Spirii and Zaptec unveil new smart charging algorithm to revolutionise management of large data volumes

The PowerDelta algorithm enables chargers to transmit meter data only when deviations in power supply occur, as opposed to sending data updates every second which has been standard procedure in the industry until now.

This change drastically reduces the volume of data transmitted, helping data centers cut unnecessary power consumption associated with data sharing and minimising the transfer of large data volumes between systems.

For example, if a charging station delivers 11 kW, data updates will only be triggered by significant changes, such as a deviation of 100 W, rather than transmitting the same meter reading every second. During an 8-hour overnight charge, this adjustment can reduce the number of updates from approximately 30,000 to as few as 100—representing a data processing reduction of over 99%.

This shift not only improves data transmission efficiency but also eases the burden on the telecom network, ultimately lowering the operational costs associated with data handling for charge point operators.  

Torben Fog, CIO and Co-founder of Spirii, comments:

"The PowerDelta algorithm significantly reduces the amount of data transfers. This is a game-changer, enabling us to offer smarter charging solutions that alleviate pressure on both telecom networks and server farms. Smaller data volumes also mean lower costs for data management, which is great news for charging operators. In other words, the algorithm helps save both energy and money in powering electric vehicles."  

Knut Braut, CTO of Zaptec, says:

“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."  

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