How to stop your workplace EV chargers from fighting over power

Dynamic load balancing allows businesses to expand their EV charging capabilities without costly infrastructure upgrades. It’s smart, scalable, and designed to make the transition to electric vehicles easy and affordable.

 

What is Dynamic Load Balancing (DLB)?

More employees and visitors are driving electric vehicles, and naturally, they all want to plug in. But no matter the size or location, every building will have a limit to their power supply. If too much power is drawn at once, you risk overloading circuits, tripping breakers, and facing costly infrastructure upgrades.

Dynamic load balancing monitors the energy flow to each charger and adjusts it based on real-time usage. Whether it's two vehicles or 20, dynamic load balancing can evenly distribute power across all chargers, prioritising where necessary.

 

Benefits of Dynamic Load Balancing

• No risk of overloading – it keeps your building and the local power supply safe.
• No need for expensive building work – it saves you money from the get-go.
• Charge more EVs without upgrading your existing power supply.
• Scalable solution, allowing you to add more EV chargers in the future.
• Remotely monitor how much electricity you’re using and adjust things to suit you.

 

How does it work?

It’s really not as complicated as you might think. In simple terms, DLB shares the available power between all active EV chargers. Instead of each charger pulling maximum power all the time (which your site’s electricity might not handle), the system adjusts how much power each vehicle gets based on what’s available. Here’s how it plays out:

• If fewer cars are charging, each one gets a bigger share of the power available.
• If more cars plug in, the system evenly distributes power without exceeding your site’s limit.
• If other heavy-duty equipment is running, the system prioritises and adjusts EV charging accordingly, so that your business continues to operate smoothly without power disruptions.

 

Here’s an example: if a building has 40 amps available but 10 amps are prioritised for use by the building itself, the meter will report this to our system and the EV charging points will share the remaining amount amongst each other.

In this example, the chargers are sharing 30 amps, and those 30 amps are “dynamic,” so if two electric cars are charging, they each get 15 amps, but if there’s only 1, that car would get the full 30 amps.

In other words, it's a smart and very flexible approach to power supply which protects the stability of the power grid and of the entire EV charging process.

 

How much power do you need to charger an electric car?

A home EV charger typically delivers around 7.4 kW of power. To put that in perspective, a microwave uses around 1 kW of power. So, while charging an electric vehicle uses more energy than reheating your leftover pizza, it’s still easy to manage—especially if you’re using intelligent technology like dynamic load balancing.

An electric car uses roughly 0.316 kWh per mile on average. With the average UK driver covering 19 miles a day, that means your car uses around 6 kWh of electricity just to keep up with the daily commute. Over the course of a month, that adds up to roughly 180 kWh of electricity.

Dynamic load balancing becomes crucial when your company has several EV chargers. It helps to prevent any load on the grid or your electrical system by making sure that each charger receives precisely the right amount of electricity at the right time. This way, you can charge multiple vehicles without worrying about overloading the system—keeping everything balanced and efficient.

 

Why does your workplace need it?

For businesses like yours, efficiency, cost control, and scalability are key when investing in EV charging infrastructure. Whether you’re managing a fleet or offering EV charging to employees and visitors, dynamic load balancing is a data-driven solution that optimises power distribution, helping you maximise your charging capacity while keeping energy use in check.

1. Prevent power overloads

Your workplace already has a limited power capacity, and adding multiple EV chargers can put strain on your supply. Without DLB, plugging in several EVs at once could trip circuits, disrupt operations, or even damage equipment.

With dynamic load balancing, your chargers automatically adjust to ensure total energy consumption stays within safe limits, meaning no blackouts, no downtime, and no frantic calls to your electrician.

 

2. Avoid expensive upgrades

Upgrading your site’s power capacity to accommodate more EV chargers can cost thousands in infrastructure changes. Dynamic load balancing helps you work within your existing electrical setup by intelligently managing power distribution. That means you can offer more charging without increasing your energy tariff or needing major electrical work.

 

3. Charge more EVs without upgrading your supply

Expanding your EV charging network used to mean bigger cables, new meters, and higher electricity bills. Not anymore. With DLB, you can install multiple chargers without upgrading your grid connection—it simply allocates power dynamically so every plugged-in vehicle gets the right amount of charge based on availability.

For example, instead of needing a 110kW power supply to run five 22kW chargers, dynamic load balancing can let them share a smaller supply more efficiently.

 

4. Improved energy management

Dynamic load balancing doesn’t just balance the load between chargers—it can help your business manage energy consumption more effectively. By having full visibility over your energy use, your business can cut costs and improve sustainability.

 

“We’ve developed our dynamic load balancing technology because we know businesses want to support EV charging but face the challenge of expensive power upgrades. Energy supply shouldn’t be a barrier to going electric. Our dynamic load balancing kit makes it easy for businesses to install multiple chargers and distribute power smartly, without overloading their supply. We’re excited to bring this to market to make making EV charging more accessible, cost-effective, and ready for more EVs on the road.” - Tom Bloor, Managing Director

 

By 2030, every new car sold in the UK will be electric. With over 1.4 million EVs already on the road and one in five new cars now electric, demand for charging infrastructure is only increasing. Without smart energy management, businesses could face rising costs, power limitations, and operational challenges.

Dynamic load balancing helps you make the most of your existing power supply—so you can charge more EVs without costly upgrades. Whether you're running a fleet, adding workplace chargers, or prepping your site for the future, it keeps charging efficient, affordable, and stress-free.
