“…Secondly, scholars have mainly used the cost-effectiveness analysis method to analyze the commercial value and social value of battery energy storage, although the research perspective is different [15,19,[42][43][44][45][46]. For example, Zakeri and Syri used the life cycle cost (LCC) analysis to analyze the economics of different forms of battery energy storage [14].…”

Nowadays, many countries are actively seeking ways to solve the energy crisis and environmental pollution. New Energy Vehicle (NEV) has become an important way to solve these problems. With the rapid development of NEV, its batteries need to be replaced with new batteries after 5–8 years. Therefore, whether the second use of NEV’s battery has commercial or social value becomes a research hotspot. The innovation of this paper is to use the cost-benefit method to determine the value influencing factors of NEV’s battery second use, and use system dynamics to perform scenario simulation analysis. The methods used in this paper are the cost-benefit method and system dynamics method. Firstly, this paper systematically analyzes the cost and benefit factors that affect the second use value of China’s NEV batteries and uses system dynamics to establish the relationship and value model among various factors. Then, this paper compares the value of battery energy storage between old batteries and new batteries. According to the cost-income factor analysis, this paper eventually selects specific factors and uses VENSIM software to carry out the multi-scenario simulation. The results show that NEV’s battery second use has commercial and social value compared to new battery energy storage. Moreover, battery cost, government subsidies, and electricity prices are three important factors that affect the second use value of China’s NEV battery. Changing the government’s cash subsidy methods, such as providing free batteries or combining new energy to reduce on-grid tariffs, will help increase the second use value of the NEV battery. In the future, the second use value of China’s NEV battery industry will be more significant, with the update of the technology, the surge in the number of NEV’s used batteries, and government support.

“…NEV's battery second use in energy storage is a systematic process [3,6,20,28,45]. It relates to several parts, such as battery energy storage station, battery suppliers (new battery provider, old battery provider), new energy power plant, power grid, used battery recyclers, and power users [37,39,41,60,61], as shown in Figure 3.…”

“…The correctness of the thermal analysis model and the thermal management scheme of battery were analyzed and verified by simulation and experiment. According to the analysis of the research status at home and abroad, the thermal characteristic model of the battery can be simplified by combining the formulas; the single battery is regarded as an anisotropic material, and its calculation model is measured by classical theoretical model or experiment [13].…”

In order to meet the needs of actual working conditions and people's expectations, electric vehicles using lithium ion batteries as power sources are not completely comparable to traditional fuel vehicles in terms of endurance mileage and driving performance. The main technologies of battery thermal management system are summarized, and the research status of air cooling, liquid cooling and phase change material cooling and heat generation characteristics of batteries are summarized. Based on CFD (Computational Fluid Dynamics) analysis method, the model of liquid cooling and heat dissipation system of batteries is established, and the flow of cold fluid in cooling channel and the temperature change of batteries are analyzed. Based on the simulation results of the original model, the existing problems are analyzed and the cooling passage structure of the cooling system is optimized. The temperature field and flow field of the improved scheme are simulated, analyzed and compared. The results show that, compared with other kinds of batteries, lithium ion batteries have many advantages, such as high voltage, light weight and no pollution. However, the working performance of lithium ion is closely related to the working temperature. When the working temperature is too high, the working safety of lithium ion is not guaranteed; when the working temperature is too low, the chemical reaction rate decreases, and the capacity of lithium ion batteries decreases, which has adverse effects on the endurance mileage and driving performance. Therefore, it is necessary to study the temperature field control of batteries to ensure the normal operation of electric vehicles.

Summary The fading characteristics of 60 Ah decommissioned electric vehicle battery modules were assessed employing capacity calibration, electrochemical impedance spectroscopy, and voltage measurement of parallel bricks inside modules. The correlation between capacity and internal resistance or voltage was analyzed. Then, 10 consistent retired modules were packed and configured in a photovoltaic (PV) power station to verify the practicability of their photovoltaic energy storage application. The results show that the capacity attenuation of most retired modules is not severe in a pack while minor modules with state of health (SOH) less than 80% bring about the retirement of the whole pack as a result of the buckets effect. There is no obvious correlation between capacities of retired battery modules and their lithium‐ion diffusion coefficients or charge transfer resistance or ohmic resistance, whose reliability is low as the consistency indexes of decommissioning battery modules. The maximum off load voltage difference ΔUmax at low state of charge (SOC) values has a good negative linear correlation with the capacity of retired modules, suggesting that the ΔUmax value at low SOC values can be considered as a characteristic index for fast classification of retired battery modules for large‐scale second‐life application. A PV power station equipped with retired battery energy storage system (RBESS) can maximize the photovoltaic self‐utilization rate. It is an important way to reutilization of retired battery that RBESSs are configured with distributed PV power stations.
