The trial forms part of the airport’s efforts to encourage the use of sustainable methods of transport.
It will run from August 1 until September 30, 2019, and the reduced rate will be brought in on a permanent basis if it is successful.
Rather than the Drop-off Zone, drivers of EVs will be able to use a dedicated section of LLA’s multi-storey car park for a reduced charge of £2 for a maximum of 30 minutes – a 75% reduction compared with the rate for other vehicles.
EV drivers will also be able to use charging points for free during this period.
LLA's chief commercial officer, Jonathan Pollard, said: “We’ve always encouraged people to travel to the airport in more sustainable ways such as taking the train and to leave their cars at home. That’s why we’re introducing this discount for electric vehicles.
"If there’s enough demand, we plan to make the incentive permanent and address any requirement to increase the number of electric charging points.”
