What Happens if a Cell goes into Thermal Runaway?

battery cell in thermal runaway

Author: Nrusimhan Seshadri, Balance Batteries Thermal hazards of (Li-ion batteries) LiB’s are well known. The spontaneous exothermic release of energy from LiBs when subjected thermal, mechanical and/or electrical abuse is referred as thermal runaway. Though the chances of thermal runaway in modern EV’s are extremely low, the danger posed  by EV battery fires can’t be … Read more

What is Calorimetry?

adiabatic calorimeter designed for battery testing

Author: Mario Toubes-Rodrigo, Application Specialist, H.E.L Group Calorimetry is a branch of thermodynamics that deals with heat transfer quantification. Heat can be transferred during a variety of processes, such as chemical reactions, phase changes, or dissolution of solutes in a solvent. Calorimetry follows the first law of thermodynamics, which states that energy cannot be created … Read more

Aluminium 4680 Cell Can Structural Performance

aluminium 4680 cell case from Speira

Recent industrial and academic studies have shown that aluminium cell housings can provide several benefits in terms of thermal management and gravimetric energy density in particular1,2,3. However, as Cell-To-Pack and Cell-To-Chassis approaches arise the battery cell and therefore, the battery cell housing, become part of the structure of the battery electric vehicle contributing with their … Read more

Using an ECM to Model HiPot Tests

circuit schematic for HiPot test modelling

Author: Siddharth Kurwa A DC high-potential test (HiPot) is used to detect manufacturing defects in the electrode stack/jelly roll. During the test, a high voltage (orders of magnitude higher than the cell operating voltage) is applied to the cell to screen out early-in-life and latent risks from the production cell population. It is preferred to … Read more

Aluminium Busbar Products

aluminium busbars as used on a battery module

for Cell Contacting Systems and Busbars Aluminium busbar products are used in manifold applications in batteries and battery systems due to their favourable structural, physical, and chemical properties. When it comes to cell contacting systems and busbars, electrical (and thermal) conductivity are decisive for balancing component resistance and cross-section to meet the designed space.
