Needs analysis for EV charging infrastructure

Our team will conduct a needs analysis to discuss your business needs and goals. These may include monetisation, system integration, capacity requirements, accessibility needs and more. We will also help you identify your user types and assess their needs too, so that these can be incorporated into the design. Your users may include daily commuters or long-distance travellers, fleet vehicles, or staff charging their own vehicles. 

With basic forecasting, we can determine the number of vehicles you expect to charge daily (including the timing and frequency) and incorporate this information into the design.

Site assessment for EV charging infrastructure

Our team will undertake a comprehensive site inspection to gain an understanding of the proposed site as it currently exists and its capacity to incorporate EV charging infrastructure. This includes consideration to: 

  • The capacity of the local grid (or renewable energy source) to support the new infrastructure
  • Current uses of the site and traffic flow 
  • Space available for accessibility and placement of the new infrastructure
  • Potential obstructions, safety issues and hazards

This is valuable information for determining the best location for your EV charging infrastructure, so we can adequately plan and design your charging station with the correct layout and electrical infrastructure needed to support it. 

Customised design for EV charging infrastructure

A commercial EV charging station includes multiple infrastructural elements to be incorporated into the design.

EV charging units

Based on your requirements (including charge power and user capacity), our team will determine the best EV charger model, features and setup for your EV charging station. 

  • Number of chargers: Depending on usage predictions and available space (as determined by the site inspection).
  • Type of charger (charge power and speed): Level 2 EV chargers can fully charge most EVs in 4-6 hours (most common in commercial settings). DC fast chargers can charge an EV in under an hour (good for roadhouses where users require a quick/rapid charge). 
  • Charging cable length and capacity: Your cable capacity will support the electrical current required for the charging power needed (important for safety). It will also be the appropriate length (this is dependent on how close the EV is able to park to the charger). Longer cables can be quite heavy to handle. 
  • Payment and authentication systems: A carefully selected make/model with the payment and authentication features that your business needs such as card readers (for instant credit/debit card payments), RFID readers (for member-based systems or fleet cards), and mobile payment integration (in-app payments). 
  • User features: To optimise the user experience including status indicators, LEDs or screens indicating charging status, faults, or availability.
  • Backend system integration: Management software (dependent on your business needs) for centralised control and monitoring of multiple chargers, analytics, and reporting.

Solstra partners only with trusted, quality brands and manufacturers that prioritise high-level customer support.

Site layout

Implementing the right infrastructural elements into a safe and easily accessible layout ensures a user-friendly experience and repeat visitation.

  • Adequate space: Your charging station will allow adequate space for multiple EV’s to charge simultaneously at a safe proximity to the charging station and adequate space around the charger/s themselves. The car parks are marked, designated spots – wider and longer than standard parking spots.
  • Traffic flow: Vehicles will be able to easily enter, park, charge and exit without disturbance to others already charging and without causing traffic congestion.  
  • Surrounding environment: The charging station will be free from hazards and obstructions such as hard knocks, falling objects and debris.
  • Landscaping (outdoor charging stations): Trees, plants, and other decorative features to enhance aesthetics and user experience.
  • Accessibility: The design will include accessibility for disabled users. 

Your EV charging infrastructure will be designed with scalability in mind for possible future upgrades or expansion.

Electrical Infrastructure

Solstra will assess the capacity of your existing electrical infrastructure and plan the necessary upgrades to ensure it can handle the additional load. 3-phase power is ideal for commercial EV charging stations, if it is available at the premises.

  • Electrical load: Upgrades for your switchboard (power distribution), transformers (power conversion to the appropriate voltage) or other key components where necessary. 
  • Protection: Adequate earthing systems and circuit breakers (RCDs) for personal safety and protection against infrastructure damage and electrical faults.
  • Grid integration: The chargers will be connected correctly to the local electrical grid, in liaison with your utility provider.
  • Data connectivity: Sufficient data connections to connect and network “Smart” EV chargers to support operation, billing, and monitoring features. These connections can be wired (ethernet) or wireless (wifi, cellular) and also allow the units to receive firmware updates. 

Solstra also specialises in commercial solar! If you have an existing solar system installed at your business, Solstra can incorporate the necessary upgrades so that your new EV charging infrastructure can run on clean, renewable energy to offset your electricity costs and reduce your carbon footprint.

Safety, security and protection

Most commercial charging stations are in a location accessible by the general public, meaning that safety and security features are necessary to protect both the user, and your investment. Solstra will incorporate the recommended features into your design based on your business needs, and the location.  

  • Signage: Clear and appropriately positioned signage to direct vehicles and provide user instructions (including operation, precautions and payment) 
  • Cameras: CCTV placement for monitoring and supervision of the charging station itself and the surrounding area.
  • Lighting: Adequate lighting for ease of operation and user safety at night or in poorly lit areas.
  • Bollards: Protection for your EV charging infrastructure from accidental vehicle damage (yes it can happen!)
  • Shelter: A roof or shade to protect the user from the elements including rain, snow and direct sunlight.
  • Weather protection: If your charging station is outdoors, we’ll ensure the charging units have an adequate weatherproof rating for the local weather conditions including waterproofing and temperature resistance.

Frequently asked questions (FAQs)

What types of EV chargers are there?

EV chargers can be installed with AC (alternating current) or DC (direct current) power. The power levels are identifiable as Level 1, Level 2 and Level 3. Level 1 and Level 2 EV chargers use AC power (Level 2 delivers more power, requiring a 240-volt input). Level 2 and Level 3 chargers are commonly installed at public charging stations, with Level 3 charging uses DC power at high currents (fast charging). 

What Australian Standards and regulations apply to EV charger installation?

An EV charger is a hard-wired appliance and by law, EV charging infrastructure must be installed by a fully qualified, licensed electrician (Registered Electrical Contractor). Licenced electricians in Australia are required to comply with the Australian Standard AS/NZS 3000 Electrical Installations (Australian/New Zealand Wiring Rules) and the Electricity Safety Act 1998. This ensures the safety, compliance and integrity of your installation.

The following Australian Standards and regulations apply for commercial EV charger installations:

  • All electrical equipment imported and sold in Australia: AS/NZS 3820
  • EV charger cable sizing: Australian Standard AS/NZS 3008.1.1:2017
  • Where an EV charging station is integrated with solar battery storage: AS/NZS 5139 Electrical Installations – Safety of Battery Systems for use in Inverter Energy Systems

The Australian/New Zealand Wiring Rules are maintained by Standards Australia and are available for purchase.
