The constant-current-constant-voltage (CCCV) strategy, which integrates the CC strategy and CV strategy, has become the most popular strategy for Li-ion battery charging [15]. In this strategy, a CC is injected into battery first and the battery terminal voltage increases until the maximum safe threshold is reached.
Abstract: Modular multilevel converter with battery energy storage system (MMC-BESS) is an excellent interfacing converter to integrate large-scale energy storage batteries and realize the interconnection between AC and DC grids. However, the previous state-of-charge (SOC) and state-of-health (SOH) management strategies for MMC-BESS normally work …

Lithium-ion batteries (LIB) are the mainstay of power supplies in various mobile electronic devices and energy storage systems because of their superior performance and long-term rechargeability [1] recent years, with growing concerns regarding fossil energy reserves and global warming, governments and companies have …
With the development of information technology and automation, intelligence techniques have gradually replaced manpower in container terminals. Automating container terminals can significantly improve the operation efficiency of the terminals and reduce energy consumption, time, and transportation resources. Automated guided vehicles (AGVs), …
When having a very long vehicle speed preview, the proposed framework may not take full advantage of the previewed information due to the intrinsic limitations of the MPC prediction horizon. Therefore, assuming that global vehicle speed is obtained, Zhao et al. [20], [21] proposed a two-stage/layer battery cooling control strategy. In the first ...

In this paper, a heating strategy using high-frequency alternating current (AC) is proposed to internally heat lithium-ion batteries (LIB) at low temperatures. The strategy aims to strike a good balance between rapid heating of the battery at low temperatures and minimizing damage to the battery''s lifespan without the need for an …
In fact, the power demand of handling equipment accounts for more than 70 % of the terminal, and the demand response strategy still has a huge benefit space (Mao et al., 2022). ... Dual-threshold battery-swapping strategy, the upper threshold is 50 %, and the lower threshold is 30 % (Ma et al., 2021). (3) This paper proposes a double-limit ...
mixed droop is proposed to HBESSs with considering the batteries. In decentralised control strategy, conventional V–I droop controller is utilised to high energy density battery to mainly supply the steady power, I–V droop controller is utilised to high power density battery to respond to power change and supply a few steady power.
The previous state-of-charge (SOC) and state-of-health (SOH) management strategies for battery energy storage system based on the modular multilevel converter (MMC-BESS) normally work separately. With the diversification and complexity of energy storage application scenarios in AC/DC hybrid grid, it is necessary to develop more flexible …
