Battery safety standards and testing
Lithium-ion battery (LIB) safety is a major concern for designers. LIBs are generally safe to use if they have been properly manufactured and are integrated correctly into systems. However, the use of sub-standard materials and the possibility of manufacturing or design defects can result in hazardous conditions. As a result, there are many global safety […]
Battery management system targets robotics, AGV, 2/3-wheeler apps
The new i-BMS Battery Management System from Lithium Balance, acquired by Sensata earlier in the year, is a cell chemistry agnostic, compact, integrated BMS developed for the cost-optimized mass-production of applications up to 60 V, such as two and three-wheelers, automated guided vehicles (AGVs), and robotics. The i-BMS is a long-term solution for customers who […]
18650, 21700, 30700, 4680 and other Li-ions – what’s the difference?
There are many sizes of cylindrical lithium-ion (Li-ion) cells, and the number of sizes continues to grow. Some are optimized for use in simple devices such as toys and flashlights; others are mainly found powering portable electronics and electric vehicles. This FAQ begins by reviewing the broad landscape of cylindrical Li-ions, including protected and non-protected…

Understanding battery management systems
A battery-management system (BMS) is an electronic system or circuit that monitors the charging, discharging, temperature, and other factors influencing the state of a battery or battery pack. It’s used to monitor and maintain the health and capacity of a battery. Today’s BNS devices are advanced and will often provide pop-up notifications as you’ve likely…
Energy storage by the Farad, Part 2: Supercapacitors & batteries
For operating and backup power and energy storage, engineers can choose among batteries, supercapacitors, or “best of both” hybrid supercapacitors. The previous part of this article established the context for supercapacitors and explained their structure in simplistic terms; obviously, this is a component with deep physics, chemistry, materials-science considerations, and manufacturing issues. The first widely […]
