EV Charging Station
Last Updated: Nov 12, 2021
An Electric Vehicle (EV) charging station supplies power for recharging electric vehicles. Typical
EV charging stations are made up of at least one smart controller board and one power socket
board. The smart controller manages security, services and connectivity to a remote server and
the power socket board distributes and measures energy.
EV charging stations require high levels of efficiency, accuracy, connectivity and security. NXP
solutions meet the requirements with accurate power measurement, device management and
data security. Our rich enablement supports faster time to market with less complexity and
reduced cost, and NXP's product longevity program supports longer product lifecycles.
