We’ve shared a guide explaining load balancing, how electricity is distributed and the importance of understanding how it works.
What is load balancing?
Load balancing distributes charging capacity equally across all charging ports in a specific location, optimising performance and utilising the limited power in a multi-charging-point location.
Operating an EV charging station requires a power source, and the extent of that source depends on the location, to carry the charging power across all charging ports. Load balancing distributes the available power capacity equally to active charging stations, providing optimal performance for anyone using the chargers.
Our role at Devitech is to visit your site, perform an assessment and speak with a distribution network operator (DNO) to assess the available power. Our assessment calculates how many chargers you could run, such as two or ten and the possibility of load balancing. You can distribute the power through static or dynamic load balancing.
Static load balancing
Static load balancing is when you have a specific amount of power and can never exceed a certain limit with the number of chargers you have. As there is a limit to the amount of power, the electricity is distributed evenly between the many charges you have. It’s simple to program, with only a network needed.
Dynamic load balancing
Dynamic load balancing uses a CT charger, clamped to the power supply, to measure the available power. For example, it takes the power to 95% with a 5% buffer. 95% of the available power is distributed across your network. The available power depends on what’s currently being run using your power source, such as electrical equipment in your building. Whatever power is available is distributed accordingly to the EV chargers on your site.
Why is load balancing important for EV chargers?
Load balancing maximises charging site efficiency, ensuring each charge point has suitable electrical output. It also helps the charging service provider access electricity from the grid during quieter periods and off-peak times and store it on site for later use.
Load balancing helps EV service providers avoid additional taxes from the grid during peak demand times because it uses the energy saved in quieter times.
We like to make load balancing simple for you. Our team will arrange a site assessment, look at the power availability on your site, make a deal with the DNO and find the best future-proof solution for you.
