Scope:

The project will focus on DCFC with 20kW to 350kW of rated power output. The draft standard will
include test methods to determine efficiency at representative temperatures (e.g. -30C, -7C, 20C and
40C) and different loading conditions (e.g., 25%, 50%, 75%, 100% load). It will include weighting factors
representing typical climate conditions in Canada (-30°C to 40°C) and criteria for reporting of weighted
system efficiency. It will establish minimum efficiency criteria and levels for DCFC in Canada. Testing
shall include measurement and reporting of total harmonic distortion (THD), power factor, and reactive
power in the various operating modes indicated above. 

The C810 draft standard will include an informative annex including guidelines for sizing, selection 
and control of auxiliary/ancillary equipment for supply voltage transformation; improved power factor
mitigation of harmful harmonics; and provisions for heating and cooling loads, to optimize system 
energy use during standby and partial on mode operation of EVSE DCFC equipment. 

Project need:

To develop a test procedure to measure the energy electric vehicle supply equipment (EVSE). This proposed New Standard is being developed at the request of C402 technical committee on industrial energy efficiency and energy efficiency funders. It will provide the industry with an acceptable test procedure to measure the energy efficiency of their DC fast chargers.
