Solutions for EV Charging Stations and DC Voltage Monitoring
CARLO GAVAZZI offers EV Charging Meters for monitoring either the AC side or DC side of DC charging stations. This allows the user to be billed for only the actual energy being used.
Our DC EV Charging meters are available for up to 1000 VDC and up to 600 ADC and can be mounted to both busbar and cable lugs and require no exernal current sensors.
Our AC EV Charging meters are available for use with standard current transformers. Furthermore, we offer inline types that measure a line current up to 65 A directly thereby eliminating the cost of current transformers.
With the current surge in electric cars and light rail transit, monitoring of DC Voltage systems is becoming increasingly important to ensure the reliability of the service. CARLO GAVAZZI has DC voltage metering devices and transducers for DC bus monitoring of the voltage, current, power and energy and provide an interface to your managment system.
In addition, we can provide our UWP Monitoring Controller which can monitor a network of meters for logging, viewing, and uploading of data to cloud based data storage systems. Additionally, it provides alarming functions on power anomolies by sending out alarm text or emails to maintenance personel.
