Electric Vehicle Tech Flashcards
(10 cards)
What does FCEV stand for?
Fuel Cell Electric Vehicle
Powered by hydrogen fuel and generates electricity on board.
What is an HEV?
Hybrid Electric Vehicle
Combines an internal combustion engine with an electric motor and charges via regenerative braking and the engine.
What distinguishes a PHEV from an HEV?
Plug-in Hybrid Electric Vehicle
Has a large battery that can be plugged in to charge and offers a short range in electric-only mode.
What is the focus of the Forward Approach in EV integration?
Optimizing energy source and vehicle before integrating into the power grid
Starts from the vehicle side.
What does the Backward Approach emphasize?
Focusing on the power grid and infrastructure then adapting vehicles to work with it
Starts from the grid side.
What is Vehicle to Grid (V2G)?
Electric vehicles can send power back to the grid during peak demand
Helps balance the grid and uses stored energy, requiring bi-directional charging.
What is Vehicle to Building (V2B)?
Electric vehicles supply power to buildings during peak demand
Acts as a backup battery.
What is bidirectional charging?
Allows EVs to send and receive power
Used in V2G and V2B, essential for grid support and energy storage.
What is smart charging?
Charges EVs when electricity is cheapest or grid demand is low
Uses software and communication devices to manage charge times and rates, reduces costs, and supports grid stability.
What is a Dual Active Bridge?
Two H bridges that convert DC to AC
AC transfers to a transformer, and AC is converted back to DC on the other side with phase shift controlling power flow.
