>Energy</strong>Renewable<strong>Energy</strong>
Two main centers of Innovation• Electric <strong>Energy</strong> Storage (Batteries)– Battery lifetime– Battery safety, cooling, management– Battery cost reduction– <strong>Energy</strong> density and range improvement• Electric Power Conversion and Control (Power Electronics)– Chargers– Traction inverter (motor control)– Supercharging (off board high-power DC charger)– Renewable <strong>Energy</strong> Integration (grid-tie inverter/chargers)– Cost, efficiency, power density
