The effect of charging and discharging lithium iron phosphate-graphite cells at different temperatures on their degradation is evaluated systematically. The degradation of the cells is assessed by using 10 charging and discharging temperature permutations ranging from -20 °C to 30 °C. This allows an analysis of the effect of charge and discharge temperatures on aging, and their associations. A total of 100 charge/discharge cycles were carried out. Every 25 cycles a reference cycle was performed to assess the reversible and irreversible capacity degradation. A multi-factor analysis of variance was used, and the experimental results were fitted showing: i) a quadratic relationship between the rate of degradation and the temperature of charge, ii) a linear relationship with the temperature of discharge, and iii) a correlation between the temperature of charge and discharge. It was found that the temperature combination for charging at +30 °C and discharging at -5 °C led to the highest rate of degradation. On the other hand, the cycling in a temperature range from -20 °C to 15 °C (with various combinations of temperatures of charge and discharge), led to a much lower degradation. Additionally, when the temperature of charge is 15 °C, it was found that the degradation rate is nondependent on the temperature of discharge.

“…In the work of Liu, Gao, and Cao (2012) the preferable temperature also seems to lie between 0 and 25ºC. The LFP batteries in Ruiz et al (2017) show different responses depending on the cell charging temperature and the cell discharge temperature. In Groot et al (2015) the highest energy throughput over the life of an LFP cell is reflected for a cell that is partially charged (60%) at a rate of 4C and discharged at 4C at a surprisingly high temperature of about 50ºC and the lowest throughput is reflected for a cell charged at 3.75C to 100% and discharged at a much slower 1C rate with the cell temperature maintained between 21 and 28ºC.…”

Technical and economic potential of energy recovery and re-use on board surface mining haul trucks

This thesis investigates the technical and economic feasibility, as well as emissions related benefits, of incorporating energy recovery systems (ERSs) on board mine haul trucks (MHTs) used in surface mining. More specifically it aims to answer the research question: "What practical combination of hybrid drive topology, and energy storage technology, capacity and use on board mine haul trucks, will maximise the economic benefit of energy recovery and re-use, considering variation in haul route characteristics and the time value of money through the life of a surface mining project?" To answer this question, a simulation program was developed and progressively expanded to conduct each of four main stages of the research. In Stage One, the simulation program was used to determine the potential of various technologies to reduce the fuel consumption per tonne mined for each of a range of pit depths. Appropriately informing the simulation program required identifying and quantifying representative input values for truck, haul route, and ERS characteristics. Truck and haul route characteristics determine the energy recovery rate and amount of energy recoverable to the trucks' DC-links. ERS characteristics enable evaluating the potential and practical implications of each ERS technology to capture this recovered energy. ERS technologies considered include ultra-capacitors, lithium-ion capacitors, chemical batteries, and electro-mechanical flywheels (EMFWs).
