Several battery technologies exist amongst other available electric energy storage technologies for both large and small-scale energy storage applications. Lead-acid and Li-ion batteries are presently the two most widely used battery storage technologies for small scale applications. Though environmental temperature greatly affects the operation pe...

... to heat reduces longevity. Manufacturers of Li-ion battery usually gives the operating temperature of lithium -ion battery to range from 0 to 45°C for charging operations and -20 to 60°C for discharging operations. However, in their report [26] claims that the optimal temperature range for lithium -ion battery operation is between 15 to 35°C. Fig. 3 is a graphical summary of [26] analysis. The rate of chemical reactions to produce electric power in Li-ion batteries reduces as temperature decreases. According to [27], [28] and [29], decrease in temperature causes contraction of the electrode materials; which slows down ion movements in the intercalation spaces. As this continues, ...

Accurate online state-of-health (SOH) estimation can improve the operational efficiency of lithium-ion batteries (LIBs) and ensure the safety of energy storage systems. However, the complex electrochemical properties of LIBs make accurate SOH estimation challenging. To overcome this challenge, we propose a secondary structural ensemble learning (SS...

Combined Heat and Power (CHP) systems are considered as a transitional solution towards zero carbon emissions in the next couple of decades. The current CHP systems are mainly controlled by thermal led strategy, that is, the electrical power generation depends on the thermal energy demand. The mismatch between the power generation and load demand l...

Batteries in energy storage systems are exposed to electrical noise, such as alternating current (AC) harmonics. While there have been many studies investigating whether Lithium-ion batteries are affected by AC harmonics, such studies on Nickel Metal Hydride (NiMH) batteries are scarce. In this study a 10 Ah, 12 V NiMH battery was tested with three...

... The rate at which lithium ion batteries degrade is not only closely associated with the cell chemistry and design, but also to the operating conditions to which it is subjected. In general, most lithium ion battery chemistries have an ideal working temperature range of 15e35 C [3]. The battery management system (BMS) regulates the temperature of each cell to stay in this range in order to prevent the battery from overheating or freezing. ...

An ageing test procedure was developed in this work in order to assess the influence of battery degradation effects, occurring during electrical cycling of lithium-ion batteries at elevated temperatures, on the electrical and mechanical properties of the cells and on their safety behaviour under mechanical quasi-static crush loading. Commercial 41 A h NMC-LMO/graphite pouch cells were charged and discharged at 60 °C for 700 cycles at 1 C in an SOC range between 10 and 90%. Electrical properties of these batteries were evaluated every 100 cycles at room temperature. By the end of the cycling procedure, a 27% reduction of the initial capacity was observed. The behaviour of the fully charged aged cells under a quasi-static mechanical load was examined in a series of indentation tests, using a flat impactor geometry. This behaviour was compared to that of fresh cells. Test results show that all investigated electrically cycled cells exhibited a slight decrease in stiffness. Aged batteries also failed at higher compressive strengths and larger deformations. Post-mortem analysis of the aged cells was performed as a next step using scanning electron microscopy and the occurred degradation effects were evaluated in order to explain the changes observed in the battery electrical and mechanical properties.

High-temperature superconductor (HTS) based devices have the potential to be useful technologies for space applications, allowing very high current transfer and magnetic field generation. However, HTS technology requires cryogenic temperatures (<90 K) to operate, and it is not well understood if and how this can be achieved for HTS devices integrated into space vehicles. In this study, the thermal and power performance of a hypothetical 3U CubeSat equipped with an HTS magnetic coil is explored over a range of orbits around the Earth. After eliminating the possibility of passive cooling this close to a planetary body, a cryocooler was deemed necessary to maintain the required temperatures and was included in the simulations. The results show that the best strategy for maintaining the cryogenic operating environment is to maximise the power availability to the cryocooler from solar panels. This approach increases the volume-averaged temperature of the satellite, but the benefits of increased power outweigh the cost of a decreased cryocooler efficiency. This work demonstrates that a 1 T magnetic field can be generated with an HTS electromagnet in a space environment on a small satellite, enabling the use of HTS for space applications such as electric propulsion and energy storage.
