The ultimate bearing capacity of the W-shaped energy pile was 12.8 kN. However, the ultimate bearing capacity of the U-shaped energy pile after five heating–cooling cycles was 11.9 kN and presented a significant reduction reaching up to 9.2% of the capacity of RP3.
According to the above criterion, the ultimate capacities of the piles were estimated to be 43.5 and 41.5 kN for temperature variations of Δ T = 0 and − 7 °C, respectively. Due to the small displacement for temperature variations of Δ T = + 23 °C, the ultimate capacity could not be estimated accurately.
The influence of thermal loads on the ultimate bearing capacity of energy piles is examined. Five laboratory model tests were carried out to investigate piles equipped with U-shaped and W-shaped heat exchangers in dry and saturated sand.
A notable fact when integrating solar cells and energy storage devices is the mismatch between them, 8 for example, a battery with a capacity much more higher than what the PV cell can provide per charging cycle.
Regarding the energy management system, battery charging is the priority. However, in some cases if the battery is above the minimum voltage and PV power is not enough to satisfy the load, the PV production will go directly to the load and the battery discharges.
Single cycle early prediction of capacity’s remaining-useful-life: 8.6% MAPE. Combines the datasets of Severson etal. (2019) and Attia etal. (2020) to 165 LFP cells. There is a large demand for models able to predict the future capacity retention and internal resistance (IR) of Lithium-ion battery cells with as little testing as possible.
