[PDF Version]In order to reduce the operation temperature of the charging pile, this paper proposed a fin and ultra-thin heat pipes (UTHPs) hybrid heat dissipation system for the direct-current (DC) charging pile. The L-shaped ultra-thin flattened heat pipe with ultra-high thermal conductivity was adopted to reduce the spreading thermal resistance.
Ma and Wang proposed using energy piles to store solar thermal energy underground in summer, which can be retrieved later to meet the heat demands in winter, as schematically illustrated in Fig. 1. A mathematical model of the coupled energy pile-solar collector system was developed, and a parametric study was carried out.
The energy piles combine the foundation piles with the heat exchange pipes, the latter being attached to the steel cage and embedded in the pile body, as illustrated in Fig. 1. In this way, the energy piles sustain the building load and hold the heat exchange pipes simultaneously.
The conventional practice of underground thermal energy storage is burying heat exchange pipes into pre-drilled vertical holes, referred to as the borehole thermal energy storage . Heat transfer occurs by circulating heat carrier fluid through the pipes. However, the cost of drilling deep holes can cause a breakdown of a project .
Energy piles, which embed thermal loops into the pile body, have been used as heat exchangers in ground source heat pump systems to replace traditional boreholes. Therefore, it is proposed to store solar thermal energy underground via energy piles.

Battery balancing aims to address these issues by: Equalizing the charge levels across all cells; Preventing overcharging or over-discharging of individual cells; Maximizing the usable capacity of the battery pack; Extending the overall lifespan of the battery; Designing a battery balancing system.
To counteract these challenges, EV manufacturers practice battery balancing to guarantee that all the cells within a pack are working at their given voltage, as well as charge levels. The two main types of EV balancing strategies are passive balancing and active balancing. Passive balancing is a simpler and more cost-effective method.
After performing cell balancing, each cell's SoC reaches 60 % (average SoC) which signifies that all cells have reached to same level or balanced. Therefore, SoC balancing is crucial in EV battery pack to increase the usable capacity. Fig. 3. Charge among five cells connected in series before and after SoC balancing.
Battery balancing works by redistributing charge among the cells in a battery pack to achieve a uniform state of charge. The process typically involves the following steps: Cell monitoring: The battery management system (BMS) continuously monitors the voltage and sometimes temperature of each cell in the pack.
Individual cell voltage stress has been reduced. This study presented a simple battery balancing scheme in which each cell requires only one switch and one inductor winding. Increase the overall reliability and safety of the individual cells. 6.1.
One of the most important parameters of estimation the performance of battery cell balancing is the equalization time. Other parameters such as power efficiency and loss are related to the balancing speed.
Consequently, the authors review the passive and active cell balancing method based on voltage and SoC as a balancing criterion to determine which technique can be used to reduce the inconsistencies among cells in the battery pack to enhance the usable capacity thus driving range of the EVs.

As of the end of 2023, cumulative private investment in medium- and heavy-duty vehicle charging infrastructure in the United States amounted to USD 4.2 billion. Industry will certainly also play a major role in HDV charging infrastructure development.
In dense urban areas, in particular, where access to home charging is more limited, public charging infrastructure is a key enabler for EV adoption.
All US states, Washington DC, and Puerto Rico are participating in the programme, and have already been allocated USD 885 million in funding for 2023 to support the build-out of chargers across 122 000 km of highway (see Policy support for EV charging infrastructure).
Electric trucks and buses will rely on off-shift charging for the majority of their energy. This will be largely achieved at private or semi-private charging depots or at public stations on highways, and often overnight.
As the market penetration of EVs increases, public charging becomes increasingly important, even in these countries, to support EV adoption among drivers who do not have access to private home or workplace charging options. However, the optimal ratio of EVs per charger will differ based on local conditions and driver needs.

For harvesters embedding a single levitating magnet inside the container and attaching multiple coils (third category), six studies,,,,, propose cylindrical containers that include cylindrical (Fig. 3 a-c,e) and ring magnets arranged along a shaft (Fig. 3 d).
Some research efforts have been conducted so far to develop optimized motion-driven electromagnetic energy harvesters using magnetic levitation architectures. The addressed optimization methodology followed by each author is presented in Table 12.
Low excitation magnitudes drive a linear behaviour of the motion experienced by the levitating magnet, resulting in a response with a single periodic attractor (unique solution associated with any initial condition) as depicted in Fig. 7 a.
