Electric Vehicle Transportation Center
HNEI’s four-year EVTC program includes the following projects:
· Electric Vehicle Assessment and Energy Impacts to quantify net petroleum use by EVs on Oahu, dependent on charging strategies and renewable energy penetration levels, with a comparison to different alternative vehicle types and fuel mixes.
· Electric Vehicle Battery Durability and Reliability under Electric Utility Grid Operations to assess battery degradation under electric utility grid operations, and to identify conditions to extend battery performance and life.
· Economic Impacts of Electric Vehicle Adoption to estimate EV adoption rates in Hawaii, and the impact EV penetration levels will have on the economy in terms of gross state product, sector activity and household welfare.
· Effect of Electric Vehicles on Power System Expansion and Operation to investigate the construction and use of a relatively simple modeling tool that simulates day-to-day operation of Hawaii’s electricity grid systems, in order to make better use of renewables and reduce the need for new generation and transmission capacity.
· Electric Vehicle Interaction at the Electrical Circuit Level to determine potential solutions that EV charging brings to mitigate transient overvoltage (a power quality issue) at the sub circuit (neighborhood) level, in a service area with a high PV-to-load ratio.
