Preface  

This is the first edition of CSA C810, Energy efficiency and test methodology for EVSE DCFCs.   This Standard is harmonized to the extent possible, with the EPA ENERGY STAR® Program Requirements for Electric Vehicle Supply Equipment: Final Test Method for DC-output EVSE Rev. March – 2021, and ENERGY STAR® Program Requirements for Electric Vehicle Supply Equipment Eligibility Criteria Version 1.1.  CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of EfficencyOne, Electricity Canada, FortisBC Inc. (Electric), Hydro-Québec, Independent Electricity System Operator, Natural Resources Canada, Nova Scotia Department of Natural Resources, and Renewables, and Québec Ministre de l’Énergie et des Ressources naturelles (MERN).  This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.  This Standard was prepared by the Subcommittee on Performance of Electric Vehicle DC Fast Battery Chargers, under the jurisdiction of the Technical Committee on Industrial Equipment and Strategic Steering Committee on Performance, Energy Efficiency and Renewables, and has been formally approved by the Technical Committee.  This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. 

Scope  

1.1 General  

This Standard specifies a test method for calculating the energy efficiency of electric vehicle supply equipment (EVSE) for direct current fast charging (DCFC) across a full range of load conditions. It defines operating modes, and provides energy efficiency minimum requirements for these operating modes.  Note: Many owners and operators of DCFC are concerned with the amount of non-dispensable energy these chargers consume in no vehicle mode, especially in the winter when auxiliary heaters are often used. It is recognized that no vehicle mode power during cold temperature has not been a major consideration for charger efficiency because, to date, energy efficiency testing has been typically performed only at room temperature and full-rated load. This Standard seeks to provide an understanding of a given DCFC’s energy efficiency.  

1.2 Included in this Standard  

This Standard applies to AC three-phase and single-phase powered EVSE for DCFC between 20 kW to 350 kW of rated power output to a vehicle connector.  Note: The typical configurations are  a) discrete unit — where the power conversion, user interface, communication, and control are all integrated into a single unit. These are intended to be tested as a standalone unit;  b) central cabinet and dispenser(s) — these are intended to be tested as a combination of one cabinet and at least one dispenser, including if one dispenser is incorporated as part of the cabinet; and c) hybrid — these can behave as a discrete unit on AC power and also connected to an external DC power source. These configurations should be tested twice — once as discrete unit and once at peak capacity (with the addition of DC supply) as central cabinet and dispenser.  

1.3 Excluded from this Standard  

This Standard excludes wireless power transfer devices, pantograph style devices, and DC-powered devices.  

1.4 Terminology  

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option that is permissible within the limits of the standard.  Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.  Notes to tables and figures are considered part of the table or and may be written as requirements.  Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
