AeroVironment and Recargo, developer of PlugShare, the electric vehicle (EV) charging station locator, have introduced a mobile app-based payment option for EV drivers charging on the West Coast Electric Highway fast-charging network in Oregon and Washington, the companies announced.

EV drivers can now access and pay for AeroVironment’s DC fast chargers and Level 2 charging stations through Recargo’s PlugShare mobile app on a pay-per-charge basis. There is no additional cost for this service.

Drivers still have the option to call AeroVironment’s customer service center to pay for and activate the stations. Pay per use charge rates are $4.00 for charging on Level 2 stations and $7.50 for DC fast chargers.

Customers can still sign up for a subscription program that provides EV drivers with unlimited charging along the West Coast Electric Highway for a flat rate of $19.99 per month, according to AeroVironment. The AeroVironment EV Net subscription service includes 24/7 customer support and online services that allow drivers to manage their account and track charger usage and energy consumption.

AeroVironment’s network in Oregon and Washington includes 55 DC fast chargers and 59 Level 2 charging stations forming the West Coast Electric Highway.
