Zaptec and Spirii unveil new smart charging algorithm

Zaptec and Spirii have collaboratively developed a new algorithm named PowerDelta, which will make EV charging even more energy- and cost-efficient. The algorithm ensures that meter data from the chargers are only transmitted when there are deviations in the power supply instead of being sent at fixed intervals. This will help data centres avoid unnecessary power consumption for data sharing, thereby significantly reducing the need to transport large data volumes between systems.

Spirii, a global provider of EV charging solutions, has teamed up with Zaptec, to develop a new algorithm designed to significantly improve energy and cost efficiency in electric vehicle (EV) charging.

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 centres cut unnecessary power consumption associated with data sharing and minimizing 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%.

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.

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.

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 minimize the energy consumption associated with our operations.
