In this article, we'll first define battery quality and related concepts such as battery failure and reliability. Finally, we'll outline one approach that our startup, Glimpse, sees for this problem.
In summary, both senses of battery quality (defectiveness and conformance) are critical determinants of battery failure and thus the financial success of cell and EV production endeavors. We revisit battery quality in the “Managing battery quality in production” section.
Exponent's understanding of all battery chemistries and their applications allows for streamlined failure analysis investigations to quickly arrive at the root cause of battery failures.
Throughout this section, we use the example of electrode overhangs (subsequently referred to as simply “overhang”) as a canonical example of a battery quality issue. Insufficient overhang may cause lithium plating, which may cause an internal short and, in extreme cases, thermal runaway 52, 74, 75.
These articles explain the background of Lithium-ion battery systems, key issues concerning the types of failure, and some guidance on how to identify the cause(s) of the failures. Failure can occur for a number of external reasons including physical damage and exposure to external heat, which can lead to thermal runaway.
Beck et al. 80 reviewed the primary drivers of nonconformance in batteries and battery production. Lack of conformance to the design may not directly cause battery failure; for instance, a key quality indicator such as the distribution of cell energy may be larger than desired but still fall within an acceptable band.
Aside from headline-grabbing safety events, battery quality issues can have outsize impacts on the reliability of battery-powered devices (Fig. 1b). For instance, an EV pack typically consists of hundreds or thousands of cells arranged in series and in parallel, often combined into modules.
The design principles of high voltage wiring harness for new energy vehicles, including strengthening wiring harness layout, material selection, manufacturing process, and analyzing the performance.
The main goals are: x shortening the design phase of the product x shortening the process planning time x lowering the costs for the system assembly and x reducing the weight of the battery.
A battery management system (BMS) is an electronic system designed to monitor, control, and optimize the performance of a battery pack, ensuring its safety, efficiency, and longevity.
The battery management system architecture is a sophisticated electronic system designed to monitor, manage, and protect batteries. It acts as a vigilant overseer, constantly assessing essential battery parameters like voltage, current, and temperature to enhance battery performance and guarantee safety.
The main objectives of a BMS include: The BMS continuously tracks parameters such as cell voltage, battery temperature, battery capacity, and current flow. This data is critical for evaluating the state of charge and ensuring optimal battery performance.
Battery management system (BMS) is technology dedicated to the oversight of a battery pack, which is an assembly of battery cells, electrically organized in a row x column matrix configuration to enable delivery of targeted range of voltage and current for a duration of time against expected load scenarios.
While there are many methods to categorize BMSs, today, we'll classify them based on how they are installed and operate on the cells or modules across the battery pack. Centralized BMS Architecture: This architecture is characterized by one central BMS in the battery pack assembly that all the battery packages are connected to.
There are two primary types of battery management systems based on their design and architecture: Features a single control unit managing the entire battery pack. Simplifies data collection and control but may face scalability challenges for larger systems. Employs a modular architecture where smaller BMS units manage groups of battery cells.
Centralized battery management system architecture involves integrating all BMS functions into a single unit, typically located in a centralized control room. This approach offers a streamlined and straightforward design, where all components and functionalities are consolidated into a cohesive system. Advantages:
Battery production has been ramping up quickly in the past few years to keep pace with increasing demand. In 2023, battery manufacturing reached 2. 5 TWh, adding 780 GWh of capacity relative to 2022.
Just as analysts tend to underestimate the amount of energy generated from renewable sources, battery demand forecasts typically underestimate the market size and are regularly corrected upwards.
Battery production in China is more integrated than in the United States or Europe, given China's leading role in upstream stages of the supply chain. China represents nearly 90% of global installed cathode active material manufacturing capacity and over 97% of anode active material manufacturing capacity today.
In this second instalment of our series analysing the 2024 Battery Report, we explore the continued rise of Battery Energy Storage Systems (BESS). Described by The Economist as the “fastest-growing energy technology” of 2024, BESS is playing an increasingly critical role in global energy infrastructure.
Global sales of BEV and PHEV cars are outpacing sales of hybrid electric vehicles (HEVs), and as BEV and PHEV battery sizes are larger, battery demand further increases as a result. IEA. Licence: CC BY 4.0 IEA. Licence: CC BY 4.0 The increase in battery demand drives the demand for critical materials.
Value chain depth and concentration of the battery industry vary by country (Exhibit 16). While China has many mature segments, cell suppliers are increasingly announcing capacity expansion in Europe, the United States, and other major markets, to be closer to car manufacturers.
This also affects trends in different regions, given that 2/3Ws are significantly more important in emerging economies than in developed economies. As EVs increasingly reach new markets, battery demand outside of today's major markets is set to increase.

PoF is not the only type of physics-based approach to model battery failure modes, performance, and degradation process. Other physics-based models have similar issues in development as PoF, and as such they work best with support of empirical data to verify assumptions and tune the results.
Levy et al. analyzed the top event (battery failure) through FTA, and four factors affecting the reliability of the battery system are obtained, namely failure probability, performance, time, and operating conditions. Qi et al. used the Rheology-Mutation Theory and FTA methods to analyze the safety of LIBs.
Regarding the LIBs tests as executable and quantifiable evaluation indexes, we weighted the 29 battery tests by AHP according to the critical importance of related basic events. The results show that the weights of the BMS reliability test and tests related to mechanical safety are the highest, which are 0.05419 and 0.04829, respectively.
