More chargers, more users, more buildings—yet the grid capacity remains very much restricted. While EV infrastructure is growing, smart charging becomes a challenge when your sites grow. That’s where multi-level smart charging comes in. Instead of treating a site as one single point, the GreenFlux platform supports you in splitting power across different cables on your site, preventing local cable overloads before they happen. Let us explain how.
What is multi-level smart charging?
Smart charging ensures that the total power consumption from all EVs stays within your site’s available power capacity. It manages your grid constraint, optimises energy costs and integrates local renewables use.
Traditionally, setups relied on a single group of EV charge stations feeding from one distribution board or power cable. It worked well for installations with a handful of AC chargers and straightforward cabling.
But today’s sites? They’re bigger, split across multiple locations, sometimes mixing AC and DC chargers, and often sharing building power. One single 'flat' limit at the grid connection is not enough to protect various feeder cables and distribution points.
How does it work?
Multi-level smart charging introduces a ‘digital twin’ of your site’s physical electrical hierarchy:
- A primary intake with a limit for the entire site.
- Multiple distribution points with limits for specific cables or floors.
- Smart charging groups for AC and DC chargers.
- Real-time dynamic limits across all levels.
This layered architecture allows charging systems to manage capacity throughout the entire power chain rather than just at the main meter.
Whether a site has several boards, mixed charger types, or multiple buildings drawing from the same supply, multi-level smart charging ensures every part of the site works in harmony—even when drivers plug in unpredictably.
Some examples:
- A parking garage with six levels can assign each floor its own individual limit, all coordinated under one main limit.
- A hospital car park can give priority to fleet vehicles on one sub-level, while public chargers on another level adapt to leftover capacity.
Multi-level smart charging benefits for CPOs
A multi-level approach unlocks far more flexibility:
- Maximise existing infrastructure: squeeze every kWh out of your grid connection.
- Faster charging speeds: only reduce specific branches that are at their limit.
- No costly grid expansions: allow more chargers by balancing loads efficiently across the site.
- Future-proof flexibility: ensure your infrastructure is ready to adapt to the site's (future) physical layout.
All of this is being translated into the CPMS, where the aim is to give CPOs powerful configuration options without overwhelming them.
Let’s start the conversation
Multi-level smart charging is the perfect solution for today’s larger, more intricate EV sites. It ensures scalability, efficiency, and stability—making it easier for businesses to expand their charging infrastructure without running into grid or capacity issues.
