Comemso Easy Chester Basic Package
The Easy Chester Basic is used exclusively for function testing of Electric Vehicle Charging Stations (EVCS) with up to 400V charging systems.
The Easy Chester Basic offers the Field Service/Maintenance Technician the ability to safely test the function, communication and safety aspects of the commercial DC fast charging stations with CCS type 2 connection
It offers an independent test and service function to cover DC fast chargers used at commercial EV fuelling stations, convenience stores, public carparks or service areas. Along with a test & service function for companies with large EV fleets. The Easy Chester fully simulates the communication of an electric Vehicle with the charging station against the relevant charging standards such as DIN 70121 & ISO 15118.
The Easy Chester Basic is a fully functional charger station tester with EV simulation, DC source and load. With the Easy Chester you don’t need to connect a vehicle to the ‘Charging Station’ to test it! The test time is extremely short the Easy Chester will show within 90 seconds whether a charging station is working correctly, without the need for specific knowledge of the control standards for such chargers and their communication protocol requirements. The Easy Chester simulates a standardized test vehicle behaviour in line with manufacturing standards including all communication protocols as opposed to the individual behaviours of various vehicle types and brands. It then shows a pass/fail condition against the required standard live on its touch screen display and then saves this information to the Easy Chesters memory. This can then be downloaded at a later stage via software to quickly produce meaningful PDF test reports.
Key Standards Include.
DIN 70121 is a German technical specification that defines the digital communication between electric vehicles (EVs) and DC charging stations for DC charging. It primarily focuses on the initial connection and authentication process in the Combined Charging System (CCS). Specifically, it outlines the communication protocol and application requirements for DC charging between EVs and charging stations.
ISO 15118 is an international standard for communication between electric vehicles (EVs) and charging stations, enabling secure and efficient charging and bidirectional energy transfer. It facilitates smart charging, which optimizes energy delivery based on grid conditions, and Plug and Charge, a feature that automates authentication and charging initiation
