EVSE安装指南

EVSE InstallationGuideline February 2024 electricvehiclecouncil.com.au Interested in how to install EVSE?Here’s what you need to know. Disclaimer: The Electric Vehicle Council (EVC) is not your local electrical regulator.Therefore, this guidance should be considered in combination with input from yourrelevant electrical regulator or licensed electrical inspector and manufacturer’sinstructions.It is not to be interpreted as legal guidance. If in doubt, please contact therelevant electrical regulator in your region for clarification. Who can install an EV charger? In Australia a person who is not a licensed electrician is not allowed to install an EVcharger (also known as Mode 3 or Mode 4 Electric Vehicle Supply Equipment or EVSE),in the same way that they are not allowed to install a power point or other fixedelectrical equipment. A licensed electrician is permitted to install an EVSE. There is no additional specialrequirement for the electrician to satisfy in order to install EVSE, as distinct from solarinstallations where additional qualifications are needed. Consumers do not need to be licensed electricians to use the portable type of EVcharging cable that plugs into a standard power point. This is known as ‘Mode 2’charging, and the equipment is referred to as “In Cable Control and ProtectionDevice” or “IC-CPD” cables. Standards and Regulations Legislation in each state and territory relating to electrical safety calls up regulations,which refer to both Australian Standards (which have national coverage), and Serviceand Installation Rules (which have jurisdictional coverage in each state and territory). The key Australian Standard is AS/NZS3000:2018, which is known as the wiring rules.This standard has many mandatory requirements. Mandatory requirements relevantto EVSE installations include the selection and installation of circuit breakers andRCDs, cable sizing, and protection of installations against mechanical damage. AS/NZS3000:2018 also includes some informative sections, which are not mandated,but which should be followed unless there is good reason not to do so. Appendix P isone of these, providing “guidance for installation and location of electrical vehiclesocket-outlets and charging stations”. In some instances in this guideline, the EVC provides a viewpoint divergent fromAppendix P and explains why, but in general the EVC position is that Appendix P is auseful resource for the installers and should be followed. The service and installation rules vary by state and territory and are mandatory. Switched load sizing in service andinstallation rules In most jurisdictions, the SIRs set requirements around the maximum size single phaseswitched load that can be installed. The historical basis for these requirements is loadbalancing across phases, but more recently the interpretation of these clauses amongstthe DNSPs and regulators responsible for these documents has included a focus onsystem level load management. More detailed information around this is available here: https://electricvehiclecouncil.com.au/guidelines/ In Victoria, NSW, Tasmania and Western Australia, it is permissible to install a 32A singlephase EVSE (7.4kW). Victoria and NSW have elements in their SIRs that refer to loadbalancing but leaves the decision to the installer. Tasmania’s SIRs do not address thetopic of load balancing in their SIRs. In the ACT and Northern Territory, single phase EVSE installations are required to belimited to 25A (5.7kW). In South Australia and Queensland, single phase EVSE installations are required to belimited to 20A (4.6kW). South Australia has a process known as ‘smart apply’ which started incorporating EVSEinstallations in July 2022, whereby the installer can seek an exemption from the 20Alimitation, to install a 32A single phase EVSE. Queensland permits the installation of 32A single phase EVSE where the EVSE can becontrolled by the DNSP, but where the EVSE is installed on the ‘always available’general circuit, the limitation is to 20A (nameplate).3-phase 32A EVSE may be installedwithout control. The EVC position is that the various SIRs across the states and territories should beharmonized in this respect, enabling the installation of 32A single phase EVSEeverywhere in the country. It is not useful for us to have widely differing requirements ofthis nature in different jurisdictions. Dedicated circuits A dedicated circuit is specified in section P3 of AS/NZS3000:2018 for the connectingpoint of an EV. There are many cases where an EVSE can support more than oneconnecting point of an EV, particularly for mode 4 DC EVSE, so the EVC does not fullysupport this specification as written. The EVC position is that a dedicated circuitshould be provided to the EVSE. No other appliances or outlets should be wired fromthe circuit supplying the EVSE. RCDs Residual current devices (RCDs) provide safety against electric shocks – they’recommonly known to the public as safety switches. A
