Danish EV charging solution provider Spirii and Norwegian technology company Zaptec have collaborated on a new smart charging algorithm to reduce data volumes.

The algorithm, named PowerDelta, is designed to make the operation of an EV charging network more energy efficient and cost effective.

With the PowerDelta algorithm, EV chargers transmit meter data only when deviations in power supply occur, as opposed to the industry norm of sending data updates every second.

With this change the volume of data transmitted can be significantly reduced, helping data centres reduce unnecessary power consumption associated with data sharing and minimising the transfer of large data volumes between systems.

It also eases the burden on the telecom network, ultimately lowering the operational costs associated with data handling for charge point operators.

For example, if a charging station delivers 11kW, data updates will only be triggered by significant changes, such as a deviation of 100W, rather than transmitting the same meter reading every second.

Thus during an 8-hour overnight charge, the number of updates can be reduced from approximately 30,000 to as few as 100, amounting to a data processing reduction of over 99%.

Torben Fog, CIO and co-founder of Spirii, describes the PowerDelta algorithm as a “game-changer”.

“Smaller data volumes mean lower costs for data management, which is great news for charging operators. The algorithm helps save both energy and money in powering electric vehicles.”

The PowerDelta algorithm builds on the Open Charge Point Protocol (OCPP), offering an enhanced solution ensuring seamless integration and interoperability across platforms for charge point operators worldwide.

Knut Braut, CTO of Zaptec, adds that the demand for scalable and efficient charging infrastructure is more pressing than ever.

“The PowerDelta algorithm offers a vital solution to this challenge by providing a smarter way to manage charging networks. Our focus remains on collaboration and innovation, working closely with industry partners to continuously push technological boundaries. Through these efforts, we aim to enhance the efficiency of our charging infrastructure and minimise the energy consumption associated with our operations.”
