Laborelec has been selected to monitor the performance of 75 electric vehicles

A Dutch consortium consisting of the city of Rotterdam, Stedin, and Eneco has selected Laborelec to monitor 75 electric vehicles (EV). The goal is to gain insight in the vehicles’ energy consumption, their energy exchange with the electrical grid, and the loading behaviour of their batteries. Laborelec’s experience with EVs was a main contributor to its selection. Our experts are actively involved in EV research; for instance in the Flemish LINEAR project. We are also conducting an EV monitoring campaign for Electrabel and Cofely Services.

Presence detection lighting for bicycle paths

Grid operators and public authorities are looking for ways to reduce the energy consumption of public lighting. One area of research focuses on lighting up bicycle paths only when cyclists are actually using them. Together with EANDIS, the grid operator of the Flemish region in Belgium, Laborelec is testing whether such a system can be implemented using LED luminaires and presence detection sensors.

LED technology enables rapid on/off operation

EANDIS and Laborelec have equipped a test path in order to evaluate the new system’s potential. The setup features LED luminaires that not only switch on instantly but are also much more resistant to on/off operation. Such a setup would not be possible with traditional lighting technologies, since they require several minutes to reach their full luminous flux. In addition, with traditional technologies, continuous on/off operation results in significant wear.

‘We monitor the installation’s performance and compare its results with those of traditional systems,’ states Jean-Michel Deswert.
‘Initial measurements have shown that the presence detection system combined with LED technology consumes 45% less energy
than traditional lighting.’

Testing a wide variety of sensor technologies

‘To enable presence detection, a number of sensors will be placed in between the lights along the path,’ explains Deswert. ‘The goal is to test numerous sensor technologies—including radar, infrared, and camera-based ones—to identify which one is the most accurate and reliable. In addition, we are in the process of determining how many detectors need to be installed.’

Presence detection systems enable savings up to 45% compared to traditional lighting systems.

Outdoor lighting lab – researching LED luminaires for public lighting in real-life conditions

Laborelec has created an on-site test environment with fourteen LED luminaires
from different manufacturers to assess the use of LEDs for public lighting under
actual operating conditions. Our tests focus on evaluating both the luminous
efficiency and durability of the individual units.
