Summary of the energy storage charging pile puncture test experiment

Electrochemical energy storage has become an increasingly important and growing topic which started already in the 18th century, when Alessandro Volta built his "pile" consisting of alternating cathode and anode layers, separated by a tissue and connected by an electrolyte. While the original aim of Volta was to perform biological experiments rather than energy storage, the …

What is an energy pile?

Energy piles, also called thermo-active piles, are an alternative solution for heating and/or cooling needs. Energy piles are double purpose structures that allow transferring the loads from the superstructure to the soil and that integrate pipe circuits allowing heat exchange between the pile and the surrounding ground.

How long does a model energy pile keep temperature constant?

The model energy pile EP1 temperature was increased from 22°C to 37°C in 10 minutes (ΔT=15°C) and the model energy pile EP2 temperature from 22°C to 52°C (ΔT=30°C) in 10 minutes. Then, the temperatures were kept constant for 110 minutes. The two energy piles were then Chapter 4: Numerical modelling of energy piles 129

Where are instrumented energy piles placed?

The position of the two instrumented energy piles was chosen in order to highlight the effect of the end restraints: one instrumented energy pile is placed under the foundation slab (P29, Figure 2-19), while the second one is placed under a lateral wall (P18, Figure 2-19), thus providing a much stiffer head restraint.

When was a full-scale energy pile installed?

An experimental full-scale energy pile was installed in 2010 (Figure 2-5 a) next to the Coriolis building at the Ecole des Ponts ParisTech, Marne-la-Vallée, France. This pile was built at the same time with the foundation system of the building.

Can energy piles meet building needs?

The Sept Sorts case study monitored the behavior of an energy foundation for one year before and one year after its geothermal activation. The results obtained up to now confirm the feasibility of energy piles for meeting both the building’s structural and heating/cooling needs.

What is the axial load of energy piles?

Results indicate that the highest thermal axial load appears in the lower part of the pile and is equal to -153kN when heating the pile by 10°C and 149kN when cooling the pile by 10 °C. The small Design and execution of energy piles: Validation by in-situ and laboratory tests 138
