Quinn Load Management – managing your charging station’s energy

Dynamic load management is a key part of our charging infrastructure. Think of Quinn Load Management as a conductor that orchestrates the distribution of energy: making sure that multiple cars can be charged quickly and efficiently while protecting fuses from overloading. Quinn intelligently distributes the available energy for charging, and as it is compatible with a broad range of different charging station models, it enables you to get the most out of your building’s charging infrastructure.

As EVs become mainstream, larger buildings and areas with several parking spaces need to be prepared with scalable electric vehicle charging infrastructure.

Alpiq has developed a cutting-edge solution for buildings to serve the electric car mass market. Quinn is the most comprehensive dynamic load management system on the market, holistically monitoring the overall energy consumption.

Quinn works independently from manufacturers and offers compatibility with a broad range of charging station models. This means you can scale your charging infrastructure sustainably, while software updates provided over the internet make new functionality available on a regular basis.

Optimal load for electric cars

Dynamic load management is an integral part of an efficient charging station operation. Since the system is connected to Alpiq’s energy platform, it collects data from other energy appliances and calculates the building’s current energy capacity in real-time.

Based on the building’s overall energy capacity and current consumption, Quinn dynamically provides an optimal load for charging cars. Dynamic load management enables multiple car charging stations to be used at the same time with the highest possible power without jeopardising the electrical infrastructure.

Whereas static load management systems set a certain fixed threshold for charging, such as 50 kW, dynamic load management provides the total available energy for charging. This makes charging up to 200% faster.

This page walks you through how dynamic load management fits into your overall e-mobility infrastructure strategy and the benefits it brings to your facility.

Basic infrastructure: the first step to scaling charging infrastructure

Today, many buildings lack sufficient electrical infrastructure for charging multiple electric vehicles. The few existing charging stations receive energy from the main distribution board, and they are connected to the main electricity meter. This might work fine for up to three chargers, but any additional charger would increase the load to the extent that it would exceed the building's would exceed fuse limit, resulting in a blackout.

Alpiq supports property owners and facility managers to install basic infrastructure in the parking garage. A flat cabling system is installed on the ceiling or wall to supply the parking spaces. All installed chargers will be plugged into the cabling system, which is connected to a separate meter dedicated to e-mobility. This setup is the foundation on which you can build scalable EV charging infrastructure.

Load management: static vs dynamic

Many hardware suppliers provide proprietary static load management systems. However, the more electric cars you have in the garage, the more problematic static load management becomes.

Problem 1: Static load management slows down the charging speed

Static load management is, as the name suggests, a fixed way of allocating the energy for charging. As the maximum capacity is set in stone, the charging speed of each electric vehicle slows down with every additional car - even though there may be more energy available.

Quinn load management, however, adapts to the real-time situation and enables cars to be charged at a higher power, if available, making charging sessions up to 200% shorter.

Problem 2: Static load management is not a synchronised solution

Hardware manufacturers provide static load management as part of the hardware package. It does protect the fuses, but it doesn’t support your charging infrastructure in the long run - especially in multi-family properties.

The problem with static load management is that it only supports chargers within the same hardware family. But, more often than not, your building will have several different chargers. This results in two redundant systems and an even slower charging speed.

Problem 3: Static load management is neither flexible nor future-proof

You, as a building owner or facility manager, need to make sure your e-mobility strategy is built for the long term.

When you add chargers to your garage, you need to think what the charging portfolio will look like in the future. As the electric car industry is still in its infancy, new innovative products keep appearing. Therefore you need to be flexible and have the ability to add different chargers to the garage later.

With static load management, you are stuck with a single hardware provider, whereas Quinn is a hardware-agnostic solution, giving you the flexibility to use multiple different chargers. Quinn is compatible with the most widely used chargers, and Alpiq is continually developing new integrations. Moreover, we make new functionality available for our customers with every software update.

Your remote energy controller

Quinn load management is not only an invisible brain inside the chargers, but it also gives you end-to-end visibility and control of your charging operation and overall energy consumption.

You can prioritise charging stations and enable some chargers to operate faster than others.
You will see live data in the system and can identify possible charging hiccups, thus ensuring complete customer satisfaction.
You can do commissioning and modification of important parameters remotely. For example, you can decrease or increase the house connection.
