The power system (PS) has the problem of grid connection of energy storage (ES) system. When the ES of the communication base station (BS) is associated with the power grid, relevant control strategies are formulated to schedule the base station energy storage (BSES). The total cost required during the scheduling period is determined using the lease income model. In the dispatching process, the BSES is applied to the peak load shifting (PLS) dispatching and economic dispatching of the PS. It is optimized by particle swarm optimization (PSO) algorithm and improved bare bone particle swarm optimization (BBPSO) algorithm. The constructed rental income model is used to calculate the total cost required during the scheduling period. In the dispatching, the BSES is applied to the PLS dispatching and economic dispatching of the PS. This model is optimized by PSO algorithm and improved BBPSO algorithm. The findings indicate that the BSES has good PLS capability. The larger the BS is, the more obvious the charging and discharging situation is. When the time is 4 h, the output load of 150,000 BSES is 486.67 MW, 341.14 MW more than that of 100,000 BSs. The discharge depth affects the lease cost, and the best discharge depth is 0.4. At this discharge depth, the larger the BS scale is, the greater the costs. In improving the performance of BBPSO algorithm, the model has the minimum convergence iteration of 15, with the best convergence effect. In the economic dispatching of PS, the total cost of accessing 200,000 BSs to store energy is 846.4658 million per year, which saves 367.4591 million. The suggested approach can effectively lower PS costs and increase stability.

“…Similarly, Bank et al also confirmed that the coulombic and energy efficiencies of the LTO battery decreased sharply with the increase of current density, which does not meet the criterion of 48 V start/stop. Other workers also compared the charge–discharge and cycling performance of prismatic cells with NCM111, LFP, and LMO cathode materials. , Basically, every cathode candidate demonstrates its own merits and demerits. The NCM111-based cell exhibits better performance in charge–discharge rate, specific energy, and discharge characteristics at high/low temperature, while the LFP candidate has obvious advantages in long cycling.…”

It is a bottleneck issue for state-of-the-art start/stop batteries used in commercialized electrical vehicles to have a long cycling life, high power output, and understanding safety performance. In this work, we fabricate prismatic cells to unravel how these tradeoffs can be balanced based on the material and cell design. Small-particle Li[Ni1/3Co1/3Mn1/3]O2 ternary materials with surface modification and isotropous graphite are respectively employed as cathode and anode to provide super power density. Ceramic-coated separators with high permeability and wide-temperature electrolytes with high conductivities enable the safety and cold cranking performance. Ultrathin-coating electrodes and whole poles are achieved to shorten the transferring distance of Li ions and promote the efficiency of Li intercalation and deintercalation kinetics, which demonstrates the lower internal resistance and current density. By unlocking charge transfer limitations, the cell presents a high discharge power density of >5000 W/kg at 25 °C, a 50% SOC (state of charge), and excellent cold cranking characteristics at −30 °C. A capacity retention of 3 C (100% depth of discharge, DoD) cycling approaches 80% over 6800 cycles at 25 °C and 4300 cycles at 45 °C. Also, a capacity retention of cycling at room temperature according to worldwide light vehicle test procedures reaches up to 92.3% over 6000 cycles with the energy throughput of 614.5 kWh and direct charge internal resistance does not soar with the cycling ongoing. The mechanism of the capacity loss is dissolved Ni, Co, and Mn, which results in irreversible loss of Li. The cell shows high safety characteristics by passing the 3 C overcharge and nail penetration tests. It is evident that the reported cell can be a promising commercialized candidate for 48 V start/stop and hybrid electric vehicle solutions.
