Enhancing Li-Ion Battery Safety: The Imperative of Rupture Disc Integration for Overpressure Mitigation Author: OsecoElfab Introduction The rapid growth of Li-Ion batteries in various industries, including electric vehicles, portable electronics, and renewable energy storage, brings to the forefront a critical safety concern: thermal runaway and its potential to trigger overpressure explosions. To address this imminent … Read more
High Voltage automotive training comes in several different flavours, and all our courses are made relevant to the work you are going to do using examples and scenarios from our long experience in the real world of vehicle development engineering. Level 1 is basic hazard awareness and gives you an understanding of why the industry is going EV, … Read more
Author: Nrusimhan Seshadri, Balance Batteries Having looked at the challenges and regulatory standards relating to fire hazards posed by Li-ion batteries in the previous article, in this article we will have a look at some of the fire mitigation strategies deployed across 10 BEVs in the current market. The choice of thermal barrier materials (TBMs) for a … Read more
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
Unravelling Benefits, Limitations, and Optimal Operating Voltage for Enhanced Energy Storage, by Christopher Autey In the ever-evolving landscape of renewable energy and advanced energy storage solutions, Lithium Iron Phosphate (LiFePO4) batteries have gained widespread acclaim for their exceptional performance, reliability, and versatility. Among these, the 12V LiFePO4 batteries have emerged as a popular choice for … Read more
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
If you are entering into manufacturing cells then you will want to understand Lithium Battery Manufacturing Equipment CAPEX. The detailed report is available from Bonsai Technology. This analysis is for a prismatic cell case and is an average. Note that this depends on: Therefore, it is a first indicator in the breakdown of a total … Read more
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
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
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. However, … Read more
