Lithium-ion batteries (LIBs) are complex electrochemical and mechanical systems that are the subject of dozens of international safety standards. In this FAQ, we’ll discuss the key environmental aspects of LIB safety, review the top 5 LIB safety standards, and consider the use of custom-battery testing rooms for the safety of testing personnel. Many of the…
Battery Power Tips
How fast can Li-on batteries be charged?
The speed at which a battery can be recharged is measured using the ‘C-rate,’ where ‘C’ is the battery’s capacity in mA or A. At a 1 C rate, a battery can be completely recharged in one hour. The speed of charge primarily depends on the voltage. For example: For small batteries used in portable…
What battery chemistries are used in grid-scale energy storage?
Expansion of grid-scale energy storage is important to enable the transition to variable renewable energy (VRE) sources such as wind and solar, and a green energy economy. The use of battery energy storage systems (BESS) is a key to enabling the growing penetration of VREs. BESS installations are classified as behind-the-meter (BTM) or front of…

Battery test system boosts safety, performance of electric vehicles
A new Battery Test System (BTS) for electric vehicle (EV) testing is designed to help tier-one suppliers and automakers adapt to the complexity and scale of EV battery testing through enhanced customization, automation, and connection of data across the entire battery test workflow to ensure performance and accelerate time to market. Batteries are at the…
Solid-state EV batteries – are we there yet?
The short answer is ‘no.’ We might be getting closer, but there’s still no guarantee that we’ll get there soon. Some automakers are looking at 2024 for the introduction of solid-state batteries in EVs, but others don’t see that happening until 2030. Expectations are high but unfulfilled. This FAQ reviews the anticipated benefits of solid-state […]
