Charging Infrastructure relates to the hardware and software that enables the supply of electricity to EV’s. This involves charging points, billing and access options and electrically supplied parking bays.
This is best suited for smaller battery sizes such as those in PHEVS (Petrol-hybrid electric vehicles) or when longer charging time is available. Plugs into a standard outlet 10km hour of range
Level 2 chargers allow you to charge your electric car in just a few hours. A level 2 charger safely delivers AC power via a dedicated AC EV charger 3.6-22 kW of power. 20-120km/hour of range
High-powered DC Fast-charge Station. 25-350 kW allowing you to charge your EV in a matter of minutes
Single Phase power is found in the majority of residential and commercial locations with the standard 2/3-ping plug sockets providing this power. Single Phase power can power an individuals dedicated charge point up to 7kW.
Three Phase power is more commonly found in commercial and industrial areas. Three-Phase consists of 3 alternating currents (AC) which allows for 22kW of AC charging power. Also, a pre-requisite for DC charging is a large availability of three-phase power.
For the average home-owner, Alternating current (AC) charging is how most EV owners charge their cars overnight. The Electric Vehicle (EV) possesses an on-board charger to power the battery, thus the speed of charging will also rely on the vehicles onboard charging speed capacity.
Common Maximum AC charging speeds are:
AC charging requires a lower amount of voltage to work, this being either Level 1 (120 Volts) or Level 2 (240 Volts).
Although a lower supply of volts means a lower charge speed, AC Charging has its benefits through its ability to be easily installed in most residential dwellings. It is an excellent solution for residential, multi-unit dwellings, workplaces and long-term parking locations such as hotels, train station and airport parking garages.
State of Charge (SOC)
SOC is the equivalent of a fuel gauge for the battery pack in an EV. SOC represents the amount of charge left in the battery through percentage values, similar to a phone.
Charging Management System (CMS)
The vehicles on-board charging management system controls the charging process and can decrease depending on battery percentage.
Battery Management System (BMS)
Every EV possesses a BMS to monitor the battery status.
EVSE – Electric Vehicle Supply Equipment
EVSE is an umbrella term relating to all technical components of a charging point or a charging station.
Battery Electric vehicle (BEV)
A Battery Electric Vehicle utilises electric motors and motor controllers to power the vehicle. The power is stored in the EV’s onboard battery which supplies the electricity to the vehicle’s wheels via an electric motor. A BEV must recharge at Electric Vehicle charging stations to replenish its battery.
PHEV (Plug-in Hybrid Electric Vehicle)
A PHEV is a hybrid vehicle possessing both an electric motor and battery and an internal combustion engine. The PHEV can be recharged by plugging into an EV charger or electrical outlet.
Plug-in hybrids possess 2 modes:
1. All Electric – motor &battery provide all of cars energy
2. Hybrid – Both electricity and gasoline are used
Hybrid Electric Vehicle (HEV)
A hybrid electric vehicle is a 100% fossil-fuelled hybrid car. These vehicles have a small on-board battery which is charged through regenerative braking, generating electric power in tandem with the combustion engine. Keep in mind all energy originates from petrol.
Plug-in Vehicle (PiV)
Is a blanket term relating to vehicles that come with a plug socket – BEVs & PHEVs.
Range Extended EV (Rex)
An EV with an electric drivetrain but a small petrol generator to charge the battery.
Type 1 Plug
Type 1 is a single phase plug which enables charging power up to 7.3kWh (32 A, 230V). Type 1 is slowly being phased out with the replacement of the Type 2 port.
Type 2 Plug
Type 2 plugs allow for up to three-phase power. In private settings, charging power up to 22kWh is commonplace, whilst power levels of 43kWh (AC, 63A, 400V) are able to be utilised at public charging stations.
The majority of public charging stations are built with Type 2 sockets, similar to modern EV’s (post 2018). All mode 3 charging cords are compatible with this socket type, with EV’s capable of being charger with both Type 1 and Type 2 plugs.
Type 2 is the Australian AC standard
Privately owned charging stations which are not available to the public, located in areas such as homes, multi-dwelling buildings, business premises and other private parking areas.
Charging infrastructure located in public areas (streets, highways), and are accessible to anyone.
This refers to charging offered in privately owned fleets and businesses.
Open Charge Point Protocol (OCPP)
OCPP refers to the communication between EV Charging Stations and central management systems.
Open Charge Point Interface (OCPI)
The OCPI is designed for exchanging information about charge points between CPO’s and eMSP’s, enabling scalable, automated EV roaming.
OCPI is an independent open roaming protocol and is free to use. It can work for direct connection or via roaming hubs.
ISO 15118 refers to an international standard outlining the digital communication procedure that an EV and charging station must use to recharge the EV’s high-voltage battery.
ISO 15118’s Plug & Charge
This is the process of inserting the charging plug into the EV charging, and then driving away when ready. Made possible because of a digital certificate located in the vehicle allowing it to communicate with the charging station via a Vehicle-to-grid (V2G) communication protocol.
This enables a seamless end-to-end charging experience, which includes the automatic authentication and billing of the user. This avoids the requirement of an RFID card, an app or to memorise pins.
Charge Point Management System (CPMS)
CPMS is an information technology platform created to manage and optimise the EV charging process. This technology is cloud-based, white-labelled and is maintained by the owner of the company.
