“…Syntheses with complex technologies that operate under harsh conditions with rare ingredients and rigorous circumstances should be largely avoided in the mass production of batteries for GSES. Instead, facile, large-scale, energy-saving, pollution-free, and low-cost methodologies should be encouragingly implemented throughout the entire battery fabrication process . The internal situations of commercial-level batteries exhibit discrepancies with the lab-level ones and the major issues in the former are generally different from that in the latter.…”

Ever-increasing global energy consumption has driven the development of renewable energy technologies to reduce greenhouse gas emissions and air pollution. Battery energy storage systems (BESS) with high electrochemical performance are critical for enabling renewable yet intermittent sources of energy such as solar and wind. In recent years, numerous new battery technologies have been achieved and showed great potential for grid scale energy storage (GSES) applications. However, their practical applications have been greatly impeded due to the gap between the breakthroughs achieved in research laboratories and the industrial applications. In addition, various complex applications call for different battery performances. Matching of diverse batteries to various applications is required to promote practical energy storage research achievement. This review provides indepth discussion and comprehensive consideration in the battery research field for GSES. The overall requirements of battery technologies for practical applications with key parameters are systematically analyzed by generating standards and measures for GSES. We also discuss recent progress and existing challenges for some representative battery technologies with great promise for GSES, including metal-ion batteries, lead−acid batteries, molten-salt batteries, alkaline batteries, redox-flow batteries, metal−air batteries, and hydrogen-gas batteries. Moreover, we emphasize the importance of bringing emerging battery technologies from academia to industry. Our perspectives on the future development of batteries for GSES applications are provided.

“…Other safety-critical issues of batteries include thermal issues, over-charging or overdischarging, over-current, and so on [43][44][45][46][47][48]. Among these issues, thermal issues are considered to be the most critical.…”

“…The overdischarging does not cause a critical hazard; however, a battery cell can become a "dead cell" after extreme over-discharging. The over-discharging results in the internal electro-chemical effects which shorten the batteries' life cycle and safety [48,52,53]. A more detailed and scientific analysis of these issues, especially from the electrochemical viewpoint, can be found in [43][44][45][46][47][48][49][50][51][52][53].…”

Battery Management System for Unmanned Electric Vehicles with CAN BUS and Internet of Things

In recent decades, the trend of using zero-emission vehicles has been constantly evolving. This trend brings about not only the pressure to develop electric vehicles (EVs) or hybrid electric vehicles (HEVs) but also the demand for further developments in battery technologies and safe use of battery systems. Concerning the safe usage of battery systems, Battery Management Systems (BMS) play one of the most important roles. A BMS is used to monitor operating temperature and State of Charge (SoC), as well as protect the battery system against cell imbalance. The paper aims to present hardware and software designs of a BMS for unmanned EVs, which use Lithium multi-cell battery packs. For higher modularity, the designed BMS uses a distributed topology and contains a master module with more slave modules. Each slave module is in charge of monitoring and protecting a multi-cell battery pack. All information about the state of each battery pack is sent to the master module which saves and sends all data to the control station if required. Controlled Area Network (CAN) bus and Internet of Things technologies are designed for requirements from different applications for communications between slave modules and the master module, and between the master module and control station.

Battery energy storage systems (BESSs) are commonly used in smart grids. Voltage deviation or imbalance among cells generally exists in multi-cell battery packs. This work presents a study of the voltage deviation-related phenomena observed during the operation of a grid-tied BESS, Willenhall Energy Storage System (WESS), including the voltage deviation changes during full range cycle and the cut-off mechanism activated by it. Electroimpedance spectroscopy measurements and equivalent circuit modelling were conducted on the same type of cell as that used in WESS to obtain cell-equivalent circuit parameter distributions (the standard deviation and mean). Cell voltage deviation in a WESS-sized battery pack (> 21k cells) was studied using Monte Carlo simulation through a proposed cell level battery simulator. Both experiments and simulations reveal that high cell voltage deviation emerges at the low and high state-of-charge zones where the cell internal resistance has a large value and large extent of deviation.
