“…For the BMS deployment, the efficiency of the DC-to-DC converter is directly proportional to the efficiency of the BMS because it is directly connected to the battery pack. In our previous paper [8], it was mentioned that the total efficiency of DC-to-DC converter is 92.74%; further analysis was conducted to verify this in this study. The BMS deployed to the UGV was comprehensively analyzed.…”

“…This cost is inline with the components needed to realize an active cell balancing approach whereas passive balancing requires only a filter circuit and a bleeder also known as discharge resistor to actuate cell balancing as highlighted in [8]. The proposed approach in [8] which is the extension of this paper proves that passive balancing has high implementation viability and have high balancing implementation accuracy. Moreover, it can correct the longterm discrepancy of self-discharge current on a cell-to-cell basis.…”

“…These factors result in an early aging effect or cell degradation. All BMSs aim to monitor, control, and protect cells in a pack for efficient, state-of-the-art, and safe applications, as highlighted in our previous paper [8]. There are three topologies for conventional BMS: 1) centralized, 2) distributed, and 3) modular; these topologies can be used in combination as hybrid topology.…”

This paper proposes design and implementation of a battery management system (BMS) for the industrial internet of things (IIoT) enabled applications. The hardware and software development of this BMS is briefly presented in this paper. In terms of hardware development, the presented BMS have modular topology and has 1) high fault tolerance and 2) has exceptionally flexible deployment owing to its topology having multiple local management units (LMUs) connected to a central management unit (CMU). This hardware design approach aims to address the overall design efficiency and cost trade-off of BMS deployment. The hardware design efficiency is tested using actual deployment. In terms of fault tolerance using 1 -3 LMUs at fault, the voltage monitoring accuracy is maintained for each LMUs. An average of 0.00017 V, 0.0008 V and 0.001 V voltage difference is yielded for 1, 2, and 3 modules at fault respectively. Additionally, core BMS sub-circuit is tested to verify hardware design efficiency such as the DC-to-DC converter which yielded 92.74%. Furthermore, the CMU is integrated with a wireless communication circuit that enables IIoTbased applications such as the emerging edge-based, and a plethora of intelligent deployment. In terms of software, the presented BMS aims to realize state-of-the-art processing through IIoT based approach. For software testing and verification, the BMS is deployed to an unmanned ground vehicle (UGV). The signal stability is tested for UGV based application at a 3500s deployment time whereas an average of 0.0010V voltage difference is yielded. This is verified using time markers which is further analyzed using softwarebased signal processing and acquisition simulation. Concisely, the proposed BMS aims to converge IIoT applications to its actual deployment. The proposed BMS is designed, implemented, and successfully deployed to test its viability both in the simulation platform and actual deployment.INDEX TERMS Battery management system, edge processing, industrial IoT, lithium-ion, modular architecture.

In order to effectively solve the problem of energy autonomy of patrol robots in open-air working environment and free them from the limitation of power lines on their activity range. In this article, a solar-powered patrol robot based on a robot operating system is designed. The system adopts a modular design, using a master-slave distributed controller to control the robot's motion, and building an intelligent sensing system for the robot with various sensors. Meanwhile, flexible thin-film solar cells and lithium batteries form a folded multi-mode power supply system, which solves the problem of timely power supply. In addition, a simple and practical human-computer interaction interface is designed to facilitate viewing the robot's status. Finally, in order to verify the performance of the robot, the stability of the designed solar-powered patrol robot is verified through different experiments, which has a reference value and practical significance for the development of patrol robots.
