Battery-powered applications, which have become indispensable over the last decade, require a certain level of protection to ensure safe use. This safety is provided by the battery management system (BMS). The BMS monitors the battery and possible fault conditions, prevents any hazardous situation due to the battery or its surroundings, and ensures that there is an accurate estimation of the batte...

Battery state-of-charge (SOC) and state-of-health (SOH) are crucial factors that must be estimated to determine a battery’s available capacity and how well it performs compared to when it was new. This is especially important in applications such as e-scooters, where a battery suddenly shutting down or experiencing a failure could result in an accident. This article will introduce battery SOC and...

Battery management refers to the critical task of monitoring, protecting, and controlling batteries, particularly with rechargeable battery packs, where many batteries are connected in series or parallel. A battery management system (BMS) consists of a battery monitor, microcontroller (MCU), and fuel gauge. The BMS ensures safe, reliable, and optimal operation by protecting the system and battery,...

Battery-powered devices are integral to modern technology, and have revolutionized our ability to take devices with us anywhere and everywhere. Medical devices such as glucose meters and pacemakers allow people to thrive with minimal inconvenience, and devices such as portable power tools and radios can be used to coordinate efforts for disaster relief. In our day-to-day lives, we use battery-powe...

Reliable and affordable energy sources are required to power the economy and meet daily needs. Without these energy sources, economic growth and development stalls. Dependence on foreign sources for energy can also lead to vulnerability to geopolitical conflicts. With ongoing concerns regarding climate change, ensuring energy security has environmental implications as well, with efforts to increas...

Modern life has become more convenient due to battery-powered applications for electric tools, vacuum cleaners, electric bikes, and outdoor power supplies for camping. As wireless charging continues to be more widely used in applications, lithium battery safety is a growing concern, so designers are looking to develop battery monitoring and protection solutions. A battery pack is made up of multi...

Battery-powered applications have become commonplace over the last decade, and such devices require a certain level of protection to ensure safe usage. The battery management system (BMS) monitors the battery and possible fault conditions, preventing the battery from situations in which it can degrade, fade in capacity, or even potentially harm the user or surrounding environment. It is also the r...

A battery management system (BMS) is made up of a series of electronic devices that monitor and control a battery’s operation. The main elements of a typical BMS are the battery monitor and protector, the fuel gauge, and the main microcontroller (MCU) (see Figure 1). One of the most important parameters for a BMS is the accuracy of its state-of-charge (SOC) estimation. Errors in SOC estimat...
