The Rise of AI driven BMS Revolutionizing Li ion Battery Performance

IEEE, 2024

—Accurate measurement of the number of cycles of Li-Ion batteries is essential for the battery management system (BMS). Virtual State of Health (SOH) estimation is increasingly attracting attention because to the simplicity of its structure, its flexibility in adapting to online usage, and its independence on battery designs, in contrast to direct methods of measurement and model-based methods. At first, data-driven methods are used to derive a reliable health indicator (HI) that may be used to measure the status of health (SOH). Afterwards, a machine learning model is created to establish the relationship between the Health Index (HI) and the State of Health (SOH). This study proposes employing a partial charge and discharge current sequence based on data analytics of battery aging data. Next, the data is inputted into the KNN algorithm, known for its rapid learning speed and strong generalization capabilities. The estimation accuracy is fully tested by considering the selected charging and discharging capacity. The efficacy of the suggested strategy is confirmed by testing on an openly available dataset. This study offers an analysis of the methodologies used to estimate the state of health (SOH) of batteries, highlighting their primary benefits and identifying their limits in terms of real-time compatibility with automotive systems, particularly in hybrid electric applications.

ARTIFICIAL INTELLIGENCE-BASED BATTERY MANAGEMENT SYSTEMS FOR LI-ION BATTERIES

Trans Stellar Journals, 2021

Li-ion batteries are highly advanced as compared to any other commercially available rechargeable batteries due to their gravimetric and volumetric energy. With the rise of the electric vehicle market, battery management systems play a key role in the industry to deliver finer performance and support longer ranges. Battery packs need to be monitored in realtime to maintain the safety, efficiency and reliability of the overall system. The crucial parameters that need to be determined for efficient and safe working include State-Of-Charge. This is achieved by monitoring the current, voltage, temperature, etc. which are then processed using various algorithms. The SoC of the battery pack is determined using ANN/AI-ML based control system based on the dataset collected/simulated for the individual Li-ion cells. To ensure voltage/SoC remains the same for the multiple cells in the battery pack, a single inductor method of cell balancing is used. This paper focuses on the hardware aspects as well as the software aspects of the battery management system with a short analysis of basic requirements and topologies. Implementation and development aspects are also elaborated

IntellBatt: Towards smarter battery design

2008

Battery lifetime and safety are primary concerns in the design of battery operated systems. Lifetime management is typically supervised by the system via battery-aware task scheduling, while safety is managed on the battery side via features deployed into smart batteries. This research proposes IntellBatt, an intelligent battery cell array based novel design of a multi-cell battery that offloads battery lifetime management onto the battery. By deploying a battery cell array management unit, IntellBatt exploits various battery related characteristics such as charge recovery effect, to enhance battery lifetime and ensure safe operation. This is achieved by using real-time cell status information to selects cells to deliver the required load current, without the involvement of a complex task scheduler on the host system. The proposed design was evaluated via simulation using accurate cell models and real experimental traces from a portable DVD player. The use of a multi-cell design enhanced battery lifetime by 22% in terms of battery discharge time. Besides a standalone deployment, IntellBatt can also be combined with existing battery-aware task scheduling approaches to further enhance battery lifetime.

Smart batteries for automotive applications

Integrated Computer-Aided Engineering

The US Army has been pursuing the development of a Smart Battery development as part of its ongoing efforts for reducing operation and maintenance costs of the Army's ground vehicles. As a consequence of this effort, it became evident that the smart battery has a much broader significance well beyond that of an operations and maintenance cost reduction exercise. In effect, the traditional concept of a battery as a simple energy storage unit yielded to that of a critical component in a power management subsystem. A smart battery is a standard battery having an embedded microcontroller that monitors key sensor inputs, processes and stores the derived information and reports the results on a shared data bus. In that arrangement, the smart battery serves the function of a status-reporting load-leveling component of the overall subsystem. As such, the smart battery becomes an essential contributor to a digital nervous system in vehicle systems. The smart battery is creating a new way of defining what a battery is. It is evident that the use of smart batteries has a direct bearing on vehicle readiness and enables system-wide planning, organization and control of the power and energy resources.
