When designing a battery into an EV, you must perform rigorous testing to understand a battery’s performance. Electric vehicles (EVs) accounted for 13% of global vehicle sales in 2022 and are forecasted to reach 30% of global vehicle sales by 2030. The industry needs to continue working on making EVs affordable to support this transition…

Testing batteries for an evolving world
Battery testing enables vehicle manufacturers, owners, and researchers to make informed decisions, optimize vehicle performance, and enhance overall user experience. Demand for electric vehicles is amping up. Every one of these vehicles needs large batteries, and the industry is responding by building plants. Energy.gov forecasts that by 2030 electric vehicle battery manufacturing capacity in North…
EV battery tests involve lots of power
In a video, EE World spoke with a power-supply applications engineer about why RV batteries use such high voltages and how to test them. Batteries are perhaps the most expensive component of an electric vehicle. Typically producing 800 V to 900 V, batteries deliver the power needed move the vehicle. Of course, EV batteries need…
How is functional safety defined & implemented for batteries in EVs and BESS?
Li-ion batteries can store large amounts of energy, and they can support high rates of power delivery. They are the preferred energy storage technology for EVs and large battery energy storage systems (BESS). But if not properly managed, they can also present safety hazards. That makes functional safety a critical consideration when designing large Li-ion…
Battery-life-boosting ICs extend life of non-rechargeable Li-ion coin cells
Nexperia has just introduced the NBM7100 and NBM5100, revolutionary new types of battery life boosting ICs designed to extend the life of a typical non-rechargeable lithium coin cell battery by up to 10x compared to competing solutions while also increasing its peak output current capability by up to 25x compared to what a typical coin…
How do liquid metal batteries fit in EV and BESS designs?
Liquid metal batteries are being developed primarily for battery energy storage system (BESS) systems but may find future applications in electric vehicles (EVs) and wearables and portable devices. The first commercial BESS using a liquid metal battery is expected to become operational soon, but the longer-term outlook for large-scale market penetration remains cloudy. The first…
What’s the difference between batteries for power tools?
There’s more variety available in power tool batteries than might be expected. Of course, various rechargeable Li chemistries dominate, and battery management systems (BMS) are critical, but there are also power tool batteries that can automatically switch their output voltage to suit the needs of specific tools; thermal management can be important for both chargers…
What are the different battery types for specific applications?
In this article, we will learn how to choose a battery according to the specifications and requirements of your application. Some applications need more power, and some need to be cheap with less power. There are various factors and parameters that to consider when choosing the best battery for your application. No one battery is…
Battery configurations (series and parallel) and their protections
A single cell is not sufficient for some devices. To achieve the desired voltage, the cells are connected in series to add to the voltage of the cells. The cells are connected in parallel to reach the desired capacity by adding ampere-hour (Ah) to reach the desired capacity. This combination of cells is called a…
