Planning and preparation for a Multi-Unit Install can be a daunting task. The installation of EV chargers in a Multi-Unit Dwelling can present developers a range of challenges, this article aims to highlight those challenges and discuss solutions to help navigate the evolving landscape of electric vehicle charging.
Challenges Facing Multi-Unit Installations
Government Legislation (Part S) effecting a Multi-Unit Install
One of the first things to consider is government legislation. The United Kingdom, in its stride towards a greener future, has implemented legislation (Part S) that came into effect on 15th June 2022. Amongst other things, Part S stipulates EV charging requirements in new developments, significant renovations, and buildings undergoing a change of use. While this ensures a baseline for EV infrastructure, it might not always align with the actual demand within a multi-unit dwelling. Conversely, the maximum number of chargers that can be installed without necessitating a significant upgrade to the existing power grid infrastructure poses another challenge. This limitation can hinder the scalability of EV charging solutions as the adoption of electric vehicles increases.
What is the minimum number of EV chargers required in a multi-unit dwelling?
For new buildings which are not residential or for renovated non dwellings, with more than 10 parking spaces:
- One of those parking spaces must have access to one electric vehicle charge point
- Additionally, charge cable routes for EV chargers must be installed in at least 20% of the remaining spaces
Multi-Unit Install – Power Requirements from the Grid
The installation of a single charge point requires consideration for its placement but multi-unit installs, as required by flats, apartments and multiple-unit dwellings, can require additional power infrastructure. The best way to navigate this issue is to liaise with your Distribution network operator who are responsible for distributing power from the national grid.
Solutions for an Efficient Multi-Unit Install
To tackle these challenges, a multifaceted approach is required, combining legislative compliance with practical solutions. Here are some key strategies:
- Multi-Point Charging Stations: Implementing multi-point charging stations is an efficient way to maximize the utility of limited space. These stations can serve multiple EVs simultaneously, reducing the need for extensive physical infrastructure.
- High-Speed Chargers: The installation of fast chargers offers a solution to the limited availability of charging points. These chargers can significantly reduce the time required for charging, thus serving more vehicles in a given time frame. This approach is particularly beneficial in multi-unit dwellings where charger access can be in high demand.
- Efficient Planning for Charger Locations: Strategic placement of chargers is crucial. Factors such as proximity to the power supply, ease of access, and potential for future expansion should be considered. Placing chargers in locations that are easily accessible to all residents can alleviate congestion and enhance user convenience.
- Scalability and Future-proofing: While adhering to the current legislative requirements, it’s important to plan for future needs. This includes installing infrastructure that can support additional chargers and considering the evolving technology in EV charging.
- Collaboration with Power Providers: To extend beyond the limitations imposed by the existing power grid, collaboration with utility providers is essential. This can lead to a more integrated approach in upgrading infrastructure to support a larger number of EV chargers.
The integration of EV charging stations in multi-unit dwellings is a step forward in supporting the UK’s environmental goals. Despite the challenges posed by legislative requirements and infrastructure limitations, effective solutions such as multi-point charging stations, high-speed chargers, and strategic planning can pave the way for a more EV-friendly future. By addressing these challenges head-on and embracing innovative solutions, multi-unit dwellings can effectively contribute to the widespread adoption of electric vehicles.
