EV Charging: Finding the Right Balance Between Power and Availability

In the world of electric vehicles (EVs), the debate often centres around the belief that bigger and more powerful charging stations are better. The idea is that faster charging times benefit both drivers and landlords. However, the reality is more nuanced, and finding the right balance between power and availability is crucial. In this guide, we’ll explore the factors that determine efficient EV charging and how to meet the diverse needs of EV drivers.

  • Charging Speed vs. Availability:
    • The prevailing belief emphasises the importance of faster charging, but customer feedback suggests that charger availability is just as, if not more critical to being able to effectively charge your vehicle on a journey.
    • While 300kW chargepoints are considered the fastest, their practicality is limited, especially for the majority of EVs on the road – you will need to check your own model manual to ensure that your vehicle can actually charge at this rapid rate.
  • Not All EVs Are Equal:
    • Charging rates vary among different EV models, and understanding these differences is key to optimizing charging infrastructure.

  • Power Considerations:
    • Electricity is abundant, but the grid infrastructure’s limitations must be considered when choosing charging options and every site is different.
    • Installing high-power chargers may require significant investment in new substations and the groundwork to complete these, impacting the overall cost.
  • Supplying the Many:
    • A hypothetical scenario illustrates the trade-offs between installing fewer high-power chargers and more moderate-power chargers to accommodate a broader range of EVs.
    • The benefits of having 8 to 12 – 47kW-100kW chargers satisfying more drivers more of the time is better than having one or two single 300kW chargers due to the fact more people can charge at the same time with the 47kW charger also providing 80% charge in around 30mins with multiple people being able to use the units is a potentially more cost effective solution.
  • Dwell Time Matters:
    • Different charging needs exist for en-route and destination locations, with the emphasis on selecting charge rates based on the expected dwell time.
    • A dynamic power distribution approach ensures a compromise between high-powered charging and higher numbers of chargepoints.
  • Dynamic Load-Balancing Technology:
    • Exploring dynamic load-balancing technology as a solution to intelligently allocate available power across multiple charging units, maximizing installation while still allowing high-powered charging.

Our Approach at ElectRoad:

ElectRoad prioritises installing sites with the right number of units at the optimal charge rate to maximise the potential revenue generated from every site.

The ElectRoad network embraces dynamic load-balancing technology, offering a range of charge rates to cater to different dwell times and EV models.
