The main profit models of the global charging pile industry are: borrowing electricity reform, wholesale + retail electricity profit model; quite satisfactory, charging charging service fee profit model; changing the way of thinking, aiming at the blue ocean model of the parking market; open thinking, charging service ecosystem Profit model.
Where a profitable application of energy storage requires saving of costs or deferral of investments, direct mechanisms, such as subsidies and rebates, will be effective. For applications dependent on price arbitrage, the existence and access to variable market prices are essential.
Although academic analysis finds that business models for energy storage are largely unprofitable, annual deployment of storage capacity is globally on the rise (IEA, 2020). One reason may be generous subsidy support and non-financial drivers like a first-mover advantage (Wood Mackenzie, 2019).
Although electricity storage technologies could provide useful flexibility to modern power systems with substantial shares of power generation from intermittent renewables, investment opportunities and their profitability have remained ambiguous.
Building upon both strands of work, we propose to characterize business models of energy storage as the combination of an application of storage with the revenue stream earned from the operation and the market role of the investor.
Investment in energy storage can enable them to meet the contracted amount of electricity more accurately and avoid penalties charged for deviations. Revenue streams are decisive to distinguish business models when one application applies to the same market role multiple times.

The most practical protection option is usually an external, fixed firefighting system. A fixed firefighting system does not stop an already occurring thermal runaway sequence within a battery module, but it can prevent fire spread from module to module, or from pack to pack, or to adjacent combustibles within the space.
In such application, the energy pile and its surrounding soil are subjected to temperature changes that could significantly affect the pile–soil interaction behaviour. The aim of this paper is to review the current state of knowledge on the design of energy piles in terms of the geostructural and heat exchanger functions.

Energy piles offer a promising and eco-friendly technique to heat or cool buildings. Energy piles can be exploited as ground heat exchangers of a ground source heat pump system. In such application, the energy pile and its surrounding soil are subjected to temperature changes that could significantly affect the pile–soil interaction behaviour.
The heat exchange capacity of the energy pile depends on the thermal resistivity of the pile and the surrounding soils. The consequently, their thermal behaviour could be different. The pile Lennon et al., 2009; Wood et al., 2010) is not in good agreement with the theoretically calculated value.
A comprehensive review of this aspect has been carried out by Loveridge and Powrie (2013). Other factors, such as the existence of ground water flow, geometrical configuration of the heat exchange pipes in the pile and pile layout, can also affect the performance of the heat exchanger function of the energy pile.
The energy pile concept can be considered as a to cool/heat buildings is the heat pump (HP) system. Unlike the vast cost of drilling boreholes and the land area required for borehole could be readily employed almost anywhere. Although HPs are installation.
ESSs could be categorized according to multiple factors, including, intended applications, storage duration, storage efficiency, etc. Major ESS have been discovered and classified as thermal energy storage (TES) (such as thermo-chemical energy storage), mechanical energy storage (MES) (such as flywheel energy storage), chemical energy storage.

Given that traditional natural convection or air-cooling techniques cannot meet the heat dissipation requirements of high-current charging cables, the method of directly immersing the cable core in insulating heat-conductive oil for active liquid cooling becomes the inevitable choice.
However, for high-power fast charging and superfast charging, active liquid cooling that combines pumps and coolants (such as water and dimethyl silicone oil) needs to be used . In addition, the phase-change heat transfer technology of coolants also should be introduced as the charging power increases in the future [12, 13].
The charge power of household charging stations using the alternating current (AC) is commonly within 10 kW, referred to as a trickle charge. A system that charges vehicles with direct current (DC) of 50–60 kW is called a fast-charging system, and those charging vehicles with the power higher than 150 kW are termed superfast charging systems.
