ENERGY EFFICIENCY TEST BENCH

This energy efficiency test bench offers the possibility of optimising the energy consumption of communicating objects for IOT, 5G and beyond, by enabling the precise measurement of the energy impact of electronic systems in a controlled environment thanks to the choice of low-power hardware and software architectures. One of the objectives is to limit the frequent recharging of batteries and maximise their lifespan. Knowing the AC/DC energy consumption of objects also makes it possible, depending on their use, to size ambient energy recovery technologies (solar cell, motion, electromagnetic, etc.) to create energy-independent objects. This test bench provides a wide range of measurement options for improving the design of objects to enhance their performance and guarantee their reliability.

Applications

Measure and analyse the power consumed by a system or the sub-systems of a complex object.
- Measure current and voltage accurately over a wide dynamic range depending on the object's operating status (on, standby, communication, etc.).
- Measure accurate power consumption with sufficient bandwidth to avoid missing fast-moving digital events.
- Synchronise the energy consumption measurement with the powered object's software subroutines to optimise processor programming and maximise the object's battery life.
- Correlate load consumption with RF events and events in the object's sub-circuits.
- Examine the impact of power consumption as a function of RF interference with other wireless devices in a real or controlled environment by combining it with the telecommunications test bench (influence of the channel model, RF disturbances, interferers, electromagnetic pulses, etc.).
- Testing in difficult electromagnetic environments (C2EM: anechoic chamber, reverberation chamber)
Assessing the characteristics of a device's battery
- Visualise the evolution of the power consumed by an object as a function of its use and record it over a long period in a points file.
- Replay a recorded points file to check the performance of a battery and estimate its lifespan.
- Characterise the charging and discharging of a battery over time.
- Statistical analysis (CCDF) of power consumption.
