Contact Sales DCES – DC metering and monitoring solutions up to Megawatt charging The DCES series comprises advanced energy metering and monitoring solutions tailored for DC applications. These solutions cater to the specific requirements of energy billing in DC fast charging stations for electric vehicles, offering enhanced functionalities. 

Available in variants of 600A and 1500A, the solution provides cybersecurity, excellent measurement performances and robustness, and flexibility, including the ability to function as a standalone smart sensor. 

The DCES series completes our existing offer for DC meters for fast charging applications and destination charging: DCBM Series. The DCES 600 is meant for DC fast charging and destination charging, while the DCES 1500 is ideally suited for Megawatt Charging Systems targeting heavy-duty vehicles, particularly electric trucks (e-Trucks).

The solution provides cable loss compensation, 4-wire measurement, data authentication, and software update capabilities. It is also equipped with an RS485 interface and easy-to-integrate APIs, enabling straightforward integration into any communication system.
