Lithium batteries are classified as incorporating hazardous materials because they can, in rare circumstances, present a risk of thermal runaway which can lead to explosion. Here are some explanations on this phenomenon and the sequence of events, in particular chemical, which occur. Use case We will take as an example a battery module equipped with NMC cells, which are still… Read More »Lithium battery and risk of thermal runaway
The BMS (Battery Management System) is the electronic system found inside battery packs and modules. What data is available in this equipment? Here, we will focus on the six vehicles that are statistically the most commonly found in repair or dismantling in France, due to their market launch date and production volume. Voltage, temperature, SOC (State of Charge), SOH (State… Read More »Which data are available inside BMS ?
The topic of Lithium battery safety concerns us all today. Being a complex subject, it requires research that leads to patents. This article analyzes the status of patents filed on this topic. Primarily integrating battery cells designed and manufactured in Asia, European companies logically focus on the safety of battery modules and packs.The Holy Grail of advanced research is being… Read More »European research on battery security
As the electric vehicle (EV) industry continues to evolve, there is growing evidence that high-voltage battery packs in electric cars often outlast the vehicles themselves. According to research highlighted in Electrek, many EV batteries maintain a substantial portion of their original capacity, even after the car has reached the end of its functional life. This extended battery life is primarily… Read More »Why Electric Car Batteries Outlast Vehicles, But Not in Trucks
The article from batterytechonline.com opens with a rather dramatic take, but it’s relevant to later event which is beeper explosion in Lebanon.In this case, the supply chain was compromised, replacing legitimate batteries with explosive devices.The article emphasizes the ongoing safety concerns surrounding counterfeit batteries. Let’s focus on the automotive sector. Make no mistake: the supply chain is meticulously managed by… Read More »Highlight about battery safety risk due to counterfeiting
