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...

E-bikes are integrating lithium batteries to meet the demands for higher power density, longer life cycles, and improved safety. With emerging infrastructures such as Internet of Things (IoT), e-bikes are facing rapid development, from hardware assembly to service systems. This article provides an overview of MPS’s power products that provide simple ways to improve and redefine e-bikes. In a ba...

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...

When designing a battery management system (BMS), designers can face challenges when obtaining an accurate estimate of the battery’s state-of-charge (SOC), which is the level of a charge a battery has in relation to its capacity. This article is the second of a two-part series discussing SOC estimations. Part I explored the complex application of battery conditions in SOC estimation, as well one ...

The increasing adoption of lithium-ion batteries is boosting growth in e-mobility, medical, and robotics markets. Moreover, current application requirements are driving the adoption of larger battery packs with an extended range, longer life, and superior power capabilities. To guarantee excellent performance, it is vital to address the challenge of estimating a battery’s internal state in ...

Converters are one of the most simplistic and necessary devices in modern electronics. As their name implies, converters are meant to convert a given value to a target value. This functionality is vital for any system where connected devices may not have specifications that perfectly match one another, and they can be implemented in smartphones, smart trackers that can quickly communicate location...
