Data Logging – Investigating Power Capacity for EV Chargers

Data Logging – What is it and how does it help? 

Data logging in building complexes is a crucial aspect of building management systems (BMS) or building automation systems (BAS). It involves the collection and recording of data related to various building parameters to monitor and optimize energy usage, ensure occupant comfort, and improve overall operational efficiency.

Data logging helps in identifying peak energy consumption periods within the building complex. This information is crucial for optimizing the deployment of EV charging infrastructure to avoid overloading the electrical grid during peak hours.

How long do you need to collect data for? 

We attend buildings on request & install data loggers for a period of 7 to 14 days to collect the power usage of the building to determine its leftover capacity and provide reports to the client. This is important when buildings are looking to install future infrastructure for EV charging.

Based on the data collected & report provided, building managers can assess the overall electrical capacity and identify whether there is a need for infrastructure upgrades to support additional loads from EV charging stations.

This information is critical for ensuring that the building’s electrical infrastructure can accommodate the increased demand associated with electric vehicle charging.


Data logging in building complexes is a fundamental tool for sustainable and efficient facility management. By leveraging the insights gained from monitoring and analysis over a 7-day period, building managers can enhance operational efficiency, reduce costs, and create more comfortable and sustainable environments for occupants.
