Lithium-ion batteries power devices ranging from smartphone and laptops to electric vehicles; highlighting how essential they are to our everyday lives. However, despite their widespread use, safety concerns persist. Here, battery thermal runaway can lead to catastrophic explosions, fire and generation of toxic smoke. Therefore, mitigating these risks will be essential for the mass market … Read more

Current Limit Estimation

There are a number of reasons to estimate the charge and discharge current limits of a battery pack in real time: Hence this is a key function of the Battery Management System (BMS). The difficulty is that the current limits are dependent on a number of factors, for the cell alone we should consider the … Read more

10 things about SSBs that you are often not told

Author Dr. Simon Madgwick of Nuvvon Inc. As an overview, this post cannot cover every possibility or explain in depth. Nonetheless these 10 topics give a reasonable overview of solid-state batteries in terms of what is less transparent in the publicity and hype of solid state.

Cell Level Fusing

Accelonix cell wire bonding

When we connect cells in parallel to increase the capacity we might also want cell level fusing. This fusing being by definition designed to disconnect a cell that for some reason is sinking or delivering high currents. The fusing can be inside the cell and sealed or external to the cell, sometimes both internal and … Read more

Battery Management System

Batteries are the heart of an Electric Vehicle but the Battery Management System is more like the brain which keeps the Heart pumping out electricity to the Motor safely and at required output. Electric
